摘要
昆虫种群数量变化既体现了昆虫种群演化过程中的变异和趋势,又体现了昆虫种群对生态环境的响应,而虫口统计学是研究昆虫种群数量变化的理论基础,是探索昆虫种群变化机制的重要工具和途径。本文概括虫口统计学的概念与内涵、研究方法、应用领域,并对其前景进行了展望,以期为虫口统计学在昆虫学研究中的应用提供理论基础。
Insect demography is an emerging subdiscipline of classical human demography that brings insect life table techniques to bear on matters concerned with the basic determinants of abundance, dynamics processes, tendency, and pattern of insect populations. Also, the ecological mechanism of population dynamics is explored to reveal processes, properties, and characteristics of insect populations.The concept, applications, technology, and prospect of insect demography were summarized to reveal statistical tables of insect cohorts from birth to death. The new tendency for the use of insect demography in the studies of conservation biology and forensic entomology was suggested, and a globally interdisciplinary perspective on entomology and ecology into the demography theory was integrated. The basic demographic concepts of insect longevity and applied entomology were expanded.
