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 most characteristic symptom of HLB is blotchy mottling that appears asymmetrically on the leaf blade. Green islands may also occur; these are small, circular, dark green dots that contrast with the light yellow/green background. Foliar symptoms that resemble nutrient deficiencies may be present. A tree may exhibit yellow shoots or other nutrient deficiency symptoms on one or more branches randomly in the canopy. Fruit may be small and lopsided or ripen backward, with the stylar end remaining green as the fruit colors.

Management tips: Citrus greening has not been found in Alabama to date. If citrus greening is suspected, contact your local diagnostic lab.
