摘要
为探索联苯肼酯对土耳其斯坦叶螨的亚致死效应,在试验室恒温条件下,使用种群生命表技术,探讨了亚致死浓度(LC_(10)、LC_(20))的联苯肼酯对其成螨与卵种群生长发育及生命表相关参数之间的影响。结果表明,与清水对照相比,成螨通过联苯肼酯(LC_(10)、LC_(20))处理后,平均产卵量、平均寿命和次代卵孵化率下降了48.69%~54.39%、40.32%~44.32%和5.75%~15.79%;其次代种群中,幼螨期、卵期(均为LC_(20))和若螨期(LC_(10))明显延长,而产卵前期(LC_(10))、雌螨寿命与成螨期明显缩短;卵通过处理后,若螨期、幼螨期(均为LC_(20))、雌螨寿命与成螨期明显缩短。与CK相比,所有联苯肼酯处理下,成螨和卵次代种群中T、(平均世代周期)Ro(种群净生殖率)、平均每雌日产雌数与存活率均明显下降,而rm(种群内禀增长率)有所上升。综上所述,施用亚致死浓度的联苯肼酯为制定综合防治土耳其斯坦叶螨策略提供了有益的启示,使其种群的发育速度延缓。
To explore the sublethal effects of bifenazate on Tetranychus turkestani,the study was conducted under controlled laboratory conditions using population life table technology to investigate the effects of sublethal concentrations(LC_(10),LC_(20))of bifenazate on the growth and development of adult mites and eggs,as well as life table parameters.The results showed that compared to the control,the adult mites treated with bifenazate(LC_(10),LC_(20))had a 48.69%-54.39%decrease in average egg production,a 40.32%-44.32%decrease in mean longevity,and a 5.75%-15.79%decrease in egg hatchability.In the next generation,the larva stage,the egg stage(all LC_(20)),and the nymPh stage(LC_(10))were significantly prolonged,while the pre-oviposition adult(LC_(10)),the longevity of female mites and the adult stage were significantly shortened.For the eggs,the nymPh stage,the larval stage(all LC_(20)),the longevity of female mites,and the adult stage were significantly shortened after treatment.Compared with the control,all bifenazate treatments significantly decreased the values of T and Ro,the average number of offspring per female per day,and the survival rate in the adult and egg next-generation populations,while the value of rm increased.In conclusion,the application of sublethal concentration of bifenazate provides valuable insights for developing integrated pest management strategy for T.turkestani,as it delays the development rate of its population.
