Brain-behavioural olfactory asymmetries in Apoidea
… coordination and cooperation. The superfamily Apoidea represents a group in which both the study of the appearance of population-level asymmetries and advantages in individual organisms (e.g., in the A. mellifera model) can be exploited. Here I described a study on olfactory lateralization in a …

Alterações morfológicas dos testículos e vesículas seminais da abelha Plebeia lucii (Hymenoptera: Apoidea: Meliponini), durante a maturação sexual.
A abelha sem ferrão Plebeia lucii foi descrita pelo Prof. Dr. Pe. Jesus Santiago Moure em 2004, a partir de indivíduos de uma colônia coletada em Viçosa, Minas Gerais. Para contribuir com o conhecimento da morfologia e fisiologia do aparelho reprodutor masculino desta espécie os ductos deferentes, …

Toxicity assessment of pesticides and biopesticides on wild and managed bees (Hymenoptera, Apoidea), and richness evaluation in mediterranean and tropical agroecosystems
Bees (Hymenoptera, Apoidea) are the main pollinator insects for wild and cultivated plants, being of crucial environmental and economic importance. Their global decline, driven by anthropogenic factors, including the use of synthetic pesticides, is an alarming concern. Biopesticides can be a viable …

The Pollination Ecology of Four Species of Local Vernal Herbaceous Angiosperms
… syndrome. Short-tongued flies and solitary Apoidea were common pollinators. Erythronium americanum Ker. Also showed a trend towards xenogamy, but pollination was accomplished by large heavy Apoidea. Trillium grandiflorum (Michx.) Salisb. is agamospermic, but not unless abortive tubes are …

The Importance Of Surface Mining As A Landscape Variable In Shaping Wild Bee Communities In Central Appalachian Forests
… in biodiversity. Native bees (Hymenoptera, Apoidea) provide essential pollination services and have been declining in abundance dramatically in recent years. One potential cause of these declines is anthropogenic disturbance. Eleven sites were established in Southeastern Kentucky, U.S.A. …

Floral derived compounds as attractants for agricultural pests in the family Noctuidae
… of beneficial hymenoptera (Syrphidae and Apoidea) were significantly reduced. Taken together, the current findings provide insights into how Noctuid moths interact with host odour cues and how they may be used in developing pest management techniques.

Wild bee responses to land use change: investigating the role of bee body size
… species and populations. Wild bees (Hymenoptera: Apoidea) are essential pollinators for many wild and cultivated flowering plants, and exhibit marked differences in life history traits. The consequences of land use change may therefore affect wild bees differently, but this remains poorly …

The Bees of Two Sites in the Big Thicket National Preserve, Texas, with a Consideration of the Effects of a Rare Flooding Event
<p>Native bees are an important part of terrestrial ecosystems due to their coevolution with flowering plants. This study catalogued the bee fauna of two sandyland sites in the Big Thicket National Preserve and assessed whether a community was impacted by a historic hurricane-induced flooding …
