- Relative capture of Caribbean fruit fly (Anastrepha suspensa (Loew)) by modified McPhail and Jackson traps was examined under fall and spring population densities. The influence of trap duration (one week compared with several weeks) also was examined. Standard McPhail traps were superior to all other designs at spring population densities (low). At fall population densities (high), the standard McPhail, solid orange Jackson trap, and the "umbrella" McPhail were equally effective for female and total trap catch. There was no significant difference in male trap catch during the fall. Because there was significant weekly variation in trap catch, trap evaluations need to be done over long periods of time.
