When vespine wasps, Vespa velutina Lepeletier (Hymenoptera: Vespidae), hawk (capture) bees at their nest entrances alerted and poised guards of Apis cerana cerana F. and Apis mellifera ligustica Spinola (Hymenoptera: Apidae) have average thoracic temperatures slightly above 24° C. Many additional worker bees of A. cerana, but not A. mellifera, are recruited to augment the guard bee cohort and b...

In swarming season, honeybee queens emit two kinds of queen piping signals: tooting and quacking. These signals are considered to be important for swarming, honeybees distinguish between the through differences in their temporal structures. this study, we revealed that species, Apis cerana mellifera, had different The A. consisted almost one long syllable, while mellifera was constructed from s...

Apis mellifera intermissa is the native honeybee subspecies of Algeria. A. m. intermissa occurs in Tunisia, Algeria and Morocco, between the Atlas and the Mediterranean and Atlantic coasts. This bee is very important due to its high ability to adapt to great variations in climatic conditions and due to its preferable cleaning behavior. Here we report the draft genome sequence of this honey bee,...

Precocene II, Anti-Juvenile Hormone, Honey Bee, Apis mellifera, Anti-Feedant The effect of precocene II on development of the honey bee, Apis mellifera, was studied in vitro. Oneto two-day-old worker larvae (body weight 0.5 — 1.0 mg) were removed from the colonies, reared on royal jelly-yeast extract, and after 24 h were topically applied with different amounts (5 75 |ig/larva) of precocene II....

Ants, like honeybees, can set their travel direction along foraging routes using just the surrounding visual panorama. This ability gives us a way to explore how visual scenes are perceived. By training wood ants to follow a path in an artificial scene and then examining their path within transformed scenes, we identify several perceptual operations that contribute to the ants' choice of direct...

Systemic pesticides, including the widely used neonicotinoids, have been linked to colony losses in honeybees and declines in other pollinator species. More recently, evidence has accumulated suggesting that their widespread, often prophylactic use is harming important parts of soil and water ecosystems, putting biodiversity and ecosystem services at risk. Michael Gross reports. Systemic pestic...

A key issue for theories of perception is specifying the primitives used by the visual system to isolate and identify the objects in an image. Although local features are typically suggested, there is good reason to look for global, configural features as primitives too. Chen et al.'s specific proposal of topological features is both explicit and capable of capturing important global informatio...

Honeybees have small brains, but their behavioural repertoire is impressive. In this article we focus on the extent to which adaptive behaviour in honeybees exceeds elementary forms of learning. We use the concept of modularity of cognitive functions to characterize levels of complexity in the honeybee brain. We show that behavioural complexity in the honeybee cannot be explained by independent...

INTRODUCTION This study aimed to investigate the occurrence of Africanized honeybees in Botucatu, São Paulo, Brazil, and to implement a program to remove such swarms. METHODS The occurrences of Africanized honeybee swarms between 2010 and 2012 were studied and strategies to prevent accidents were developed. RESULTS We noted 1,164 cases of Africanized honeybee occurrences in the city, and 42...
