Pest Management Science, EarlyView.SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Pest Management Science, EarlyView.Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

The Neurophysiological Bases of the Impact of Neonicotinoid Pesticides on the Behaviour of Honeybees
Insects, 2019 Acetylcholine is the main excitatory neurotransmitter in the honeybee brain and controls a wide range of behaviours that ensure the survival of the individuals and of the entire colony.

A beekeeper's perspective on the neonicotinoid ban [PDF]
Pest Management Science, 2017 Abstract Bees and agrochemicals have a long history. For example, the first volume of IBRA 's journal Bee World in 1919 contains mention of poisoning of bees by spraying an orchard with lead arsenate.

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 ...

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.

Evaluation of the FERA study on bumble bees and consideration of its potential impact on the EFSA conclusions on neonicotinoids [PDF]
EFSA Journal, 2013 The European Food Safety Authority was requested to clarify whether the new publication on the effects of neonicotinoid seed treatments on bumble bee colonies under field conditions (March, 2013; Thompson et al.) has an impact on the EFSA Conclusions on ...

Pest Management Science, EarlyView.Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Neonicotinoids interfere with specific components of navigation in honeybees. [PDF]
PLoS ONE, 2014 Three neonicotinoids, imidacloprid, clothianidin and thiacloprid, agonists of the nicotinic acetylcholine receptor in the central brain of insects, were applied at non-lethal doses in order to test their effects on honeybee navigation.

Pest Management Science, EarlyView.Phenotypic and transcriptional responses to imidacloprid and isocycloseram were examined across U.S. populations of the Colorado potato beetle, showing evidence of phenotypic cross‐resistance alongside population‐level variation in detoxification gene expression.
