熊蜂气管内寄生螨布赫纳蝗螨的生物学特性观察

对新疆与河北地区野生明亮熊蜂及小峰熊蜂蜂王内寄生螨布赫纳蝗螨Locustacarus buchneri的生物学特性进行了初步观察。结果表明： 该螨对两种熊蜂的寄生率分别为10.43%和8.3%，寄生部位为气管与气囊。室内饲养至30天的蜂王体内寄生螨量明显高于饲养至60天的蜂王。未被螨寄生的蜂王与被寄生者比较，前者体重显著高于后者，但二者间产卵始期、产卵率、食卵率和存活率差异不显著。

Biological characteristics of the tracheal mite Locustacarus buchneri of bumblebees in China

The biological characteristics of the endoparasitic mite, Locustacarus buchneri, of bumblebees Bombus lucorum and B. hypocrita in Xinjiang and Hebei were observed. The results showed that the ratio of parasitism in B. lucorum and B. hypocrita were 10.43% and 8.3%, respectively. The parasitic position for the mite was the trachea and air sac of the host. The mite population in the queen reared for 30 d was higher than that in the queen reared for 60 d. The average weight of the unparasitized queen was obviously higher than that of the parasitized queen, while there is no difference in the first date of oviposition and the rates of oviposition, oophagy and survival between the queens unparasitized and those parasitized.
