杀虫剂的

The present invention also discloses the method of utilizing the strain in producing pesticide to kill several kinds of lepidoptera pests.

本发明还公开了该菌株制备杀虫剂的方法，该杀虫剂具有杀多种鳞翅目害虫的特点，扩大了苏云金芽孢杆菌杀虫剂的使用范围，降低农药防治费用、减少化学农药对环境的污染。

The federal statute regulating pesticides is called FIFRA, which stands for the Federal Insecticide, fungicide and Rodenticide Act

管理各种杀虫剂的联邦法令被称作FIFRA，是《联邦杀虫剂、杀菌剂与杀鼠剂法案》的字母缩写。

The single toxicity of Chlorpyrifos, Diazinon and Malathion and joint toxicity of ternary mixtures of organophosphate insecticides to photobacterium phosphoreum were determined.

实验测定了三种有机磷杀虫剂毒死蜱、二嗪农和马拉硫磷三种杀虫剂对发光菌的单一毒性，以及固定比率配比下三种有机磷杀虫剂的三元混合体系的联合毒性效应。

The lower dosage of commonly used insecticides mixed with Piperonyl Butoxide may have better control efficacy after the resistance of mosquitoes to insecticides was produced.

当淡色库蚊产生抗药性后，采用杀虫剂与氧化胡椒基丁醚混用的方法，可以减少杀虫剂的使用剂量，取得较好防治效果。

So unsusceptibility of 〓-ATPase to pyrethroid insecticide may be associated with pyrethroid resistance.

Na〓K〓-ATPase对拟除虫菊酯类杀虫剂的不敏感性是抗性家蝇品系对拟除虫菊酯杀虫剂产生抗性的机理之一。

NSE was showed to play important role in the mosquito resistance against organophosphorus insecticides and was one of important mechanism for the development of resistance towards carbamates, while it has little relation with the resistance against pyrethroids.

NSE在淡色库蚊对有机磷类杀虫剂的抗性中起重要作用，也是对氨基甲酸酯类杀虫剂产生抗性的机制之一，与对拟除虫菊酯类杀虫剂的抗性关系不大。

The AChE activity showed a correlation with the resistance of Cx.pipiens pallens to carbamates and organophosphorus insecticides,and little with that to pyrethroids.

AChE活性在淡色库蚊与氨基甲酸酯类及有机磷杀虫剂的生测抗性水平具有相关性，与拟除虫菊酯类杀虫剂的抗性关系不大。

Objective Study the indoor ground free flea control method to prevent occurrence and epidemic of mouse transmission diseases.

化学杀虫剂杀灭地面游离蚤，均以有机磷或拟除虫菊酯类杀虫剂的单一用药为主〔1，2〕，但在实际工作中发现，单一用药灭蚤效果很差。

Using a long-term reared housefly population which is very susceptible to pyrethroid insecticides as the susceptible strain, a population collected in 1993 in Shanghai and has been treaded by cyhalothrin as the resistant strain, we bioassayed their susceptibility to organophosphorus, carbamate, pyrethroid and organehloride insecticides. We also investigated the role of metabolic enzymes, i. e. esterase, GST, MFO and of target enzymes, i. e. AChE and 〓-ATPase in resistance to insecticides. Cyhalothrin resistance inheritance, the co-toxicity coefficient of cyhalothrin and methylene dithiocyanate was also studied. The insecticides resistance in adults and larvae of houseflies was compared and the mechanism of resistance differences between adults and larvae was discussed.

本文以采自野外并经过室内多代筛选的三氟氯氰菊酯抗性家蝇品系和室内多年饲养的敏感家蝇品系为试虫，测定了抗性家蝇品系和敏感家蝇品系对拟除虫菊酯杀虫剂三氟氯氰菊酯、氯菊酯、有机磷杀虫剂DDVP、氨基甲酸酯杀虫剂残杀威、有机氧杀虫剂DDT的抗性水平，并通过活体增效剂实验和离体生化实验研究了抗性品系的解毒酶和靶标酶的变化，本文还研究了三氟氯氰菊酯和增效剂I对抗性家蝇的增效作用及增效机理、家蝇幼虫和成虫对杀虫剂的抗性差异及其抗性差异的机理。

The paper discusses the present research and application of microbial insecticides and their prospect in China.

阐述了微生物杀虫剂研究开发的意义、杀虫机理、国内微生物杀虫剂的研究应用现状及其发展前景。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
