Risks posed to bees from neonicotinoid seed treatments (clothianidin, thiamethoxam, imidacloprid) led in 2013 the European Union instigating a moratorium for their use on mass-flowering crops, including oilseed rape UK. This restriction did allow continued of these treatments, particular clothianidin, non-flowering crops like winter wheat. To determine impacts moratorium, we assessed concentrat...

Abstract Background In the present study, efficacy of two isolates Beauveria bassiana namely, BKN20 and BKN1/14 was evaluated against tea mosquito bug (TMB), Helopeltis theivora, Waterhouse (Hemiptera: Miridae) damaging harvestable shoots plants in Dooars Darjeeling regions West Bengal, India. Results Laboratory study revealed that, both isolates, more pathogenic than BKN1/14, exhibiting 76% mo...

ABSTRACT: The grapevine phylloxera Daktulosphaira vitifoliae (Fitch, 1856) is the main insect pest of viticulture globally. Infestations can occur in aerial part plant (gallicolae form) and roots (radicicolae form). In this study, effect insecticides on populations suppression gall root forms one vine was evaluated. For gallicolous form, thiamethoxam (Actara 250 WG®, 40g c.p./100L-1), flupyradi...

The psyllid Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is one of the most important pests of citrus worldwide because it efficiently vectors three bacteria in the genus Candidatus Liberibacter that cause the devastating citrus greening disease (huanglongbing). Current management practices for this insect pest rely on multiple sprays of foliar insecticides and one or two applications of so...

BACKGROUND & OBJECTIVES Due to ever growing insecticide resistance in mosquitoes to commonly used insecticides in many parts of the globe, there is always a need for introduction of new insecticides for the control of resistant vector mosquitoes. In this study, larvicidal and adulticidal efficacies of three neonicotinoids (imidacloprid, thiacloprid and thiamethoxam) were tested against resistan...

Neonicotinoid insecticides are nicotinic acetylcholine receptor agonists used worldwide. Their environmental health effects including neurotoxicity are of concern. We previously determined a metabolite of acetamiprid, N-desmethyl-acetamiprid in the urine of a patient, who exhibited some typical symptoms including neurological findings. We sought to investigate the association between urinary N-...

15 There is considerable and ongoing debate as to the harm inflicted on bees by exposure to 16 agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field17 realistic levels of exposure. Here, we quantify concentrations of neonicotinoid insecticides and 18 fungicides in the pollen of oilseed rape, and in pollen of wildflowers growing near arable fields. W...

Management of onion maggot, Delia antiqua (Meigen), in onion requires the use of an insecticide applied at planting. Insecticide resistance and a dearth of available products have stimulated an effort to identify new insecticides for onion maggot control, especially chemistries that can be delivered as seed treatments. Onion seeds film-coated with fipronil, spinosad, clothianidin or thiamethoxa...
