background: carbaryl is a carbamate insecticide widely used to control pests in agriculture and farm. carbaryl adversely affect the reproductive endocrine systems in animals. objective: the aim of this study was to evaluate carbaryl effects on the pituitary-gonad axis in rats. materials and methods: in this experimental - analytical study, 60 adult male rats were divided into four equal groups:...

Aquatic risk assessment can be improved if we are able to quantitatively predict the effects resulting from sequential pulsed exposure to multiple compounds. We evaluate two modeling approaches, both extended to suit multiple compounds, the semi-mechanistic threshold damage model (TDM), and a model based on time-weighted averages (TWA). The TDM predicts that recovery of damage to Gammarus pulex...

Solanum melongena Linn. (brinjal) is the most common, popular and principal vegetable crop grown in many geographical parts in India. This staple vegetable crop is extensively damaged by the insects and farmers use large quantities of chemical insecticides, Carbaryl being one of them. The present study was undertaken to evaluate the persistence of Carbaryl on brinjal (fruit) and soil in an agri...

Four acaricides (amitraz, cyfluthrin, permethrin, and pyrethrins) were studied for their efficacy in the rapid killing of Amblyomma americanum, A. cajennense, and A. maculatum (Acari: Ixodidae) and eight acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, permethrin, pyrethrins, and selamectin) for their efficacy in the rapid killing of Rhipicephalus sanguineus (Acari: Ixodidae)....

The document reviews the environmental fate and environmental effect of carbaryl (1-naphthyl-N-methyl carbamate). Carbaryl is one of the most frequently used carbamate insecticides and widely used for the control of a variety of pests on fruit, vegetables, forage, cotton and many other crops, as well as on poultry, livestock and pets (Mathew et al., 1995). It is available as wettable powders, p...

A new and simple approach for carbaryl determination in natural sample was proposed using Low Silica X (LSX) zeolite modified carbon paste electrode. LSX zeolite with a porous structure was incorporated into carbon paste electrode in the appropriate portion. The prepared electrode was then characterized using scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectro...

A portable flow analysis instrument is described for in situ photometric measurements. This system is based on light-emitting diodes (LEDs) and a photodiode detector, coupled to a multipumping flow system. The whole equipment presents dimensions of 25 cm x 22 cm x 10 cm, weighs circa 3 kg, and costs 650 euro. System performance was evaluated for different chemistries without changing hardware c...

It is known that the enzyme activities of non-target organisms are influenced in vivo or vitro by pesticides play a major role to obtain higher yields field agriculture. foreseen used for various purposes may negatively affect lipase, an digestive system, non target organisms. Therefore, this study, effect diazinon (organophosphate class) and carbaryl (carbamate pesticides, which be widely agri...

Environmental contaminants and disease may synergistically contribute to amphibian population declines. Sub-lethal levels of contaminants can suppress amphibian immune defenses and, thereby, may facilitate disease outbreaks. We conducted laboratory experiments on newly metamorphosed foothill yellow-legged frogs (Rana boylii) to determine whether sublethal exposure to the pesticide carbaryl woul...
