In the Sudan, indoor residual spraying (IRS) campaigns currently depend on carbamate insecticide Bendiocarb (2, 2 dimethyl-2H-1,3-benzodioxol-4-yl methyl carbamate; Ficam® 80% WP) at 200 mg/m² against Anopheles arabiensis Patton (Diptera: Culicidae) and other mosquitoes some household pests. Households building materials in targeted villages are mainly constructed by using different local (wood...
Effects of chemical fertilizers (urea, super phosphate and potash) on toxicities of two carbamate insecticides, carbaryl and carbofuran, individually to the N2-fixing cyanobacterium, Cylindrospermum sp. were studied in vitro at partially lethal levels (below highest permissive concentrations) of each insecticide. The average number of vegetative cells between two polar heterocysts was 16.3 in c...
We reported previously that insecticide exposures were widespread among minority women in New York City during pregnancy and that levels of the organophosphate chlorpyrifos in umbilical cord plasma were inversely associated with birth weight and length. Here we expand analyses to include additional insecticides (the organophosphate diazinon and the carbamate propoxur), a larger sample size (n =...
Species Shifts in the Anopheles gambiae Complex: Do LLINs Successfully Control Anopheles arabiensis?
INTRODUCTION High coverage of conventional and long-lasting insecticide treated nets (ITNs and LLINs) in parts of E Africa are associated with reductions in local malaria burdens. Shifts in malaria vector species ratio have coincided with the scale-up suggesting that some species are being controlled by ITNs/LLINs better than others. METHODS Between 2005-2006 six experimental hut trials of IT...
Vinyl carbamate was much more active (10 to 50 times) than ethyl carbamate for the initiation of skin tumors and for the induction of lung adenomas in mice. Vinyl carbamate was also mutagenic to Salmonella typhimurium TA 1535 and TA 100 in the presence of reduced nicotinamide adenine dinucleotide phosphate-fortified rat or mouse liver mitochondrial supernatant fractions. This mutagenic activity...
Abstract Regioselective tritylation and carbonate aminolysis were employed in this work to synthesize cellulose 2,3- bis (3,5-dimethylphenyl carbamate)-6-( α -phenylethyl carbamate)-type chiral selectors. We evaluated optimized the critical aspects of regioselective detritylation at C6 glucopyranose units polysaccharide backbone. The advantage using II comparison I for was analyzed time determi...
Aldicarb, 2-methyl-2-(methylthio)propionaldehyde-O-methylcarbamoyloxime, is an oxime carbamate insecticide manufactured by the Union Carbide Corporation and sold under the trade name Temik. It is a soil-applied systemic pesticide used against certain insects, mites, and nematodes, and is applied below the soil surface for absorption by plant roots. It is generally applied to the soil in the for...
