前言应用磷化氢防治储藏物害虫(仓虫),已有四十余年的历史了,现在还是防治仓虫最重要的熏蒸剂。过去十几年,在使用磷化氢熏杀仓虫中,对用药量、防燃爆、残毒,种子发芽率、药效试验、以及对某些仓虫抗药性测定等方面的研究,考虑多一些;对磷化氢气体在粮堆内对不同虫种、虫态的最低致死浓度和磷化氢在粮堆中保持有效浓度的时间等研究报导不多;对熏蒸后不久又发现害虫,从仓虫生物学特性上去找杀虫不彻底的原因重视不够;而是比较强调某些仓虫种群对磷化氢的抗药力。
Preface The application of phosphine to control storage pests (caterpillars), has more than 40 years of history, and now is the most important prevention and treatment of caterpillars fumigation agents. Over the past ten years, the use of phosphine to kill cicadae insects, the dose, fire explosion, residual poison, seed germination rate, efficacy tests, and some of the insecticide resistance and other aspects of the study, consider more Some; for phosphine gas in the food piles for different species of insects, the lowest lethal concentration of insects and phosphine in the grain reactor to maintain an effective concentration of time reported little research; soon after the fumigation found pests, from The biological characteristics of the insects to find the insecticide is not thorough enough reason not enough attention; rather more emphasis on the resistance of some species of caterpillars phosphine resistance.
