Considering the necessity of omission of monocrotophos from tobacco budworm, Helicoverpa armigera, control program, tests were carried out to assess the effect of indoxacarb, as an alternative in years 2005-2006. The experiments were conducted at randomized complete block design, using indoxacarb (Avant SC 15%) at rates ranging 200, 250, and 300 ml/ha, and conventional insecticides thiodicarb (Larvin DF 80%) at rate of
1 kg/ha and monocrotophos (Nuvacron SL 40%) at rate of 2 l/ha. Percent mortality was calculated using Henderson-Tilton formula at 1 and 3 days after spraying. A repeated-measures analysis, general linear model (GLM), indicated a significant difference among treatments for percent mortality of budworm. Both indoxacarb and thiodicarb caused a high mortality of the larvae, whereas monocrotophos revealed the lowest effect. In general, Avant SC 15% at the rates between 200 and 250 ml/ha is recommended for controlling tobacco budworm
