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.

AbstractSex pheromone-mediated mating disruption using Isomate-C® pheromone dispensers was evaluated as a means of controlling the codling moth, Cydia pomonella, over three consecutive growing seasons in organically managed blocks of apples at two commercial apple orchards in Ontario. The objective of the study was to determine if mating disruption could be used to stabilize or reduce the amount of damage caused by indigenous codling moth populations. The emission rate of the pheromone dispensers was estimated using volumetric and gravimetric methods. Efficacy of the pheromone treatment was assessed by comparing pheromone-baited trap catches of adult male codling moths in pheromone- and insecticide-treated blocks of apples, and by estimating damage caused by first- and second-generation codling moths in pheromone- and insecticide-treated blocks as well as in small plots of apples where the codling moth was not controlled. The estimated average release rate of pheromone varied from 22.2 to 30.3 mg per ha per h. The seasonal total number of adult male moths trapped in the pheromone-treated blocks was from 3.8 to 25.3% of the number trapped in insecticide-treated blocks; during one season at one farm, no moths were trapped in a pheromone-treated block. Treatment with pheromone did not prevent an increase in codling moth damage. At one farm, damage increased ca. 5-fold during the 3-year study. At the other farm, damage increased ca. 4-fold during two consecutive growing seasons in one block and ca. 4-fold during three consecutive seasons in the other block. At both farms there was a marked increase in the amount of damage between the first and second generations of the pest. Possible reasons for the failure of the pheromone treatment to prevent increases in codling moth damage are discussed.

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.

Trials were carried out in 1987 and 1988 on the combined control of oriental fruit moth (OFM), Cydia molesta (Busck), and peach twig borer (PTB), Anarsia lineatella (Zell), in peach orchards in Northern Greece with Isomate-M pheromone dispensers (mating disruption technique) and insecticides against OFM and PTB, respectively. One application of the Isomate-M at a rate of 1,000 units per ha, and one application of the insect growth inhibitor (IGI) hexaflumuron 5 EC (200 ml f.p,/hl) or two sprays of fluvalinate 25 AF (60 ml f.p./hl) during June provided satisfactory control of OFM and PTB. Total damage per tree in the trials reached 1.0-3.6%, versus 1.4-3.0% in the conventionally sprayed orchards, while in unsprayed control blocks it was 14.4-23k. These encouraging results open possibilities for the combined control of these peach insects in Northern Greece.

Helicoverpa armigera is a polyphagous and globally distributed pest. In Italy, this species causes severe damage on processing tomato. We compared the efficacy of mating disruption with a standard integrated pest management strategy (IPM) in a two-year experiment carried out in Northern Italy. Mating disruption registered a very high suppression of male captures (>95%) in both growing seasons. Geostatistical analysis of trap catches was shown to be a useful tool to estimate the efficacy of the technique through representation of the spatial pattern of captures. Lower fruit damage was recorded in mating disruption than in the untreated control plots, with a variable efficacy depending on season and sampling date. Mating disruption showed a higher efficacy than standard IPM in controlling H. armigera infestation in the second season experiment. Mating disruption showed the potential to optimize the H. armigera control. Geostatistical maps were suitable to draw the pheromone drift out of the pheromone-treated area in order to evaluate the efficacy of the technique and to detect the weak points in a pheromone treated field. Mating disruption and standard IPM against H. armigera were demonstrated to be only partially effective in comparison with the untreated plots because both strategies were not able to fully avoid fruit damage.

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.

AbstractThe efficacy of mating disruption for controlling the grape berry moth, Endopiza viteana (Clemens) (Lepidoptera: Tortricidae), was evaluated from 1987 to 1989 in the Niagara peninsula, Ont. Mating disruption was tested in commercial vineyards with high-, moderate-, and low-density grape berry moth populations using the Biocontrol Ltd. tape-type and wire-type pheromone dispensers. Pheromone-baited trap catches were reduced by 92% or more in plots treated with pheromone. Treatment with pheromone significantly reduced damage (percentage infested clusters) compared with an untreated control in each of two tests, and provided control as good as or better than an insecticide control programme in two of four tests. Damage increased from 1.3- to 12.8-fold between successive generations in plots treated with pheromone, and was greater on the borders of some plots treated with pheromone or insecticide. It is concluded that mating disruption may have potential as a control method for use in the integrated management of E. viteana.
