The acaricidal activity and residual effects of 63 commercialized pesticides against the Cheongju strain of Haemaphysalis longicornis in Korea were examined. Twenty-two pesticides (4 carbamates, 5 organophosphates, 10 pyrethroids, 1 amitraz, 1 diamide, and 1 unclassified pesticide) caused greater than 80% mortality in H. longicornis adults under laboratory conditions using the spray method. These 22 pesticides were used to treat grassland under field conditions for investigation of the residual effects, and 100% mortality in H. longicornis adults was observed with all the carbamates (carbosulfan, benfuracarb, fenobucarb, and carbaryl) and gamma-cyhalothrin after 3 days of pesticide treatment. gamma-Cyhalothrin exhibited 56.7% mortality after 10 days of treatment, which was the longest residual effect of treated grass on H. longicornis adults. With regard to the residual effects on H. longicornis under field conditions, most of the 22 pesticides exhibited higher mortality in nymphs than in adults. In particular, benfuracarb exhibited 96.7% acaricidal activity until 10 days after treatment. These results indicate that carbamates are highly likely to be available under field conditions and, based on this preliminary data, could be used for the control of H. longicornis adults and nymphs.
