利用磷化氢防治仓库害虫,虽然大约已有四十年的历史,但目前仍然是人类除治贮藏害虫的最重要手段之一.其所以能够长期持续地被人们所采用,无疑是由于现在还没有发现具有更多优越性可以取代的新品种.从现有报导看来,这种可能性在近期内仍然不大.然而,对于这种具有许多独特优点的杀虫气体,大约在出现以后二十多年里,有关毒性和毒理方面的研究进展较慢;大部份的报导长期停留在应用上的药效测定.只是近十年来,在害虫对其产生抗性的实例日益增多和人们在食品卫生要求日益严格的情况下,方引起较多的重视,相应开展了较多的研究工作.若干较有远见的科学工作者,
The use of phosphine to prevent and control warehouse pests, although about 40 years old, is still one of the most important means for mankind to save pests and, therefore, it can be used by people for a long time, no doubt because now No new species with more superiority can be found, which has not been available in the near future, according to reports available.However, with this unique insecticidal gas with many unique advantages, For more than a decade, research on toxicity and toxicology has progressed slowly, with most reporting on long-term pharmacodynamic efficacy. Only in the last decade has seen an increasing number of instances of pest resistance In the increasingly stringent food hygiene requirements, the side attracted more attention, the corresponding more research work carried out.A number of more forward-thinking scientists,
