Comparison of Pesticide Exposure in Honey Bees (Hymenoptera: Apidae) and Bumble Bees (Hymenoptera: Apidae): Implications for Risk Assessments

open access: yesEnvironmental Entomology, 2018
To date, regulatory pesticide risk assessments have relied on the honey bee (Apis mellifera L.) (Hymenoptera: Apidae) as a surrogate test species for estimating the risk of pesticide exposure to all bee species. However, honey bees and non-Apis bees may differ in their susceptibility and exposure to pesticides.

Chemotaxonomical characterisation of males of Bombus lucorum (Hymenoptera: Apidae) collected in the Czech Republic

open access: yesEuropean Journal of Entomology, 2001
Labial gland secretions of 26 males of the bumblebee Bombus lucorum (L.), collected in the Czech Republic, were analysed. The secretions consisted of 60 compounds; ethyl (Z)-9-tetradecenoate was the main component (average 53%). Although the males varied

Does behaviour matter? The role and feasibility of research into arthropod behavioural syndromes to inform invertebrate translocation efforts

open access: yesInsect Conservation and Diversity, EarlyView.
Animal personality plays a key role in translocation success in both wild‐to‐wild and captive‐to‐wild translocations, with important implications for the success of conservation projects. However, the majority of studies so far have explored the link between personality and translocation success in vertebrate translocations, and there has been less ...

A gynandromorph of Xylocopa nigrocincta Smith (Hymenoptera: Apidae) [PDF]

open access: yesNeotropical Entomology, 2009
We describe a mixed gynandromorph of Xylocopa (Neoxylocopa) nigrocincta from a single specimen from Argentina. The specimen presents bilateral asymmetry, with the right half of its head displaying male characters and the left half displaying female characters; the mesosoma presents male characters mostly in the right half of the prothorax, pronotal ...

Genome-wide discovery and characterization of microsatellite markers from Melipona fasciculata (Hymenoptera: Apidae), cross-amplification and a snapshot assessment of the genetic diversity in two stingless bee populations

open access: yesEuropean Journal of Entomology, 2018
Brazilian native meliponines are currently threatened by increased human impacts. The assessment of their genetic variation by microsatellite DNA markers can assist in the conservation of populations and help in the planning and establishment of ...

Observations on Colony Size in Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

open access: yes, 2017
(excerpt) One factor to consider when attempting to rear bumblebees (Bombus spp.) for pollination of crops is potential colony size. Species which emerge from hibernation early and continue to produce workers late in the summer or early fall are likely ...

Impact of Mulches on Floral Visitors in Day‐Neutral Strawberries and Contribution of Syrphid Flies to Strawberry Pollination

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Animal‐mediated pollination is essential for the production of many specialty crops, with insects, primarily bees, serving as the predominant pollinators in many agroecosystems. However, increasing management problems with honey bees and declines in native bee populations due to various environmental stressors have highlighted the importance ...

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]

open access: yes, 2015
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Ensuring Pollinator Presence in Expanding Oil Crops: The Case of Mystrops debilis (Nitidulidae) and the Macauba Palm (Acrocomia aculeata, Arecaceae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The macauba palm (Acrocomia aculeata, Arecaceae) is a Neotropical native oil palm, increasingly important in Central and South America due to rising demand for raw materials and its potential for bioenergy. Understanding its pollinator ecology is crucial to identify new areas for cultivation. This study examines the structure of floral visitor
