Abstract

A fenvalerate-resistant strain of Amblyseius pseudolongispinosus Xin, Liang & Ke was selected and evaluated for level of resistance. After 18 selection cycles, the LC₅₀ value was 65 times higher than in wild-type strain. Resistance was partially lost if the selection pressure was removed. Genetic studies indicated that the resistance factor was controlled by a single, incompletely dominant gene. The resistant strain, which had the same intrinsic rate of increase as the wild-type strain, might be a useful biological control agent of spider mites in an IPM system.
