Evaluation of Methyl Eugenol and Cue-Lure Traps With Solid Lure and Insecticide Dispensers for Fruit Fly Monitoring and Male Annihilation in the Hawaii Areawide Pest Management Program

Abstract

Methyl eugenol (ME) and cue-lure (C-L) traps with solid lure dispensers were deployed in areas with low and high populations of oriental fruit fly, Bactrocera dorsalis (Hendel), and melon fly, Bactrocera cucurbitae (Coquillett), respectively. In low-density areas, standard Jackson traps or Hawaii Fruit Fly Areawide Pest Management (AWPM) traps with FT Mallet ME wafers impregnated with dimethyl dichloro-vinyl phosphate (DDVP) or AWPM traps with Scentry ME cones and vapor tape performed equally as well as standard Jackson traps with liquid ME/C-L and naled. Standard Jackson traps or AWPM traps with FT Mallet C-L wafers impregnated with DDVP or AWPM traps with Scentry C-L plugs with vapor tape performed equally as well as standard Jackson traps with a lure-naled solution. In high density areas, captures with traps containing FT Mallet wafers (ME and C-L) outperformed AWPM traps with Scentry cones and plugs (ME and C-L) with DDVP insecticidal strips over a 6-mo period. Captures of B. dorsalis and B. cucurbitae with wafers containing both ME and raspberry ketone (FT Mallet MC) were equivalent to those containing separate lures. From a worker safety and convenience standpoint, FT Mallet ME and C-L wafers with DDVP or Scentry plugs, with or without DDVP vapor tape, are more convenient and safer to handle than standard liquid insecticide formulations used for monitoring and male annihilation programs in Hawaii, and for detections traps used on the U.S. mainland. Furthermore, the FT Mallet MC wafer might be used in a single trap in place of two separate traps for detection of both ME and C-L responding fruit flies.

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

“…For example, Vargas et al (2009Vargas et al ( , 2010a identiÞed solid single and double lure insecticidal wafers and solid lure plugs and cones as promising substitutes for traps baited with liquid ME or C-L with naled (standard California and Florida detection Jackson trap). The plugs and cones have the advantage of being deployed with or without an insecticide if placed in escape proof traps (Hiramoto et al 2006).…”

Lethal and Sublethal Toxicity of Fipronil and Imidacloprid on Psyttalia concolor (Hymenoptera: Braconidae)

“…It can be mentioned as examples the control of Mediterranean fruit fly, Ceratitis capitata (Wiedemann), in Spain (Urbaneja et al 2009), several fruit flies in Hawaii (Vargas et al 2010), and olive fruit fly, Bactrocera oleae (Gmelin), in California (Sime et al 2006). Biological control with braconid parasitoids is one of the most environmentally friendly control strategies, but the most efficient method at present remains chemical control, which is routinely used worldwide (Liaropoulos et al 2005, Mazor 2009, Urbaneja et al 2009).…”

Response of Melon Fly (Diptera: Tephritidae) to Weathered SPLAT-Spinosad-Cue-Lure

“…or Hawaii Area Wide Pest Management (AWPM) traps baited with Mallet C-L wafers impregnated with DDVP performed as well as standard Jackson traps that were baited with liquid C-L and naled in a wick (Vargas et al 2009b(Vargas et al , 2010a. In the present study, captures of another C-L-responding fly, B. tryoni, in traps baited with the Mallet C-L wafer were comparable to traps baited with liquid C-L plus malathion in a wick only during the first 8 weeks, but subsequently captures with the Mallet C-L wafer much lower than with the liquid C-L formulation.…”
