几种非十字花科蔬菜提取物对菜青虫的干扰控制作用

摘要: 研究了9 种非十字花科蔬菜乙醇提取物对菜青虫种群的干扰控制作用。结果表明, 9 种非十字花科蔬菜提取物对菜青虫成虫产卵都有较好的忌避作用, 但对卵和低龄幼虫的毒杀作用不明显。其中茼蒿、大蒜和番茄对菜青虫种群的干扰控制作用较好, 干扰作用控制指数分别达到0.0965、0.1166和0.0557, 即控制效果分别达到90.35%、88.34%和94.43%。

The Interference Control Effects of Several Non-crucifer Vegetable Extracts on Artogeia rapae

Abstract:Based on the co-evolution between chemical defence of plant and behavior of phytophgous insects, the interference control effects of alcohol extracts of nine kinds of non-crucifer vegetables on Artogeia rapae were studied in this paper. The results showed that the extracts of the nine non-crucifer vegetables had significant effects of repelling adults and deterring egg laying, but had no evident effects of causing death by toxicity on egg and small larva of Artogeia rapae. Among the non-crucifer vegetables, crowndaisy chrysanthemum, garlic and tomato had the most significant control effects on the population of Artogeia rapae and their interference indices of population control（IIPC） were0.0965、0.1166 and0.0557 respectively. It meant that their control effects reached 90.35%、88.34% and 94.43% respectively.
