The Mexican bromeliad weevil, Metamasius callizona Chevrolat 1882 (Coleoptera: Curculionidae), is an adventive pest of bromeliads native to Florida. Native epiphytic bromeliads are considered highly desirable elements of the flora, and many are now threatened or endangered due to this invasive pest. As part of a larger project focused on biological control of M. callizona, a trapping system is desirable to locate populations in the field for release of natural enemies. As the initial step for trap development, the orientation behavior of adult male and female M. callizona was examined in response to plant-herbivore complex odors using a Y-tube olfactometer.
