Abstract: The evaluation of Bacillus thuringiensis toxic effect can be made with O strinia Furnacatis. The best material for the test is the 2nd instar larvae. The test method is to mix B. T. preparations with the artificial medium first and then to infect the insect with this mixed product. The result is accuracy and with 15.49% of standard deviation. This method is simple and can be done easily. The test cycle is only 3 days
