The areas of wild land around the edges of agricultural fields are a vital resource for many species. These include insect pollinators, to whom field margins provide both nest sites and important resources (especially when adjacent crops are not in flower). Nesting pollinators travel relatively short distances from the nest to forage: most species of bee are known to travel less than two kilome...

Many ant species and some social bees display size-related polyethism, often referred to as alloethism (Wilson, 1971). For example bumblebees (Bombus spp.) exhibit alloethism; there is great size variation within the worker caste, and large bees tend to be foragers, while smaller bees tend to perform within-nest tasks (reviewed in Goulson, 2003). In contrast, honeybees workers are approximately...

Hygienic behavior in honey bees is a behavioral mechanism of disease resistance. Bees bred for hygienic behavior exhibit an increased olfactory sensitivity to odors of diseased brood, which is most likely differentially enhanced in the hygienic line by the modulatory effects of octopamine (OA), a noradrenaline-like neuromodulator. Here, we addressed whether the hygienic behavioral state is link...

Honeybees coordinate foraging efforts across vast areas through a complex system of advertising and recruitment. One mechanism for coordination is the waggle dance, a movement pattern which carries positional information about food sources. However, recent evidence suggests that recruited foragers may not use the dance’s positional information to the degree that has traditionally been believed....

Bees often facilitate pollination of important greenhouse crops. Individual bumblebees Bombus terrestris were therefore tested in an indoor flight arena to evaluate whether or not search time to find flowers was influenced by the inclusion or exclusion of ultraviolet radiation. Plastic model flowers of similar spectral properties to flowers of tomato Lycopersicon esculentum Mill. were used to e...

Ethobotanical information were collected on 97 plant species from Ranyal Hills District Shangla, Pakistan. These plants were classified for their traditional medicinal and economic uses. Many of these plants have more than one local use. There were 37 fuel species, 37 forage/fodder species, 31 medicinal species, 18 edible species, 12 species used for making shelter, 10 vegetables species, 9 poi...

The deposition of antimicrobial plant resins in honey bee, Apis mellifera, nests has important physiological benefits. Resin foraging is difficult to approach experimentally because resin composition is highly variable among and between plant families, the environmental and plant-genotypic effects on resins are unknown, and resin foragers are relatively rare and often forage in unobservable tre...

Insect pollinators such as bumblebees play a vital role in many ecosystems, so it is important to understand their foraging movements on a landscape scale. We used harmonic radar to record the natural foraging behaviour of Bombus terrestris audax workers over their entire foraging career. Every flight ever made outside the nest by four foragers was recorded. Our data reveal where the bees flew ...

Between March and May 2022, researchers conducted a broad survey in the Lamjung district to ascertain presence accessibility of bee-friendly flora compile floral calendar. In PMAMP Bee Zone, 62 respondents were chosen for interview through simple random sampling approach, from pool 382 registered beekeepers. Primary data collection involved using personal interviews, focus group discussions, ke...

Trachypus Klug is a Neotropical genus of crabronid wasps comprising 31 ground-nesting species. Its species can be solitary or communal, and two diet ranges are known: they forage on several bee subfamilies wasps; specialists stingless bees. Natural history observations scarce nowadays but essential to contextualize ecological evolutionary studies. Here we report new records give biological note...
