The aim of this study was to characterize the antennal morphology of Osmoderma eremita, a threatened scarab beetle inhabiting tree hollows. O. eremita males produce a sex pheromone, (R)‐(+)‐γ‐decalactone, responsible mainly for the attraction of females but also other males. Gross and fine morphology of microstructures including sensilla, microsculpture and pores were analyzed using Scanning Electron Microscopy. The antenna of O. eremita showed the typical lamellicorn shape of scarab beetles, with a basal scape, a pedicel, a funicle composed of five antennomeres and a club composed of three lamellae. Six different subtypes of sensilla chaetica (Ch.1 ? 6), Böhm sensilla (Bo), one subtype of sensilla basiconica (Ba.1), two subtypes of sensilla coeloconica (Co.1 ? 2), two subtypes of sensilla placodea (Pl.1 ? 2), pores and peculiar folds were described. The two sexes did not show any significant differences in the occurrence and number of the sensilla placodea, known to be responsible for the pheromone reception. Instead, some sexual differences were found on the occurrence and topology of three different microstructures: (1) one subtype of sensillum chaeticum (Ch.2) occurring on the pedicel only in males; (2) a characteristic pore occurring on the funicle only in males; (3) a peculiar fold occurring on different antennomeres of the funicle in the two sexes, on the fourth in males and on the fifth in females. A comparison between sensilla of O. eremita and those of other Scarabaeoidea is provided. Microsc. Res. Tech. 79:178–191, 2016. © 2016 Wiley Periodicals, Inc. 相似文献

Houseflies, Musca domestica, obtained from a high-larval-density culture were significantly (ca. 1.5 times) smaller than those from a low-larval-density culture. The same held true for their antennae and maxillary palps. Structure, number, and distribution of sensilla on antennae and palps of small and large flies were investigated using Scanning electron microscopy and Transmission electron microscopy. In each funiculus three pits were present, two (Type I) consisting of several compartments and one (Type II) of one compartment. Four types of olfactory sensilla were detected: trichoid sensilla on the funiculi, basiconic sensilla on funiculi and palps, grooved sensilla on funiculi and in pits Type I, and clavate sensilla on funiculi and in pits Type II. Type I pits also contained striated sensilla (presumably hygroreceptors). Mechanosensory bristles were present on scapes, pedicels, and palps. Noninnervated microtrichia were found on the palps and all antennal segments. The large houseflies possessed nearly twice as much sensilla as the small flies. So far, we did not observe differences in behavior between small and large flies. We assumed that small flies, being olfactory less equipped than large flies, may be able to compensate for this by, e.g., visual cues or by their olfactory sensilla being more sensitive than those of large flies. To be able to answer these questions careful studies have to be done on the behavioral responses of small and large flies to environmental stimuli. In addition, electrophysiological studies should be performed to reveal whether the responses of individual sensilla of flies reared under different conditions have been changed. 相似文献

The bean bug, Riptortus pedestris is a major pest of bean pods and some tree fruits in north‐east Asian countries. Scanning electron microscopy was conducted to investigate the morphology and distribution of antennal sensilla of R. pedestris to help in understanding the sensory mechanisms of the bug. Average antennal lengths of male and female R. pedestris were 11.00 mm and 9.84 mm, respectively, consisting of four distinct segments, scape, pedicel, basiflagellum, and distiflagellum. Based on the gross appearance, the antennal sensilla were classified into four major types (trichodea, basiconica, chaetica, and coeloconica), which could be further classified into four trichoid, three basiconic, four chaotic, and two coeloconic subtypes, based on their size, tip shape, presence of socket, and surface structure. Among them, two subtypes of trichoid sensilla, all three subtypes of basiconic sensilla, four subtypes of chaetic sensilla and two subtypes of coeloconic sensilla had numerous pores along the surface, suggesting their olfactory function. Nine subtypes (2 trichoid, 1 basiconic, 4 chaetic, and 2 coeloconic subtypes) showed a distinct socket structure at the base. Among the four antennal segments, the distiflagellum possessed highest number of sensilla. Trichoid sensilla were most abundant, followed by basiconic, chaetic, and coeloconic sensilla. Each subtype of sensilla exhibited distinct distribution profile along the four antennal segments. Two subtypes of trichoid sensilla, one subtype of basiconic sensilla and one subtype of chaetica sensilla were distributed on scape, pedicel, and basiflagellum, whereas distribution of other subtypes of sensilla was confined to basiflagellum and distiflagellum.

