除虫

It may cause acute and chronic neurotoxicity to mammal,and the stereoisomeric structure of SPs affects mammals neurotixicity.

拟除虫菊酯类农药是目前使用广泛的一类神经毒性杀虫剂，主要用于农业和卫生害虫的防治。

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。

It is also important to begin a worming regimen from the age of one month as foals are susceptible to worms picked up via their mother's milk and from grazing.

因为小马驹容易通过他们母亲的乳汁以及放牧感染寄生虫，所以从一个月大的时候开始一项除虫制度是非常重要的。

Even if dumping weedkiller on the crops of peasant farmers quadruples the local price of coca leaves, this tends to have little impact on the street price, which is set mainly by the risk of getting cocaine into Europe or the United States.

尽管对这些作物喷洒除虫剂而使得当地可卡树叶的价格翻了四倍，但是这对街头卖出价却影响甚微，卖出价主要是由将可卡因提供到欧洲和美国的风险风险所决定的

As a result, thousands of volunteers are constantly working on Linux, adding new features and winkling out bugs.

结果，成千上万的自愿者不断地研究linux，为它增加新的特色并除虫纠错。

Objective: To examine the feasibility of different extraction methods for the simultaneous determination of 7 kinds of pyrethroid pesticide multiresidues in dringking water by capillary gas chromatography.

目的：考查采用不同萃取方法及毛细管气相色谱法同时测定饮用水中多种拟除虫菊酯类农药残留量的可行性。

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。

A GC-MS/MS method was developed for the simultaneous determination of 50 pesticides residues,including 38 organophosphorus pesticides,7 N-methy1 carbamates and 5 pryethoids insecticides,whose molecular weights ranged from 185 to 503,in vegetable.

建立了气相色谱-串联质谱同时检测蔬菜中50种(38种有机磷、7种有机氮和5种拟除虫菊酯类)农药的多残留分析方法。

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。

Pyrethroids used in mixture with Organophosphates or Carbamates could effectively control insecticide resistance mosquito.

结论当淡色库蚊产生抗药性后，采用有机磷或氨基甲酸酯类杀虫剂与拟除虫菊酯类混用的方法，能取得较好效果。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
