*This is an excerpt from Insect Pest Scouting for Crucifer Crops, ANR-2241

Identification

Brightly colored bugs with piercing-sucking mouthparts (orange, red, and yellow patterns on adults); eggs are barrel-shaped with black bands on top; overwinter as adults.

Plant Injury

Nymphs and adults feed on leaf veins causing extensive browning or wilting of leaves; extensive feeding will cause plants to wilt and die.

Sampling Method & Economic Threshold

  • Look for colorful adults or masses of nymphs feeding together.
  • ET (Georgia) = 1 adult bug per 10 plants.

ET = Economic Threshold (number of insects above which there will be economic losses)

Sampling Method & Economic Threshold

  • Use a good quality magnifying lens when scouting seedling.
  • Shot-hole leaf injury is distinctive.
  • Scout on field edges that usually get the worst damage from flea beetles.

The Home and Market Garden (Urban Farm) IPM Toolkit wheel slide chart is a great tool for urban farmers as well as home and community gardeners interested in vegetable production.

This wheel slide chart has both conventional and organic insecticide listings for nearly 20 different crops. It also has a listing of common insect pests with accompanying images that may help when scouting in garden vegetables.

To receive copy of this wheel slide chart, email Ayanava Majumdar at azm0024@aces.edu.

For growers or gardeners that are looking for organic only options, refer to the Alternative Vegetable IPM Recommendations Slide Chart, which describes the three levels of sustainable integrated pest management practices.
