摘要
为扁角豆芫菁的人工规模化养殖提供参考，对其繁殖习性进行了观察。结果表明：扁角豆芫菁的性行为包括求偶和交配2个阶段；成虫羽化后4～5d有求偶行为，求偶成功后便开始交配，雄虫一生可交配2～4次，雌虫1～3次，交配适宜温度为27．6～30．5℃，相对湿度为72．4％～86．3％；雌雄比例为1∶2时雌虫平均交配次数最多，达2．3次；交配后4～6 d开始挖穴产卵，交配1次产卵1次。雌虫一次产卵45～110粒，产卵间期为7～10 d。
The reproductive habit of E.impressicornis was observed to provide a reference for artificial large scale breeding of E.impressicornis.The sexual behavior of E.impressicornis includes two stages of courtship and mating.The adult has the courtship behavior 4～5 d after emergence and begin to mate after successful courtship.The mating times of the female and male adults are 2～4 and 1～3 respectively.The optimum mating temperature and relative humidity is 27.6～30.5℃ and 72.4%～86.3% separately.The average mating times of female adults reaches 2 .3 （the highest）when the proportion of female/male adult is 1∶2.The female adults begin to lay eggs 4～6 d after mating.One mating provide one oviposition and the egg number is 45～110.The oviposition interval is 7～10d.
