荔枝椿象分布福建、广东、广西等省区,是荔枝、龙眼的主要害虫,近年来其为害颇为严重。例如福建晋江县,1953年龙眼受害减产22%,损失3万担青果;广东从化县,1958年全县35万多株荔枝,遭到严重威胁,轻者减产,重者全部失收。以往各地对于此虫也曾积极进行防治研究,但都偏重于选择有效药剂方面的试验,由于这种害虫的寿命长,繁殖力大,发生时期不整齐、越冬场所又复杂等等,在防治上有一定的困难。如果单纯依靠某一种防治方法,是很难达到满意的效果。惟本文乃根据福建群众经验并结合试验研究成果,较系统地介绍了荔枝椿象的综合防除法,可供各地参考试用。
Distribution of litchi stinkbug Fujian, Guangdong, Guangxi and other provinces and autonomous regions, is the litchi, longan the main pests in recent years, its damage is quite serious. For example, in Jinjiang County, Fujian Province, the longan suffered a 22% loss in production and a loss of 30,000 tons of green fruit in 1953. In Conghua, Guangdong, more than 350,000 litchi trees were found in the county in 1958, causing serious threats and losses. In the past, various insects have also actively conducted research on prevention and treatment of this pest, but all have focused on trials of selecting effective pharmaceutical agents. Due to the long life span of the pests, the large fecundity, the irregular period of occurrence, the complex places for overwintering, etc., There are certain difficulties. If you rely on a simple method of prevention and control, it is difficult to achieve satisfactory results. However, this article is based on the experience of Fujian people combined with experimental research results, a more systematic introduction of litchi stinkbug comprehensive prevention and control law for reference around the trial.
