摆在昆虫学家面前的主要任务之一是,预先估测各种林分对害虫危害的抗性以及害虫在某一林分大量繁衍爆发性发展的潜在可能性。当前正在应用的估测林分潜在抗性的方法是,对所研究的害虫种群的最适栖息环
One of the major tasks facing entomologists is to anticipate the potential for resistance of various stands to pests and for the potential for a large number of pests to multiply in the forested area. The currently applied method of estimating the potential resistance of stands is to optimize the habitat ring for the pest population studied
