黑胸大蠊的生物学研究

Studies on the Biology of Experimental Population of Smoky Brown Cockroach

１９９１～１９９２年在实验室条件下，对黑胸大蠊生物学进行了系统研究。黑胸大蠊完成一个世代需３２４．９３天。成虫于４月下旬开始羽化，至８月下旬结束，高峰是５月下旬（♂）和７月上旬（♀）。雌成虫于５月中旬开始产卵，至翌年１月下旬结束，高峰是７月下旬，产卵前期１５．１±０．７４天，产卵期１５５．３±１２．９天，产卵后期２９．３±８．４天。每头雌成出产卵鞘２７．６７±２．１７个。产卵间隔时间６．７５±０．６８天，成虫寿命２０２．３±１６．４５天。卵鞘历期４６．０３±１．６８天。每个卵鞘含卵２０．５１±０．９７粒。若虫有８～９个龄期，经７～８次蜕皮后变为成虫。大部分（８５．７１％）雄性若虫经７次蜕皮变为成虫，大部分（７５．００％）雌性若虫经８次蜕皮变为成虫，若虫历期２６３．８天。

Systematic investigations on the biology of smoky brown cockroach Periplaneta fuliginosa Serville under laboratory condition were carried out in 1991-1992.The occurrence periods of whole generation,egg-case,each instar of nymph and both sexs of adult,including reproduction period of female their body lengths and weights morpkology of egg-case and each instar of nymph,molting times of male and female nymphs,lifespan of male and female adult,fertility and hatching rate of this cockroach were determined.