Morphology of antennal sensilla and their distributions were investigated in male and female adults of two tortricid moths, Cydia pomonella and C. succedana using scanning electron microscopy. The antennae of both sexes of the two species were filiform, and the overall lengths of the antennae and the number of consisting segments were greater in males than in females. Six types of sensilla (s.) were identified from the antennae of both sexes in the two species: s. trichodea, s. basiconica, s. coeloconica, s. auricillica, s. chaetica, and s. styloconica, in varying numbers and distribution along the antennae. Among them, surface of four sensilla types (s. trichodea, s. basiconica, s. coeloconica, s. auricillica) were multiporous in the two species, indicating that the primary function of these sensilla is olfactory. The s. trichodea were the most numerous on the antennae in both sexes of the two species. Male C. pomonella has a greater number of s. trichodea than the female. The four sensilla types were further divided into different subtypes in the two species; s. trichodea into three subtypes, s. basiconica into two subtypes, s. coeloconica into two subtypes in C. pomonella and one subtype in C. succedana, and s. auricillica into two subtypes. Sexual dimorphism was observed in the subtypes of s. trichodea. The long subtype of s. trichodea occurs only on male antennae, whereas the short subtypes mainly on female antennae. These findings would be helpful for further studies on detailed chemo‐receptive functions of each subtype of the antennal sensilla. 相似文献

Scaphoideus titanus Ball (Hemiptera: Cicadomorpha) is a leafhopper vector of a phytoplasma disease, the Flavescence dorée (FD), belonging to the vine yellows group. A scanning and transmission electron microscope study has been carried out to investigate the antennal sensory structures. The first two segments, the scape and the pedicel, are short, covered by cuticular scales and devoid of sensilla, with exception of some scattered hairs on the pedicel. The flagellum consists of a unique, elongated segment in which numerous subunits can be recognized, being separated by a sort of cuticular crown. The proximal five subunits bear most of the sensilla. We discovered the presence of single- and double-walled coeloconic sensilla, campaniform sensilla, basiconic sensilla, and trichoid sensilla. A scolopidium is located within the proximal region of the flagellum. Ultrastructural investigations suggest that the antennal sensilla could be involved in the perception of air-borne vibrations, temperature, and humidity variations. The most relevant feature is the extreme reduction of the olfactory sensilla, both in terms of number of sensory structures and sensory neurons per sensillum. The strong reduction in antennal olfactory sensilla to which this specie has undergone is discussed as possible consequence of the specificity toward the host plant. 相似文献

ABSTRACT The fat body (FB) of insects is where yolk proteins are synthesized. Therefore, relationships between the FB and oogenesis were studied in nurse workers, virgins, and physogastric queens of Melipona quadrifasciata anthidioides, a stingless bee in which the workers produce and lay eggs while provisioning brood cells. The relationships between FB and oogenesis, as well as the routes of materials from hemolymph to the oocytes, were studied through the cytochemical detection of lipids by osmium imidazole (OI), carbohydrates by ruthenium red (RR) and basic proteins by ammoniacal silver (AS). The results show differences in the presence of the studied materials in FB trophocytes and ovary of the classes of females studied and oogenesis phases. Material that tested positive for the treatments was detected among the classes of individuals studied in both, trophocytes and oocytes, and in the route of those materials from hemolymph to the oocytes. The differences found among the individual classes indicate relationships with the nutrition and adaptation to the parsimonious use of nutrients in the metabolism of reproduction. Microsc. Res.

