昆虫同所有的节肢动物一样,在一年的发育过程中,遇到高温或低温,往往有一段或长或短的生长发育停滞时期,通常称为越夏或越冬。越夏仅局限于少数虫种,或在高温季节里生活在不具备隐蔽生态条件下的虫种,而越冬则是寒带、温带,甚至靠近亚热带自然界里的所有昆虫几乎都要经历。现综合一些常见森林害虫的越冬虫态、越冬场所及据以采取的防治方法,介绍于下,以供参考。一、昆虫的越冬虫态昆虫的越冬虫态,因虫种不同而有差异。就是同一种昆虫,由于分布地区不同,也常不尽相同,有些几年1代的昆虫,其第 Insects, like all arthropods, experience high or low temperatures during one year’s development, often with long or short stasis, often referred to as summer or wintering. Summer is limited to a few species of insects, or insects that do not possess secluded ecology in the hot season, while wintering is cold, temperate and almost all insects near subtropical nature almost always experience. Now some of the common forest pests overwintering insect state, overwintering place and the method of prevention and control accordingly, introduced below, for reference. First, the insect overwintering insect overwintering insect state, due to different species of insects are different. Is the same kind of insects, due to the distribution of different regions are often different, some generations of a few generations of insects, the first
