Stinkbugs

The three main stinkbug pests in Delaware that cause damage to vegetables, fruits, and field crops are the recently introduced brown marmorated stink bug, native brown, and native green stinkbugs.  Read about stinkbugs in corn by clicking here:  http://agdev.anr.udel.edu/weeklycropupdate/?p=4332 The three species are pictured below (photos by P. Sylvester).

Brown Marmorated Stink Bug Adult.  Note the white bands on the antennae and the alternating white and black bands on the edges of the abdomen.

Brown Stinkbug.  While similar in appearance to the brown marmorated stink bug, the brown stinkbug does not have white bands on the antennae.  Another distinguishing feature is the light colored, yellowish underside of the native brown stinkbug versus the gray underside of the brown marmorated stink bug.
Green Stinkbug.

Know Your “True Bugs” That Are Pests of Crops

August 7, 2007 in Uncategorized

The insect order Hemiptera is commonly referred to as the “True Bugs”. There are some very important agricultural pests in this group and we are seeing more of them as the summer advances. This includes brown and green stinkbugs in soybeans, tomatoes, and other fruit and vegetable crops; harlequin bugs in cole crops; Lygus (tarnished plant) bugs in lima beans; squash bug on pumpkins, winter squash, and summer squash; and aphids of many types in many crops. These all are piercing-sucking insects and do damage to plants by inserting their needle-like stilet into the plant tissue and sucking up the plant sap. They have an incomplete metamorphosis, that is they hatch from eggs into a nymph which completes several molts before becoming the adult form.
