摘要
在自然界中,螳螂种群数量的增长受到多种因素的制约。作者通过野外调查和实验室饲养观察,以及对国内外相关资料的查阅,对这些主要制约因素逐一进行了分析和归纳。在影响螳螂分布与制约种群数量增长的这些因素中,自然条件中的温度是关键的制约因素,食物、天敌、自残行为、人类活动等是重要的制约因素。
There are many Iimiting factors which affect population growth of praying mantids in nature. After reading references, investigating in field and rearing some species in laboratory, we drew a conclusion for these limiting factors in this paper. Natural condition is the most important factor, in which the distribution of Mantodea species is restricted mainly by temperatrue as well as food, natural enemies, cannibalism, and the action of human beings, affect the population growth of praying mantids greatly.
