Dichlorvos was once a good product and widely used for its outstanding effect on knocking down insects and easy volatilizing. But DDVP and chlorpyrifos are limited to use for the reason of safety. According to the recommendation of WHO, a new miticide,pirimiphos-methyl, was developed by Hunan chemical academy in 1999. It can be used for controlling mosquitoes, flies, cockroaches and mites et al.

有机磷杀虫剂中的敌敌畏由于具有击倒作用与杀灭能力较强，又有自然挥发功能，所以，是应用最广的品种，但DDVP在卫生杀虫剂中已处于限制使用状态。1999年，湖南化工研究院，根据WHO的推荐，研制开发了广谱，速效杀虫，杀螨剂—甲基嘧啶磷，可用于防制蚊，蝇，蟑螂和螨等。

Dictamnus dasycarps Turcz. also have insecticidal activity to Ostrinia furnacalis, When the concentration was 10g/ml, correct decreased rate reached 92.86%, When the concentration was 0.675ml/g, the correct decreased rate reached 3.57%; Dictamnus dasycarps Turcz. at the range of testing concentration have lower stomach toxic effects to Ostrinia furnacalis.

通过白鲜皮对玉米螟杀虫活性的初步研究表明：白鲜皮对玉米螟表现出很强的拒食活性，在测定浓度范围内其拒食活性均在80％以上，最高可达97.22％。；白鲜皮提取液对玉米螟也有一定的毒杀活性，当浓度为10g／ml时其校正死亡率可达到92.86％，浓度为0.675ml／g时校正死亡率仅为3.57％；白鲜皮在测定浓度范围内对玉米螟的胃毒活性较低，最高才42.86％。

The resources and pathogenicity of entomogenous fungi in Lishan National Nature Reserve in the southern east of Shanxi Province were studied.

对地处山西东南部的历山国家级自然保护区的虫生真菌种类资源及其杀虫活性作了初步的研究。

Screening toxic proteins to M alternatus from entomogenous fungi is the base of control pest. It will reveal the mechanism how the fungi infect their host from the view of biochemistry and molecular biology, and base for culture trees of anti-longhorn beetle.
