Effectiveness of interval photography cameras for a survey of pollinator communities: Comparison with direct observation

Applications in Plant Sciences, EarlyView.
Abstract Premise Pollinator communities have been surveyed through direct observation, which is labor intensive and difficult for monitoring nocturnal pollinators. Interval photography surveys are increasingly used, although the resulting data from pollinator community surveys have rarely been validated. Methods We surveyed a pollinator community using

Evidence of forage distance limitations for small bees (Hymenoptera: Apidae)

European Journal of Entomology, 2015
The distribution of ground-nesting bees was investigated using transects of water traps in a mosaic of nesting and forage habitats at Shotover Hill in Oxfordshire, UK. The site includes a large area of ground-nesting bee activity and is adjoined on three

Susceptibility to cyflumetofen in populations of the citrus leprosis mite, Brevipalpus yothersi, from Brazilian citrus orchards

Pest Management Science, EarlyView.
Brevipalpus yothersi, the vector of citrus leprosis virus, showed high susceptibility to cyflumetofen. Its low resistance suggests it is effective, but should be rotated with other acaricides with different modes‐of‐action for sustainable management.

Sperm viability in the male accessory testes and female spermathecae of the bumblebee Bombus terrestris (Hymenoptera: Apidae)

European Journal of Entomology, 2008
In many species sperm competition selects for large ejaculates while females eliminate or disable a high percentage of the spermatozoa in their storage organs in order to control paternity.

The Economics of Honey Bee (Hymenoptera: Apidae) Management and Overwintering Strategies for Colonies Used to Pollinate Almonds

Journal of Economic Entomology, 2019
Commercial honey bee (Apis mellifera L.) colonies significantly contribute to agricultural productivity through crop pollination. Almond production requires the most colonies because there are more than a million acres of orchards that require cross ...

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Bumblebee (Hymenoptera: Apidae) sample storage for a posteriori molecular studies: Interactions between sample storage and DNA-extraction techniques

European Journal of Entomology, 2013
A global decline in pollinator abundance and diversity has demanded increased research attention to the ecology and genetics of bumblebees. However, as progressively more restrictions are placed on sampling for insects, researchers are increasingly ...

Pollenkitt is associated with the collectability of Malvoideae pollen for corbiculate bees

Journal of Pollination Ecology, 2023
Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble bees and honey bees from exploiting pollen resources.

Assessment of Pollen Diversity Available to Honey Bees (Hymenoptera: Apidae) in Major Cropping Systems During Pollination in the Western United States

Journal of Economic Entomology, 2019
Global western honey bee, Apis mellifera (L.) (Hymenoptera: Apidae), colony declines pose a significant threat to food production worldwide. Poor nutrition resulting from habitat loss, extensive monocultures, and agricultural intensification is among the

Mixed plant and arthropod biodiversity responses to solar park establishment on former agricultural lands

Journal of Applied Ecology, EarlyView.
Our results suggest that while biodiversity can increase in solar parks post‐conversion compared to previous land use, not all taxonomic groups benefit from the land use change. Potential benefits for certain groups (particularly for butterflies and soil‐emergent arthropods) are likely lost due to disturbance during land conversion and solar panel ...
