Field Evaluations of Pheromone-Baited Traps for Monitoring Mexican Rice Borer (Lepidoptera: Pyralidae)

Abstract

The Universal Moth Trap (Unitrap) caught more male Mexican rice borers, Eoreuma loftini (Dyar), than 13 other trap types. Traps placed 5 m within sugarcane fields captured significantly more male Mexican rice borers than traps at the edge of the field or 5 m outside the field. Traps at the edge of the field captured significantly more insects than traps placed 5 m outside the field. There were no significant differences in trap captures when Unitraps were placed 5 m inside the field at heights of 46, 102, or 158 cm aboveground, but captures were less in traps placed 214 cm aboveground. With Pherocon IC traps placed 5 m inside the field, there were no significant differences in trap captures of male Mexican rice borers at any of the four heights.
