【摘要】 选用10个黄瓜品种通过选择性和非选择性试验,探讨烟粉虱对黄瓜品种的选择性。结果表明,烟粉虱成虫对不同黄瓜品种取食和产卵的选择存在一定差异,最喜好中农19号、裕优3号及22-35RZ,最不喜好四季秋瓜、22-94RZ、春光2号。烟粉虱在不同黄瓜品种上的卵孵化率、羽化率没有显著差异,均能正常发育。黄瓜品种叶毛密度与烟粉虱成虫趋向和产卵量存在显著正相关。更多还原

【Abstract】 The effects of ten cucumber varieties on the feeding and oviposition of adult Bemisia tabaci were assessed using selection and non-selection tests.The results showed that the quantity of adults and eggs per plant on Zhongnong NO.19,Yuyou NO.3 and 22-35RZ were significantly higher than that on Sijiqiugua,22-94RZ and Chunguang NO.2.There was no significant difference in the hatch rate and emergency rate among the cucumber varieties,and all the pests developed normally.The density of the leaf hairs of different cucumber varieties demonstrated significantly positive correlation with the adult preference and oviposition.更多还原
