COMPARATIVE STUDY OF EFFICIENCY OF DDT AND MALATHION IN CONTROL OF ECTOPARASITIC TICKS ON DIFFERENT COW BREEDS OF INDIAN ORIGIN (BOS INDICUS) IN RUHAILKHAND AREA (UP)

摘要

Experiments were performed to investigate comparative effectiveness of different concentrations of DDT and Malathion in control of ectoparasitic ticks on different cow breads of Indian origin (Bos indicus) in "Ruhailkhand area" of U.P. (India). It was found that 20% concentration of both acaricides (DDT and Malathion) has no effect on tick infestation. As the concentration increased to 25%, 30%, 35% and 40%, a significant reduction in the infection of ticks observed. In the present investigation it has been observed that DDT and Marathon, both are equally effective as wash in control of tick infection on cows.
