【摘要】 根据植物精油在抗菌、杀虫和杀螨等方面的研究,考虑其无污染、无残留、用量少、价格低以及可阻止或延缓螨类的抗药性的特点,我们采用药膜法,进行了百里酚对刺足根螨[Rhizoglyphus echinopus(Fumouze&Rob in)]的毒力实验。结果表明,24 h的LC50=2.2222 g.L-1;48 h的LC50=0.6086 g.L-1。该实验为植物油应用于害螨防治提供了参考。更多还原

【Abstract】 Considering essential oils having antifungal and pests killing activity,less residue,lower price and being uneasy to develop resistance to mites,we conducted an experiment on the toxicity of thymol to Rhizoglyphus echinopus（Fumouze et Robin）.The residual film method was applied.The result indicated that LC₅₀=（2.2222）(g·L^-1) after 24 hours and LC₅₀=0.6086 g·L^-1 after 48 hours.This experiment would provide some insight into the application for the usage of essential oil in prevention and control of rhizoglyphid mites.更多还原
