| Abstract: | 【Objective】 To evaluate the insecticidal activity of chlorfenapyr, flupirfuranone, nitenpyram, 22% flupirfenapyr SC, 17% flupirfuranone SC and 5% nitenpyram against cotton Aphis gossypii by indoor toxicity test and field efficacy test. 【Methods】 indoor toxicity test and field efficacy test were conducted by leaf dipping method and stem leaf spray method respectively. 【Results】 The results of indoor toxicity test showed that the 24 h LC50 of fipronil flupyrfuranone and nitenpyram to Aphis gossypii were 2.41, 1.49 and 0.81 μg/mL respectively, and the 48 h LC50 were 1.35, 0.72 and 0.32 μg/mL respectively. The results of field trials showed that 22% fipronil SC and 7% flupyrfuranone SC had good quick effect on Aphis gossypii, and the average control effect was more than 70%. 【Conclusion】 Fipronil, flupyrfuranone and nitenpyram can effectively control Aphis gossypii, and they are ideal substitutes for high toxic pesticides to control Aphis gossypii in cotton production. |
