In studies designed to determine the factors responsible for control of herpesvirus replicaton in an infected cell, we examined the interaction of varicella-zoster (VZ) virus-infected human embryonic lung cells with the pesticide carbaryl. The replication of the cell-associated VZ virus was enhanced 2- to 13-fold as compared to control cultures in Sevin 4 Oil-treated cultures and in cultures tr...

Carbaryl (200 mg/kg or #00 mg/kg, p.o.) significantly elevated serotonin (5-HT) (57-109%) and 5-hydroxyindoleacetic acid (5-HIAA) (60-7g%) levels at t.0 h in the hypothalamic region of adult male rat brain. Further, administration of carbaryl (200 mg/kg, p.o.) for different time intervals (0.5 h, 1.0 h, and 2.0 h) revealed that both 5-HT and 5-HIAA levels elevated maximally at 0.5 h in hypothal...

Goldfish virus-2 replication was enhanced in vitro by pretreatment of CAR cells with subcytotoxic concentrations of carbaryl and toxaphene. This phenomenon was time and temperature dependent. Shortening of pretreatment with carbaryl eliminated enhancement, which was observed for toxaphene only with substantially increased concentrations. Decreasing the temperature of pretreatment (4 degrees C) ...

Carbaryl (1-naphthyl N-methylcarbamate) is a most widely used carbamate pesticide in the agriculture field. Soil isolate, Pseudomonas sp. strain C5pp mineralizes carbaryl via 1-naphthol, salicylate and gentisate, however the genetic organization and evolutionary events of acquisition and assembly of pathway have not yet been studied. The draft genome analysis of strain C5pp reveals that the car...

The majority of studies on pesticide impacts have evaluated the effects of single exposures. However, multiple exposures to a pesticide may be more prevalent. The objective of our study was to determine how multiple exposures versus single exposure at different times during development affected survival to metamorphosis, tadpole survival, tadpole mass, and tadpole developmental stage of green f...

background: carbaryl (1-naphthyl-n-methyl carbamate) is a chemical in the carbamate family used chiefly as an insecticide. it is a cholinesterase inhibitor and is toxic to humans and classified as a likely human carcinogen. in the present study, the degradation of the carbaryl pesticide was investigated in the laboratory synthetic samples of tap water, in the effect of sonolysis and photolysis ...

Surface water sampling in 2007-2010 measured the occurrence of carbamates and metalaxyl during base flow conditions and wet weather events in southern Ontario surface waters. Carbaryl, metalaxyl and pirimicarb were the most frequently detected compounds. In 2008 these three compounds were detected in over 50 % of the samples. Overall mean concentrations of carbaryl and metalaxyl over the course...

background : insecticide resistance is one of the serious problems for german cockroach control program. this study was conducted to determine the bendiocarb and carbaryl resistance mechanisms in german cockroaches using the piperonyl butoxide (pbo). methods : bioassay tests were conducted with 4 to 6 different concentrations of both insecticides with four replicates of 10 susceptible strain co...
