This study investigated the effects of diazinon, an organic phosphoric insecticide, on some developmental features of Drosophila melanogaster. The aim was to determine if any developmental inhibition occurs when diazinon is applied and if so, to determine which developmental stages are affected. Therefore, diazinon was applied to Drosophila melanogaster eggs, larvae, and adults, and its effects...

Harold M. Monteclaro, Kazuhiko Anraku, Seiichi Uno, Jiro Koyama, Tatsuro Matsuoka, and Hong-Young Yan (2011) Sensitivity of crayfish Procambarus clarkii antennules to hydrodynamic stimuli is reduced during diazinon exposure. Zoological Studies 50(2): 145-154. In this study, the susceptibility of crustacean antennular mechanosensitivity to a pesticide was examined. We investigated the sensitivit...

Formulation components of organophosphate insecticidal preparations might affect their toxic action in animals. The objective of this study was to examine and compare the acute toxicity and cholinesterase inhibition in seven to 14-day-old chicks dosed orally with dichlorvos and diazinon in standard veterinary and agricultural formulations. The acute (24 h) oral median lethal doses (LD50) of the...

Diazinon [O,O-diethyl O-2-isopropyl-6-methyl(pyrimidine-4-yl) phosphorothioate] and imidacloprid [1-(1-[6-chloro-3-pyridinyl]methyl)-N-nitro-2-imidazolidinimine] are applied to lawns for insect control simultaneously with nitrogenous fertilizers such as urea, but their potential effect on urease activity and nitrogen availability in turfgrass management has not been evaluated. Urease activity i...

OBJECTIVE Diazinon causes oxidative stress and dysfunction of the liver. This study was undertaken to evaluate the effects of the hydroalcoholic extract of Terminalia chebula, on some biochemical and histopathological parameters of liver tissue in diazinon-administered rats. MATERIALS AND METHODS Wistar rats were orally administered with 25 mg/kg body weight diazinon. Vehicle (distilled water...

considering that the involvement of oxidative stress has been implicated in the toxicity of organophosphate insecticides, the objective of the present study was to investigate antioxidants and oxidative stress markers in the liver and kidney of wistar rats treated with chronic doses of diazinon. in addition, the effect of tert-butylhydroquinone (tbhq), a food-additive antioxidant, on attenuatio...

BACKGROUND The fibroblast growth factor (FGF) superfamily of neurotrophic factors plays critical roles in neural cell development, brain assembly, and recovery from neuronal injury. OBJECTIVES We administered two organophosphate pesticides, chlorpyrifos and diazinon, to neonatal rats on postnatal days 1-4, using doses below the threshold for systemic toxicity or growth impairment, and spannin...

In intensively cultivated areas, agriculture is a significant source of pesticides associated with storm runoff. When these pollutants enter aquatic receiving waters, they have potential to damage nearby aquatic ecosystems. Constructed wetlands are a best management practice (BMP) designed to help alleviate this potential problem. A constructed wetland system (180×30 m) comprised of a sediment ...

This project was primarily funded by a contract with the Department of Pesticide Regulation (DPR) of the California Environmental Protection Agency. The contract was supported by an allotment dedicated to the pesticide monitoring priorities of the California Regional Water Quality Control Boards. The statements and conclusions in this report are those of the contractor and not necessarily those...

Background/Aim. Organophosphate pesticides (OPs) are used extensively worldwide in agriculture and forestry, their application represents a major health problem for humans animals. The aim of this study was to investigate the possibility adaptation an organism pro-longed administration low dose diazinon. Methods. conducted on total 60 male Wistar rats. first 30 rats were divided into four equal...
