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

Causes serious damage to blossoms and fruits similar to that of stink bugs. Also introduces yeast inside fruit during deep probing.

Sampling Method & Economic Threshold (ET)

  • Influx of these insects appears to be heavy during July and August. Trap crops of sunflower and sorghum (refer to Alabama Vegetable IPM website) allow early detection of bugs.
  • Scout for egg masses that may be laid in a row on fruits, leaves, and plant stalks.
  • Distribution of bugs can be highly clumped.
  • ET = unknown in tomatoes; follow stink bug recommendation.

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.
