Abstract

The baseline susceptibility studies were carried out in the laboratory maintained strains of Anopheles Stephensi, Liston one of the important malaria vectors in the Indian subcontinent. Altogether 30 strains were subjected by taking late 3rd instar larvae for two synthetic pyrethroids i.e. alphamethrin and bifenthrin and a botanical insecticide, neem by applying standard larval test procedure of World Health Organization. The data clearly showed that the lowest LC50 value of 0.000056 mg/l was observed in Shimoga (SMG) strain whereas the highest LC50 value of 0.024 mg/l was recorded in Dollar's colony (DLN) strain for alphamethrin. Similarly, the lowest LC50 value of 0.0041 mg/l was observed in Goruguntepalya (GGP) strain and the highest LC50 value of 0.0095 mg/l was recorded in J. R Nagar (JPN) strain for bifenthrin. For the neem, the lowest LC50 value of 0.0945 mg/l was observed in Punjab (PNJ) strain and the highest LC 50 value of 0.1257 mg/l for Hebbal (HBB) strain was recorded. The resistance ratio of LC50 ranged between 1.00 - 428.57, 1.00 - 2.32 and 1.00 -1.33 for alphamethrin, bifenthrin and neem respectively. The values of 1-C50, LC90, regression equation, correlation of coefficient, X2 and resistance ratio of insecticides on each strain were calculated and presented.
