Abstract:【Aim】 The main goal was to screen highly efficient and low-risk insecticides for controlling Tuta absoluta. 【Method】 A total of nine insecticides based on insect growth regulators were selected for toxicity and field efficacy testing. Indoor toxicity of nine insecticides and their control effects after field spraying were determined. 【Result】 The results of indoor toxicity showed that 10.5% emamectin benzoate SC had the highest toxicity, with the LC50 value at 48 h was 0.061 mg·L-1. Moreover, 10% tetrachlorantraniliprole SC also exhibited good insecticidal activity, with an LC50 value of 0.064 mg·L-1. The order of toxicity of the nine insecticides to tomato leaf miner moth: 10.5% emamectin benzoate SC>10% tetrachlorantraniliprole SC>5% hexaflumuron EC>30% cyromazine SC>25% chlorbenzuron SC>50000 IU/mg Bt-G033A WP>20% tebufenozide SC>22% metaflumizone SC>50% chlorfluazuron EC. The results of field control showed that the control effect ranged from 16.67% to 85.33%, 3 d to 14 d after application. Among them, treatment with 30% cyromazine SC treatment demonstrated fast effect, prolonged duration, and effective control. The field control effect could be maintained at 65.00% 14 d after application, which was higher than that of other pesticides (P<0.05). This was followed by 25% chlorbenzuron SC and 20% tebufenozide SC, with the field control effect for 30% cyromazine SC remained at 60% 14 d after application, which was higher than other agents (P<0.05). 【Conclusion】 In conclusion, 30% cyromazine SC, 25% chlorbenzuron SC, and 20% tebufenozide SC were identified as the most suitable pesticides for controlling T. absoluta.
