How to Manage Pests

Pests in Gardens and Landscapes

Stink bugs

Stink bugs, family Pentatomidae, are shield shaped with a large scutellum or triangle on their backs. Bugs may be brown or green. They are wider than most other true bugs and are named because of the offensive-smelling defensive chemical some species give off when disturbed. Stink bug eggs are barrel shaped with distinct circular lids and are usually laid in groups of ten or more on leaf surfaces.

Most stink bugs are pests of vegetable or herbaceous plants. The consperse stink bug, Euschistus conspersus, attacks stone fruit and pear trees, causing discolored depressions, blemishes, or dark pinpricks on fruit. Damaged areas beneath spots on fruit become white and pithy but remain firm as fruit ripen. Except for fruit, woody plants are not harmed by stink bug feeding.
