杀虫谱

甲基异柳磷（Isofenphos-methyl）是一种杀虫谱广，残效期较长的新型杀虫剂。

Isofenphos-methyl is a new type of insecticides , broad spectrum insecticide , residues longer valid .

对Wilfordine、Wilforine的杀虫谱进行了研究。

The insecticidal scope of wilfordine and wilforine were studied .

两者在功能（例如杀虫谱）方面有何差别？

Are there any difference ( such as insecticidal spectrum ) between them ?

但是野生型杆状病毒用作杀虫剂也存在很多不足之处，如杀虫谱窄、杀虫速度慢等缺点。

However , it has some disadvantages . For example , low speed of killing and narrow insecticidal spectrum .

本品活性高、低残留、速度快、击倒力强、杀虫谱广。

OriginallyArticle activity Gao , low remain , speed quick , knock down dint strong , Destroy insects a table wide .

然而根据研究得知，野生型杆状病毒具有杀虫谱窄，杀虫速度慢的缺点。

But wild type baculoviruses have a narrow spectrum hosts and slowly killing speed according to the studies of their infecting processes in cells or in insects .

阐述了δ-内毒素受体的性质，并且着重从受体角度，阐述了δ&内毒素杀虫谱差异的分子基础及其杀虫机理。

It describes the nature of the recepter , and emphatically describes the molecular basis and the mechanism of the difference in the insecticidal spectrum of δ - endotoxin .
