由于大量使用PH3杀虫,致使有些重要储粮害虫对它已产生了抗药性并日趋严重。为了解决这一问题,各国科学家均致力去研究用谷物保护剂来防治储粮害虫,取得了令人满意的效果。谷物保护剂是一种直接与粮食拌和以防治储粮害虫的物质。这物质可以是高效低毒化学杀虫剂(常规谷物保护剂),也可以是一些新型谷物保护剂:昆虫生长调节剂:硅藻土;源于自然的微生物制剂,以及一些杀虫机理与常规谷物保护剂一样的植物源杀虫剂。本文还对常规谷物保护剂防治储粮昆虫和螨美进行叙述。
Due to the extensive use of PH3 insecticide, some important stored grain pests have become resistant to it and worsening. In order to solve this problem, scientists from all countries have devoted themselves to studying the use of grain protectants to prevent and control grain pests and have achieved satisfactory results. Grain protectant is a substance that mixes directly with grain to prevent stored grain pests. This substance can be a highly effective and low toxic chemical insecticide (conventional cereal preservative) or some new grain protectant: insect growth regulators: diatomaceous earth; naturally occurring microbial agents, as well as some insecticidal mechanisms and conventions Plant protection insecticides. This article also describes the conventional grain protectants against stored grain insects and mites.