Scanning electron microscopy revealed the presence of a number of cuticular sensillae on the head of different larval stages of the “Muga” silk moth, Antheraea assamensis. These include four types of sensilla trichodea, bead‐like folded sensilla, two types of sensilla basiconica, and sensory pegs. The study seems to be the first attempt in describing the morphology and distribution pattern of the cephalic cuticular sensillae of different larval stages of the silk moth Antheraea assamensis, an indigenous species of Northeast India. The possible significance of the sensillae in searching behavior of the larval stages during feeding is discussed with the help of available literature. Microsc. Res.

The aim of this study, therefore, was to investigate the ultrastructure of gyrodactylid sensilla and to ascertain how these may be employed in the colonisation of new hosts using the Gyrodactylus gasterostei Gläser, 1974—Gasterosteus aculeatus L. model. As Gyrodactylus has no specific transmission stage in its life‐cycle, movement between hosts must be achieved by strategies employed by the adult. This study suggests that certain sensilla, presented for the first time in Gyrodactylus gasterostei, may serve as chemoreceptors and mechanoreceptors and possible photoreceptors. The results of this study provide photographic data using scanning electron microscope (SEM) and transmission electron microscopy (TEM) concerning the sensory structures that are found on the tegument and in the sub‐tegumental zone of G. gasterostei that infect 3‐spine sticklebacks (Gasterosteus aculeatus L.). For this reason, it is vital to understand the factors underlying transmission to a new host, and a detailed, ultrastructural examination of the sensory structures that are used may improve current understanding of the receptors that Gyrodactylus species employ to interpret both their host and ambient environments. Such information may assist in the interpretation of transmission behaviors, particularly their responses to chemical or physical cues which gyrodactylids employ in host location during the transmission process.

Scanning electron microscopy of different larval stages of the muga silk moth Antheraea assamensis revealed the presence of sensilla chaetica, sensilla trichoidea, sensilla styloconica, gustatory sensilla, sensory pegs, placoid sensilla, etc., on their mouth parts. Some variations were observed in the number and sub‐types of sensilla in certain larval stages indicating some differences in sensitivity of the worms in different instars to the food plant and microhabitat.

Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae), a pupal parasitoid of a great number of Lepidoptera pests, has a great potential for biological control. To investigate the olfactory system of this parasitoid, we examined the morphology and ultrastructure of the antennal sensilla of both male and female T. howardi using scanning and transmission electron microscopic techniques. Antennae of male and female T. howardi were geniculate in shape, which consisted of scape, pedicel and flagellum with 5 and 4 flagellomeres, respectively. The sexual differences were recorded in the types, structure, distribution and abundance of antennal sensilla of T. howardi. Fourteen morphologically distinct types of antennal sensilla were found on the female antennae, while seventeen on the male antennae. They were: multiporous plate sensilla (MPS1‐4), chaetica sensilla (CH1‐3), multiporous trichodea sensilla (MTS), aporous trichodea sensilla (ATS1‐5), multiporous grooved peg sensilla (MGPS), coeloconic sensilla (COS), campaniform sensilla (CAS), terminal finger‐like hairy sensilla (TFI), cuticular pore (CP), and ventral sensory plaque (VSP). MPS4, ATS (3‐5), and VSP only occurred on the male antennae, while MPS2 and MPS3 only on the female antennae. The MPSs, MTS, MGPS, TFI, and CP may function as olfactory sensilla involving in detecting odor stimuli whereas the ATSs, CHs, and CAS may serve as mechanoreceptors. COS were presumed to play a role as chemo‐, thermo‐ or hygro‐receptor. The results could facilitate future studies on the biology of olfaction in T. howardi. Microsc. Res.

