Abstract/ Executive Summary:

A field experiment was conducted at Fruit Research Farm of Horticulture Research Center, BARI, Gazipur during March to July 2010 to find out effective, easy and eco-friendly management strategies against the fruit borer, Virachola isocrates. There were five treatments in the experiment viz. T₁= Wrapping of fruits by waxy paper, T₂ = Wrapping of fruits by used cloths, T₃ = Wrapping with perforated poly bags, T₄ = Hand picking + Inundate release of bio-control agent, Trichogramma chilonis @ 200 adults and Bracon habetor @ 20 adults per plant and T₅ = Control. Result indicated that wrapping of fruits by waxy paper (T₁) and wrapping of fruits by used cloths (T₂) trees performed 100% reduction of fruit borer damage.

Keywords: Management approaches, Fruit borer, Pomegranate.

Location: Fruit Research Farm of Horticulture Research Center, BARI, Gazipur

Start Date: 01-03-2010

End Date: 31-07-2010

Program Area: Pest Management

Commodity: Pomegranate

Objectives:

To find out easier and cost effective management approaches for pomegranate.

Methodology:

The experiment was conducted at Fruit Research Farm of Horticulture Research Center, BARI, Gazipur during March to July 2010. The experiment was laid out following Randomized Complete Block Design (RCBD) with three replications. One tree served as a replication. There were five treatments in the experiment viz. T₁ = Wrapping of fruits by waxy paper, T₂ = Wrapping of fruits by used cloths, T₃ = Wrapping with perforated poly bags, T₄ = Hand picking + Inundate release of bio-control agent, Trichogramma chilonis @ 200 adults and Bracon habetor @ 20 adults per plant and T₅ = Control. Wrapping of fruits was done at marble size of fruits. Hand picking and inundate release of bio-control agent, Trichogramma chilonis and Bracon habetor release were started from first appearance of pest. Data were recorded on number of infested and healthy fruits per plant.

Achievement/Findings:

In order to find out easier and cost effective management approaches against fruit borer in pomegranate, five treatments viz. T₁ = Wrapping of fruits with waxy paper, T₂ = Wrapping of fruits by used cloths, T₃ = Wrapping with perforated poly bags, T₄ = Hand picking + Inundate release of bio-control agent, Trichogramma chilonis @ 200 adults and Bracon habetor @ 20 adults per plant and T₅ = untreated control were evaluated. Results of the study revealed that wrapping of fruits with waxy paper as mentioned in treatment T₁ and wrapping of fruits with used cloths as mentioned in treatment T₂ protected 100% fruit borer damage in pomegranate. Fruits wrapping with waxy paper or used cloths could be suggested as effective and eco-friendly management strategy against fruit borer in pomegranate.
