胡瓜钝绥螨控制大棚甜椒烟粉虱的研究
Research and application of Neoseiulus cucumeris (Oudemans) for control of Bemisia tabaci (Gennadius) on sweet pepper in plastic greenhouse
摘要
Abstract
The study was conducted on vegetable base in plastic greenhouse of Shouguang, Shandong Province, China. The results showed that: ①. The predatory mite Neoseiulus cucumeris could prey on all stages of Bemisia tabaci (Gennadius) . The difference of developmental period of N. cucumeris feeding on prey among B. tabaci, Panonychuscitri ( (Mc Gregor) and Tetranychusurticae (Koch) at (25±1)℃、 (30±1)℃、 (35±1)℃ temperature, which is not significant. The fecundity of N. cucuneris feeding on all stage of whitefly is 10％-15％ lower than preying on spider mite P. citri or T. urtica; ②After the 30th, and 40th day from predator' s release the efficiency of N. cucumeris achieved 92.9％-93.6％, 61.12％-67.9％, respectively. Whereas the efficiency of chemical application obtained 30. 7 ％-50. 1％ and 55.1％-60.7 ％, respectively. ③Ten times of chemical application had been reduced in bio-control greenhouse compared with chemical application greenhouse. ④ Three times release of N. cucumeris were done during whole season (270 days) of sweet pepper, each time with predator 5 - 10 individuals per plant at seedling stage, 20-30 individuals per plant at fruiting stage.关键词
