【摘要】 拟孔蜂巨柄啮小蜂(Melittobia acasta)是火红拟孔蜂(Hoplitis pyrrhosoma)的一种寄生天敌。观察表明,该蜂还可寄生于伏暗蜂(Stelis franconica)、蜂虻(Anthrax spp.)、短毛异蜂虻(Hemipenthes volutinus)、郭公虫(Trichodes spp.)和缘条蜂(Anthophora altaica)的幼虫。在恒温22℃、24℃、26℃、30℃的实验条件下,测定了其发育历期和生殖力等参数。结果表明,该蜂的发育起点温度为16.93℃,有效积温为617.04日度。在22℃-30℃,随温度升高,该蜂的发育历期缩短。在24℃该蜂产卵量最大,30℃时种群的内禀增长率最大更多还原

【Abstract】 Melittobia acasta is the major parasitoid of Hoplitis pyrrhosoma . The results indicated that it could oviposite into the larvae of Hoplitis pyrrhosoma and other larvaes ( Stelis franconica , Anthrax spp. , Hemipenthes volutinu , Trichodes spp. and Anthophora altaica). At constant temperature (22℃ , 24℃, 26℃ , 30℃ ), we obtained the effect of temperature on development time and reproductive ability. The threshold development temperature and effective temperature sum of Melittobia acasta were 16.93℃ and 617.04 day-degree respectively. At constant temperature (22℃ , 24℃ , 26℃ , 30℃ ) , the development time became shorter with the temperature rising. At 24℃ , Melittobia acasta could produce the largest amount of egg oviposition, at 30℃ Rm of the population was the highest更多还原
