Technical Abstract: The host list for the Caribbean fruit fly, Anastrepha suspensa (Loew), includes nearly 100 fruit trees including citrus. In south Florida, it is primarily a pest of dooryard fruit trees including Surinam cherry, Eugenia uniflora; loquat, Eriobotrya japonica; and tropical almond, Terminalia catappa; and it is a production pest of common guava, Psidium guajava. In areas of Florida with commercial citrus production, fly-free zones are designated areas that are certified as A. suspensa controlled areas for citrus export. In addition to Florida, A. suspensa is found in Cuba, Jamaica, Hispaniola and Puerto Rico. Highly effective traps for this species and for other Anastrepha spp are needed for suppression of fruit flies in areas in which they occur and for early detection in areas currently free of these pests. McPhail-type traps baited with a two component food-based synthetic lure containing ammonium acetate and putrescine outcapture McPhail-type traps baited with the liquid protein baits Nulure/borax or torula yeast/borax in some field trials, but results may be highly variable among different host plants or different environmental conditions. We will report on the results of laboratory and field tests conducted to further evaluate the effects of ammonia dose and formulation on A. suspensa response, as well as comparative studies with other liquid protein bait types and formulations.
