Abstract: An experiment was carried out to find out the suitable chemicals for the control of termites in tea plantations in Bangladesh. Efficacy of eight insecticides - Admire 200 SL, Direx 80 SP, Regent 50 SC, Talstar 2 WP, Nitro 505 EC, Nize 20SP, Supertrap 50 SP and Actara 25 WG were tested against termite infesting tea under field condition at the main farm of Bangladesh Tea Research Institute. All the insecticides were found to be effective with more than 80% efficiency for the control of termites. Tea yield was significantly higher in Admire 200 SL treated plots @ 1.5 L ha-1. Admire 200 SL treated plots showed 85.99% efficacy against termites in the experimental stations over the control plots. The chronology of effectiveness of different termiticides was Admire 200 SL > Direx 80 SP > Regent 50 SC > Talstar 2 WP > Nitro 505 EC > Nize 20 SP > Supertrap 50 SP > Actara 25 WG. Considering economic point of view, Actara 25 WG showed highest marginal rate of return (5741.66%) followed by Admire 200SL (775.71%), Nize 20SP (709.02%), Direx 80SP (571.74%), Regent 50SC (461.04%), and Supertap 50SP (218.32%). So, Actara 25WG @ 0.2 kg ha-1 might be the most economically acceptable insecticide for controlling termite pests of tea garden in Bangladesh.
