Polarized iridescence of the tropical carpenter bee, Xylocopa latipes

Journal of Comparative Physiology A, 2022
AbstractThe tropical carpenter bee, Xylocopa latipes, has metallic-reflecting, iridescent wings. The wing reflectance spectra for TE- and TM-polarized light depend on the angle of light incidence in a way characteristic for dielectric multilayers. Anatomy indicates the presence of melanin multilayers in the wing’s chitinous matrix.

Pollinator cultivar choice: An assessment of season-long pollinator visitation among coreopsis, aster, and salvia cultivars

Frontiers in Sustainable Cities, 2022
Documented pollinator declines have encouraged the installation of pollinator plantings in residential, commercial and agricultural settings. Pollinator visitation among cultivars of coreopsis, salvia and asters was compared on 40 dates in a 2-year study

Do French beans (Phaseolus vulgaris L.) grown in proximity to Mt Kenya forest- Kenya- experience pollination deficit?

Journal of Pollination Ecology, 2014
Yields of commercially important crops in Kenya are often far below their potential. Amongst the possible reasons for such low yields may be the ecosystem degradation that can be expected to have negative impacts on pollinator presence in cropland, and ...

Ninhos racionais para mamangava (Xylocopa frontalis) na polinização do maracujá-amarelo (Passiflora edulis) Rational nesting box to carpenter bees (Xylocopa frontalis) in the pollination of passionfruit (Passiflora edulis)

Ciência Rural, 2003
O Brasil é o maior produtor mundial de maracujá-amarelo (Passiflora edulis), porém apresenta baixas produtividades devido à carência de polinizadores naturais, como as abelhas mamangavas (Xylocopa spp.), nas áreas cultivadas.

Low heat tolerance and high desiccation resistance in nocturnal bees and the implications for nocturnal pollination under climate change

Scientific Reports, 2023
Predicting insect responses to climate change is essential for preserving ecosystem services and biodiversity. Due to high daytime temperatures and low humidity levels, nocturnal insects are expected to have lower heat and desiccation tolerance compared ...

First report on pollinating behavior of the small carpenter bee Ceratina ridleyi Cockerell (Hymenoptera, Apidae) in Globba leucantha var. bicolor Holttum (Zingiberaceae) [PDF]

Journal of Hymenoptera Research, 2022
Small carpenter bees of the genus Ceratina are widespread, but little-studied as pollinators despite their presence in various pollinator assemblages. This study documents the importance of Ceratina ridleyi as a pollinator of the small-flowered Malaysian

Honey bees rob flowers after observing conspecifics and carpenter bees

, 2023
Abstract Individuals may add to their behavioural repertoire by observing conspecifics, and possibly heterospecifics. Here we test Darwin’s intriguing hypothesis that honey bees rob nectar from flowers after observing the behaviour of other bees.

The effects of urban land use gradients on wild bee microbiomes

Frontiers in Microbiology, 2022
Bees and their microbes interact in complex networks in which bees form symbiotic relationships with their bacteria and fungi. Microbial composition and abundance affect bee health through nutrition, immunity, and fitness.
