Several kinds of stink bugs feed on tomatoes, but all are similar in life history and damage. Adults are distinctly shield shaped and either brown or green.
Some species have red, pink, or yellow markings.
Immatures resemble adults but do not have developed wings. Stink bugs also carry yeast and other pathogens that may cause decay when introduced into fruit on the bugs' mouthparts. Examine stink bug eggs to determine levels of parasitization. Trissolcus basalis does not appear to parasitize the native stink bugs in the field. If parasitized egg masses are found, treatment for newly hatched nymphs might not be necessary.
