The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is one of the most important pests of citrus (Citrus spp.) because of its status as a vector of Candidatus Liberibacter asiaticus (Las), the bacterium associated with citrus greening disease. The use of insecticides for vector control is the primary method of managing the spread of this pathogen. Imidacloprid is an inse...

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...

In order to develop an indirect competitive enzyme-linked immunosorbent assay (ELISA) for the insecticide imidacloprid, the anti-imidacloprid polyclonal antibody was produced and the affinity of three different coating antigens with the polyclonal antibody was compared. The antigenic determinant in antigen aiming at the polyclonal antibody was raised and analyzed. The standard curve for imidacl...

Boric acid, imidacloprid, and thiamethoxam in sucrose aqueous baits had different delayed toxicities to worker Argentine ants, Linepithema humile (Mayr). The concentrations required to produce an LT50 (time required to produce 50% mortality) within 1-4 d were 3.63-0.55% boric acid, 9.2 x 10(-3) to 7.1 x 10(-4)% imidacloprid, and 3 x 10(-4) to 2 x 10(-5)% thiamethoxam. The three toxicants were n...

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...

Field-based studies and laboratory bioassays were conducted with apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, Rhgoletis mendax Curran, flies to investigate the performance and duration of activity of insecticide-treated biodegradable and wooden spheres for control of Rhagoletis species. Four neonicotinoid insecticide treatments including imidacloprid, thiamethoxam, and thio...

ELISA techniques were used to detect imidacloprid in guttation fluid of young cantaloupe plants in Arizona. Imidacloprid was detected at up to 4.1 microg/ml (ppm) in a coincidental guttation collection 3 d after a top label rate soil application and at 37 microg/ml one d after a separate top label rate soil application study. These imidacloprid titers exceed reported median oral toxicities for ...

The dramatic loss of honey bees is a major concern worldwide. Previous studies have indicated that neonicotinoid insecticides cause behavioural abnormalities and have proven that exposure to sublethal doses of imidacloprid during the larval stage decreases the olfactory learning ability of adults. The present study shows the effect of sublethal doses of imidacloprid on the neural development of...

Boric acid, imidacloprid, and thiamethoxam in sucrose aqueous baits had different delayed toxicities toworker Argentine ants,Linepithema humile (Mayr). The concentrations required toproduce anLT50 (time required toproduce 50%mortality)within 1Ð4dwere 3.63Ð0.55%boric acid, 9.2 10 3 to 7.1 10 % imidacloprid, and 3 10 4 to 2 10 % thiamethoxam. The three toxicants were not repellent. Other laborato...

BACKGROUND Imidacloprid has been commonly used as a pesticide for crop protection and acts as nicotinic acetylcholine receptor agonists. Little information about the relationship between imidacloprid and allergy is available. OBJECTIVE This study aims to examine the effects of imidacoprid on IgE-mediated mast cell activation. METHODS The rat basophilic leukemia cell line RBL-2H3 (RBL-2H3 ce...
