4种植物源杀虫剂对扶桑绵粉蚧毒力及龟纹瓢虫安全评价
Toxicity of four botanical insecticides to Phenacoccus solenopsis and safety evaluation to predator Propylaea japonica
扶桑绵粉蚧 Phenacoccus solenopsis(半翅目：粉蚧科)最早于2008年6月传入中国广州，10多年间已扩散至中国18个省区，共记录有166种寄主植物，其中棉花受害最严重。化学防治和生物防治是该虫的重要防控手段。本研究旨在探索4种植物源农药对入侵害虫扶桑绵粉蚧的毒力，评价其对龟纹瓢虫卵及成虫的安全性，为扶桑绵粉蚧的绿色防控提供理想药剂和理论依据。采用喷雾法测定4种植物源杀虫剂对3龄扶桑绵粉蚧的毒力和龟纹瓢虫卵孵化率的影响，采用滤纸…查看全部>>
Phenacoccus solenopsis (Hemiptera: Pseudococcidae) was first introduced to Guangzhou, China in June 2008. It has spread to 18 provinces and regions in China in more than 10 years. A total of 166 host plants species of Phenacoccus solenopsis were recorded, among which cotton is the most severely affected.
