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.
