The aims of this work were to monitor the dissipation dynamics organophosphate insecticides applied corn grains stored in supervised experiments, establish and determine minimum period post application necessary comply with established commercial standards. dichlorvos (DDVP), hlorpyrifosmethyl+deltamethrin (CPM) pirimiphos-methyl (PMM) maize grains, which then for 120 days. samples processed ex...
Introduction: Chlorpyrifos (CPF), an organophosphate insecticide, was evaluated for potential teratogenic effects in mice. A single oral dose of insecticide (i.e. 72, 36 18 or 9 mg/kg) was given to the pregnant females on gestation day6 (GD6). These doses correspond 50, 25, 12.5 and 6.25% to the calculated LD50 value (144 mg/kg) for the pregnant mice. No signs of overt toxicity were observed at...
Background: Environmental pollutants including organophosphate insecticides impair glucose metabolism by altering hepatic oxidation and play an important role in the development of diabetes and its complications. The aim of this study was to assess the impacts of repeated oral doses of Diazinon, an organophosphate insecticide, which is known to impair the glucose metabolism and its tolerance th...
background: diazinon is a widely used organophosphate insecticide which is applied against plant pests. this compound has various side effects because it acts as an acetyl cholinesterase enzyme inhibitor. objective: the aim of present study was to investigate the effects of diazinon on pituitary–gonad axis and ovarian histological changes in rats. materials and methods: in total 50 female wista...
The impact of commonly used organophosphate (chlorpyrifos, methamidophos), carbamate (carbaryl), and pyrethroid (cypermethrin) insecticides on insect natural enemies was compared with that of a nucleopolyhedrovirus (Baculoviridae) of Spodoptera frugiperda (J. E. Smith) (Lepidoptera Noctuidae) in maize grown in southern Mexico. Analyses of the SELECTV and Koppert Side Effects (IOBC) databases on...
Neurotoxic pesticides are known to contaminate surface waters that provide habitat for salmonids, including some listed for protection under the U.S. Endangered Species Act. Despite their widespread use, the impacts of these pesticides on the neurological health of wild salmon are not well understood. Of particular concern are the organophosphate and carbamate insecticides that block synaptic t...
