英文摘要	Both neonicotinoids and pymetrozine are important insecticides and may have the potential to be used in combination with natural enemies in integrated pest management (IPM). However, to determine their compatibility with biological control, it is necessary to examine the side effects of these chemicals on natural enemies. We examined the acute and sublethal effects of four commonly used neonicotinoid insecticides, imidacloprid, dinotefuran, nitenpyram and thiamethoxam, and the pyridine azomethine, pymetrozine, on adults of Trichogramma ostriniae. By analysing acute toxicity and evaluating the safety quotient of these chemicals, we found that thiamethoxam and dinotefuran pose extremely high risks to T. ostriniae, imidacloprid and nitenpyram posed high risks, but pymetrozine was found to have a low risk. In terms of sublethal effects, longevities of female wasps were significantly shortened when they were exposed to residues of dinotefuran. Percentages of ovipositing females decreased significantly after exposure to pymetrozine, thiamethoxam and dinotefuran. Numbers of offspring per female were significantly lower when females were exposed to pymetrozine, dinotefuran or thiamethoxam, compared with control females. Percentages of offspring that emerged as adults were lower when parental females were exposed to either pymetrozine or imidacloprid. Based on the results of the sublethal concentration assay and the acute toxicity bioassay, nitenpyram would be safe for IPM programmes utilising T. ostriniae, and we suggest that T. ostriniae could be released safely after foliar applications of nitenpyram. However, foliar application of imidacloprid, thiamethoxam, dinotefuran or pymetrozine in an agro-ecosystem where T. ostriniae is a predominant biocontrol agent should be carefully evaluated.
