What you should know about stink bugs and leaffooted bugs

The adults of stink bugs have piercing and sucking mouth parts and feed on plant juices. Feeding by adult stink bugs prior shell hardening results in a condition known as "black pit" and will cause nuts to abort. After shell hardening, nuts stay on the three but black spots form on the kernel at the feeding site. Kernels with black spots have a bitter taste and are considered inedible.

Several species of leaffooted bugs are associated with pecan. Prior to shell hardening, feeding on nutlets by these insects causes a condition referred to as "black pit" also, which causes nutlets to abort. This same condition is also caused by several species of stink bugs as mentioned before. After hardening, it is thought that feeding by leaffooted bugs is restricted to the shuck with little or no kernel spotting.

Stink bug damage, notice the "black pits" produced by the insect.
