Floral specificity is a behavior that evolved due to mutualistic interactions between the plant-pollinator community. Flowers advertise themselves using visual or chemical cues attract pollinators and gain reproductive success through pollination. Pollinators forage for rewards such as nectar pollen produced by flowers. We found an anthophorid bee, Tetralonia macroceps, foraged specifically on ...

Each region has its own floristic characteristics relative to geographical position. The specificity of the vegetation and particularities each flora require knowledge beekeeping determine forage supply for bees. Where, production in Fray Mamerto Esquiú department (Catamarca, Argentina) is based on diversity plant species place, composed native flora, natural forest different types crops (forag...

Say the word “insect” and what comes to mind? I asked that question to nonentomology, first-year undergraduate students on the first day of class. The typical response: “Insects suck.” I suspect they were thinking of the suffering inflicted by mosquitoes and other bloodfeeding insects, crop damage caused by their vegetarian counterparts, and the invasion of human dwellings by cockroaches and te...

Abstract Colletes hederae, the ivy bee, (Hymenoptera: Colletidae) has undergone large range expansions in Europe recent years, including colonising Britain 2001 with its original distribution limited to Western mainland and Channel Islands. It is thought specialise on Hedera helix L. (Apiales: Ariliaceae), common ivy. However, some research questioned this dependence. This study quantifies fora...

Abstract Stachys annua (L.) L., a melliferous archaeophyte plant became dominant weed of the cereal stubbles Carpathian Basin in medieval three-field system. By middle nineteenth century, this provided more than two-thirds Hungarian honey production, and its high quality monofloral turned into characteristic brand apiculture. Recognizing importance, S. also briefly minor crop cultivated “bee ga...

A recurrent concern in nature conservation is the potential competition for forage plants between wild bees and managed honey bees. Specifically, that highly sophisticated system of recruitment large perennial colonies quickly exhaust resources leading to local extirpation However, different species show preferences plants. We here summarize known bee at national scale Denmark. Our focus on flo...

Nectar-related traits influence the number of bee visits to sunflowers, but effects floret size on diversity and composition communities are unknown. In 4 year × planting date combinations, bees were collected from sunflowers with small (< 7.5 mm), medium (7.5–9 or large (> 9 mm) florets, counts foraging used clarify responses plant traits. No effect was found, associations tongue length led di...

To investigate the value of atypical foraging behavior honey bees (Apis mellifera) during dearth, we compared number days survived in vitro among young adult kept hoarding cages using various feeding strategies. Treatment groups were fed solid patty diets consisting 100%, 67%, or 33% bee gathered corn grain dust, hand collected 100% commercially available pollen substitute. The also provided ei...
