贵州仁怀斯氏蜜蜂茧蜂研究

Study on Syntretomorpha szaboi(Hymenoptera,Braconidae,Euphorinae)

调查发现,在贵州仁怀野外常有斯氏蜜蜂茧蜂快速攻击野生和家养中蜂,并在中蜂体内产卵,中蜂返巢后,体内已有斯氏蜜蜂茧蜂的卵。观察发现,斯氏蜜蜂茧蜂可在野生和家养中蜂巢内完成世代发育。对贵州仁怀斯氏蜜蜂茧蜂(标本)与印度产斯氏蜜蜂茧蜂(电镜照片)形态进行比较,发现并无形态上的差异。由于中蜂起源于中国西南地区,估计印度北部的斯氏蜜蜂茧蜂是随着中蜂携带进入或从中国西部自然传入。

Syntretomorpha szaboi Papp is a harmful solitary endoparasitoid which attack and parasitize the oriential honey bees Apis cerana Fabricius, parasitized bees are sluggish and die young. Similar oviposition and foraging behavior of flower visiting by S.szabdi has been observed, it is certainly that wild and domestic foraging adult oriential honey bees are attacked and parasitized in a rapid movement while visiting flowers in the wild of Renhuai, Guizhou. Genrally, an egg has laid in each bee host by piercing the ovipositor through the membrane between the second and third abdominal segments when the both of wild honey bee and domestic honey bee fled nonstop from wild to hive. The geographical range of the host, Oriental honey bees Apis cerana cerana Fabricius, extends westward as far as Xinjiang in China, and it is certainly that the parasitoids is widely distributed in China （expect Xinjiang）, of course the articles and specimens are collected in seven provinces of central, West-South of China, Jiangxi, Hubei, Shanxi, Sichun, Yunan, Guizhou and Taiwan in China. After compare with species of S. szaboi from Renhuai and SEM photographs of S. szaboi from India, it is very probable that in the world geographical range of the parasitoid, Syntretomorphy szaboi extends to northern India through import oriential honey bees or nature extension from Western China. Is the conclusion true, there is a need of a experiment of molecular phylogenetic studies of Syntretomorpha szaboi in two countries.
