用昆虫病原体使昆虫得病致死,达到防治害虫的目的,是近几年来的一项新研究。这么做,好处是明显的:1.昆虫病原体对于昆虫以外的生物是无害又无毒的,那么,就没有了余毒间题;2.昆虫病原体是专门对付某种昆虫的,于是对益虫就起了保护作用;3.许多昆虫病原体能够和杀虫剂相容,于是可以活物与药物并用;4.有些昆虫病原体既易生产且较便宜:5.和化学杀虫剂一般:6.寄主昆虫对昆虫病原体产生抵抗力显然很慢;7.可喷可撤用
Insect pathogens let insects get sick to achieve the purpose of pest control is a new study in recent years. In doing so, the benefits are obvious: 1. Entomological pathogens are harmless and non-toxic to organisms other than insects, and there is no problem with extraneous toxins. 2. Entomopathies are specialized for certain insects, Play a protective role; 3. Many insect pathogens can be insecticide compatible, so you can live with drugs; 4. Some insect pathogens easy to produce and cheaper: 5. And chemical insecticides in general: 6. Host Insects on the insect pathogen is obviously very slow resistance; 7 can be spray can be removed
