AbstractMale spruce budworm moths were kept in a wind tunnel for 4 days and assayed each day to determine their ability to locate calling females that were surrounded by rubber septa loaded with synthetic pheromone, a 95:5 blend of E:Z-11-tetradecenal. As the concentration of synthetic pheromone increased, the numbers of males successfully locating females decreased, the latency of response increased, and the speed of flight decreased. At release rates from the septa close to those of a calling female, 6–60 ng/h per septum, most disrupted males flew to a septum instead of the females. At the highest release rate tested, 600 ng/h, many males were inactive or flew to the sides of the tunnel, which indicates sensory fatigue. This effect was more pronounced among males that were continuously exposed to the synthetic pheromone for the 4 days than among males kept in pheromone-free air between assays. About a quarter of the males died or became unable to fly after the 4 days, but there was no change in the proportions of the different responses of males, or in their response times, with increasing age, nor was there evidence that males were conditioned by their experience on previous days. The results led to the conclusion that time-averaged atmospheric concentrations of the synthetic pheromone as high as 20 ng/m3 are necessary to achieve effective disruption of the orientation of male spruce budworm moths to calling female moths.

New Formulation

A great deal of progress has been made over the last three decades in research on pheromone-mediated mating disruption technology for the oriental fruit moth,Grapholita molesta(Busck). Pheromones can interrupt normal orientation, and the most likely mechanism of pheromone disruption, competitive-attraction (false-plume following), invokes competition between point sources of pheromone formulation and females for males. This technology, performed by broadcasting pheromones into orchards to disrupt mate finding, has been successfully implemented in oriental fruit moth control. Reservoir-style dispensers made of polyethylene tubes, which release pheromone throughout the full growing season, are the current industry standard. Although reasonably effective, they require labor-intensive hand application. Recently, a new formulation, paraffin wax, which maximizes competition between point sources of synthetic pheromone and feral females for males, was shown to have high disruption performance. As this formulation is highly effective, inexpensive, and easy to produce, further study and development are advisable. Increased understanding of the principles of mating disruption will aid in the design of more effective dispensers. Continued research is needed to meet grower concerns with regard to risk, efficacy, and cost and to identify other semiochemicals that can be applied to this delivery system. Greater knowledge of the integration of different biological control methods is therefore essential.

Number Of Males

In field studies of pheromone-mediated mating disruption of lepidopteran pests, there are several ways to determine if mate location has been disrupted. One indirect method is to count the number of males caught in sticky traps baited with synthetic pheromone. A reduced catch in pheromone-treated plots relative to control plots shows that males were unable to find the source of synthetic pheromone and suggests that mating has been disrupted. More direct methods are: (1) to count the number of males attracted to sticky traps baited with virgin females; or (2) to assess the incidence of mating of (a) feral females collected in light-, bait- or other traps, (b) females caged with males in pheromone-treated areas, or (c) virgin females placed in the field and later retrieved. Females may be tethered with thread to non-sticky traps or partially dealated and placed on a “mating table” from which they cannot escape.

The leafroller Proeulia auraria (Clarke) (Lepidoptera: Tortricidae) is a native, polyphagous, and growing pest of several fruit crops in Chile; it also has quarantine importance to several markets, thus tools for management are needed. Using synthetic pheromone compounds, we conducted field trials to optimize the blend for monitoring, and to determine the activity period of rubber septa aged under field conditions. We concluded that septa loaded with 200 μg of E11-14:OAc + 60 μg E11-14:OH allowed for efficient trap captures for up to 10 weeks. Using this blend, we studied the phenology of adult males in vineyards, apple, and blueberry orchards, identifying two long flight cycles per season, lasting from September to May and suggesting 2–3 generations during the season. No or low adult activity was observed during January and between late May and late August. Furthermore, mating disruption (MD) field trials showed that application of 250 pheromone point sources using the dispenser wax matrix SPLAT (Specialized Pheromone and Lure Application Technology, 10.5% pheromone) with a total of 78 g/ha of the blend described above resulted in trap shutdown immediately after application, and mating disruption >99% in all orchards for at least 5 months. We concluded that MD is feasible for P. auraria, needing now the development of a commercial product and the strategy (and protocols) necessary to control this pest in conventional and organic orchards in Chile. As far as we know, this is the first report on MD development against a South American tortricid pest.

AbstractDisruption of mating for control of Oriental fruit moth [Grapholita molesta (Busck) (Lepidoptera: Tortricidae)] using Isomate M pheromone dispensers was tested from 1987 to 1990 in the Niagara Peninsula of Ontario. The effectiveness of pheromone was evaluated using virgin female-baited traps, synthetic pheromone-baited traps, and by inspecting samples of twigs and fruit for evidence of G. molesta damage. No males were caught in virgin female-baited traps placed in pheromone-treated plots. Synthetic pheromone-baited trap catches of male moths were reduced by 85–100%. Pheromone provided commercially acceptable control over two consecutive growing seasons at a commercial farm with a relatively low density G. molesta population. Pheromone did not provide commercially acceptable control at an experimental farm with a relatively high density G. molesta population. The incidence of capture of males in virgin female-baited traps, in synthetic pheromone-baited traps, and the incidence of damage to peach twigs by first- and second-generation G. molesta larvae could not be used to predict the incidence of damage to fruit at harvest. The results suggest that pheromone-mediated mating disruption may have potential as a method for controlling the Oriental fruit moth in orchards with relatively low density populations.

Trials were carried out in 1986 and 1987 with the mating disruption method for the control of oriental fruit moth (Cydia molesta Busck) in peaches of Northern Greece. One or two applications during April-September of the synthetic pheromone lsomate-M, at a rate of 1,000 units per ha, resulted in a 100% prevention of captures in pheromone traps in all trials, with fruit damage ranging from 0.1-2.0%. Damage in the conventionally sprayed treatments was 0.3-2.4% while infestation in the unsprayed plots reached 6-17%. The encouraging results, especially when taking into account the relatively small size of the orchards, opens opportunities for the integrated control of this peach insect pest under the condi­tions of Northern Greece.
