| 摘 要： | 木奈树桑白蚧在福建浦城１年发生３代，以受精雌成虫在枝干上越冬；雌雄比接近于１１；雌虫平均产卵量为４８～８７粒．通过实验，建立了木奈树桑白蚧捕食性天敌日本方头甲的Ｈｏｌｉｎｇ功能反应模型和Ｈａｓｓｅｌ－Ｖａｒ－ｌｅｙ干扰反应模型，同时测定了瞬时攻击率、处理时间、最大理论捕食量、干扰常数、搜寻常数

| Abstract: | Mulberry scale (Pseudaulacaspis pentagona) on Nane tree develops 3 generations a year in Pucheng County, Fujian Province and sex ratio is near 1∶1, a female lays 48￣87 eggs on an average. Holling models of the functional responses and Hassell Varley models of the interactive responses of Cybocephalus nipponicus were developed by experimental methods. And the parameters of instantaneous attacking rate, handling time and maximum theoretical predatory amount, mutual interference constant and quest constant were estimated. |
