弯齿琵甲生物学特性的研究

The biological characteristics of Blaps femoralis.

弯齿琵甲BlapsfemoralisFischer Waldheim在宁夏银川2年发生1代。以成虫和不同龄期的幼虫越冬,3月下旬至1 0月上旬产卵,卵期1 2～1 5d ;幼虫一般为1 1龄,幼虫期3 2 0～490d ;越冬幼虫于次年6月下旬至9月上旬化蛹,蛹前期1 2～1 8d,蛹期1 8～2 5d;羽化成虫经2 0 0～2 60d性成熟开始交配产卵。食性杂,不喜光,活动有明显的节律性。成虫具有利用防御腺进行自卫的特性,防御腺分泌物可为医学提供天然的药物。幼虫各项营养成分较高,是一种很有开发价值的资源昆虫。

In this paper, morphological characters, living habits and the life cycle of Blaps femoralis are described. It was known that B. femoralis completed one generation in two years. They hibernated as adults and larvae at different instars in soil and had overlapping generations. The eggs appeared from the late-March to early-October, and the egg stage had 12～15 days. The larva had 11 instars, and the larval stage had 320～490 days. The exarate pupa appeared from late_June to early-September. The prepupal stage had 12～18 days, the pupal stage 18～25 days. By 200～260 days,it would become mature and begin to copulate and lay eggs. B. femoralis was omnivorous. The adult was not attracted to light, and its living activities had an obvious periodicity.The adult could make use of the defensive gland to protect itself, and the secretions of the gland could be used as the crude medicine. The larva is also a resource insect with potential value.
