Plant Injury

Can be a major problem early on because it severs seedlings while living at the soil-air interface; beetles are very attracted to grassy crops or weedy landscapes

Sampling Method & Economic Threshold (ET)

  • Deploy germinating seed bait stations (wheat-corn mixture) at several locations in fields with a history of wireworm attack.
  • Use soil cores (sample around small tomato seedlings/transplants) and wash the dirt to recover larvae. Use larval size and number as an indicator of life stage and insect pressure.
  • ET = 1 wireworm per seed bait (average from several baits across a field)

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

Plant Injury

Leaves are damaged but fruits are spared; minor pest

Sampling Method & Economic Threshold (ET)

  • Study the leaves directly from 10 plants per location and look for larvae (cabbage looper larvae have two pairs of abdominal prolegs).
  • Look for fecal pellets on leaves.
  • ET = 5 looper larvae per 10 plants at any plant stage or defoliation greater than 20%

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

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.
