药剂防治地下害虫(蝼蛄、蛴螬等)在综合防治措施中占有重要地位,研究取代高残留和剧毒农药,是农业生产上迫切需要解决的问题。几年来共研究测定了数十种药剂对地下害虫的防治效果。本文只介绍地亚农的试验结果。地亚农由于毒性较低(对鼠口服致死中量108毫克/公斤),用于防治地下害虫效果也较好,很受重视。试验所用的50％地亚农乳剂,系山东张店农药厂提供。在室内,我们用地亚农对华北蝼蛄(Gryllotalpa unispina saussure)进行毒力测定,其胃毒作用较强,对华北蝼蛄成虫的胃毒致死中量(LD_(50))为1.21微克/克,触杀致死中量为5.25微克/克,由此说明,地亚农对蝼蛄有相
Prevention and control of pesticides Underground pests (蝼 蛄, 蛴 螬, etc.) occupy an important position in comprehensive prevention and control measures. Studying instead of high-residue and highly toxic pesticides is an urgent problem to be solved in agricultural production. Over the past few years to study the determination of dozens of agents on the prevention and treatment of underground pests. This article only introduces the test results of Diane. Due to its low toxicity (oral dose of 108 mg / kg), Diazong is very effective in preventing and controlling underground pests and is highly valued. 50% of the pesticide used in the trial was supplied by Shandong Zhangdian Pesticide Factory. Indoors, we used Asian farmer to test the virulence of Gryllotalpa unispina saussure, which had strong stomach toxicity and a lethal dose (LD 50) of 1.21 μg / Lethal amount of 5.25 micrograms / gram, which shows that the Asian farmers on the 蝼 蛄 phase
