  Chick pod borer, Heliothis viriplaca Hufn, is an important pest of chickpea in East Azarbaijan province. In recent years, pesticides harmful effects have become a problem. This matter is also true regarding chemical control of chickpea pod borer. Therefore, the efficacy of some insecticides such as Indoxacarb Sc15%, Indoxacarb Ec15%, Pyridalyl Ec 50%, Carbaryl Wp 85% with a control (only water) against chickpea pod borer, was evaluated in Maragheh, East Azarbaijan during 2007-2008. The experiment was carried out with ILC 482 variety in RCBD design with three replications. Sampling and counting of live larvae was done 1 day before and 1, 3, 7 and 12 days after treatment by randomly selecting 20 plants from four middle rows  in each plot  and at the end of the experiment, the number of total pods and damaged pods in 20 plants of each plot was determined. The results of 7th and 12th days after insecticides application showed a significant difference among treatments at level of 5%. Indoxacarb Ec 15% (200 ml/ha) and Indoxacarb Sc15% (200 ml/ha) were both the most effective treatments followed by Piridalyl EC 50% (150 and 200 ml/ha) and Carbaryl wp 85%. Manuscript profile

  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. Manuscript profile

  The pod borer, Heliothis viriplaca Hufn., is one of the most serious pests of chickpea in the Middle East countries. For the life cycle studies, determination of different larval stages and other behavioral activity, the pupae were collected from cultivated fields and reared under laboratory conditions (25±2°C, %70±5 RH and 14/10 L:D). The laboratory test showed that this pest has one generation per year with obligate diapause. By measuring of head capsule width determined five larvae instars for the pest, with the ranges of 0.423, 0.699, 1.29, 1.84 and 2.64 mm respectively. It has been also indicated that larvae have high cannibalistic tendency under unsuitable conditions so that the larger larvae feed on other small larvae and prepupation stage. In addition the laboratory trials revealed that although all pupae held in 2±1°C condition for 30 days emerged, average      oviposition of females decreased and most of the eggs did not hatch.
