| 摘 要： | 研究了4种豆科寄主植物及5个不同温度处理对西花蓟马生长发育的影响,并对各虫态的发育起点温度和有效积温进行了分析。结果表明:同一温度条件下,西花蓟马取食不同豆科寄主植物时,各虫态的发育历期差异显著,但不同温度下不同寄主处理间的差异性不同;西花蓟马的未成熟期取食四季豆叶片时发育最快,取食蚕豆叶片时发育最慢,两寄主间存在显著差异;取食同一寄主植物时,不同温度处理下,西花蓟马各虫态的发育历期差异显著,且随温度升高历期缩短,发育速率和温度之间为直线关系;西花蓟马各虫态在不同寄主植物上的发育起点温度和有效积温各不相同,未成熟期取食蚕豆叶片时发育起点温度最低为6.35℃,但需要的有效积温最高为331.36日度。

| Abstract: | In this study,different concentrations of methyl salicylate(MeSA)were sprayed on the tea plants in a nuisance-free tea garden,and yellow sticky trap was used to investigate the population densities of pests and their natural enemies.No significant effect was observed after 24 h MeSA treatment.However,after 48 h,there was a significant decline in the number of tea green leafhopper and a significant increase in the number of ladybug,spider,syrphid,and parasitoids,as compared with the control,which indicated t... |
