摘　　要：【目的】评估白纹伊蚊对S-烯虫酯的抗药性风险,预测抗药性发展速率,为药物的科学合理使用提供科学依据。【方法】通过室内抗性选育方法获得用于抗性风险评估的品系,利用数量遗传学的原理和方法估算抗性现实遗传力(h 2),通过运用抗性现实遗传力预测白纹伊蚊对S-烯虫酯的抗性发展速率。【结果】经过15代的室内选育,白纹伊蚊对S-烯虫酯的抗药性倍数上升了11.93倍;白纹伊蚊对S-烯虫酯的抗性h 2为0.0234,有一定抗性风险。【结论】白纹伊蚊对S-烯虫酯有一定抗性风险,应根据实际情况科学合理使用杀虫剂。[Objective]To assess the risk of s-methoprene resistance development in Aedes albopictus L.(A.albopictus)and predict the rate of resistance development,providing the reference for scientific and rational application of insecticides.[Methods]The resistance strain was developed by group selection,and the realized heritability(h 2)of A.albopictus resistance to s-methoprene was estimated by Tabashnik′s method.[Results]The resistance of A.albopictus to s-methoprene had increased by 11.93-fold after 15 generations of indoor breeding,and the h 2 of A.albopictus to s-methoprene was 0.0234,indicating a relative risk of resistance development.[Conclusion]The results indicate that A.albopictus has resistance risk to s-methoprene,so attention should be paid to proper use of insecticides based on the situation of targeted pest.
