Peer review of the pesticide risk assessment for bees for the active substance clothianidin considering the uses as seed treatments and granules

EFSA Journal, 2018
EFSA was asked by the European Commission to perform an updated risk assessment of neonicotinoids, including clothianidin, as regards the risk to bees, as a follow up of previous mandates received from the European Commission on neonicotinoids.

RNAi‐based functional genomics tools for the beet leafhopper using microinjection and nanoparticle‐based topical spray

Insect Science, EarlyView.
• First demonstration of functional RNAi in the beet leafhopper, Neoaliturus tenellus, using both dsRNA microinjection and star polycation nanoparticle‐mediated topical spray delivery.•Microinjection achieved over 90% knockdown of Gus and Pum3, revealing gene‐specific fitness effects on survival and fecundity in beet leafhopper.•Nanoparticle‐mediated ...

Matrix-Induced Sugaring-Out: A Simple and Rapid Sample Preparation Method for the Determination of Neonicotinoid Pesticides in Honey

Molecules, 2019
In the present work, we developed a simple and rapid sample preparation method for the determination of neonicotinoid pesticides in honey based on the matrix-induced sugaring-out.

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

Agricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

Agricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

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%.

Short- and long-term effects of neonicotinoid application in rice fields, on the mortality and colony collapse of honeybees (Apis mellifera)

Journal of Apicultural Science, 2013
Declines in honeybee (Apis mellifera ) colonies have elicited great concern worldwide. Recently, many Japanese beekeepers have implied that midsummer use of a new insecticide, neonicotinoid, in rice fields, is causing widespread mortality of neighboring ...

Asymmetric Regulatory Embeddedness and Post‐Brexit Governance: Explaining Adaptive Convergence in the United Kingdom

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Why has the United Kingdom repeatedly restored substantive compatibility with European Union (EU) regulatory norms despite formal withdrawal? This article introduces the concept of asymmetric regulatory embeddedness (ARE) to explain post‐membership governance in highly integrated sectors. ARE captures the structural condition in which a former

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.
