Larvicidal activity of extracts from Quercus lusitania var. infectoria galls (Oliv.).
نویسندگان
چکیده
The present study indicates the efficacy of extracts and fractions of Quercus lusitania var. infectoria galls (Oliv.) as larvicidal agents and their possible use in biological control of Culex pipiens, the urban nuisance mosquito. Extracts and fractions were tested against second and fourth instar larvae. The LC(50) values of gallotannins were 335 and 373 ppm, respectively for the 2nd and 4th instar period. The most interesting value of LC(50) (24 h) is obtained with the fraction F(2) (60 ppm).
