鼎突多刺蚁群体结构和生活史的研究

本文报告了鼎突多刺蚁(Polyrhachis vicina Roger)的群体结构和生活史。通过研究表明,鼎突多刺蚁一年发生一代,以蚁后、雄蚁、工蚁、幼虫和卵越冬。卵和幼虫在冬天发育停滞(或极慢)。到了春天,随着气温的上升,卵和幼虫又恢复正常发育。据室内人工饲养观察,卵的发育历期为23.8±2.5天(平均温度26℃)幼虫为20.4±4.4天(26℃),工蚁蛹为19.8±5.5天(27℃)。成长工蚁在5—11月出现;8—11月,雄蚁从蛹中羽化;10月,雌蚁从蛹中羽化。雌蚁分飞交尾后,进入邻近蚁巢或回到原巢,脱翅成为蚁后。蚁巢内存在着多后现象。

STUDIES ON COLONY STRUCTURE AND LIFE CYCLE OF THE SPINED ANT, POLYRHCHIS VICINA ROGER

This paper reports studies on colony structure and life cycle of the spined ant, Polyrhachis vicina Roger, studies were carried out at hillsides 10 kilometers from southeast of Yongkang town, Zhejiang province and in the laboratory during the period from 1984 to 1986. One crop of adults was produced each year. They overwintered as queens, males, workers, eggs and Larvae. The eggs and larvae in the winter showed little growth until the following spring, When the weather became warm and then development proceeded rapidly. Adult workers emerged continuously from May to November, males eclosed from August to November, while females eclosed only in October, females entered home nests or other neighbouring nests after mating flights, and then lost their wings and became queens. The nests were polygynous.
