We examined the effects of a commonly used AChE-inhibiting pesticide on terrestrial and arboreal sprint performance, important traits for predator avoidance and prey capture, in the western fence lizard (Sceloporus occidentalis). Lizards were exposed to carbaryl (2.5, 25, and 250 microg/g) and were raced before and 4, 24, and 96 h after dosing. In the terrestrial setting, exposure to low concen...

Pesticides and heavy metals are common environmental contaminants that can cause neurotoxicity to aquatic organisms, impairing reproduction and survival. Neurotoxic effects of cadmium and carbaryl exposures were estimated in larval rainbow trout (RBT; Oncorhynchus mykiss) using changes in physiological endpoints and correlations with behavioral responses. Following exposures, RBT were videotape...

Maintenance, expressed as change in daily body mass, and survival rates of Mastomys natalensis (sensu lato) were recorded from May to September 1994 in laboratory feeding trials, to investigate the short-term effects of a carbaryl insecticide on these variables. Individuals were subjected to seeds treated with carbaryl insecticide in three different treatments (5, 10, and 20 g of carbaryl/kg of...

The objective of this research was to examine the efficiency of carbaryl under laboratory conditions, based on field populations of poultry red mites from throughout the Republic of Serbia and Montenegro over a period of 6 years (2001-2006). In 2001 samples, an excellent efficiency level of 95.7% at 0.1% carbaryl concentration after 30-minute exposure was found. The total pharmacological profil...

Exposure of nontarget populations to agricultural chemicals is an important aspect of global change. We quantified the capacity of natural Daphnia magna populations to locally adapt to insecticide exposure through a selection experiment involving carbaryl exposure and a control. Carbaryl tolerance after selection under carbaryl exposure did not increase significantly compared to the tolerance o...

Lodgepole and ponderosa pine trees were treated with a 2% carbaryl solution at recreational areas near Fort Collins, CO, in June 2010 as a prophylactic bole spray against the mountain pine beetle. Bark samples from treated and untreated trees were collected one day following application and at 4-month intervals for one year. The residual amount of carbaryl was determined, and bark samples were ...

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...
