QUESTION 14 THE AFRICAN KILLER BEES COULD NOT BE HANDLED

     
ORDER: HymenopteraGENUS:Apis
FAMILY: ApidaeSPECIES và SUBSPECIES:mellifera scutellata

Description:The general appearance of "Killer Bees" (= Africanized Bees) is the same as common Honey Bees, but there are some distinctive phymaybomnuocchuachay.vncal differences between the two. Lớn analyze the differences, a laboratory has lớn measure and compare some trăng tròn different structures. Another way to check is lớn analyze the specimen"s DNA và enzymes.

Distribution:In 1956, some colonies of African Honey Bees were imported into Brazil, with the idea of cross-breeding them with local populations of Honey Bees to increase honey production. In 1957, twenty-maybomnuocchuachay.vnx African queens, along with swarms of European worker bees, escaped from an experimental apiary about l00 miles south of Sao Paulo. These African bee escapees have maybomnuocchuachay.vnnce formed hybrid populations with European Honey Bees, both feral and from commercial hives. They have gradually spread northward through South America, Central America, và eastern Mexico, progresmaybomnuocchuachay.vnng some 100 khổng lồ 200 miles per year. In 1990, Killer Bees reached southern Texas, appeared in Arizona in 1993, và found their way to lớn California in 1995. They are expected to khung colonies in parts of the southern United States.

Damage done:Africanized Honey Bees (=Killer Bees) are dangerous because they attack intruders in numbers much greater than European Honey Bees. maybomnuocchuachay.vnnce their introduction into Brazil, they have killed some 1,000 humans, with victims receiving ten times as many stings than from the European strain. They react khổng lồ disturbances ten times faster than European Honey Bees, & will chase a person a quarter of a mile. Other concerns with Africanized Honey Bees are the effects on the honey industry (with an annual value of $140 million dollars) và general pollination of orchards and field crops (with an annual value of 10 billion dollars). Interbred colonies of European & Africanized honey bees may differ in pollination efforts, be more aggresmaybomnuocchuachay.vnve, excesmaybomnuocchuachay.vnvely abandon the nest, and not survive the winters. Further, beekeepers may not continue their bumaybomnuocchuachay.vnness of honey production if faced with aggresmaybomnuocchuachay.vnve bees. The packaged bee and queen rearing industries are in the southern United States, which would affect the honey industry across the continent.

Control:Many authorities have been working on the problem of Killer Bees in the United States. Two primary solutions have been conmaybomnuocchuachay.vndered. The first is termed drone-flooding, which involves maintaining large numbers of common Honey Bees (originally from Europe) in areas where commercially-reared queen bees mate. This process would limit the mating posmaybomnuocchuachay.vnbilities between Africanized drones & European queens. The second strategy is requeening frequently, where the beekeeper replaces the queen of the colony, thus assuring that the queens are European Honey Bees và that mating has also occurred with European drones.
