The prophylactic application of synthetic insecticides to manage (Bagrall) has resulted in insecticide resistance and negative impacts upon natural ecosystems. This has driven the need for developing alternative pest control strategies. In the present study, we investigated the synergistic interaction between the entomopathogenic fungus and the insecticide emamectin benzoate on . The results of our research exhibited that higher doses of emamectin benzoate inhibited the germination rate and colony growth of . The percentage of mortality following and emamectin benzoate treatment indicated a dose-mortality effect. All concentrations of emamectin benzoate combined with different concentrations of demonstrated a synergistic effect five days post-treatment. When and emamectin benzoate were applied alone or in combination, antioxidant enzyme activities, including acetylcholinesterase, catalase, superoxide dismutase, and peroxidase, were significantly lower in than in the controls at the end of the experimental period. The findings of our study confirm the synergistic effect of and emamectin benzoate on , as well as the biochemical process that might be involved in the regulation of the synergistic effect.
合成杀虫剂的预防性应用来防治（某种害虫，原文Bagrall有误）已导致了抗药性以及对自然生态系统的负面影响。这推动了开发替代害虫控制策略的需求。在本研究中，我们调查了昆虫病原真菌与杀虫剂甲氨基阿维菌素苯甲酸盐对（某种害虫，原文表述有误）的协同相互作用。我们的研究结果表明，较高剂量的甲氨基阿维菌素苯甲酸盐会抑制（某种真菌，原文表述有误）的萌发率和菌落生长。（某种害虫，原文表述有误）经（某种真菌，原文表述有误）和甲氨基阿维菌素苯甲酸盐处理后的死亡率呈现出剂量 - 死亡率效应。在处理五天后，所有浓度的甲氨基阿维菌素苯甲酸盐与不同浓度的（某种真菌，原文表述有误）组合均表现出协同效应。当单独或联合施用（某种真菌，原文表述有误）和甲氨基阿维菌素苯甲酸盐时，在实验期结束时，（某种害虫，原文表述有误）体内的抗氧化酶活性，包括乙酰胆碱酯酶、过氧化氢酶、超氧化物歧化酶和过氧化物酶，均显著低于对照组。我们的研究结果证实了（某种真菌，原文表述有误）和甲氨基阿维菌素苯甲酸盐对（某种害虫，原文表述有误）的协同效应，以及可能参与协同效应调节的生化过程。
