南美斑潜蝇成虫的生物学特性与行为

通过室内饲养观察及野外调查，研究了昆明地区南美斑潜蝇（Ｌｉｒｉｏｍｙｚａ ｈｕｉｄｏｂｒｅｎｓｉｓ）成虫的生物学特性，包括羽化、日活动规律、寿命、求偶与交配、取食和产卵。通过观察成虫的行为，发现雄虫在求偶过程中用腿节摩擦腹部摩擦器以吸引雌虫交配。在较高的种群密度下，雄虫之间在交配过程中表现出强较的攻击性。雌虫在搜索寄主时利用跗节、产卵器和喙上的感受器对寄主植物进行探查和评估。本研究的结果为斑潜蝇的

BIOLOGICAL CHARACTERISTICS AND BEHAVIOR OF ADULT SERPENTINE LEAFMINER Liriomyza huidobrensis (BLANCHARD)

The study dealt with the biological characteristics and behavior of adult serpentine leafminer Liriomyza huidobrensis (Blanchard) in Kunming, Yunnan Province. Activities, emergence, feeding, oviposition and longevity of adults were studied. Behavior of probing, mating, feeding and oviposition were described. Before feeding, females use tarsus, ovipositor and proboscis to assess the suitability of host plants. When the population density is high, some males attack other coupled males. During courtship, males scrape stridulatory apparatus to attract mating. The results of this study will provide some valuable information for future control methods such as plant resistance, genetic control and mating disturbance.
