The pod borer Heliothis viriplaca Hufn is one of the most serious pest of chickpea in the west of Iran. In this research the effect of Carbaryl, Diflubenzuron and Bacillus thuringiensis var.independently and in different combinations were tested against Helicoverpa viriplaca Hufn. in the field. Experiments were conducted at randomized block design. No significant different was observad between Bt, mixture of Carbaryl and Diflubenzuron, mixture of Carbaryl and Bt, mixture of Carbaryl, Diflubenzuron, Bt and Carbaryl treatments (p£0.01). All 7 treatments were effective on the number of damaged pods, yield and 1000 seed weight. The non sprayed blocks had the highest percentage of damage (30%). The minimum amount of yield was obtained in treatment of Diflubenzuron (922 kg/ha) and checks (with mean 911.42 kg/h), the highest weight of 1000 seeds with 361.07 and 364.6 g from other treatments, respectively. These results showed that treatments had significant effect in the first 24 hours after spraying to control the pest and increase the yield. Although Carbaryl and mixture of Carbaryl and Diflubenzuron, had high mortality on the pest after 24 hours, no significant effect on the yield increase was observad.
