| 摘 要： | 在自然变温条件下,研究了胡椒提取物对小菜蛾生物活性的影响.结果表明,胡椒提取物对小菜蛾3龄幼虫有显著的拒食作用和生长抑制作用,其非选择性拒食率和选择性拒食率分别为82.46%和85.29%,24 h和48 h的生长抑制率分别为86.60%和98.55%;胡椒提取物对小菜蛾成虫产卵也有明显抑制作用和很强的忌避作用,产卵量下降近60%.

| Abstract: | This paper deals with the effect of the crude extract from pepper on the Bio-activity of Plutellaxylostella under the natural temperature.The results showed that the extracts from pepper demonstrated most potent anti-feeding efficacy and inhibition to growth and development against 3rd larvae of Plutellaxylostella,the no choice anti-feeding rate and the choice anti-feeding rate were 82.46% and 85.29% respectively,24 h and 48 h of inhibitory rate were 86.60% and 98.55% respectively.It also has strong deterrent and inhibition to oviposition of adult,and the oviposition amount of adult decreased 60%. |
