一种国内茉莉新害虫——茉莉丽瘿螨

2011年在海南省海口市进行瘿螨种类资源调查时,在茉莉[Jasminum sambac (Linn.) Aiton]叶片上采到一种瘿螨,经鉴定为茉莉丽瘿螨(Calacarus jasmini Chakrabarti et Mondal,1978,)属于蜱螨亚纲(Acari)瘿螨科(Eriophyidae)叶刺瘿螨亚科(Phyllocoptinae)丽瘿螨族(Calacarini).该螨为害后造成叶片畸形、变黄,严重影响茉莉的正常光合作用.茉莉丽瘿螨在中国为首次发现,目前仅发现发生在海南省茉莉上,建议采取必要的检疫措施和化学防治方法,防止该螨扩散.

Population occurrence of the fall armyworm,Spodoptera frugiperda(Lepidoptera: Noctuidae), in the winter season of China

Fall armyworm(FAW), Spodoptera frugiperda(J.E. Smith), has become an important pest in Chinese agricultural systems since its invasion on 11 December 2018. After its establishment, FAW months in the year-round breeding region have become the main source population migrating to other areas in China. Field investigations were conducted in tropical and subtropical regions to improve understanding of its year-round breeding area in China. The results showed that FAW larval density was significantly correlated with the seasonal temperature of the location surveyed. The FAW larvae maintained a high density in the tropical area and were frequently found in sites of the south subtropical region, but were absent from the north subtropical region and the northern part of the central subtropical region. These results indicated that FAW can reproduce annually in the tropical and south subtropical regions of China, including Hainan, Taiwan and the southern area of Fujian, Guangdong, Guangxi, Guizhou, and Yunnan. Hence, great effort should be made to monitor and control FAW in the year-round breeding region to suppress the population density of this area and to reduce migration of moths into northern parts of China. This study clarifies the occurrence area of the pest in winter in China and provides much valuable information for its population forecasting and management.
