新疆一枝蒿与黄花蒿粗提物抗棉铃虫与棉蚜的特性研究
The Study on Resistance of Artemisia rupestris and Artemisia annua to Cotton Bollworm ( Helicoverpa armigera ) and Cotton Aphid ( Aphis gossypii )
摘要
Abstract
[ Objective] This research can be a foundation for the development of new pollution - free botanical insecticides. [Method] Two types of coarse solutions from Artemisia rupestris and Artemisia annua were extracted with 97％ ethanol, and toxicities of the two extracts to cotton bollworm and cotton aphid were determined, and expellent effect of Artemisia rupestris to laying eggs of cotton bollworms in both the laboratory and the field were also studied. [Result] The results showed: (1) The LC50 of extracts from Artemisia rupestris and Artemisia annua to cotton bollworm are 0 .956 and 2.047 4 g/1OOmL; (2) The LC50 of extracts from Artemisia rupestris and Artemisia annua to cotton aphid are 0.956 and 2.047 4 g/1OOmL; (3) The repellency of extracts of Artemisia rupestris on laying eggs of cotton bollworm in the laboratory and in the field are 28.39％ and 80. 68％ . [Conclusion] The findings demonstrate that the extracting coarse solutions from Artemisia rupestris are better than that from Artemisia annua as to the killing effect on cotton bollworm and cotton aphid, and it had an expellent effect on laying eggs of cotton bollworms in both the laboratory and the field .关键词
