“…A need to develop improved lures and “attract-and-kill” devices including bait stations for successful fruit fly control has already been recognized (IAEA, 2007; Heath et al 2009). The so-called Papaya Leaf Mimic (PLM), which represents a supernormal visual stimulus of papaya foliage, was developed in Hawaii in response to an imperative need to protect GF-120 against rainfall.…”

Bait stations represent an environmentally friendly attract-and-kill approach to fruit fly population suppression. Recently a novel, visually attractive, rain-fast bait station was developed in Hawaii for potential use against multiple species of pestiferous fruit flies. Here, we compared the efficacy of GF-120 NF Naturalyte Fruit Fly Bait applied either as foliar sprays or onto bait stations in reducing female oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), population density and level of fruit infestation in commercial papaya orchards in Hawaii. Trapping and infestation data were used as indicators of the effectiveness of the two bait application methods. For the first 10 weeks of the study, captures of female B. dorsalis in monitoring traps were significantly greater in control plots than in plots treated with foliar sprays or bait stations. Six weeks after the first bait spray, incidence of infestation (i.e. number of fruit with one or more B. dorsalis larvae) of quarter to half-ripe papaya fruit was reduced by 71.4% and 63.1% for plots with bait stations and foliar sprays, respectively, as compared to control plots. Twelve weeks after first spray, incidence of infestation was reduced by only 54.5% and 45.4% for plots with bait stations and foliar sprays, respectively, as compared to control plots. About 42% less GF-120 was used in orchard plots with bait stations compared to those subject to foliar sprays. The impact of field sanitation on the outcome is also discussed. The results indicate that bait stations can provide a simple, efficient, and economical method of applying insecticidal baits to control fruit flies and a safer alternative to foliar sprays.

“…The outside face of the trap (the snap-on cap) was covered with green tape to provide a visual cue, and it contained a 1.5-cm-diameter hole in the center to provide a point source release of volatiles from test substrate and a point of entry for the ßies. A wax matrix bait station strip (2.54 cm by 6.35 cm by 4 mm thick; Heath et al 2009) with 1% granulated sugar as feeding stimulant, 1% methomyl (Lannate, 90% [AI]; DuPont Ag Products, Wilmington, DE) as toxicant, and green food color as visual cue was placed in each trap to retain ßies that had entered. All ßies were sexually mature (11Ð13 d) and had been protein-starved for 24 h before the test.…”

At present, the most effective synthetic lures for pest Anastrepha fruit flies are multicomponent blends that include ammonia and the diamine synergist putrescine (1,4-diaminobutane). Both chemicals generally have been regarded as protein cues that result in female-biased attraction. Using electroantennography (EAG) and flight tunnel bioassays, this study evaluated response of the Caribbean fruit fly, Anastrepha suspensa (Loew) to vapors released from commercial lure formulations of ammonium bicarbonate and putrescine. Over a range of doses tested, EAG response to ammonium bicarbonate was equivalent for both sexes, but female response was significantly greater than male response to putrescine and to a 1:1 mixture of ammonium bicarbonate and putrescine. Amplitude of EAG response to the mixture was approximately equal to the summation of responses to the individual substrates. Using a fixed dose of substrate, EAG measurements from females 1-14 d old indicated that antennal sensitivity to both lures varied according to physiological state of the fly. Peak response to ammonium bicarbonate was recorded from immature females, peak response to putrescine from sexually mature females. In bioassays, more females were captured with ammonium bicarbonate plus putrescine than with ammonium bicarbonate alone. This difference was not observed in males, resulting in a higher female to male ratio in captures with ammonium bicarbonate plus putreseine (3:1) versus ammonium bicarbonate alone (1:1). Results suggest that separate olfactory receptors are involved in detection of the two semiochemicals, and that the putrescine component is primarily responsible for the female-biased attraction.

“…Capture of female insects beside males, on the other hand, would provide a better opportunity for: 1) more precise monitoring, leading to more accurate decision-making on timing of control strategies against a given pest species (Wall, 1985); 2) more efficient mass trap-ping by direct population reduction catching gravid females (Bakke and Lie, 1985), as reported, among others, for Ceratitis capitata Wied. (Diptera: Tephritidae) (Katsoyannos et al, 1999); 3) the application of the lure-and-kill method, as reported for example in Anastrepha suspensa Loew (Diptera: Tephritidae) (Heath et al, 2009); 4) efficacy assessment of the sterile male technique by determining egg sterility of captured females (e.g. in C. capitata, Miranda et al, 2001).…”

For acceptable capture efficiency it was necessary to add acetic acid to pear ester for successful trapping of codling moth populations in Hungary. The activity of pear ester on its own was very weak and unsatisfactory. Pear ester+acetic acid baited traps caught on an average 25% (mean of 6 tests) of the catch in pheromone traps. Traps with pear ester+acetic acid were clearly advantageous as compared to pheromone traps in that they caught not only males but also females (both virgins and mated) in a high percentage. Traps baited with pear ester+acetic acid clearly outperformed high-load pheromone lures in orchards with mating disruption and should be the right choice for the grower for sampling populations of codling moth in a mating disruption situation. In orchards with no mating disruption the relative inefficiency of pear ester+acetic acid baited traps as compared to pheromone traps can easily be overcome by applying more traps than usual. Thus the overall codling moth numbers caught will become higher and would make any conclusions drawn more reliable. Traps baited with pear ester+acetic acid always caught more when set at the highest branches (3.0-3.5 m) than when set lower (1.5-1.8 m) on trees.
