Abstract/ Executive Summary:

A field survey was carried out in three maize growing areas of the country during 2006-2007 to record the status of insect pests attacking maize and their associated natural enemies. Cut worm (Agrotis ipsilon Hufnagel), pink stem borer (Sesamia inferens ), corn ear worm (Helicoverpa spp) and aphid (Rhopalosiphum maidis) were found to attack the crop at different growth stages at different locations. Although the rate of infestations were still non-significant. Micraspis discolor was the predominant lady bird beetle species in all the locations

Keywords: Survey, insects, maize, damage severity, natural enemies

Location: Bogra, Rajshahi and Manikganj

Start Date: 25-10-2006

End Date: 30-03-2007

Program Area: Pest Management

Commodity: Maize

Objectives:

1) To document the damage severity of insect-pests attacking maize 2) To identify the natural enemies of insects pests of maize 3) To obtain farmers’ perception on the attack of insect pests of maize along with their management practices

Methodology:

Three maize growing areas of the country viz. Bogra, Rajshahi and Manikganj were visited at the three crop growth stages (seedling stage, vegetative growth stage and the cob bearing stage) to collect data on the severity of insect pest problems of maize along with their natural enemies. In each location 3 plots (around 600 sq-m) were randomly selected. During the seedling stage 10 rows were randomly selected in each plot for collecting data on soil pests e.g. cutworm. Percent cutworm infestation was calculated by counting the number of cut plants and healthy plants in a particular row. At the vegetative growth stage and cob bearing stage 10 plants were randomly selected from each plot for recording data on other insect pests and natural enemies.
