本文通过室内饲养观察,对兴安落叶松鞘蛾(Coleophora dahurica Flkv.)成虫生物学特性及交配行为进行了研究。结果发现:其雄成虫出现的时间比雌成虫早24—36h。雌成虫羽化后24—42h为性信息分泌高峰期;羽化后30—48h的雄成虫对性信息素反应最敏感,故雄成虫提前羽化对交配有利。雌成虫无重复交配现象;雄成虫可重复交配,最多可达4次左右。雌、雄成虫在交配过程中有一定的行为反应。补充营养和交配次数对成虫寿命有一定影响。
In this paper, we studied the biological characteristics and mating behavior of Coleophora dahurica Flkv. The results showed that: the male adult appeared earlier than female adults 24-36h. Female adults emerge 24-42h after the peak of sexual information secretion; emergence of 30-48h adult male sex pheromone response is the most sensitive, so the male adult emergence in advance of matings favorable. Female adults without duplication mating phenomenon; adult male reproductive mating can be up to 4 times. Female and male adults have some behavioral responses during mating. Supplemental nutrition and mating frequency have a certain impact on adult longevity.
