Ecotoxicity test was conducted to study the effect of Terakil-1® and Teracon-1® against freshwater fish Tilapia nilotica by exposing it to various concentrations of the sample. Terakil-1® and Teracon-1®, each led to 30% and 12.5% corrected mortality of freshwater fish, Tilapia nilotica at 128 mg litre-1 at 4 days after treatment (96 hr). The LC50 of two MPOB Bt1 products was 100-1000 mg litre-1 implying that Terakil-1® and Teracon-1® are practically non-toxic. Terakil-1® and Teracon-1® are target specific to palm insect pests such as bagworms and nettle caterpillars.
