A restatement of recent advances in the natural science evidence base concerning neonicotinoid insecticides and insect pollinators [PDF]

, 2015
A summary is provided of recent advances in the natural science evidence base concerning the effects of neonicotinoid insecticides on insect pollinators in a format (a ‘restatement’) intended to be accessible to informed but not expert policymakers and ...

Neonicotinoids: insecticides acting on insect nicotinic acetylcholine receptors

Trends in Pharmacological Sciences, 2001
Imidacloprid is increasingly used worldwide as an insecticide. It is an agonist at nicotinic acetylcholine receptors (nAChRs) and shows selective toxicity for insects over vertebrates. Recent studies using binding assays, molecular biology and electrophysiology suggest that both alpha- and non-alpha-subunits of nAChRs contribute to interactions of ...

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Looking at Neonicotinoid Insecticides: Environmental Perspective

INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT, 2018
The recent “Global report on Food Crises” published by Food Security Information Network (FSIN, 2017) calls for intervention in methods and technologies to improve the quality and timeliness of food security and tackle the present food crises. India has a huge challenge to feed 1.32 billion and it is a daunting task.

Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations

Pest Management Science, EarlyView.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

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]

, 2019
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

Neonicotinoids thiamethoxam and clothianidin adversely affect the colonisation of invertebrate populations in aquatic microcosms [PDF]

, 2018
Surface waters are sometimes contaminated with neonicotinoids: a widespread, persistent, systemic class of insecticide with leaching potential. Previous ecotoxicological investigations of this chemical class in aquatic ecosystems have largely focused on ...

Neonicotinoids and Optimal Foraging Theory

Environmental Advances, 2022
Determination of how neonicotinoid ingestion affects the foraging behaviour of flower-visiting animals, and using Optimal Foraging Theory to assess the nature and extent of consequent changes to foraging efficiency, provide a novel approach for ...

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Baseline susceptibility and cross-resistance in aphis gossypii glover (Aphididae: Hemiptera) to phorate and sulfoxaflor [PDF]

, 2013
© 2013 State of New South Wales. Susceptible discriminating doses of phorate (0.2 g/L) and sulfoxaflor (0.01 g/L) against cotton aphid Aphis gossypii Glover were determined by laboratory bioassay where aphids were sprayed with insecticide with the aid of
