摘  要：
通过室内毒力测定及田间药效试验评价氟啶虫胺腈原药以及22%氟啶虫胺腈悬浮剂和50%氟啶虫胺腈水分散粒剂对桃蚜和瓜蚜的杀虫活性。分别采用浸叶法和常规喷雾法进行室内毒力测定和田间药效试验。室内毒力测定结果表明,氟啶虫胺腈原药对桃蚜和瓜蚜48 h LC50值分别为0.98 mg/L和1.70 mg/L,氟啶虫胺腈对桃蚜和瓜蚜的相对毒力分别是啶虫脒的4.2倍和2.0倍。田间药效试验结果表明,22%氟啶虫胺腈悬浮剂和50%氟啶虫胺腈水分散粒剂对桃蚜和瓜蚜具有很好的速效性和持效性,平均防治效果为82.0%~96.0%。氟啶虫胺腈可有效防治桃蚜和瓜蚜,是农业生产上防治蚜虫的理想药剂之一。

摘  要：
To understand the insecticidal activity of sulfoxaflor and field performance of sulfoxaflor 22% SC and sulfoxaflor 50% WG against Myzus persicae and Aphis gossypii, laboratory bioassays were conducted by using leaf dipping method and field efficacy trials were carried out by method of foliar application. Laboratory bioassay results indicated that sulfoxaflor provided good insecticidal activity against M. persicae and A. gossypii and the LC50 values at 48 h were 0.98 mg/L and 1.70 mg/L, respectively. Sulfoxaflor showed effective potency to two species of aphids compared with acetamiprid with greater relative control of 4.2 and 2. Field efficacy results indicated that sulfoxaflor 22% SC and sulfoxaflor 50% WG provided quick knock down and relatively long residual efficacy on two species of aphids with average control of 82.0%-96.0%. Sulfoxaflor is one of the most effective molecules for control of aphids M. persicae and A. gossypii.
