An experiment was conducted at research field of Entomology division, BARI, Gazipur, during Rabi 2012-13 to evaluate different bio-rational based IPM packages against pod borer infesting chickpea. IPM package (P2) comprising of sex pheromone trapping + sequential release of bio-control agents + spraying of HNPV revealed the best performance reducing 68.20% pod damage over control and provided significantly the highest yield (1832.20 kg/ha). Consequently, the highest benefit cost ratio (2.11) was also recorded from this package. Hence, bio-control agents release along with installation of sex pheromone traps and spraying of HNPV may be recommended for effective management of pod borer attacking chickpea.

Obtaining an effective IPM package against pod borer attacking chickpea.
The experiment was conducted at Entomology division, BARI, Gazipur, during Rabi 2012-13 to evaluate different biorational based IPM packages against pod borer infesting chickpea. The treatments were: IPM package 1 (P1)= Sex pheromone trapping + Sequential release of bio-control agents (Trichograma evanescens + Bracon hebetor) + Spraying of Bt @ 0.4g/ litre of water; IPM package 2 (P2)= Sex pheromone trapping + Sequential release of bio-control agents (Trichograma evanescens + Bracon hebetor) + Spraying of HNPV @ 0.1g/litre of water; Farmer’s practice (P3)= spraying of Nitro 505EC (Cypermethrin+Chlorpyriphos) @ 2ml/litre of water and Untreated control.The experiment was laid out in a randomized complete block design with three replications (dispersed). The treatments were randomly allotted in each block. The damaged (bored) and total numbers of pods were counted and the per cent pod damage was determined.
