| Abstract:
Several trap types were tested to determine their relative efficiency in monitoring the olive fruit fly at 3 sites in California. During the 2003 field season, ChamP yellow sticky traps were compared to IMPT plastic McPhail traps. There were no significant differences between the ChamP and IMPT traps for dates in the cold winter months of the 2003 field season, but during this time period fewer than 1 olive fruit fly per trap per day were caught in either trap type. In 2004, ChamP, IMPT, and 3 variations of AM traps were compared at the same locations. In all cases where significant differences were found between traps, the IMPT traps outperformed all other trap types. Changes in trap efficiency over time, by fly sex, and between locations are discussed as well as the implications of these findings for monitoring programs. | |
