柑桔吉丁虫是柑桔生产上毁灭性害虫之一。近几年来已由点片发生,迅速蔓延到整个桔园地区,造成大量桔树死亡。据一九七一年春不完全统计,仅桔园公社新丰大队因受此虫为害而死亡的桔树,约在5%以上,另有许多的桔树因受害而极度衰弱,严重减产,损失甚大。为了解决此虫的防治问题,我们从一九七一年春开始在吸收外地经验进行大面积防治的同时,针对防治上存在的问题,积极开展群众性科学实验。现将结果整理如下,供生产上参考。
Citrus jitie is one of the devastating pests on citrus production. In recent years, it has been spotted and spread rapidly to the entire Orange Garden area, resulting in the death of a large number of orange trees. According to incomplete statistics in the spring of 1971, only about 5% of the orange trees killed by the Xinfeng Brigade in the Orange Park commune due to the pest were severely weakened, causing serious losses in production and losses. Very big. In order to solve the problem of prevention and control of this pest, we started from the spring of 1971 to conduct large-scale prevention and control while absorbing foreign experience and actively conducted mass scientific experiments in response to the problems in prevention and control. The results are now organized as follows, for the production of reference.
