Establishment of a standard test method for determining susceptibility of Mesocyclops to different insecticides.
A method to determine the susceptibility of Mesocylops sp. to insecticides was devised. Matured adults were used for the bioassays. Mesocyclops sp. (25 in number) were placed in 24.9 ml of sterilized paddy field water in 5 cm diameter petri dish and 0.1 ml of appropriate stock solution of the insecticide was added. Mortality was scored 24 h after treatment. Among the insecticides tested, Permethrin, Dichlorvos, Temephos, DDT, Carbendazim, Fenitrothion, Zolone and Aldrin were effective against Mesocyclops sp.
