Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

Entomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Towards the comparative ecotoxicology of bees: the response-response relationship

Julius-Kühn-Archiv, 2012
Background: When an ecological system is exposed to an anthropogenic toxin, each species has an idiosyncratic sensitivity, but it is reasonable to expect some generality in response, especially among related species such as bees.

Comprehensive Survey of Area-Wide Agricultural Pesticide Use in Southern United States Row Crops and Potential Impact on Honey Bee Colonies

Insects, 2019
Honey bees forage across a large area, continually scouting the local landscape for ephemeral food resources. Beekeepers often rely on flowering plants in and around irrigated farmland to maintain their colonies during dry seasons, despite the potential ...

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

Journal of Applied Entomology, EarlyView.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.

Management and drivers of change of pollinating insects and pollination services. National Pollinator Strategy: for bees and other pollinators in England, Evidence statements and Summary of Evidence [PDF]

These Evidence Statements provide up-to-date information on what is known (and not known) about the status, values, drivers of change, and responses to management of UK insect pollinators (as was September 2018). This document has been produced to inform

Pharmacophore of neonicotinoid insecticides

Journal of Pesticide Science, 2008
Our recent study related to neonicotinoid pharmacophore was presented. The first topic described on the QSAR study with 17 variants of 2-nitroiminoimizolidine. The insect neuroblocking potency is proportionally related both to the Mulliken charge on the nitro oxygen atom and log P.

Species composition of blow flies (Diptera: Calliphoridae) colonizing pig carcasses exposed to bifenthrin‐ and clothianidin‐containing products

Medical and Veterinary Entomology, EarlyView.
High clothianidin concentrations prevented colonization, while bifenthrin showed a non‐significant trend of reduced fly abundance, indicating both insecticides may suppress blow fly activity on treated carcasses. Adult emergence rates were unaffected, with no statistically significant differences observed across insecticide treatments, suggesting ...

The impact of weather variability and climate change on pesticide applications in the US - An empirical investigation [PDF]

Weather variability and climate change affect the application of pesticides in agriculture, in turn impacting the environment. Using panel data regression for the US, we find that weather and climate differences significantly influence the application ...

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

Medical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

Physiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...
