Fungicide Non‐Target Effects Cause Reduced Sawfly Herbivory in Treated and Neighbouring Strawberry Plants

Entomologia Experimentalis et Applicata, EarlyView.
Application of the fungicide Switch 62.5 WG in garden strawberry (Fragaria × ananassa), targeting Botrytis cinerea, reduced sawfly (Cladius spp.) herbivory by up to 94% and improved fruit quality. This non‐target effect also spilled over to neighbouring untreated plants, lowering damage by 46%.

Field-level clothianidin exposure affects bumblebees but generally not their pathogens

Nature Communications, 2018
The potential impact of neonicotinoid field exposure on bumblebee microbiota remains unclear. In a landscape—scale study, Wintermantel et al. show that whilst exposure to clothianidin impacts Bombus terrestris performance, it does not affect levels of ...

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

Ecological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

Ecological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Sweet connections: the role of honeydew in supporting wild Bombus terrestris populations (Hymenoptera, Apidae) – a case study from Türkiye [PDF]

Journal of Hymenoptera Research
Honeydew is a sugary excretion produced by sap-feeding hemipterans, such as scale insects and aphids. It has been regarded predominantly as a food resource for predators and omnivores insects.

Floral richness drives flower–insect networks in city gardens and allotments

Ecological Entomology, EarlyView.
Floral richness was the main driver of flower visits within green spaces whilst green space in the surrounding landscape influenced flower visits by amplifying the effects of floral richness. Native plants received more visits than non‐native plants, although flower visitor richness to non‐native plants increased later in the season as non‐native plant

Photoreceptor spectral sensitivity in the bumblebee, Bombus impatiens (Hymenoptera: Apidae).

PLoS ONE, 2010
The bumblebee Bombus impatiens is increasingly used as a model in comparative studies of colour vision, or in behavioural studies relying on perceptual discrimination of colour.

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...
