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.
