枸杞蓟马的发生及防治药剂研究

A Study of Occurrence and Chemical Control of Psilothrips indicus Bhatti

通过对枸杞蓟马形态特征、生活习性的观察和防治情况及田间虫口调查,发现随着农药品种的改变和防治方法的改进,枸杞蓟马在主产区已从次要害虫上升为主要害虫,造成的损失越来越大。为此,选择了符合出口枸杞生产的低毒无残留生物农药(艾绿士、习刀蓟马、云菊素、苦参素、吡虫啉)在试验基地进行防效对比研究,结果表明:5种生物农药对蓟马、蚜虫、木虱有很好的防治效果。建议群众可根据各农药的成本、持效期、枸杞产品质量安全要求选择,交替使用。

Based on the observation of the morphological characteristics and living habits of Psilothrips indicus Bhatti and an investigation of its control and field pest it was found that Psilothrips indicus Bhattin had became the primary pest in main production area in stead of secondary pests previously along with the change of pesticide varieties and improvement of the control approaches and the losses caused were increasing. For this reason, the low toxicity and no residue biological pesti- cides （AI Lvshi, Xidaojima, Yun Jusu, Oxymatrine and Imidacloprid ）in line with the requirements of the production of the Chinese wolfberry for export was selected to make control effect contrast researches at the experimental site. The ＂results showed that the effects of the abovementioned 5 biological pesticides on control of thrips, aphids and psylla were very good. It is suggested that the farmers can selected and use alternatively based on the cost and effective duration of the various pesticides as well as the quality and safety requirements of Chinese wolfberry products.
