摘要
广州地区西方蜜蜂 Apis mellifera 受大蜂螨 Varroa jacobsoni、小蜂螨 Tropilaelapsclareae 的双重危害,蜂群一年四季都有大、小蜂螨寄生,其中大蜂螨的寄生水平较低,巢房寄生率通常在5%左右,而小蜂螨危害比较严重,夏、秋两季是小蜂螨严重危害期,巢房寄生率最高达67.56%,巢房寄生密度达2.98螨/房。大、小蜂螨的消长变化与其寄主蜂群密切相关;随其寄主蜂群群势的变化而变化。
In Guangzhou the Apis mellifera colonies suffered from two cetoparasitic mites,Varroa jacobsoni and Tropilaelaps clareac,Both Varroa jacobsoni and Tropilaelaps clarcae could be found in the colonies all the year round,and the infestation rate of cells by Varroa jacobsoni was quite low with the level of 5%. Tropilaelaps clareae caused more severe damage to the infested colonies than Varroa jucobsoni.In Summer aud Autumn Tropilaelaps clarcac infested the cells of the infested colonies scriousIy and the highest infestation rate of the cells could be as high as 67.65% in average and the highest infestation density was 2.08 mites per cell in average.The population dynamies of the two species of mites was related to the host colonies and varied with the strength of the host colonies.
