An experiment was conducted at Spices Research Centre, Bogra during the kharif season of 2012 to evaluate the IPM package for the better management of chilli fruit borer (Spodoptera litura). The lowest infestation (0.39 %) was observed in sex pheromone + bio-control agent treated plot which was significantly differed from all other treatments. The highest percentage (79.79) of fruit infestation reduction over control was also found from sex pheromone + bio-control agent treated plot followed by spinosad treated plot (45.07) and quinalphos treated plot (37.30). The result of fruit infestation also reflected on chilli yield. Highest yield was recorded from sex pheromone + bio-control agent treated plot (12.46 t/ha) followed by spinosad treated plot (6.73 t/ha) and quinalphos treated plot (6.20 t/ha).

To find out the IPM package for the management of chilli fruit borer (Spodoptera litura).
The field experiment was conducted at SRC, Bogra during Kharif, 2012 to evaluate the IPM package against pod borer (Spodoptera litura) in chilli. The experiment was laid out in a randomized complete block design with the three disperse replications keeping biological control treatment far away from chemical treatments. The test crop was chili advanced line C00517. Treatments were T1=Pheromone trap + sequential release of boi-agent (Trichogramma chilonis + Bracon hebetor); T2= Farmers practice (spray of quinalphos 25 EC@ 1ml/l of water first spray was done during pre-flowering stage and second spray after pod formation stage); T3= Spraying of bio-pesticide spinosad @ 0.4ml/l of water at pre-flowering and post flowering stages; T4= untreated control. Seedlings were transplanted on 10 March 2012.Unit plot size was 4m × 3m and spacing was 50cm X 50cm. The pheromone trap was placed just above the crop canopy by means of a bamboo support. All recommended agronomic practices were followed for production of chilli. The first spray was done at pre-flowering stage. Yield data of green chilli were recorded .Data on fruit infestation and yield were taken and analyzed using MSTAT program and mean values were separated by DMRT.

The above study revealed that pheromone trap + sequential release of boi-agent (Trichogramma chilonis + Bracon hebetor) were most effective in controlling spodonia catterpillaer (Spodoptera litura) in chilli with higher yield followed by spinosad and quinalphos.
