Info Bulletin: Honey Locust Plant Bug

Symptoms

  • Alteration in leaves
  • Smaller size of leaflets
  • Discoloration of leaves
  • Little irregular holes in leaves
  • Yellow to brown spots

Causes

Once in a year, the honey locust plant bug develops its one generation. Honey locust plant is the food of both young and adult bugs. Eggs are given below the bark on the branches and are hatched when the buds of the honey locust start to open. The unfolded leaflets become the next destination of the young nymphs and they start feeding on them. As the bug hides itself so, the actual damage to the plant start happening. The bugs penetrates their stylets in the small leaves that are extremely sensitive to irritation. The stylets thus destroy the plant cells. Nymph takes 30 days to develop into an adult bug and females begin to lay eggs soon after.

Treatment

Pesticides have been developed to treat the plants under attack of honey locust plant bug. The time to sprinkle pesticides is the spring season when the buds of the honey locust are just beginning to open. One of the pesticide options is a nontoxic soap, although sometimes several applications are required.
