油茶地蜂Andrena camellia Wu是江西、湖南等地油茶花期主要传粉昆虫之一。2006-2007年在江西宜春对油茶地蜂除成虫外各虫态的形态特征、生活史及幼虫和成虫的行为等生物学特性进行了观察研究。结果表明:该蜂在江西宜春1年发生1代。成虫10月中旬开始出巢活动,雄蜂早于雌蜂3d左右出现,完成交尾后数日死亡,雄蜂出巢后寿命18d左右,雌蜂约38d。卵期约8d。幼虫期24d左右,幼虫取食完花粉球后长成老熟幼虫进入滞育期,滞育期约241d。翌年9月中旬开始化蛹,蛹期约30d。出土后的雌蜂当天就可以交配,交配后的雌蜂在羽化地点附近选址筑巢,采集油茶的花粉和花蜜于虫室中制成球形蜂粮并在上面产卵,每粒花粉球上产卵一枚。
Andrena camellia Wu is one of the major pollinators in the flowering period of camellia in Jiangxi and Hunan. The morphological characteristics, life history, larvae and adult behavior of each insect except the adult camellia were studied in Yichun, Jiangxi Province from 2006 to 2007. The results showed that the bee occurred one year in Yichun, Jiangxi Province. The adults began to go out of nest in mid-October. The drone appeared earlier than the females 3d and died several days after mating. After the drones exited the nest, their longevity was about 18 days, and the females spent about 38 days. Egg period of about 8d. Larvae about 24d, the larvae fed pollen ball grow into mature larvae into the diapause period, diapause period of about 241d. Mid-September the following year began to pupate, pupal period of about 30d. After the unearthed female bees can be mated the same day, the mating female females nest in the vicinity of the feather site selection, collection camellia pollen and nectar in the worm room made of spherical bee food and spawn above, each pollen ball One spawn.
