Imidacloprid Alters Foraging and Decreases Bee Avoidance of Predators

Imidacloprid Alters Foraging and Decreases Bee Avoidance of Predators

Concern is growing over the effects of neonicotinoid pesticides, which can impair honey bee cognition. We provide the first demonstration that sublethal concentrations of imidacloprid can harm honey bee decision-making about danger by significantly increasing the probability of a bee visiting a dangerous food source. Apis cerana is a native bee that is an important pollinator of agricultural cr...

Abnormal foraging behavior induced by sublethal dosage of imidacloprid in the honey bee (Hymenoptera: Apidae).

Although sublethal dosages of insecticide to nontarget insects have never been an important issue, they are attracting more and more attention lately. It has been demonstrated that low dosages of the neonicotinoid insecticide imidacloprid may affect honey bee, Apis mellifera L., behavior. In this article, the foraging behavior of the honey bee workers was investigated to show the effects of imi...

Foraging Ecology of the Bee

Ann. Entomol. Soc. Am. 81(3): 419-427 (1988) ABSTRACT The anthophorid bee, Hahropoda (=Emphoropsis [R. W. Brooks, personal communication]) laboriosa (F.), is a locally abundant, vernal, univoltine species. It flies from February through April in Georgia and Alabama. In these states, females are oligolectic on Vaccinium spp., particularly V. ashei Reade and V. corymbosum L., with Gelsemium sempe...

Foraging Biology of Neglected Bee Pollinators

Genetic determinants of honey bee foraging behaviour

The amount of pollen stored in honey bee, Apis mellifera, colonies is a selectable trait. Five generations of two-way selection resulted in high and low strains that differed more than six-fold in quantities of stored pollen. Comparisons with hybrid crosses suggested that colony-level, high pollen-hoarding behaviour is inherited as a recessive trait. Colony levels of stored honey, however, show...
