二斑叶螨抗性种群对6种杀螨剂的敏感性测定
Sensibility Testing of Resistant Populations of Tetranychus urticae to Six Acaricides
摘要
Abstract
The sensibility of Tetranychus urticae Koch in greenhouses from Changle County (R1 ) and Shouguang City ( R2) to six acaricides was evaluated by slide - dip method. The results revealed that fenproxi-mate had the highest toxicity to adults of the two populations with the LC50 as 2. 384 mg/L (R1) and 1. 939 mg/L (R2) respectively. The followed one was abamectin, whose LC50 was 2. 426 mg/L ( R1 ) and 9. 921 mg/L (R2) respectively. In the R1 population, the LC50 of emamectin benzoate, chlorfenapyr and hexythiazox was in the range of 34.383 to 1 237. 592 mg/L, and their relative toxicity were 82.499, 9. 808 and 2. 292 times of that of pyridaben respectively. Hexythiazox ( LC50 = 1 225. 602 mg/L) had the lowest toxicity in R2 population, and the relative toxicity of chlorfenapyr ( LC50 =791. 649 mg/L), pyridaben ( LC50 = 308.580 mg/L) and emamectin benzoate ( LC50 = 13. 892 mg/L) was 1.548 - 88.223 times of its.关键词
