Over the past several years my colleagues and I have been exploring ways of achieving moth mating disruption exceeding 95% efficacy even under high densities with limited insecticide inputs. The foundation for this work has been a series of studies examining the mechanisms underlying pheromone-based mating disruption in moth pests of pome fruit, stone fruit, walnuts, and citrus. Collectively, the results support competitive attraction or false-plume-following as an essential component of communicational disruption of moths in the family Tortricidae. Habituation of central nervous system (CNS) response appears to be an important supplementary mechanism for moths having oriented along plumes of high-dosage dispensers. Four main lines of evidence have led to these conclusions. Pheromone-based disruption of moths is density-dependent. Under high population densities, disruption increases as a function of increasing density of pheromone release sites. Effective mating disruption using high-dosage dispensers occurs in the field despite overall atmospheric concentrations not reaching levels high enough to desensitize moths by adaptation or habituation without close range (within cm) exposure to high dosage dispensers. Males are attracted to high-dosage dispensers in the field and such encounters desensitize the CNS but do not affect sensitivity of the peripheral nervous system. If competitive attraction followed by CNS habituation are the combined mechanisms achieving mating disruption, the following practical implications should be considered for developing high performance approaches and formulations: 1) distribution of dispensers should be uniform rather than clumped, 2) dispenser density should be high, and 3) release rate from synthetic dispensers should be within a physiologically attractive range but also sufficiently high to habituate male moth response following orientation.

An application of mating disruption by use of Ecodian CP dispensers (ISAGRO, Italy) in combination with the granulosis virus product Carpovirusine 2000 (Arysta LifeScience, France) against Codling moth (CM), Cydia pomonella, was tested near Plovdiv, Central South Bulgaria. In 2007, the method was applied in an orchard where in the previous year fruit damage reached 18.7% and the CM population was high, as indicated by 3.83 diapausing larvae per tree. Carpovirusine was applied 11 times in the trial plot in combination with Ecodian CP dispensers installed twice during the season. Before harvest, fruit damage in the trial plot amounted to 0.9% and the overwintering population in autumn 2007 was only 0.46 larvae per tree. At the same time in the reference orchard, where 15 insecticide treatments were applied during the season, fruit damage before harvest reached 12.3% and the hibernating population was 7.97 larvae per tree. So, it has been confirmed that combination of both methods might be an effective tool for control of codling moth in the orchards with high population density and resistance to conventional insecticides. This study is being continued.

This paper shows possibility of utilization ether derivatives of (8E,10Z)-tetradeca-8,10-dienal [2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan (2) and 2-((7E,9Z)-trideca-7,9-dienyl)-4-hydroxy-6-heptyl-5-hexyl-1,3-dioxan (3)] as potential lures for monitoring of horse-chestnut leafminer population. The both propheromones were synthesized at the Institute of Industrial Organic Chemistry (IPO) and then tested in 2006/07 on field trials at several different sites on terrain of Mazovian province. Within the scope of these investigations, acetal 2 was checked at different doses (10, 100, 500 μg) by the pheromone trapping technique, and aldoxane 3 was used both in pheromone trapping (at the dose 50 μg) and mating disruption technique. The good attractiveness properties were obtained for both tested compounds. However, the dose of 2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan had to be a 10 times higher than dose of aldoxane for the same good activity.
