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 degrees C) under laboratory conditions. Our results show that high temperatures (29, 32, and 35 degrees C) do not significantly affect lifetime host-killing events of female adults by increased daily host-killing events compared to temperature of 26 degrees C, 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.
