Division of labor among workers is common in insect societies and is thought to be important in their ecological success. In most species, division of labor is based on age (temporal castes), but workers in some ants and termites show morphological specialization for particular tasks (physical castes). Large-headed soldier ants and termites are well-known examples of this specialization. Howeve...

We examined the antibacterial activities of several types of propolis, including Africanized honey bee green propolis and propolis produced by meliponini bees. The antibacterial activity of green propolis against Micrococcus luteus and Staphylococcus aureus was superior to that of Melipona quadrifasciata and Scaptotrigona sp propolis. Only two samples of propolis (green propolis and Scaptotrigo...

The alfalfa leafcutting bee (ALCB), Megachile rotundata F. (Megachildae), was accidentally introduced into the United States by the 1940s. Nest management of this Eurasian nonsocial pollinator transformed the alfalfa seed industry in North America, tripling seed production. The most common ALCB management practice is the loose cell system, in which cocooned bees are removed from nesting cavitie...

Systropha is a small genus of bees belonging to Rophitinae (sister-group to all remaining Halictidae). Three subgenera are recognized in Systropha: Austrosystropha and Systrophidia that are sub-Saharan endemics, and Systropha s.str., which occurs in Africa and Eurasia. As a result of the rarity of Systropha specimens in collections and the difficulty in associating males and females due to sexu...

BACKGROUND Learning of arbitrary relations is the capacity to acquire knowledge about associations between events or stimuli that do not share any similarities, and use this knowledge to make behavioural choices. This capacity is well documented in humans and vertebrates, and there is some evidence it exists in the honeybee (Apis mellifera). However, little is known about whether the ability fo...

Ovarian cancer is considered to be one of the most important causes of death among women. Cisplatin is one of the oldest chemotherapeutical compounds used for treating ovarian cancer. Previous studies have shown the inhibitory effects of bee venom on certain types of cancer. The aim of the present study was to evaluate the cytotoxic effect of bee venom alone and its synergistic cytological effe...

Inward-rectifier K(+) (Kir) channels play many important biological roles and are emerging as important therapeutic targets. Subtype-specific inhibitors would be useful tools for studying the channels' physiological functions. Unfortunately, available K(+) channel inhibitors generally lack the necessary specificity for their reliable use as pharmacological tools to dissect the various kinds of ...
