Salt preferences of honey bee water foragers.
The importance of dietary salt may explain why bees are often observed collecting brackish water, a habit that may expose them to harmful xenobiotics. However, the individual salt preferences of water-collecting bees were not known. We measured the proboscis extension reflex (PER) response of Apis mellifera water foragers to 0-10% w/w solutions of Na, Mg and K, ions that provide essential nutri...
متن کاملBumble-bee foragers infected by a gut parasite have an impaired ability to utilize floral information.
Parasitic infection can influence a variety of behavioural mechanisms in animals, but little is known about the effects of infection on the cognitive processes underlying ecologically relevant behaviours. Here, we examined whether parasitic infection alters cognitive aspects of foraging in a social insect, the bumble-bee (Bombus impatiens). In controlled experiments, we assessed the ability of ...
متن کاملEffects of some insecticides on longevity of the foragers honey bee worker of local honey bee race Apis mellifera jemenatica.
INTRODUCTION Honeybees are constantly exposed to a wide range of vital and non-vital pressures that may interact with each other and affect the health or survival of the insects. Pesticides are the main danger for the insects, and they subsequently have impacts on human and environmental health. METHODS Field research was conducted in the apiary of Hada Al Sham Research Station, where the wor...
متن کاملEffects of honey bee (Hymenoptera: Apidae) and bumble bee (Hymenoptera: Apidae) presence on cranberry (Ericales: Ericaceae) pollination.
Honey bees, Apis mellifera L., are frequently used to pollinate commercial cranberries, Vaccinium macrocarpon Ait., but information is lacking on the relative contribution of honey bees and native bees, the effects of surrounding vegetation on bee visitation, and on optimal timing for honey bee introduction. We begin with a descriptive study of numbers of honey bees, bumble bees, and other bees...
متن کاملIndividual honey bee (Apis cerana) foragers adjust their fuel load to match variability in forage reward
Animals may adjust their behavior according to their perception of risk. Here we show that free-flying honey bee (Apis cerana) foragers mitigate the risk of starvation in the field when foraging on a food source that offers variable rewards by carrying more 'fuel' food on their outward journey. We trained foragers to a feeder located 1.2 km from each of four colonies. On average foragers carrie...
