ECOLOGY AND BEHAVIOR Field Trials of Solid Triple Lure (Trimedlure, Methyl Eugenol, Raspberry Ketone, and DDVP) Dispensers for Detection and Male Annihilation of Ceratitis capitata, Bactrocera dorsalis, and Bactrocera cucurbitae (Diptera: Tephritidae) in Hawaii

SolidMallet TMR (trimedlure [TML], methyl eugenol [ME], raspberry ketone [RK]) wafers and Mallet CMR (ceralure, ME, RK, benzyl acetate) wafers impregnated with DDVP (2,2dichlorovinyl dimethyl phosphate) insecticideweremeasured in traps as potential detection andmale annihilation technique (MAT) devices. Comparisons were made with 1) liquid lure and insecticide formulations, 2) solid cones and plugs with an insecticidal strip, and 3) solid single and double lure wafers with DDVP for captures of Mediterranean fruit ßy, Ceratitis capitata (Wiedemann); oriental fruit ßy, Bactrocera dorsalisHendel; and melon ßy, B. cucurbitaeCoquillett. Bucket and Jackson traps were tested in a coffeeplantationnearEleele,Kauai Island,HI (trials at highpopulations) andavocado orchards near Kona, HI Island, HI (trials at low populations). Captures of all three species withMallet TMRwere not different fromMallet CMR; therefore, subsequent experiments did not includeMallet CMR because of higher production costs. InMAT trials near Eleele, HI captures in AWPM traps with Mallet TMRwafers were equal to any other solid lure (single or double) except theMallet MEwafer. In survey trials nearKona, captures ofC. capitata,B. cucurbitae, andB. dorsaliswithMalletTMRwafers were equal to those for the standard TML,ME, and C-L traps used in FL and CA. A solidMallet TMR wafer is safer, more convenient to handle, andmay be used in place of several individual lure and trap systems, potentially reducing costs of large survey and detection programs in Florida and California, and MAT programs in Hawaii.
