Abstract: The parasitism capacity of Trichogramma pretiosum Riley strain bonagota on Bonagota salubricola (Meyrick) eggs was studied under the temperatures of 18, 20, 22, 25, 28, 30 and 32ºC. The number of days with parasitism, accumulated parasitism, total number of eggs parasitized per female and parasitoid longevity was evaluated. In the first 24h, parasitism ranged from 1.6 (32ºC) to 8.8 (22ºC) eggs of B. salubricola. Accumulated egg parasitism of B. salubricola reached 80% in 1st to 4th day at 20ºC to 32ºC, respectively, and in the 7th day at 18°C. Temperatures from 18°C to 22°C were the best suited for the total eggs parasitized for female, resulting in 35.4 and 24.6 eggs/male respectively. T. pretiosum female longevity ranged from 7.8 to 2.5 days, at 18°C and 32ºC, respectively. The results showed that T. pretiosum strain bonagota is better adapted to temperatures from 18°C to 22ºC.
