Plants in pest control
Apply a drop or two to the tip of corn ear after the silks have wilted. Mineral oil prevents corn earworm from crawling down into the husk to feed (Ellis; Bradley, 1996: p. 477).
- Pheromone traps
To make your own trap, use 1-liter ice cream containers. Cut 3 large holes into the sides of the container for the insects to enter. Fill the bottom half with soapy water. Suspend the pheromone capsule from the lid using string or wire then snap the trap closed. Attach the trap to a bamboo pole or stake (Ellis; Bradley, 1996: p. 437). Buy the pheromone vial from agricultural suppliers.
- Light traps
Put light traps in strategic areas in the field to catch adults. Moths are attracted to light.
- Bird perches
Erect bamboo/wooden poles as bird perches at regular intervals inside the cornfield. These provide resting places for birds. Birds resting on these perches are attracted to worms (CIKS, 2000)