The chilli thrips, Scirtothrips dorsalis Hood, is a serious pest of numerous important vegetable and ornamental crops. Various signals, especially phytochemical cues, determine the behavior of the phytophagous thrips at host selection. The sensory abilities of S. dorsalis are poorly understood although the antennae of adult are known to possess important sensory structures in orther insects. In this study, the morphology, distribution, and ultrastructure of the antennal sensilla of the S. dorsalis were examined by using scanning and transmission electron microscopy. Microscopy observations revealed that adult male and female S. dorsalis possess filiform antennae. Each antenna comprises a scape, a pedicel, and a flagellum composed of six segments without clear sexual dimorphism in the number and distribution of antennal sensilla. The scape and pedicel exhibit Böhm's bristles, sensilla chaetica, and sensilla campaniform. The external structures of these organs reveal their mechanosensory function. In the flagellum, the most represented sensilla are the multiporous sensilla basiconica, which can be divided into three types of single‐walled olfactory sensilla; three types of sensilla chaetica with mechanosensory and gustatory functions; sensilla coeloconica, which possess hollow cuticular spoke channels and represent double‐walled olfactory sensilla; sensilla capitula and sensilla cavity with thermo‐hygrosensory functions; and aporous sensilla trichodea with smooth cuticula and mechanosensory function. The putative function of described sensilla is discussed in ralation to host plant selection behavior of S. dorsalis. 相似文献

The typology, number, and distribution pattern of antennal sensilla of the ground beetle Platynus dorsalis (Pontoppidan) (Coleoptera, Carabidae) were studied using scanning electron microscopy. The 4.3-4.6-mm-long filiform antennae of the beetles consist of the scape, pedicel, and nine flagellomeres. In both sexes, four subtypes of sensilla chaetica, five subtypes of sensilla basiconica, sensilla trichodea, two subtypes of sensilla campaniformia, sensilla auricillica, and sensilla coeloconica were distinguished. The possible function of the sensilla was discussed and three types of sensilla were considered as olfactory, sensilla trichodea and sensilla basiconica types 1 and 2. Olfactory sensilla form two separate, dorsal and ventral, fields of sensilla on the flagellomeres, which seems to be common in ground beetles. The total numbers of olfactory trichoid (approximately 1,000 hairs) and basiconic sensilla type 1 (1,700-1,800 pegs) on the antennae of P. dorsalis are 5-7 times higher than on the antennae of the ground beetle Bembidion lampros, suggesting that nocturnally active P. dorsalis is much more sensitive to odours perceived by these sensilla than B. lampros with diurnal activity and hunting predominantly by sight. No remarkable sexual differences in the types, numbers, and distribution of antennal sensilla were found in P. dorsalis. 相似文献

The antennal sensilla of the pine weevil (Pissodes nitidus Roel.) were observed with scanning electron microscopy and transmission electron microscopy (TEM). The weevil antenna consists of a long scape, a pedicel, and a flagellum with 10 segments; the last four flagellum segments are fused, forming the antennal club, which is densely covered by various sensilla. In both sexes, six types of sensilla, sensilla palmate 1‐4, sensilla chaetica, sensilla trichoid, sensilla basiconic 1‐2, sensilla rod‐like 1‐3, sensilla falciform, were identified. Sensilla palmate represent a unique sensillum type in the Pissodes genus, and named here after their palmate shape, also represent the most abundant sensillum type. The TEM analysis of sensilla palmate represents the first such analysis of this sensillum type, and we speculate that the sensilla have an olfactory function. The sensilla trichoid and chaetica were evenly distributed on the three or four hair bands of the club, with much lower numbers than the palmate sensilla. No significant sexual differences in the types, numbers, and distribution of the antennal sensilla were found except for the size. TEM observation indicated that sensilla chaetica and trichoid may function as olfactory sensors. The putative functions of other sensilla type were also discussed with reference to their morphology, distribution, and ultrastructure. Microsc. Res. Tech., 2011. © 2010 Wiley‐Liss, Inc. 相似文献

