针对柑桔高氏瘤粉虱严重为害福建省柑桔、茉莉花等多种作物的现象,在室内的温湿度条件饲养观察了其形态特征和生物学特性。结果:该虫为过渐变态类型,整个生活史可分为卵、若虫(3龄)、拟蛹、蛹和成虫。在28℃条件下,完成一个世代需要29~36d;25℃条件下,世代历期34~41d;20℃条件下,世代历期46~54d。在福州地区年可发生8~10代,以卵和若虫过冬,但越冬现象不明显,种群发生的高峰期为4~5月和9~10月。该虫具有严重的世代重叠现象。
In view of the phenomenon that Citrus gigantostereum whitefly seriously damages the crops of citrus and jasmine in Fujian Province, its morphological characteristics and biological characteristics are observed under the indoor temperature and humidity conditions. Results: The pest was an abnormal metamorphosis. The whole life history could be divided into eggs, nymphs (3rd instar), pupae, pupae and adults. Under the conditions of 28 ℃, it takes 29-36 days to complete one generation, 34-41 days of generation at 25 ℃, and 46-54 days of generation at 20 ℃. In Fuzhou area annual occurrence of 8 to 10 generations to egg and nymph winter, but overwintering phenomenon is not obvious, the peak of the population occurs from April to May and September to October. The worm has serious generations of overlap.
