Larvicidal activity of some Salvia L. (Labiatae) plant extractsagainst the mosquito Culex pipiens L. (Diptera: Culicidae) [Bazi{dotless} Salvia L. (Labiatae) bitki ekstraktlari{dotless}ni{dotless}n,sivrisinek Culex pipiens L. (Diptera: Culicidae)'e karşi{dotless} larva öldürücü aktivitesi]

In this research,the hexane extracts of the aerial parts of four salvia l. (labiatae) species,collected from antalya,turkey,were tested for larvicidal activity against the mosquito culex pipiens l. (diptera: culicidae) under laboratory conditions. third and fourth instar mortality from six diff erent concentrations (10,25,50,100,150 and 200 ppm) of each plant extract were examined. when the results were examined,extract of salvia tomentosa mill. was the most toxic,followed by those of s. sclarea l.,s. argentea l. and s. syriaca l. with lc50 values 60.61,62.05,107.40 and >200 ppm,respectively. the results indicated that the hexanic extracts of different salvia species may show the high larvicidal activities.
