Résumé : |
A review of references on Acarapis woodi (Rennie) indicated that this acarapis mite is not as serious as has generally been stated in American beekeeping literature. It is not considered to be the cause of Isle of Wight disease of bees. The quarantine against the importation of honey bees into the United States, except from Canada, is based on the probable effect this pest might have on the beekeeping industry.
The rediscovery of an external acarapis mite in the United States in 1959, raised the question as to the actual relationship of acarapis mites to bees. The two external mites, Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler were subsequently found to be widely scattered in Canada and the United States without any visible symptoms of injury to the bees. It is concluded that they must have been present for many years before any quarantine was levied. The external mites can be distinguished from A. woodi by morphological as well as ecological characters. No evidence of A. woodi was found, and none has ever been reported from either the United States or Canada. The lengths of the developmental periods and the number of forms per individual bee infested were studied. Data indicate that both acarapis mites are more attracted by young hive bees than by the older field bees. All stages of development were found throughout the year. |
