The Effects of Pesticides on Queen Rearing and Virus Titers in Honey Bees (Apis mellifera L.)
The effects of sublethal pesticide exposure on queen emergence and virus titers were examined. Queen rearing colonies were fed pollen with chlorpyrifos (CPF) alone (pollen-1) and with CPF and the fungicide Pristine(®) (pollen-2). Fewer queens emerged when larvae from open foraging (i.e., outside) colonies were reared in colonies fed pollen-1 or 2 compared with when those larvae were reared in o...
متن کاملRearing Honey Bees, Apis mellifera, in vitro 1: Effects of Sugar Concentrations on Survival and Development
A new method for rearing honey bees, Apis mellifera L. (Hymenoptera: Apidae), in vitro was developed and the effects of sugar concentrations on survival and development were studied. Seven different glucose (G) and fructose (F) compositions (0%G+0%F, 3%G+3%F, 6%G+6%F, 12%G+12%F, 0%G+12%F, 12%G+0%F, and 4%G+8%F) were tested. Larvae were able to grow to the post defecation stage without addition ...
متن کاملExperimental evaluation of the reproductive quality of Africanized queen bees (Apis mellifera) on the basis of body weight at emergence.
There has been much speculation about which phenotypic traits serve as reliable indicators of productivity in queen honeybees (Apis mellifera). To investigate the predictive value of queen body weight on colony development and quality, we compared colonies in which queens weighed less than 180 mg to those in which queens weighed more than 200 mg. Both groups contained naturally mated and instru...
متن کاملComparison of acute effects of heroin and Kerack on sensory and motor activity of honey bees (Apis mellifera)
Objective(s):Previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. The aim of the present study was to compare the effects of heroin and Iranian street Kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. Materials and Methods: All drugs were given orally to honey bees 30 min before each exper...
متن کاملParasite Pressures on Feral Honey Bees (Apis mellifera sp.)
Feral honey bee populations have been reported to be in decline due to the spread of Varroa destructor, an ectoparasitic mite that when left uncontrolled leads to virus build-up and colony death. While pests and diseases are known causes of large-scale managed honey bee colony losses, no studies to date have considered the wider pathogen burden in feral colonies, primarily due to the difficulty...
