异距琵甲(鞘翅目:拟步甲科)生物学特性的研究

异距琵甲在宁夏2年发生1代,以成虫和不同龄期的幼虫越冬,4月上旬至10月上旬产卵,卵期10～14 d,幼虫一般为12龄,幼虫期380～445 d;越冬幼虫于次年6月下旬至9月上旬化蛹,蛹前期16～28 d,蛹期14～20 d,羽化成虫经240～275 d性成熟开始交配产卵。该虫食性杂,不喜光,活动有明显的节律性。成虫具防御腺进行自卫,防御腺分泌物可作药物应用。

Biological characteristic of Blaps kiritshenkoi(Coleoptera:Tenebrionidae)

In this paper, morphological characters, living habits and life cycle of Blapa kiritshenkoi were described. It was known that B. kiritshenkoi completes one generation in two years. They hibernate with adults and different instars in soil and have generation overlapping. The eggs appeared from early March to early October, lasting for 10-14 days. In general, the larva had 12 instar stage, lasting for 380 - 445 days. The exarate pupae appeared from late June to early September. The prepupal stage lasted for 16-28 days and the pupal stage covered 14 - 20 days. In 200 - 275 days, they became sexually mature and began to copulate and lay eggs. B. kiritshenkoi is omnivoraous. The adults avoided light and their activity was obviously periodical . The adults could make use of the defensive gland to protect themselves. The secretion of their defensive glands is medically valuable.
