白纹伊蚊对S-烯虫酯的抗药性评估

Resistance assessment of Aedes albopictus L. to s-methoprene

  • 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(h2),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h2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。

     

    Abstract:
    ObjectiveTo 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.
    MethodsThe resistance strain was developed by group selection, and the realized heritability (h2) of A.albopictus resistance to s-methoprene was estimated by Tabashnik′s method.
    ResultsThe resistance of A.albopictus to s-methoprene had increased by 11.93-fold after 15 generations of indoor breeding, and the h2 of A.albopictus to s-methoprene was 0.0234, indicating a relative risk of resistance development.
    ConclusionThe 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.
