Abstract:

In the present investigation, differential response was observed in different populations of L. orbonalis with respect to six different pyrethroids, viz., alphamethrin, cypermethrin, deltamethrin, fenvalerate, λ-cyhalothrin, and fenpropathrin. The Kolar population was found to be most susceptible to alphamethrin, deltamethrin and λ-cyhalothrin with LC50 values of 0.01, 0.02 and 0.02 ml/l, respectively, while Belagavi and Bengaluru and Koppal population were recorded most susceptible to cypermethrin, fenvalerate and fenpropathrin, LC50 values ranged from 0.04 to 0.13 ml/l. The results also suggested different pyrethroids use pattern in different places, among different populations, Koppal population was found 24-fold resistant to alphamethrin, Belagavi population was 12-fold resistant to deltamethrin, Bengaluru population was 10.5-fold resistant to λ-cyhalothrin and Belagavi population was 2.5-fold more resistant to fenpropathrin. However, all populations were found to be highly susceptible to cypermethrin and highly resistant to fenvalerate as LC50 values ranged from 0.13 to 0.26 ml/l for different populations.
