Abstract/ Executive Summary:

Efficacy of three types of pheromone lures were evaluated against Spodoptera litura as well as its management package was developed in mustard at Chalan Bill area of Tarash, Sirajganj during 2009-10 and 2010-11 cropping seasons. Among the three lures, CSA (Chineese Science Academy) lures attracted and trapped significantly higher number of S. litura, followed by TARI (Taiwan Agricultural Research Institute) and Viroyal, Greece lures. During both the years, pod infestations in IPM fields were almost nil, while the infestation in non-IPM fields were 42.8 and 37.6% during 2009-10 and 2010-11 cropping seasons, respectively. Yield increase was 2.0 times higher in IPM plots than non-IPM plots. On the other hand, pest management cost was 2.5 times less in IPM plots than the non-IPM plots

Keywords: IPM package, Prodenia caterpillar, mustard

Location: Tarash, Sirajgonj

Start Date: 15-11-2010

End Date: 24-02-2011

Program Area: Pest Management

Commodity: Insects

Objectives:

To Know the efficacy of three types of pheromone lures against Spodoptera litura in mustard

Methodology:

This experiment was conducted in the mustard field of Chalan Bill area at Tarash upazilla, Sirajganj during 2009-10 and 2010-11 cropping seasons. Two sets of experiments were set. In the first set, the efficacy of pheromone lures and traps were evaluated and in the second set, several management packages were evaluated. The treatments were: T₁ = Pheromone trap + Sequential release of bio-control agents (Trihograma chilonis + Bracon hebetor) T₂= Farmer’s practice (Spray with Quinalphos @ 1ml./l of water at an interval of seven days). Data on percent pod infestation by S. litura, yield and pest management cost were calculated and recorded.
