火红拟孔蜂的生物学特性

首次报道了火红拟孔蜂除雌性成虫以外的各虫态形态特征、生活史、生殖发育及性行为等生物学特性。该蜂在西鄂尔多斯地区一年发生一代。越冬幼虫翌年4月中旬开始化蛹；预蛹约d左右；蛹期约15d。成虫5月上旬陆续羽化出茧；雄蜂早于雌蜂数日出现，雄蜂交尾后不久死去，寿命约为10d左右。雌蜂寿命约30d。卵期约3d左右。老熟幼虫多数在6月中下旬结茧后进入滞育状态，幼虫期长达300d左右。滞育幼虫通过人工控制温度可提前打破滞育或推迟其羽化的时间。

Biological Characters of Hoplitis pyrrhosoma

This paper first reports the biological characteristics of Hoplitis pyrrhosoma , such as morpha, not including female adult, life history, sexual behavior, generation and development, etc. This kind of bee takes place one generation in one year in West Erdos region. It hibernates in state of diapause larva, and starts to pupate in mid April of the next year. The prepupal period is as short as about one day, and pupal period is about fifteen days. The adult's eclosion time is different individually, from early May to late June. The male appears a few days earlier than the female, dies soon after mating, its life span is about 10 days. The female's life span about 30 days. The ovum is about 3 days in period, but the larval stage is as long as about three hundred days. Most last instar larvae begin to callus in mid and late June, and enter diapause state. Diapause larvae hibernate in the folloculi. Through controlling temperature artificially the diapause can be broken ahead of time, furthermore the eclosion may be postponed.
