Females drill a hole in the soft growing pecan to lay her eggs. The larva grows and chews a hole through the hard pecan shell. Best control is spraying every week from August 15th to September 15th for three years.

White, dusty powder on the pecan. Control is spraying the complete tree several times during the growing season.

Punctures nuts both before and after shell hardening. Either the pecan falls off prematurely or black spots appear on the mature pecan meat.

They show up on the tree late summer. However you have to control them in the spring, March and April. Does not hurt the pecan harvest but makes the tree look unhealthy.

Girdles eat twigs and small branches in September.
