马尾松毛虫在我国每年发生近2,000万亩,严重影响了马尾松和几种国外引种松的生长,是我国最重要的森林害虫之一。了解和掌握松毛虫蛹期及成虫期的生物学特性,对于开展性信息素工作的研究及遗传防治等,有一定的帮助。1977年第三代,1978年越冬代和第一代,我们对松毛虫蛹期及成虫期的生物学特性进行了连续的观察,现将结果整理如下: 一、蛹 期
Masson pine caterpillars in our country each year nearly 2,000 mu, seriously affected the masson pine and several foreign introduction of pine growth, is one of the most important forest pests in our country. Understanding and mastering the biological characteristics of the pupae and adult stages of pine caterpillars can be helpful for the research on sex pheromone and genetic control. The third generation in 1977, the overwintering generation and the first generation in 1978, we conducted a continuous observation of the biological characteristics of the pupal and adult stages of the pine caterpillar, the results are summarized as follows: First, pupal stage
