吡丙醚在生姜贮存期防治姜异型眼蕈蚊幼虫的可行性及安全性研究

Feasibility and Safety Study on Pyriproxyfen Against Phyxia scabiei Hopk Larvae for Ginger Storage

本研究利用吡丙醚贮存生姜,研究其对生姜贮藏期害虫的防治效果及安全性。制备了施用安全且方便的新制剂吡丙醚1%粉剂,测定了吡丙醚对姜异型眼蕈蚊3龄幼虫的毒力,测定了吡丙醚1%粉剂对生姜不同品种发芽及株高的影响,利用气相色谱-质谱法检测了生姜中的吡丙醚残留量。结果表明吡丙醚对生姜贮存期姜异型眼蕈蚊幼虫有较好的防治效果,且对生姜无不利影响,可以作为生姜贮存期防治姜异型眼蕈蚊幼虫的药剂。

This study was conducted by storing gingersunder the protection of pyriproxyfen, and aimed to determine the control efficacy and safety of pyriproxyfen duringgingerstorage period. A new formulation, pyriproxyfen 1% powder with safe and convenient application, was developed.The toxicity of pyriproxyfen to the third instar larvae of pnyxia scabiei Hopk was tested, as well as the effect of pyriproxyfen on the germination and plant height of the different varieties of gingers. The pyriproxyfen residue in ginger was determinedby gas chromatography-mass spectrometry. The results showed that pyriproxyfen had a very good control to Pnyxia scabiei Hopklarvae,and was very safe to gingers. Therefore, pyriproxyfen could be used to control Pnyxia scabiei Hopk larvae for gingerstorage.
