矢尖蚧是近年来柑桔生产上发生最普遍、危害性最大的害虫之一。对矢尖蚧进行药剂防治,不仅时间不易掌握,而且迄今尚无药剂防治的虫口指标,喷药往往带有盲目性。此外,由于矢尖蚧有固定生活、早期星点发生的特点,故在生产上有重剪虫枝的防治方法,但控制效果究竟有多大尚无报道。如果主要采用修剪控制,辅以化学防治,其虫口指标又如何?为探索上述问题,我们于1984～1990年在内江市东兴区和资阳县进行了本调查及试验。
Agrimony scale is one of the most common and harmful pests in citrus production in recent years. Medicine on scale Agrioblastum control, not only difficult to grasp the time, and so far no pesticide control indicators of insects, spraying often with blindness. In addition, due to the fixed life of Agkistrodon acutus, the early occurrence of the characteristics of the star, so the production of heavy shear worm control methods, but how much control effect has not yet been reported. If the main use of pruning control, supplemented by chemical control, its insect population index? In order to explore the above problems, we conducted in 1984 and 1990 in Neijiang Dongxing District and Ziyang County conducted the survey and test.
