摘要
在实验室条件下，研究了黄绒螟和小腹螟两个种群的繁殖成功率和发育时间的变异。以两种褐皮螟(Ziway和Melkasa) 4龄幼虫与两种褐皮螟(Ziway和Melkasa) 1日龄的交配成虫接触，研究其繁殖成功率的差异。在20°C、25°C、28°C和30°C 4种温度条件下，研究了不同地点黄颡鱼种群的发育时间。实验采用完全随机设计。当寄主和寄生蜂来自同一地点时，寄主内死幼虫数和茧内死幼虫数显著低于寄生蜂(p)。紫椒;Melkasa人口;人口互动;Ziway人口。埃塞俄比亚生物科学杂志Vol. 5 (2) 2006: pp. 177-188
Population Variability and Developmental Time Studies of Cotesia flavipes Cameron (Hymenoptera:Braconidae) Reared on Different Populations of Chilo partellus Swinhoe (Lepidoptera: Crambidae)
Variability of two populations of Cotesia flavipes and Chilo partellus was studied for reproductive success and developmental time under laboratory conditions. Fourth instar larvae of two populations of C. partellus (Ziway and Melkasa) were exposed to a day old mated adult female of two populations of C. flavipes (Ziway and Melkasa) to study the variability in reproductive success. The developmental time of the two geographical populations of C. flavipes reared on C. partellus obtained from the two different locations was also studied under four temperatures (20°C, 25°C, 28°C and 30°C). The experiments were designed in a complete randomized design. When both the parasitoid and the host were from the same location, the number of dead larvae inside the host and dead cocoons were significantly lower (p Keywords : Cotesia flavipes ; Chilo partellus ; Melkasa population; population interaction; Ziway population.