The current study was designed to describe the nasal turbinates of 15 heads of Anatolian shepherd dogs using the histology and scanning electron microscope. The caudal part of the nasal cavity is almost occupied by the ethmoidal concha that is related to the high dog's smelling. Keratinized stratified squamous epithelial lining of the rostral part of dorsal and ventral concha were interdigitated with the underlying lamina propria, with numerous sebaceous and sweat glands. The pseudostratified squamous epithelium lining of the middle part of the dorsal and ventral conchae had simple seromucous glands. The caudal third of dorsal, ventral, and ethmoidal conchae covered by olfactory epithelium that had three cell types; basal, supporting, and bipolar cells with mucous glands. SEM of the vestibular region shows that the dorsal conchae had a wrinkled surface with microvilli, little olfactory buds, and small sebaceous and sweat glands openings, while the ventral conchae had a lot of filiform-like microvilli. SEM of the respiratory region shows that the dorsal conchae had a little number of seromucous glands and a rosette-shape cilia, while the ventral conchae had numerous cellular cilia that cover all surface. SEM of the fundus region shows that the dorsal conchae had numerous microvilli of ciliated olfactory cells, while the ventral conchae had numerous long microvilli of ciliated olfactory cells. SEM of the ethmoidal nasal conchae shows a dense network of long microvilli of ciliated olfactory cells. We concluded that the morphological features of the dog's nasal turbinates were correlated with their environmental condition. 相似文献

Deciphering the genome of the fruitfly, Drosophila melanogaster, has revealed 39 genes coding for putative odorant-binding proteins (OBPs), more than are known at present for any other insect species. Using specific antibodies, the expression mosaic of five such OBPs (OS-E, OS-F, LUSH, PBPRP2, PBPRP5) on the antenna and maxillary palp has been mapped in the electron microscope. It was found that (1) OBP expression does correlate with morphological sensillum types and subtypes, (2) several OBPs may be co-localized in the same sensillum, and (3) OBP localization is not restricted to olfactory sensilla. The expression of PBPRP2 in antennal epidermis sheds some light on the possible evolution of OBPs. 相似文献

Experimental infections were used to track the fate of the dorsal sensilla of Merizocotyle icopae (Monogenea: Monocotylidae) from nasal tissue of the shovelnose ray, Rhinobatos typus (Rhinobatidae). Scanning and transmission electron microscopy revealed that 3 types of uniciliate dorsal sensilla exist at different times in the development of the monogenean. Type 1 sensilla have little or no invagination where the cilium exits the distal end of the dendrite and possess a ring of epidermis surrounding the cilium distal to the invagination. Type 2 sensilla have a deep invagination where the cilium exits the dendrite. Type 3 sensilla can be distinguished from the other types by the shape of the dendrite. The larvae have predominantly Type 1 dorsal sensilla, most of which are lost approximately 24 h after infection and a few Type 2 sensilla, which are retained. Additional Type 2 sensilla (termed Adult Type 2 sensilla), which are slightly different morphologically from the Type 2 sensilla of the larvae, form in later stages of development. Numerous Type 3 sensilla are unique to the dorsal surface of adults. Loss of all Type 1 sensilla upon attachment to the host, R. typus, suggests that these may be chemo- or mechanoreceptors responsible for host location by the swimming infective larvae. Type 2 sensilla appear to be important in the larvae, juveniles, and adults whereas the modality mediated by Type 3 is specific to adults. 相似文献

