Africanized bees extend their distribution in California
Africanized honey bees (Apis mellifera) arrived in the western hemisphere in the 1950s and quickly spread north reaching California in the 1990s. These bees are highly defensive and somewhat more difficult to manage for commercial purposes than the European honey bees traditionally kept. The arrival of these bees and their potentially replacing European bees over much of the state is thus of gr...
متن کاملRange and Frequency of Africanized Honey Bees in California (USA)
Africanized honey bees entered California in 1994 but few accounts of their northward expansion or their frequency relative to European honey bees have been published. We used mitochondrial markers and morphometric analyses to determine the prevalence of Africanized honeybees in San Diego County and their current northward progress in California west of the Sierra Nevada crest. The northernmost...
متن کاملDisease Resistance in Africanized Honey Bees
One of the consequences of the expansion is the health conditions of the bees in the countries where they are found today. It is known that the honey bees are susceptible to several diseases and bee pests such as EFB, AFB, Nosema, Amoeba, Sacbrood, Chalkbrood, Acarine, Varroosis, Viruses etc. The two most important diseases of honey bees are Varroosis and American Foulbrood (AFB) (DE JONG, 1994...
متن کاملGentle Africanized bees on an oceanic island
Oceanic islands have reduced resources and natural enemies and potentially affect life history traits of arriving organisms. Among the most spectacular invasions in the Western hemisphere is that of the Africanized honeybee. We hypothesized that in the oceanic island Puerto Rico, Africanized bees will exhibit differences from the mainland population such as for defensiveness and other linked tr...
متن کاملInfestation and distribution of the mite Varroa destructor in colonies of Africanized bees.
Whereas in several parts of the world varroa is the major pest affecting apiculture, in others the parasite is unknown to many beekeepers because its damage to bees is minor. The impact of the mite Varroa destructor is related to the climatic conditions and the races of Apis mellifera bees in each region where the pest exists. In the present study, the current level of infestation by the mite w...
