Western honey bee Since workers are not fully sexually developed, they do not mate with drones and thus can only produce haploid (male) offspring. Queens and workers have a modified ovipositor, a stinger, with which they defend the hive. Unlike bees of any other genus and the queens of their own species, the stinger of worker honey bees is barbed. Contrary to popular belief, a bee does not always die soon after stinging; this misconception is based on the fact that a bee will usually die after stinging a human or other mammal. The stinger and its venom sac, with musculature and a
Western honey bee genome mapped. According to scientists who analyzed its genetic code, the honey bee originated in Africa and spread to Europe in two ancient migrations. Scientists have found that genes related to smell outnumber those for taste, and the European honey bee has fewer genes regulating immunity than the fruit fly and the mosquito. The genome sequence also revealed that several groups of genes, particularly those related to circadian rhythm, resembled those of vertebrates more than other insects. Another significant finding from the honey bee genome study, was that the honey bee was the first insect to be discovered with a
