萍灰螟是绿萍的毁灭性害虫,过去对此虫的研究甚少,它的越冬虫态、场所,食性与寄主,以及世代问题,学名及分类等尚不清楚。我们遵照毛主席关于“自然科学是人们争取自由的一种武装。……人们为着要在自然界里得到自由,就要用自然科学来了解自然,克服自然和改造自然,从自然里得到自由”的教导,一九六五年起对此虫进行了一些调查和饲养观察,现将所得结果简介于下,供参考。

We follow Chairman Mao’s argument that “natural science is an armed struggle for freedom.” In order to be free in nature, people must use natural science to understand nature, overcome nature and transform nature, and enjoy freedom from nature " . Since 1965, some surveys and rearing observations have been conducted on the insects. The results obtained are summarized below for reference.
