矢尖蚧(vnaspis yanonensis kuwana)是我国柑桔产区危害相当严重的害虫。也是我区柑桔的主要害虫之一。由于矢尖蚧成蚧抗药性强,我区又缺乏科学的测报方法指导防治幼蚧,因此,生产上对此虫的防治感到非常困难,常使用高浓度剧毒药剂来防治,结果不但防治效果差,而且大量杀伤天敌,使害虫更加猖獗为害,为了弄清矢尖蚧在广西的发生情况及用科学的测报方法来指导防治,本研究自1986年起至1992年系统进行了矢尖蚧生活史饲养和发生期预测方法的研究,现将研究结果整理如下:
Vaspis yanonensis kuwana is a pest that is seriously endangered in our citrus producing areas. It is also one of the main pests of citrus in our area. Because of the scale insects Kuwana resistance is strong, our district and lack of scientific reporting methods to guide the prevention and control of juveniles, therefore, the production of insect prevention and control of this very difficult, often using high concentrations of highly toxic agents to control, the results not only prevention and control effects In order to find out the occurrence of Agkistrodon acutus in Guangxi and to guide the prevention and cure by means of scientific reportage, this study systematically carried on the life of Agkistrodon elegans from 1986 to 1992 History of feeding and the prediction of the occurrence of the method, the results are summarized as follows:
