reduce the frequency of pathogen spillover to wild bee communities because these measures would decrease the risk of transmission. Additionally, the increased use of native bees and habitat restoration could reduce the risk of pathogen spillover from honey bees to wild bees. Studies focussing on the...

Nosema ceranae infection is ubiquitous in western honey bees, Apis mellifera, in the United States and the pathogen has apparently replaced Nosema apis in colonies nationwide. Displacement of N. apis suggests that N. ceranae has competitive advantages but N. ceranae was significantly less infective...
All social bees and wasps use their stinger to defend the colony. The sting consists of a venom reservoir and three “needles”: two lancets (sometimes barbed) and a stylet, linked together to form a hollow tube through which venom can be pumped. The stylet makes the initial penetration, ...
They hunt bees Belgian Canary The Belgian canary is one of the oldest and most influential in its genus. Belgian Malinois Mix These Belgian Malinois mixes can be scary when they are threatened. But it's important to note that they know when aggression is necessary. In other words, they will...
The stock of honey bees in the northern neotropics is likely a composite of European and African lineages, but the genetic makeup of most populations in this region has remained unstudied. We analyzed the genetic composition of honey bees across temperate and tropical regions of Mexico using mitoc...
Caterpillars of many hairstreaks and blues possess honeydew glands. Ants milk these caterpillars and in return, protect them from predators.Gossamer wing coloring comes from two different types of scales: gray, brown and orange scales are pigmented, while blue, green, purple and copper colors ...
F Puerta,JM Flores - 《American Bee Journal》 被引量: 44发表: 1982年 Genetic Variation in Virulence among Chalkbrood Strains Infecting Honeybees Ascosphaera apis causes chalkbrood in honeybees, a chronic disease that reduces the number of viable offspring in the nest. Although lethal for larvae...
The skunk likes honey (and bees): stings do not appear to bother it! Puma The puma is also called the cougar or the mountain lion. From a standing start, the puma is able to jump as high as 5 metres. Bald Eagle The bald eagle lives on the waterside and feeds mainly on fish. ...
The Problem with North American Honey Honey that is produced in the U.S. and Canada is mostly a by-product of professional beekeepers who make their primary income from leasing out their bees to pollinate crops in commercial agriculture. ...
