现行稻田主推农药对家蚕毒性试验的研究

Research about noxious influence of the main pesticides used currently in paddy fields on Bombyx mori

当前,在稻桑混栽局部区域,害虫多种并发,且抗性增加,导致用药种类多、剂量大、次数多,对秋蚕安全生产构成严重威胁。为充分掌握现行稻田农药品种的特性,准确了解对家蚕饲养的毒性影响,做到提前预防中毒,规避饲养风险,特组织开展了本试验研究。通过针对性的研究,对6种农药的残毒药效、中毒表现、影响程度等有了基本了解,便于以后合理使用农药,谨慎操作。

At present, in some part of the region where rice and Sericultureg are reard mixedly, there are many kinds of destructive insects coincidence and their resistance increases, which leads to more kinds of pesticides, big dosage and more frequence, and all these are very dangerous to the salty production of silkworm in autumn. In order to master the characteristics of the pesticides used in paddy fileds currently, and exactly understand the noxious influence on the breed of bombyx mori ; make to preventing from intoxation in advance and avoiding the breeding risk, we carry out this research especially. Through direct investigation, we have had an fundamental understand about the appearance of the residual toxicity, the feature of intoxation and the degree of hazard,in that case we can rationally use pesticide, and perform carefully.
