Abstract

Females of Oncideres cingulata (Say) girdle small branches of mesquite, Prosopis glandulosa (Torr.) Cockerell, in September. Most progeny complete development within 1 year, though a small percentage of the mature larvae pass a second winter in the galleries of girdled branches. Generation mortality for O. cingulata is 99.2%. About 37% of the first-instar larvae are parasitized, and 53% of the mature larvae are preyed upon by birds. The cerambycids, Megacyllene antennata (White), Placosternus difficilis (Chevrolet), Taranomis bivittata (Dupont), and Oncideres rhodosticta Bates, and a bostrichid, Xylobiops texanus (Horn), are the chief competitors of O. cingulata for the small mesquite branches.
