Abstract/ Executive Summary:

Field studies were undertaken in the farmer’s field of Jessore region during 2008 and 2009 to evaluate IPM package against fruit fly and borer complex in bitter gourd. IPM package involving sanitation, use of sex pheromone trap, weekly release of egg and larval parasitoids along with community approach significantly reduced the populations of fruit fly and borer complex in bitter gourd.

Keywords: Bittergourd, IPM, cucurbit, fruit fly

Location: Jessore

Start Date: 02-03-2008

End Date: 12-06-2009

Program Area: Pest Management

Commodity: Bitter gourd

Objectives:

To develop a management package to control the fruit fly as well as borer complex of bitter gourd.

Methodology:

Studies were undertaken in the farmer’s field of Jessore region during 2008 and 2009 cropping season at Nongarpur, Jessore to evaluate IPM package against fruit fly and borer complex in bitter gourd. There were two treatments, IPM practice and Farmer’s practice. IPM practice consisted of sanitation (weekly removal of infested fruits), use of sex pheromone trap (trapping was started after flower initiation of the cucurbit crops), weekly release of egg parasitoid, Trichogramma evanescence (@ 1 gm parasitised eggs), larval parasitoid, Bracon hebetor (@ 1000-1200 adults) and community approach were practiced and in farmer’s practiced only insecticides were sprayed at 2-3 days interval. The experiment was set following RCB design with 4 dispersed replications. Data on fruit fly and different borer infestation from 4 randomly selected areas (1 m²)/treatment replicates were done at weekly interval after fruit setting and as well as during harvesting. Yield data were also recorded from both IPM and farmer’s practiced field.
