Diana Sammataro and Alphonse Avitabile have revised and expanded their clear and comprehensive guide to cover changes in beekeeping. They discuss the crisis created by the parasitic bee mites. In less than a decade, for example, Varroa mites have saturated the North American honeybee population with disastrous results, devastating both managed and wild populations. The new edition of The Beekeeper's Handbook covers mite detection and control as well as the selection and testing of bees that may have some tolerance to mites.
