Resumo
This research evaluated the effects of two products
based on Bacillus thuringiensis in the mortality rate of first and
third instar caterpillars of Spodoptera eridania, in laboratory
conditions, at 25±2°C, relative humidity 70±5%, and photoperiod
of 12 hours. The treatments were B. thuringiensis kurstaki (Dipel
SC), at 500 mL.ha-1, 750 mL.ha-1, and 1000 mL.ha-1; and B.
thuringiensis aizawai (XenTari) at 200 g.ha-1, 400 g.ha-1, and 600
g.ha-1, both in a 200 L.ha-1 spray solution, using distilled water
as control. The mortality rate was evaluated at 3, 6, 12, 18, 24,
36, 48, 60, 72, and 84 hours after infestation. After 84 hours, the
treatments with B. thuringiensis reached 80% of mortality on
caterpillars of the first instar. In the same period, the third instar
caterpillar mortality rate was 100%.
