摘　　要：于2008～2010年在康定对大栗鳃金龟成虫的出土、取食，特别是交配、产卵等方面进行了研究。结果表明：在康定，成虫4月底开始出土，5月中旬至6月下旬为出土高峰期。成虫可进行多次交配，一次交配过程可以分为3个阶段，即交配前、交配中和交配后，平均交配时长为115．6min±24．4min（n=10）。交配日节律呈“M”形，分别在中午和晚上有一明显的高峰期。产卵前，成虫在地表以下10cm左右做一圆形产卵室，将卵产于其中，堆状分布，初产卵粒为浅黄色，随后颜色逐渐变深。每室产卵33．7粒±7．0粒（n=10）。The habit of emergence, feeding, mating and oviposition of adult Melolontha hippocastani mongolica were in- vestigated in Kangding from 2008 to 2010. The eclosion of adult M. hippocastani mongolica was finished in the end of April with a peak between mid May and the last ten days of June. The adult 11/1. hippocastani mongolica would mate for several times and usually last for 115.6 min± 24.4 min （n = 10）, and the mating rhythm presented a shape of ＂M＂ with two peaks at noon and night respectively. Before oviposition, the female would make a round chamber about 10 cm underground, which was used for laying eggs. New eggs were pale-yellow and the colour would be darkened as time went on. The average egg numbers were 33.7 ± 7.0 per chamber （n = 10）.
