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。 Apis mellifera, a western bee pollen from Guangzhou, is doubly endangered by Varroa jacobsoni and Tropilaelapsclareae. The bee colony is parasitized by large bee mites all the year round. The parasitoids of the large bee mites are low, At about 5%, while the small bugs mites harm more serious, the summer and autumn are the serious hazards of the small bugs mites, nest parasitism rate up to 67.56%, the nest parasitism density of 2.98 mites / room. The changes of the growth and development of large and small bee mites are closely related to their host bee colonies and vary with the host swarm potential.
