Approximately 87% of flowering plants in the world are pollinated by animals. Bees are some of the most economically and ecologically important pollinators, necessary for the production of about one third of all crops. One such crop is highbush blueberry, grown throughout Rhode Island in small acreages. I conducted a survey of the bee species foraging on managed blueberry farms throughout Rhode...

Humanity has long been fascinated by animals with apparently unfavorable lifestyles [1]. Nesting habits are especially important because they can limit where organisms live, thereby driving population, community, and even ecosystem dynamics [2]. The question arises, then, why bees nest in active termite mounds [3] or on the rim of degassing volcanoes, seemingly preferring such hardship [4]. Her...

Abstract With urbanisation leading to loss of nesting resources, and increasing public interest in helping bees, bee hotels (trap-nests) are becoming popularised. However, their success is relatively understudied. The influence habitat type determining occupancy emergence also poorly known. Over two years across 7 bushland remnant residential garden sites, trap-nests were installed completed ne...

Nests of Centris tarsata Smith, 1874 were obtained from trap-nests in areas of dry semi-deciduous forest (Baixa Grande) and caatinga (Ipirá), in the State of Bahia. Nesting occurred in bamboo canes and in tubes of black cardboard with 5.8 cm (= small tube) and 10.5 cm (= large tube) in length and 0.6 and 0.8 cm in diameter, respectively. In both areas C. tarsata nested during the wet season pro...

Nutmeg leaf, lemongrass, and bee nests contain bioactive compounds that have potential as mosquito repellents. The purpose of this study was to learn about the bioactivity a combination extract nutmeg nests, well determine efficient repellent lotion recipe from extract. maceration process used for extraction. Total flavonoid content estimated by comparing it quercetin. absorbance value measured...

Lasioglossum zephyrum usually lives in small colonies but is facultatively solitary. Lone bees and colonies produced from female pupae of the same generation were established in artificial indoor nests. Both the length of the prereproductive period and the number of cells produced per bee per day decreased with increasing colony size. In most colonies, ovarially and behaviorally recognized cast...

Bumble bees (Bombus Latr.) are primarily a cold temperate group, but a few species live in the hot, moist conditions of tropical rainforest. We describe the external and internal characteristics of a Bombus pullatus Franklin nest from the tropical lowlands of Costa Rica. The nest was a large, conical mound constructed of cut vegetation on the forest floor, similar to nests of the Amazonian bumb...

Foraging behaviors of bumble bee workers have been examined in natural habitats, whereas agricultural landscapes, which can provide insights on ßight distances to fragmented patches of bloom,have received limited attention. Inparticular, informationonworkerßightdistances to crops blooming several months after nests have been established is invaluable. Here, we examined foraging patterns of Bomb...

Trap nests were used to assay species richness, abundance and distribution of cavitynesting insects in California’s Sierra Nevada foothills bordering the Sacramento Valley. Particular focus was placed on the agriculturally significant native bee Osmia lignaria Say, 1836 because of its potential use as a pollinator of local orchard crops. Osmia lignaria and four other species were obtained from ...