Anastatus japonicus Ashmead (Hymenoptera: Eupelmidae) is an important egg parasitoid of several major insect pests. To better understand its host finding mechanisms, the antennal sensilla of female wasp were investigated by scanning electron microscopy. Sensilla chaetica were found mainly on radicle and pedicel segments of the antennae. i-Type sensilla, s. campaniformia, and corneous sensilla were detected on the leeward side, while s. coeloconica and lance sensilla were presented on the windward side of the antennae. S. trichodea and s. basiconica were more abundant on the leeward side than on the windward side of the antennae. More s. placodea were found on the windward side than on the leeward side of the right antenna, while the opposite results were observed on the left antenna. Overall, more s. placodea were found on the right antenna than that on the left antenna. The numbers of s. trichodea and s. basiconica on the clava or the third flagellum antennomere of the right antenna were more than those of the left antenna, whereas their distribution patterns on the other corresponding antennomeres were reverse. Our results showed that there is a strong asymmetrical antennal sensilla distribution quantitatively and spatially between the left and right antennae. Placoid sensilla are present more on the right antenna than on the left antenna. S. campaniformia, corneous sensilla, and i-type sensilla were found only on the leeward side of the antennal clava, while their external morphology and potential functions were described and discussed in detail for the first time. 相似文献

Apanteles cypris is an endoparasitoid of rice pest Cnaphalocrocis medinalis. To better understand its host location mechanism, we examined the external morphology of antennal sensilla of A. cypris via scanning electron microscopy. The antennae of male and female A. cypris were filiform in shape, which consist of scape, pedicel, and flagellum with 18 antennomeres. Eleven types of sensilla were recorded in both sexes, including two types of chaetica sensilla, trichodea sensilla without pore, basiconica sensilla I with a tip pore, basiconica sensilla II with wall pores, basiconica sensilla III with a mastoid at the tip, coeloconica sensilla with apparent fingerlike projections, campaniform sensilla with a sprout tip pore, clavatea sensilla, smell pore, and placodea sensilla (PLA) with the multiporous cuticular structure. We also compared the morphology, number, and distribution of the sensory receptors between the two sexes. The length and width of the antennae on the males were significantly greater than that of females. In addition, males of A. cypris showed a larger number and a higher density of PLA compared to females. The morphology and structure of these sensilla were compared to that found in other braconid wasps, and their possible functions in host location were discussed. These observations could facilitate future studies on the biology of olfaction in A. cypris. 相似文献

Scanning electron microscopy on the postembryonic development of the mouthpart sensory structures of the Muga silk moth, Antheraea assamensis revealed the presence of a variety of sensilla. The types, distribution pattern of the sensilla remained almost the same in the different larval stages except for the number and dimension in some cases. The findings of the study assumes significance because the silk moth, Antheraea assamensis is a species endemic to the North Eastern part of India and very few reports are available on it. In fact, the present study provides the first report on the ontogeny of the mouth part sensilla of the silk moth species. Since mouth part sensilla and their surface micro structural characteristics are extremely important in understanding their roles in searching behavior during feeding, the present study will certainly help in developing strategies for proper rearing of this economically important insect species.

To help understand the mechanism of host discrimination during oviposition of a parasitoid wasp, Venturia canescens (Gravenhorst) (Hymenoptera: Ichneumonidae), the ultrastructure and morphology of the sense organs on the dorsal and ventral stylets of the ovipositor were examined using scanning and transmission electron microscopy. Ovipositor stylets were scanned for sense organs, because only unsheathed ovipositors are used for probing, stabbing, and host discrimination. Five types of sensilla and secretary pores were identified. Based on their pattern of innervation, the surface-dome and pitted-dome sensilla were thought to have a gustatory function and, thus, are the best candidates for host-discrimination. The arrangements of dendrites of type I and type II campaniform sensilla suggested that these acted as pressure- and mechano-receptors, respectively. Coeloconic sensilla might act as thermo-hygroreceptors, whilst secretary pores might provide lubrication during the process of stabbing for oviposition. Surface-dome sensilla were the most numerous type found followed by secretary pores, pitted-dome sensilla, and coeloconic sensilla. Almost all the sensilla and secretary pores were more numerous on the dorsal than on the ventral stylets, and the maximum number of these sensilla and secretary pores occurred on the distal end of the ovipositor stylets and decreased toward the proximal end. The surface-dome sensilla and secretary pores occurred in alternate rows while the pitted-dome sensilla were scattered all over the surface of the ovipositor stylets, especially on the sides of the stylets. 相似文献
