You might not remember us, but we are the girls that fogged you.

嗨！你也许忘了，上次喷你杀虫剂的是我们俩。

Danny: I had to cut my hair to get rid of the uh, fogger smell.

不， Danny ？我不得不剪掉头发，杀虫剂的味道太浓。

There are no records of rodenticide application, and existing pesticide use records are

没有灭鼠剂的使用记录，没有对现有的杀虫剂使用记录定期分析以证明杀虫剂的用量在持

The survey about employing insecticide in zone of releasing Aphidius gifuensis and convention field show that: Agricultural chemicals employment number of times reduce 1.22 and average employment amount reduced 40%.

对放蜂区和常规施药防治区内烟农施用杀虫剂情况的调查表明，在放蜂区施用杀虫剂的平均次数为1.83次，而常规施药防治区为3.05次，放蜂区的施药次数比常规防治区减少40%。

In order to find screening rules suitable for lead compounds of pesticide,five descriptors:logarithm of partition coefficient of octanol/water,relative molar weight,number of hydrogen-bond donors,number of hydrogen-bond acceptors,polar surface areaand carcinogenic and mutagenic toxicities of 242 fungicides,512 herbicides and 399 insecticides were calculated and analyzed.

为了寻找适合于农药的先导筛选规则，对242个杀菌剂、512个除草剂和399个杀虫剂的5个描述符：疏水常数、相对分子质量、氢键给体数、氢键受体数、分子极性表面积和毒性进行了计算和分析，提出了杀菌剂、除草剂和杀虫剂先导化合物的筛选规则。

The studies on metabolic enzymes、synergists and neurobioassays suggest that the monooxygenases、esterase and decreased nerve sensitity are involved in resistance to pyrethroids in the resistant HJ-R strain . The resistance to both organophosphorus and carbamate insecticides is mainly caused by metabolic mechanisms. The significantly synergistic effects of Pbo infer that the resistance to carbamata may be principally attributable to monooxygenases detoxification.

代谢酶系、增效作用以及神经电生理研究表明，HJ-R种群对拟除虫菊酯类杀虫剂的抗性是由多功能氧化酶及酯酶代谢增强、神经敏感性降低几个因子综合作用的结果；对有机磷、氨基甲酸酯类杀虫剂的抗性主要是由代谢机制引起，与靶标部位敏感性降低机制抗性无关，Pbo对HJ-R种群突出的增效作用，表明多功能氧化酶代谢在对灭多威的抗性中可能起主导作用。

Enlarge effection of the mixture of. PB and Beta-cypermethrin accord with equation y =-0.0156x2 + O.I623x + 1.2098(r = 0.8862). Other several proportion of insecticide with PB is 5:1, Tetramethrin's enlarge effection is 2.51 times The Permethrin is 1.40 times, D-trans allethrin is 0.50 times, D-prallethein is 1.67 times ,80% DDV milk is 1.38 times.

PB对高效氯氰菊酯的增效作用符合方程y=-0.0156x~2+0.1623x+1.2098(r=0.8862)，以PB和其它几种杀虫剂的比例为5：1时，对敏感家蝇种群成虫的毒力增效倍数为胺菊酯2.51倍、氯菊酯1.40倍、右旋反式丙烯菊酯0.50倍、右旋丙炔菊酯1.67倍、80％DDV乳油1.38倍，各杀虫剂与PB混配均表现为相加作用。

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。
