Pecan phylloxera

Phylloxera spp.

Phylloxeras are tiny, cream colored to pale yellow insects that resemble aphids but lack cornicles (the tubes found on the rear end of aphids). They have sucking mouthparts and are 1/ 10 to 1/5 inch long. Their feeding stimulates the plant to produce galls on the leaves, stems, and nuts. The phylloxera reproduce inside the galls. There are three species on pecans in Oklahoma.
