Field trials of lures to attract fruit flies (Diptera: Tephritidae) in commercial sapodilla, mamey sapote, and carambola orchards in Puerto Rico

Field trials in Puerto Rico were conducted to compare the attractiveness of the standard bait of pelletized torula yeast with a two component (ammonium acetate and putrescine) synthetic lure for Anastrepha spp. within sapodilla (Manilkara zapota Van Royen), mamey sapote (Pouteria sapota (Jacq.) H.E. Moore & Stearn), and carambola (Averrhoa carambola L.) orchards. In addition, the trapping was conducted to provide information on the fruit fly pressure and species composition within the 3 fruit crops. Significantly more female and male fruit flies were collected over the entire collection periods in traps containing torula yeast when compared with the two component synthetic lure in sapodilla and mamey sapote. For both lure types, there was a distinct female bias for the sex ratio of flies captured. Fruit fly pressure within sapodilla was extremely high with approximately 30 A. suspensa collected per trap per day; in contrast, only 0.12 flies per trap per day (approximately 1:1 ratio, A. suspensa: A. obliqua) were found in mamey sapote. Trapping in carambola is still ongoing.

Species 1: Diptera Tephritidae Anastrepha suspensa (Caribbean fruit fly)
Species 2: Diptera Tephritidae Anastrepha obliqua (West Indian fruit fly)
