Although neonicotinoids are targeted at insects, their predominant use as a seed dressing and their long persistence in soils mean that non-target soil organisms such as earthworms are likely to be chronically exposed to them. Chronic exposure may pose risks that are not evaluated in most toxicity tests. We experimentally tested the effect of field-realistic concentrations of a commonly used ne...

Neonicotinoid insecticides have come under scrutiny for their potential unintended effects on non-target organisms, particularly pollinators in agro-ecosystems. As part of a larger study of neonicotinoid residues associated with maize (corn) production, 76 water samples within or around the perimeter of 18 commercial maize fields and neighbouring apiaries were collected in 5 maize-producing cou...

The ubiquitous use of agrochemicals is one driver for the ongoing loss insect biomass and diversity. Data show that field-realistic concentrations neonicotinoid insecticides can negatively affect both population density fitness solitary bees. However, underlying mechanisms these effects remain poorly understood. Here, using an established semi-field experimental set-up Osmia cornuta as a bee mo...

Increased use of neonicotinoid-coated crop seeds introduces greater amounts insecticides into the environment, where they are vulnerable to transport. To understand transport neonicotinoids from agricultural fields, we planted maize (Zea mays L.) coated with thiamethoxam in lysimeter plots central Pennsylvania. Over next year, sampled water generated by rainfall and snowmelt analyzed these samp...

Abstract The objective of this work was to evaluate the effect industrial treatment with insecticides on physiological quality corn (Zea mays) seeds during storage at different temperatures. Seeds BM 950 PRO3 and 709 PRO2 hybrids were subjected based chlorantraniliprole, cyantraniliprole, clothianidin, as well a control, stored temperatures (10, 20, 30°C) for 0, 90, 180, 270, 360 days, in 4x3x5...

The use of insecticides, especially neonicotinoids (NEOCs), poses a significant threat to honey bees, thus prompting the EU ban all outdoor uses clothianidin, imidacloprid, and thiamethoxam. However, due persistence NEOCs, as well fact that certain NEOCs are in some areas world, exposure them is still an on-going issue. In present study, we used laboratory acute toxicity test examine effects su...

The toxicities of established and new members of the neonicotinoid insecticide class were assessed against the glassy-winged sharpshooter in topical application bioassays. All compounds were highly toxic to the insect. Clothianidin elicited its toxic response more rapidly than thiamethoxam and was 3-fold more toxic overall at the LD50 level. Clothianidin has been proposed as an active derivativ...

Extensive and misuse of pesticides can cause to toxicity humans pollution in the environment. The primary objective this study was determine insecticide load agricultural soils Troia, located Troia National Park Çanakkale Province (Türkiye) by QuEChERS method. For method verification, blank soil samples were spiked at two levels pesticides. overall recovery 84.8% with a relative standard deviat...
