Abstract

The life cycle, bionomics and mature larval structures of the Japanese prionocerid species, Idgia iriomoteana Nakane, 1980 were investigated in captivity. The results showed that I. iriomoteana has the following characteristics: (1) the larval morph is less advanced in terms of miniaturization, and larvae pass seven larval molts before they pupate; (2) the life cycle is univoltine with summer, not winter, dormancy; (3) the first instar larvae are larger than the size of the egg, but foetomorphic larval instar (which is observed in the Melyridae: Malachiinae) is not shown. Based on comparison with melyrid species, the degree of miniaturization, dormancy behaviour, adaptation to the tropical and subtropical climates and the adaptive significance of a large first instar larva are all discussed. This study is the first to report the complete life cycle of a member of the family Prionoceridae.

鸢尾虫的幼虫结构和生物学特性（鞘翅目：隐尾虫科）

对1980年人工饲养的日本鸢尾虫（Idgia irimotoeana Nakane）的生命周期、生物学特性和成熟幼虫结构进行了研究。结果表明，虹彩虫具有以下特征：（1）幼虫形态在小型化方面不太先进，幼虫在化蛹前经过7次幼虫蜕皮；（2）生命周期与夏季、而不是冬季、休眠期是单向的；（3）一龄幼虫大于卵的大小，但未显示卵形态幼虫龄（在Melyridae:Malachiinae中观察到）。通过与联吡啶物种的比较，讨论了大型一龄幼虫的小型化程度、休眠行为、对热带和亚热带气候的适应以及适应意义。这项研究首次报道了隐孢子虫科成员的完整生命周期。
