Abstract—In the present study, presence of endosulfan, imidacloprid, carbendazim, in the soil /vegetables/cereals and water samples was observed in agriculture fields of Uttarakhand. In view of biodegradation of these pesticides, 9 bacterial isolates were recovered from the soil samples of the fields which tolerated endosulfan, imidacloprid, carbendazim from 100 to 200 μg/ml. Three bacterial co...

Habituation of the proboscis extension reflex (PER) in honeybees (Apis mellifera) is age-dependent. Very young bees (< or =7 days old) require significantly less trials to abolish the response to multiple sucrose stimulations than older bees (> or =8 days old). A nicotinic agonist, imidacloprid, modifies this behaviour by increasing the number of trials in < or =7-day-old bees and by decreasing...

Imidacloprid, the most used systemic insecticide, is suspected of having harmful effects on honeybees at nanogram per bee or at microgram per kilogram levels. However, there is a lack of methodology to detect imidacloprid and its metabolites at such low levels. We developed a method for the determination of low amounts of imidacloprid in soils, plants (leaves and flowers), and pollens by using ...

Bumble bees are important pollinators whose populations have declined over recent years, raising widespread concern. One conspicuous threat to bumble bees is their unintended exposure to trace residues of systemic neonicotinoid pesticides, such as imidacloprid, which are ingested when bees forage on the nectar and pollen of treated crops. However, the demographic consequences for bumble bees of...

Imidacloprid is a chloronicotinyl insecticide which interacts with insect nicotinic acetylcholine receptors. Thirty minutes after oral treatment of honeybees with imidacloprid, the olfactory learning performances in a proboscis extension reflex (PER) procedure were impaired. In parallel, an increase of the cytochrome oxidase labelling was found into the calyces of the mushroom bodies. Imidaclop...

The feed costs are the major expenses for farmers and main input that influenced economics of livestock production. physical form diet is one drivers better digestibility improved growth performance farm animals. This study aimed to evaluate effect using two different forms (ground mixtures pelleted mixtures) on fattening lambs. Seventy-two lambs were randomly assigned groups with 36 assess eff...

Periodic sampling of 87 independent monitors, initially active with the Formosan subterranean termite, Coptotermes formosanus Shiraki, was conducted. Monitors, located in eight sectors adjacent to seven buildings, were various distances (1-46 m) from 57 trees treated with 0.1% imidacloprid foam. Termites collected from six of the eight sectors showed latent mortality attributed to imidacloprid ...

A hydrophilic ionic liquid monomer (i.e. 1-(a-methyl acrylate)-3-vinylimidazolium bromide) was immobilized on carboxylated multi-walled carbon nanotubes (MWNTs) by ion exchange, then reversible addition–fragmentation chain transfer precipitation polymerization (RAFTPP) was performed in the presence of a template, imidacloprid. The obtained imidacloprid imprinted material showed a netlike struct...

Western flower thrips (WFT), Frankliniella occidentalis (Pergande), is an important pest of vegetable crops worldwide and has developed resistance to many insecticides. The predatory mites Neoseiulus (=Amblyseius) cucumeris (Oudemans), the entomopathogenic fungus Metarhizium anisopliae (Metsch.), and an insecticide (imidacloprid) were tested for their efficacy to reduce WFT population density a...

Concern is growing over the effects of neonicotinoid pesticides, which can impair honey bee cognition. We provide the first demonstration that sublethal concentrations of imidacloprid can harm honey bee decision-making about danger by significantly increasing the probability of a bee visiting a dangerous food source. Apis cerana is a native bee that is an important pollinator of agricultural cr...
