A series of studies was conducted comparing the effect of trap type (pyramid, Circle and boll weevil trap top) and pheromone (boll weevil, pecan weevil or unbaited) on numbers of adult pecan weevil (PW), Curcurlio caryae Horn, captured in native orchards. Significant differences were observed between years and trap types; however, no significant advantage was observed from the addition of any pheromone. Results obtained from every test conducted revealed a significant advantage in using the Circle trap, in terms of total weevils captured, as well as early- and late-season capture of weevils.
