摘要:

对江西省十余个县(市)马尾松毛虫(Dendrolimus punctatus Walker)的测定表明,马尾松毛虫各种群对拟除虫菊酯的耐药力与羧酸酯酶活性有关;对溴氰菊酯、氰戊菊酯和氯氰菊酯耐药力强的种群,其羧酸酯酶活性亦强;应用五种增效剂对马尾松毛虫羧酸酯酶进行处理, SV1和TPP表现出明显的抑制作用,且随SV1和TPP剂量的增加,羧酸酯酶活性逐步降低;用相同剂量的SV1和TPP处理马尾松毛虫后,羧酸酯酶均随时间表现出相似的变化规律。

Abstract:

More than ten population of masson pine caterpillar (Dendrolimus punctatus Walker) in Jiangxi Province were tested by the methods of the bioassay and bioohemistry. The results showed that the tolerance to pyrethroids was related to the activity of carboxylesterase in masson pine carterpillar The activity of carboxylesterase was higher in population more tolerant to deltamethrin, fenvalerate and cypermethrin than in the population less tolerant. Treated carboxylesterase of masson pine carterpillar with five synergists, SV1, and TPP showed strongly inhibition, and as the amount of SV1 or TPP increased, the activity of carboxylesterase decreased correspondingly. After applying topically massonpine carterpillar with the same amount of SV1 or TPP, the activity of carboxylesterase changed regularly.
