Abstract/ Executive Summary:

A field experiment was conducted at the Farmers field of Gangachora, Rangpur during the year of 2011-12 for evaluating IPM package against leaf eating caterpillars of cabbage. Results revealed that IPM package (weekly release of egg parasitoid Trichogramma evanescens and larval parasitoid Bracon hebetor + use of Spodoptera litura pheromone trap) offered 86.03% reduction of head infestation and 8.2% higher yield over Non IPM package.

Keywords: Cabbage, IPM package, Leaf eating caterpillars

Location: Rangpur

Start Date: 10-11-2011

End Date: 05-02-2012

Program Area: Pest Management

Commodity: Cabbage

Objectives:

To evaluate IPM package for the management of leaf eating caterpillars of cabbage
To produce insecticide free cabbage.

Methodology:

The experiment was carried out at the Farmers field of Gangachora, Rangpur during the year of 2011-12 for evaluating IPM package against leaf eating caterpillars of cabbage. There were two treatments viz. T₁= IPM package comprising of weekly release of egg parasitoid Trichogramma evanescens(@ 1 gm parasitized eggs/ha/week) and larval parasitoid Bracon hebetor (800-1000 adult/ha/week) & use of Spodoptera litura pheromone trap(at 10 m² distance ), T₂= Non IPM : Farmers practice (spraying of Proclaim 5SG 4 times and Dursban 20 EC 3 times). The experiment was laid out with 6 dispersed replications. Farmers practiced plots were taken 500m away from the IPM plots. The number of healthy and infested heads were counted and recorded from randomly selected 2m² area of each treatment. Number of Spodoptera litura caught in the pheromone traps also recorded.
