摘要
在宁夏银川室内自然条件下研究了突角漠甲的生物学特性.结果表明,突角漠甲3a发生1代,以成虫和不同龄期的幼虫在沙土中越冬;成虫于4～9月份交尾产卵,卵期为10～14d;幼虫一般为7龄,幼虫期长达1.8～2.0a,幼虫经过2次越冬于第3年6月中旬至8月下旬化蛹,蛹期为10～12d;羽化成虫经210～280d性成熟开始交配产卵.成虫喜清晨和傍晚活动,为典型的黄昏性昆虫.
The biological characteristics of Trigonocnera pseudopirnelia are observed in the natural and indoor condition in Yinchuan of Ningxia in this paper. Trigonocnera pseudopimelia completes one generation in 3 years. It hibernates with the adult and the larva of different instars in soil. The egg appears from April to Septemper, the egg stage is 10-14 days. In general, the larva has 7 instars, the larva stage is 1. 8 to 2 years. The second overwintering larvas pupate from midJune to late-Auguest in the third year, the pupal stage is 10 to 12 days. By 210 to 280 days, the adult has mature sex and begin to copulate and lay eggs. The adult like to move about early in the morning and at sunset, it is a typical dust insect.
