Avermectin are 16-membered pentacyclic lactone compounds produced by Strephomyces avermitilis, which have extensive and high effect on many kinds of insect and mite.

阿维菌素是从阿维链霉菌的发酵产物中分离出来的16元大环内酯类抗生素，对多种动物寄生虫及农业害虫害螨有很高的杀虫活性，但是该药剂光照易降解而持效期短。

Thus, introduction of statine has become an efficient strategy for the the design of aspartic protease inhibitors.The unique properties of the ferrocenyl group has made ferrocene and its derivatives very popular molecules for biological applications.Among them there are compounds with antiproliferative effect,antibiotics,pesticidal activity,ect.

二茂铁自被合成以来因其具有许多独特的性质而受到广发的应用，许多二茂铁化合物具有抗菌、抗肿瘤、杀虫等活性，用它取代具有生物活性分子中某些芳香环或杂环可以提高整个分子的活性。

In addition, the research on fumigation activity against Sitophilus zeamais in vacuity warehouse and warehouse is showed that the fumigation toxicity is lower in warehouse than in vacuity warehouse.

另外对玉米象的空仓试验与模拟实仓试验表明实仓条件下苦杏仁精油对玉米象的熏蒸杀虫活性低于空仓条件下的活性。

The preliminary bioassay showed that all compounds had certain fungicidal and insecticidal activities. The inhibition rates of compounds 5f and 5h were above 95% against Colle-totrichum gossypii at 100 mg/L, and the mortality rates of compounds 5g and 7d were above 85% against Tetranychus urticae at 250 mg/L.

初步生物活性测定结果表明，在试验浓度下，目标化合物均具有一定的杀虫和抑菌活性，其中化合物5f和5h在100 mg/L浓度下对炭疽病菌的抑制率达95%；化合物5g和7d在250 mg/L浓度下对棉红蜘蛛的致死率达85%。

Objective To determine the oviposition responses of Anopheles sinensis to bacteria A4, Aeromonas sp. and Enterobacter sp. and whether or not the three strains attracted the mosquitoes, providing theoretical and experimental evidence for the application of the three bacteria in the intervention of malaria. Methods Blood?fed and held for 48-60 h, copulated female An.

目的 具吸引作用的细菌或其挥发物能提高按蚊与杀虫或抗疟工程细菌接触的机会，为此，拟测定中华按蚊对A4细菌、气单胞菌和肠杆菌的产卵反应特性，以明确3种细菌对中华按蚊是否具有吸引特性，为应用这3种细菌开展阻断疟疾传播研究提供理论和实验依据。

The average concentration in No.1 warehouse was reduced by 5.3%in each day when fumigating for seven day.

与无薄膜的全仓环流熏蒸试验相比，膜下环流熏蒸磷化氢浓度达到均匀的时间短；气密性好，熏蒸时取得的Ct值大，杀虫效果更好。

When i was young, i often saw many people busy in the garden, digging and hoeing the grass, carrying and irrigating, kiling the insec and fertilizing...until the harvest, and then preparing for the seeding for next season, it was quite happy.

小的时候，经常看到许多人在菜园里忙这忙那。每天不停地挖地锄草，挑水浇水，杀虫施肥……直到收到果实。然后又准备下一季的播种。这是一件非常开心的事。
