A SIMULATION OF INTERSPECIFIC RELATIONSHIP BETWEEN WOOLLY APPLE APHID ERIOSOMA LANIGERUM (HAUS.) AND ITS PARASITE APHEL1NUS MALI (HALD.) 1 . THE COMPARATIVE STUDY OF BIOLOGY AND ECOLOGY OF WOOLLY APPLE APHID AND ITS PARASITE
摘 要 :本研究通过对苹果绵蚜(Eriosoma lanigerum Haus.)和苹果绵蚜蚜小蜂(Aphelinus mali Hald.)的生物学和生态学特性的比较分析,得到如下结论:(1)苹果绵蚜完成一世代的积温要求和发育起点温度均低于苹果绵蚜蚜小蜂,二者的有效积温分别为352.19日度和375.51日度,发育起点温度分别为7.62度和7.95度。因此,苹果绵蚜较其寄生蜂更适合于昆明地区的气候条件;(2)苹果绵蚜种群的增长能力大于苹果绵蚜蚜小蜂,二者的内禀增长率在20℃下分别为0.1390和0.1146,在25℃下分别为0.2647和0.1628。这可能是昆明地区苹果绵蚜蚜小蜂不能控制苹果绵蚜为害的主要原因。另外,本研究首次利用卡方密度函数对各种温度下的昆虫产卵的时间分布进行了拟合,取得了较好的效果。
Abstract:This paper dealt with the comparison of ecology and biology of Eriosoma lanigerum (Haus.) and its parasite, Aphelinus mali (Hald.), The results are as follows. (1) The effective accumulative temperature for completing a generation and basic developmental temperature of aphid are smaller than those of its parasite, and their effective accumulative temperatures are 352.19℃and 375.51℃ and basic developmental temperatures are 7.62℃ and 7.95℃,respectively. These indicate that aphid is more suitable than its para...
