In Bulgarian fruit growing agriculture mainly chemical plant protection is applied. Applications with organophosphates and pyrethroids are carried out to control the economically most important peach pest - the oriental fruit moth (Grapholita molesta Busck.). Annually during the vegetation season 7-8 insecticide treatments are applied. This leads to contamination of fruit products and the environment, which is a prerequisite for seeking other approaches. Regarding to fruit moth, sex pheromones are one of the most widely used environmental control methods, but they are most commonly used in apples. Their introduction in the monitoring of the main peach pest can lead to a reduction of chemical treatments and production with less pesticide residues. A promising direction is the use of pheromones to control the pests through sexual disorientation of males. The trial of mating disruption in the present study were carried out with ISOMATE® OFM TT dispensers in 0.9 ha peach orchard in 2020 and 2021. Pheromone traps type "Delta" of the Hungarian company CSALOMON® were used. The ISOMATE OFM TT dispensers, installed before the first flight of OFM at the rate of 250 units per ha, efficiently reduced fruit damages - down to 0.1-0.2% at harvest. In the reference orchard with 6 insecticide treatment against OFM, the damages reached 3.0-3.6%. The results indicate that mating disruption for control of Grapholita molesta Busck. can be used in production of quality and healthy peach fruits.

Monitoring oriental fruit moth Grapholita molesta Busck (Lepidoptera: Tortricidae), populations based on counts in sex pheromone-baited traps within sex pheromone-treated orchards for mating disruption (MD) is challenging since male orientation to traps is disrupted. In this study, we evaluated a new commercial pheromone–kairomone combination lure for G. molesta (Pherocon® OFM Combo™ Dual™), which combines the G. molesta and Cydia pomonella L. sex pheromones with a blend of acetic acid and terpinyl acetate. Trap comparisons were performed in 33 trials in peach and nectarine orchards under MD (24) or non-MD (9) during the 2018–2019 period in Italy. Male and total moth captures in traps baited with the combination lure were significantly greater than in traps with G. molesta pheromone in both years and across both pheromone treatments. The proportion of females in the total moth captures using the combination lure averaged ca. 7% across all trials. The by-catch of non-targets, i.e., Apis mellifera L., was low in traps baited either with the combination and the sex pheromone lure, while trap color (white) affected the capture of beneficials but not of the target pest. Our study proves that this combination lure can improve the monitoring and management for G. molesta in stone fruits. New studies are needed to define action thresholds to trigger supplemental control methods to MD. Secondly, female-based monitoring lures should be further developed to improve management strategies.

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.

Oriental fruit moth (OFM) is an important pest of summerfruit grown for both fresh market and processing in Hawkes Bay New Zealand Mating disruption was applied over three consecutive years on the same three cv Golden Queen peach orchards At each orchard plots of 0535 ha were treated with pheromone dispensers either alone or supplemented with insecticides In year one OFM populations were high and mating disruption or 12 insecticide applications did not provide sufficient control with up to 3 damage at harvest The following year all trial areas received pheromone dispensers plus one or two insecticide applications and fruit damage was at acceptable level of less than 1 In year three blocks with mating disruption alone averaged 02 OFM infestation compared with 09 where no OFM control was used OFM mating disruption is now increasingly being adopted by growers but the cost relative to insecticides is a barrier

The sale of pheromone traps lures and mating disruption products for horticultural insect pest species has grown steadily since the late 1980s with expanding sales to New Zealand growers from Plant Food Research (PFR) and its predecessors New biosecurity incursions led to pheromone identifications for delimitation and pest management of other species Mating disruption products were developed to target leafrollers currant clearwing codling moth and oriental fruit moth In 201011 the activity involved with production of > 30 pheromone products was sold as a business unit by PFR to a New Zealand company In addition the first legislative group standard for plant protection products was drawn up to enable future development of straightchained lepidopteran sex pheromones under New Zealands Environmental Protection Authority The availability of pheromone products to assist with decision support and pest management is now subject to market forces
