摘　　要：Temperature, as a critical abiotic factor, might influence the effectiveness of biological control by parasitoids in hostparasitoid systems. In this study, Neochrysocharis formosa(Westwood), a larval endoparasitoid, is used to investigate the efficacy of biological control on a vegetable agriculture pest, Liriomyza sativae Blanchard, reared on kidney bean(Phaseolus vulgaris L.), at four constant temperatures(26, 29, 32, and 35℃) under laboratory conditions. Our results show that high temperatures(29, 32, and 35℃) do not significantly affect lifetime host-killing events of female adults by increased daily host-killing events compared to temperature of 26℃, although their lifespans decrease with an increase in temperatures. Each life-history trait of female adults(lifespan, parasitism, stinging, or non-reproductive host-killing events) present a linear relation with temperatures and host-feeding events, respectively. Our findings contribute to a better understanding of biocontrol efficacy of parasitoid N. formosa against agromyzid leafminers at high-temperature seasons or environments.
