矢尖蚧Unaspis yanonensis Kuwana分布于我国、日本、朝鲜和法国。是柑桔上一个重要的顽固性害虫。此蚧在我国历史上较少成灾,70年代中期以后才逐趋严重。由于成蚧抗药力特强,又缺乏我国自己的科学测报方法指导防治幼蚧,在虫灾严重时仅靠使用高浓度剧毒药剂,结果不但防治效果极差,而且杀伤了大量的天敌,使害虫更加猖獗成灾。为了解决此一问题,笔者在国内外研究工作的基础上,于1977—1985年在重庆桔区开展了本测报法的研究。
Unaspis yanonensis Kuwana is distributed in China, Japan, North Korea and France. Citrus is an important stubborn pest. This scale is less disastrous in the history of our country and gradually aggravated by the mid-1970s. Due to the extremely strong resistance to insects, but also the lack of China’s own method of scientific reporting to prevent and control juvenile Kei scale insects serious serious use of high concentrations of highly toxic agents, the results not only very poor control effect, but also killing a large number of natural enemies, pests More rampant disaster. In order to solve this problem, on the basis of domestic and foreign research work, the author carried out the study of this report method in Orange District of Chongqing from 1977 to 1985.
