摘　　要：戈壁琵甲2年发生1代,世代不整齐,以成虫和不同龄期的幼虫越冬.成虫4月上旬至9月下旬产卵,卵期为8～12d, 幼虫一般为12龄,幼虫期为1～1.5a,越冬幼虫于次年6月下旬至9月上旬化蛹,蛹前期为40～45d,蛹期为12～20d,羽化成 虫后经280～300d性成熟,开始交配产卵.戈壁琵甲食性杂,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,其防御腺分泌物可成为医学上的天然药物,该幼虫各项营养成分较高,是一种很有开发价值的昆虫资源.This paper described morphological characteristics, living habits and life cycle of that Blapss gobiensis. It is known that Blaps gobiensis completes one generation in two years in laboratory condition. They hibernate with adult and larva of different instars in soil and have generations overlapping. The egg appears from the early-April to last-September, the egg stage is 8—12d. In general, the larva has 12 instars, the larva stage is 1—1.5 years. The exarate pupa appears from last-June to early-September. The prepupal stage is 40—45d, the pupal stage is 12—20d. For 280—300d,it has mature sex and begin to copulate and lay eggs. Blaps gobiensis is an omnivorous insect and has clear rhythm.The adult could make use of defensive gland to protect itself, the secretion of defensive gland could provide medicine with crude medication. All kinds of nutritional components of the larva is relatively high, it is also a sort of resource insect that has a potential exploiture value.
