Insecticidal Seed Treatments can Harm Honey Bees [PDF]

open access: yes, 2012
Neonicotinoids are a relatively new class of chemistry to control insects. They are now widely adopted because they are persistent and systemic in plant tissues. Most field crops in Iowa have a neonicotinoid seed treatment.

The amino terminal domain of the human α7 nicotinic acetylcholine receptor subunit leads to the functional expression of human/insect receptors

open access: yesBritish Journal of Pharmacology, EarlyView.
Human α7 receptors have been characterised in terms of pharmacological properties. Insertion of the N‐terminal domain of the human α7 subunit leads to honeybee and cockroach chimeric receptors activated by ACh and inhibited by α‐Bgt. Insertion of the human cys‐loop leads to cockroach chimeric receptors modulated by PNU.

Managing resistance is critical to future use of pyrethroids and neonicotinoids

open access: yesCalifornia Agriculture, 2005
Synthetic pyrethroids and neonicotinoids are the most readily available alternatives to the organophosphate and carbamate insecticides. Pyrethroids have become widely used in California, and problems with insecticide resistance and ...

How dо pesticides get into honey? [PDF]

open access: yes, 2018
Honey is nature’s sweetest gift. But did you know that honey may contain pesticides? Farmers use pesticides to kill pests that harm their crops. But pesticides also hurt honey bees and other beneficial insects.

Edge Effect on the Distribution of the Green Shield Bug Palomena prasina in Hazelnut Orchards, and the Role of Adjacent Habitats in Crop Colonization

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spring–Summer spatial dynamics of Palomena prasina (L.) and potential IPM strategies. ABSTRACT Palomena prasina (L.) (Hemiptera: Pentatomidae), the green shield bug (GSB), is an important hazelnut pest in Southern Europe. Currently, its control focuses on insecticide spraying during the crop season. We hypothesized that, as for other pentatomid species,

Bee worries beyond neonicotinoids [PDF]

open access: yesCurrent Biology, 2018
Summary As the EU ban on the outdoor use of three neonicotinoids is about to come into force, a study shows a new alternative pesticide has similar sublethal but harmful effects. A good solution to the dilemma of distinguishing between useful insects and pests may not exist, but at least the amounts of pesticides released can be reduced.

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

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

open access: yesMedical 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 ...

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

open access: yesMedical 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 ...

Fast neonicotinoid quantification in honey using the one-point internal calibration approach

open access: yesFood Chemistry: X
Neonicotinoids, a highly effective class of insecticides used worldwide, have been identified as a major cause of concern for biodiversity. To assess the ecological and environmental consequences of neonicotinoids' use, reliable analytical methodologies,
