摘要：Recently, Apolygus lucorum (Hemiptera: Miridae) has become an important insect pest of Bt cotton and fruit trees in China. At present, the application of chemical insecticides is the main control option for this pest. We investigated the lethal effect of seven neonicotinoid insecticides on A. lucorum adults, including six commercialized neonicotinoids and a novel one, cycloxaprid, which is developed in China. In addition, we assessed the sublethal physiological (longevity, fecundity) and behavioral (preoviposition and oviposition periods) effects of LD10 (low lethal dose) and LD40 (moderate lethal dose) of cycloxaprid on the mirid bug. Lethal effect of the insecticides was determined using a topical exposure method; contact toxicity against the adults was ranked as follows: cycloxaprid, nitenpyram > clothianidin > acetamiprid, imidacloprid > thiamethoxam > dinotefuran. Among these insecticides, the toxicity of cycloxaprid against the adults was the highest; its LD50 value was 2.54 ng a.i .(active ingredient)/adult. Both LD10 (0.74 ng a. i./adult) and LD40 (1.98 ng a. i./ adult) of cycloxaprid induced sublethal effects in the adults; we observed a reduced longevity in males and the LD40 also shortened the longevity of females. In addition, the LD40 prolonged the pre-oviposition period and shortened the oviposition period of females, and it decreased their fecundity. The hatching rate of eggs laid by the females exposed to LD10 and LD40 greatly decreased (two-fold lower when exposed to LD40). Our results demonstrate that cycloxaprid is among the best candidate insecticides for controlling A. lucorum, and it showed significant lethal and sublethal effects on this mirid bug.
