Honey Locust plant bug (194) Diaphnocoris chlorionis family Miridae |

| Monitoring | Control Options | Pesticides |
|
Larvae: As leaves begin to unfold in spring, check carefully for the presence of immature insects hidden inside. Look for distorted or stunted leaves somewhat later. Larvae: Look for adults in June and July. |
Chemical: For large populations of larvae present at budbreak, spray with horticultural oil (1%) or use a residual insecticide. Large populations of adults in June and July can be treated with oil (2%) or a residual insecticide. |
horticultural oil chlorpyrifos cyfluthrin |
| Description and Life History | ||
|
Description: Adults are pale green bugs about 5-6mm long. Immature insects are the same color but smaller, and whereas the adult has wings, which it holds flat across its back, the immature bug has only short wing buds. Life history: Eggs hatch as honeylocust leaf buds begin to open and larvae feed on the leaves as they unfold. Adults appear in June and are present through July. There is one generation a year. Overwintering: Eggs overwinter under the bark of 2-3 year old twigs. | ||
