Do So

While it is generally accepted that honeybees ( Apis mellifera ) are capable of using the pattern of polarized light in the sky to navigate to a food source, there is little or no direct behavioural evidence that they actually do so. We have examined whether bees can be trained to find their way through a maze composed of four interconnected tunnels, by using directional information provided by polarized light illumination from the ceilings of the tunnels. The results show that bees can learn this task, thus demonstrating directly, and for the first time, that bees are indeed capable of using the polarized-light information in the sky as a compass to steer their way to a food source.

Drone brood of Apis mellifera is often removed from the beehive to control the honeybee parasite Varroa destructor. Instead of discarding the drone brood, it could rather be used as a new food source for human nutrition. However, studies on microbiological hazards caused by edible insects are rare, especially in the case of drone brood. In this survey, microbial total viable cell counts and the most common foodborne bacteria were assessed in raw drone brood. Samples were taken from 24 beehives from four apiaries in Switzerland. The drone brood combs were harvested either by the beekeepers with their personal equipment or by the researchers with sterile equipment. No difference in the total viable cell counts was found between these two methods. All samples were free of Salmonella. Viable counts of Bacillus cereus, coagulase-positive staphylococci, Enterobacteriaceae and Escherichia coli were all below the detection limits of the recommended ISO reference methods. However, Listeria monocytogenes was detected in eight samples (all <10 cfu/g), which has not been reported in edible insects until now.

Honeybee waggle dance: recruitment success depends on the dance floor

Recruitment Success

The waggle dance of the honeybee Apis mellifera, used to recruit nestmates to a food source, takes place on the surface of the combs in the dark hive. The mechanism of information transfer between dancer and follower bees is not entirely understood. The results presented here reveal a novel factor that must be brought into any consideration of this mechanism, namely that the nature of the floor on which the bees dance has a considerable influence on the recruitment of nestmates to a food source. Dancers on combs with open empty cells recruit three times as many nestmates to a food source as dancers on capped brood cells.

The extensive use of plant protection products in agricultural practice and obtaining high and top quality yields results in decline of a major part of the natural regulators and the insects-pollinators. The reduction in their numbers in agricultural areas poses a threat for the pollination of entomophilous plants on global scale. The objective of this study was to establish areas of flowering varieties of grass mixes, ensuring proper habitats and food source for the pollinators of agricultural crops. The tests showed that the plant varieties in the grass mixes blossomed in the period April to June (1.5-2 months), providing varying species of pollinators, depending on the plants species. In the different-coloured layers of the grass mixtures: white, purple and yellow, the following pollinators were determined: Apis mellifera L., Megachile sp., Halictus scabiosae Rossi, Lasioglossum xanthopus Kirby, Melita leporita, Andrena flavipes Panzer., Macropis europaeae Warn., Anthidium manicatum L., Ceratina cucurbitina Rossi and Ceratina sp.

Abstract Gilead et al. present a rich account of abstraction. Though the account describes several elements which influence mental representation, it is worth also delineating how feelings, such as fluency and emotion, influence mental simulation. Additionally, though past experience can sometimes make simulations more accurate and worthwhile (as Gilead et al. suggest), many systematic prediction errors persist despite substantial experience.
