Abstract/ Executive Summary:

A comprehensive survey was conducted by extensive tour in Gazipur, Narsingdi, Comilla. Noakhal i,Barisal,Rangpur, Dinajpur and Jessore districts of Bangladesh to record the present status of pumpkin beetles infesting cucurbits. Results of survey revealed that two species of pumpkin beetles found on cucurbits in Bangladesh and they were identified as red pumpkin beetle, Aulacophora foveicollis (Lucas) and blue pumpkin beetle, Aulacophora atripennis. The red pumpkin beet le was the most abundant species which representing 82.39% and the blue pumpkin beetle was less abundant species which representing only 17.61% of the total number of beet les recorded during survey. Population of female was higher than that of male in both species. RPB was much larger insects as compared to BPB. In both insect species female adults are larger in dimension than males. The highest population of RPB was found on cucumber followed by bottle gourd and sweet gourd. The highest population of BPB was found on bitter gourd. The maximum population of RPB was in Gazipur followed by Narsingdi and Comilia districts and that of BPB was in Gazipur followed by Noakhali.

Keywords: Pumpkin beetles, Population, Cucurbits. Districts

Location: Eight different districts of Bangladesh (Gazipur, Narsingdi , Comilla, Noakhali, Barisal, Rangpur, Dinajpur and Jessore)

Start Date: 00-04-2007

End Date: 00-12-2008

Program Area: Pest Management

Commodity: Cucurbit

Objectives:

To find out present status of pumpkin beetle species infesting cucurbits and to know their incidence on the cucurbits in some selected areas of Bangladesh.

Methodology:

Eight cucurbit growing districts of Bangladesh namely Gazipur, Narsingdi , Comilla, Noakhali (Coastal area), Barisal, Rangpur, Dinajpur and Jessore were selected for this study. A comprehensive survey was conducted by extensive tour throughout the selected locations during both winter and summer seasons from April 2007 to December 2008. In the selected locations two or more cucurbits are grown every year. The selected locations were visited 2 times and pumpkin beetle infested cucurbit fields were observed in the morning and afternoon. In each survey location, three cucurbit fields were randomly selected. A total of 60 plants selecting 20 plants from each field were checked for recording the incidence of pumpkin beetles. Two species of pumpkin beetles were observed and identified as red and bl?ue pumpkin beetles. The specimens of red pumpkin beetle (RPB) and blue pumpkin beetle (BPB) of both sexes (male and female) were collected by hand picking. Some collected specimens were brought back to the Entomology Laboratory at BSMRAU for morphometric study.
