摘要
以早春红玉西瓜和风味五号甜瓜为材料,采用25%噻虫嗪分散粒剂2 000倍液苗期灌根,辅助纱网阻隔、色板诱虫的综合防治措施,研究了综合防治对设施栽培西瓜、甜瓜田间主要害虫种类及其发生动态的影响。结果表明:西瓜、甜瓜设施栽培主要害虫为烟粉虱、瓜蚜、朱砂叶螨和蓟马,秋茬害虫发生量高于春茬,且植株生长后期比前期严重;采取综合防治方法能够显著降低田间烟粉虱、瓜蚜和朱砂叶螨的发生量,有较好的防治效果。
The watermelon variety “Zaochunhongyu” and the melon variety “Fengwei No.5” were taken as material and the comprehensive control measures that irrigating 2 000-fold of 25% thiamethoxam liquid to the roots at seedling stage and assisting with gauze and color board were adopted to study influence of comprehensive control on main pest species and their occurrence dynamic in field with protected cultivation of watermelon and melon. The results showed that the main pests for protected cultivation of watermelon and melon mainly were Bemisia tabaci, Aphis gossypii Glover, Tetranychus cinnabarinus and Thrip; the amount of pests occurred in autumn was higher than that occurred in spring, and the insect pests were more serious in late growth stage in comparison with early growth stage; using comprehensive control measures can significantly reduce the number of Bemisia tabaci, Aphis gossypii Glover and Tetranychus cinnaharinus occurred in field. Therefore, the comprehensive control measures had good control effect.
