摘 要: | [目的]确定春季桃树蚜虫的防治适期及筛选出高效低毒药剂,为生产上推广应用提供理论依据。[方法]连续2 a调查春季桃树蚜虫的田间发生规律以及几种药剂在田间的防治效果。[结果]2014和2015年春季蚜虫发生高峰期分别为5月15日和5月10日,2015年蚜虫发生数量明显比2014年大。药后7 d,田间药效试验中各药剂的防治效果从大到小依次为46%氟啶虫酰胺·啶虫脒、50%氟啶虫胺腈、5%啶虫脒、25%吡蚜酮、40%毒死蜱、25%吡虫啉。[结论]春季桃树蚜虫的防治适期在5月10日之前,防治桃树蚜虫最适药剂为46%氟啶虫酰胺·啶虫脒,50%氟啶虫胺腈及5%啶虫脒可交替使用。

Occurrence and Control of Spring Peach Aphid |

Abstract: | Objective] To study the optimal control stage of spring peach aphid,to select high-efficient and low-toxicity medicament,and to pro-vide the basis for popularization and application in production. [Method] For consecutive two years,we investigated the occurred law of spring peach aphids in the field and the control effect of several kinds of agents in the field. [Result] The peak periods of the occurrence of spring peak aphids were May 15,2014 and May 10,2015. The number of aphids in 2015 occurred significantly more than the number in 2014. After drug ap-plication for 7 d,control effects in field efficacy tests were in the order of 46% flonicamid·acetamiprid > 50% sulfoxaflor > 5% acetamiprid> 25% pymetrozine > 40% chlorpyrifos > 25% imidacloprid. [ Conclusion] The optimal control period for spring peach aphid should be be-fore May 10. The optimal reagent for the control of spring peach aphid is alternate use of 46% flonicamid·acetamiprid,50% sulfoxaflor and 5%acetamiprid. |
