| 摘 要： | 从生物学和生态学特性方面探讨了影响异色瓢虫种群数量的因子,研究表明,温湿度、食物充足程度、自残习性以及农药的使用等方面都对异色瓢虫种群数量产生影响:最适温度为20~30℃;食物短缺情况下,具有自残习性;施用杀虫剂,直接影响其捕食能力和成活率。

| Abstract: | Influencing factors for population of ttarmonia axyridis were discussed from aspects of biological ＆ ecological characteristics. Result shows that temperature ＆ humidity, degree of sufficient food supply, self-inflicted characteristics as well as the use of pesticides etc. all have influences on population ： optimum temperature is 20-30 ℃ ; in the case of shortage of food, they have self-inflicted characteristics ; applying insecticides influence their predation capacity ＆ survival rate. |
