| field evaluation of a lethal ovitrap against dengue vectors in brazil. | field evaluation of a "lethal ovitrap" (lo) to control dengue vector aedes mosquitoes (diptera: culicidae), was undertaken in two brazilian municipalities, areia branca and nilopolis, in the state of rio de janeiro. the lo is designed to kill aedes via an insecticide-treated ovistrip (impregnated with deltamethrin). in each municipality, the intervention was applied to a group of 30 houses (10 los/house) and compared to 30 houses without los in the same neighbourhood. five los were put outside a ... | 2003 | 12823838 |
| [biology and thermal exigency of aedes aegypti (l.) (diptera: culicidae) from four bioclimatic localities of paraíba]. | the present work aimed at estimating the thermal requirements for the development and the number of generations per year of aedes aegypti (l.) under natural conditions. the life cycle of a. aegypti populations was studied at constant temperatures of 18, 22, 26, 30 and 34 degrees c, and 12 h photophase. the development period, egg viability and larval and pupal survival were evaluated daily as well as adult longevity and fecundity. the low threshold temperature of development (tb) and the thermal ... | 2006 | 17273720 |
| [resistance of aedes aegypti (l.) (diptera: culicidae) populations to organophosphates temephos in the paraíba state, brazil]. | rumors of aedes aegypti (l.) resistance to temephos in diferent brazilian states justified this research, whose objective was to verify and characterize the resistance to temephos in a. aegypti populations from paraíba state. the temephos resistance was evaluated and characterized through a diagnostic dose of 0.012 mg/l and concentration-mortality curves. the mortality data of multiple concentrations were submitted to probit analysis, and the resistance ratios (rr) were figured out from the cl50 ... | 2007 | 17607466 |
