The tendency of honey bees, Apis mellifera L, to become infested with tracheal mites, Acarapis woodi (Rennie), was measured in six different types of F1 colonies. The colonies were produced by mating a stock (Buckfast) known to resist mite infestation to each of five commercially available stocks and to a stock known to be susceptible to mites. Young uninfested bees from progeny and parent colonies were simultaneously exposed to mites in infested colonies, then retrieved and dissected to determine resultant mite infestations. Reduced infestations similar to but numerically greater than those of the resistant parent bees occurred in each of the six crosses made with resistant bees regardless of the relative susceptibility of the other parental stock. Reciprocal crosses between resistant and susceptible queens and drones proved equally effective in improving resistance. Therefore, allowing resistant stock queens to mate naturally with unselected drones, or nonresistant queens to mate with drones produced by pure or outcrossed resistant queens, can be used for improving resistance of production queens.
在六种不同类型的F1蜂群中，对意大利蜜蜂（Apis mellifera L.）感染气管螨（Acarapis woodi (Rennie)）的倾向进行了测定。这些蜂群是通过将已知抗螨的一个蜂种（巴克法斯特蜂种）与五个市售蜂种以及一个已知易感螨的蜂种进行交配产生的。来自子代蜂群和亲代蜂群的未受感染的幼蜂同时在受螨感染的蜂群中接触螨，然后取回并解剖以确定由此产生的螨感染情况。与抗性亲代蜜蜂相比，感染率降低，虽情况相似但数量更多，在与抗性蜜蜂进行的六个杂交组合中的每一个中均出现，而不论另一亲本蜂种的相对易感性如何。抗性蜂王和雄蜂与易感蜂王和雄蜂之间的正反交在提高抗性方面同样有效。因此，让抗性蜂种的蜂王与未经选择的雄蜂自然交配，或者让非抗性蜂王与由纯种或杂交抗性蜂王产生的雄蜂交配，可用于提高生产蜂王的抗性。
