Varroa destructor is among the greatest biological threats to western honey bee (Apis
mellifera L.) health worldwide. Beekeepers routinely use chemical treatments to control this …

Very rapidly after Varroa destructor invaded apiaries of Apis mellifera, the devastating effect
of this mite prompted an active research effort to understand and control this parasite. Over a …

This paper covers measures of field colony strength, by which we mean population
measures of adult bees and brood. There are generally two contexts in which an investigator …

Since 2006, disastrous colony losses have been reported in Europe and North America. The
causes of the losses were not readily apparent and have been attributed to overwintering …

The collapse of the ubiquitous honey bee population during the past 20 years has caused a
pollination vacuum for many crops. Surveys and grower experience indicate that a crisis …

The relative effect of parasite levels, bee population size, and food reserves on winter
mortality and post winter populations of honey bee colonies was estimated. More than 400 …

▪ Abstract The hive of the honey bee is a suitable habitat for diverse mites (Acari), including
nonparasitic, omnivorous, and pollen-feeding species, and parasites. The biology and …

Summary 1 The ecto‐parasitic mite Varroa destructor is a serious world‐wide pest of the
honeybee Apis mellifera and has being linked with the death of millions of colonies …

In East Africa, honey bees (Apis mellifera) provide critical pollination services and income for
small-holder farmers and rural families. While honey bee populations in North America and …

Background Recent elevated winter loss of honey bee colonies is a major concern. The
presence of the mite Varroa destructor in colonies places an important pressure on bee …
