广西白蜡生产失败原因剖析

广西白蜡生产失败的主要原因是，首先，年降雨量超过１５５２ｍｍ，间接或直接地引起大批白蜡虫死亡；其次，对白蜡虫具有毁灭性的白蜡虫寄生蜂不采取任何防治措施，致使种虫寄生率高达９２．９％。因此，白蜡生产遭受失败。广西气候多种多样，年降雨量、在１５５２ｍｍ以下有２２个县，发展白蜡生产是有潜力的，可逐步恢复和发展白蜡生产。

The Analysis of the Causes of White Wax Production Failure in Guangxi

The causes that result in failure of production of white wax in Guangxi are, firstly, overmuch annual rainfall (above 1 552 mm), the rainfail upper limit is about 1 552. 5 mm, under the limit, the production would be successful; secondly, the parasitic bee of white wax scale had not been controled, with the result that the parasitic rate to the seed insects is up to 92. 9%. But,in Guangxi there are 22 counties where the annual rainfall is less than 1552. 5 mm, the white wax production would be resume and develop gradually.
