A GABA Receptor Modulator and Semiochemical Compounds Evidenced Using Volatolomics as Candidate Markers of Chronic Exposure to Fipronil in Apis mellifera

open access: yesMetabolites, 2023
Among the various “omics” approaches that can be used in toxicology, volatolomics is in full development. A volatolomic study was carried out on soil bacteria to validate the proof of concept, and this approach was implemented in a new model organism ...

The role of UV in crab spider signals: effects on perception by prey and predators [PDF]

open access: yes, 2005
Australian crab spiders Thomisus spectabilis sit on the petals of flowers and ambush prey such as honeybees. White-coloured T. spectabilis reflect in the UV (UV+ spiders) and previous research has shown that their presence, curiously, attracts honeybees ...

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]

open access: yes, 2018
Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

Economics of alternative insecticide treatments and pollinators in Winter canola

open access: yesCogent Food & Agriculture, 2023
In the US central and southern Great Plains, canola (Brassica napus) is a winter annual crop. It is pollinated by insects, particularly native bees and introduced honeybees (Apis mellifera Linnaeus, 1758). Canola is beset by many insect pests.

Pollination services in the UK: how important are honeybees? [PDF]

open access: yes, 2011
Pollination services are known to provide substantial benefits to human populations and agriculture in particular. Although many species are known to provide pollination services, honeybees (Apis mellifera) are often assumed to provide the majority of ...

Combined Effects of Pesticides and Electromagnetic-Fields on Honeybees: Multi-Stress Exposure

open access: yesInsects, 2021
Honeybee and general pollinator decline is extensively reported in many countries, adding new concern to the general biodiversity loss. Many studies were addressed to assess the causes of pollinator decline, concluding that in most cases multi-stress ...
