Paenibacillus larvae is a highly contagious and often lethal widely distributed pathogen of honeybees, Apis mellifera but has not been reported in eastern Africa to date. We investigated the presence of P. larvae in the eastern and western highland agro-ecological zones of Uganda by collecting brood and honey samples from 67 honeybee colonies in two sampling occasions and cultivated them for P....

There is growing concern about declines in pollinator species, and more recently reservations have been expressed about mismatch in plant-pollinator synchrony as a consequence of phenological change caused by rising temperatures. Long-term changes in honeybee Apis mellifera phenology may have major consequences for agriculture, especially the pollinator market, as well as for honey production. ...

The honeybee pathogens Nosema ceranae and deformed wing virus (DWV) cause the collapse of honeybee colonies. Therefore, it is plausible that these two pathogens act synergistically to increase colony losses, since N.ceranae causes damage to the mid-gut epithelial ventricular cells and actively suppresses the honeybees' immune response, either of which could increase the virulence of viral patho...

Bee keeping is indispensable to global food production. It is an alternate income source, especially in rural underdeveloped African settlements, and an important forest conservation incentive. However, dwindling honeybee colonies around the world are attributed to pests and diseases whose spatial distribution and influences are not well established. In this study, we used remotely sensed data ...

in order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in isfahan region. protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and pollen. results showed that the longevi...

Honeybee losses are an extensive global problem. In this study, a new compartment model of honeybee population that mainly concerns honey production is developed. The describes the interaction food stock with brood (immature bees), adult bees and produced honey. present paper, issue adequate recovery addressed parameter identification inverse problem solved. An adjoint equation procedure to obt...

grooming behaviour is one of the important mechanisms of honeybee defence against parasitic mites. in addition to genetical characteristics, environmental conditions affect the behavioural traits of honeybee colonies. the main objective of this study was to examine the effect of temperature and humidity on the ability of honeybee workers to remove varroa mites from their body. one hundred worke...

background : nosemosis of european honey bee (apis mellifera ) is present in bee colonies world­wide. until recently, nosema apis had been regarded as the causative agent of the disease, that causes heavy economic losses in apicultures. nosema ceranae is an emerging microsporidian para­site of european honeybees, a. mellifera , but its distribution is not well known. previously, nosemosis in ho...
