Dose–Response of Codling Moth (Lepidoptera: Tortricidae) to Ethyl (E,Z)-2,4-Decadienoate in Apple Orchards Treated with Sex Pheromone Dispensers

In 3 successive years (1990-1992) polyethylene tube dispensers, each containing 50.5 mg synthetic sex pheromone of the apple clearwing moth, Synanthedon (Aegeria) myopaeformis Borkh., were placed at a density of 680 per ha, once a year, in two adjacent commercial apple orchards each I ha in size. The degree of confusion reached almost 100% by releasing about 6 mg/ha/h, whereas the number of mated females decreased by 72.86%, compared with the untreated orchard. In 1993, after 3 years of experiments, a reduction of up to 91% of empty pupal skins per tree was attained. The encouraging results, especially when taking into account the relatively small size of the orchards, opens opportunities for the integrated control of this apple insect pest under the conditions of Northern Greece.

AbstractWe evaluated the effectiveness of 2-phenylethanol (PET) in combination with acetic acid (AA) as a binary lure for monitoring male and female obliquebanded leafroller, Choristoneura rosaceana (Harris). Studies were conducted in apple, Malus domestica Borkhausen, orchards treated with or without sex pheromone dispensers for mating disruption (MD). Open polypropylene vials, closed membrane cups, and rubber septa loaded with AA and/or PET in varying amounts were first evaluated in a series of trapping experiments. Membrane cups loaded with 800 mg of PET were as effective as 10-mg septa, but longer lasting, and were comparable to the open vials. A membrane cup AA lure was effective in tests, but further work is needed to increase its release rate and extend its activity. Catches of codling moth, Cydia pomonella (L.), and C. rosaceana were unaffected by combining PET with (E,E)-8,10-dodecadien-1-ol, the sex pheromone of codling moth, pear ester, (E,Z)-2,4-ethyl-decadienoate, and AA lures. Adding (E)-4,8-dimethyl-1,3,7-nonatriene to this blend to enhance codling moth catch, significantly reduced catches of C. rosaceana. PET+AA was a more attractive binary lure than AA plus phenylacetonitrile (PAN) for C. rosaceana. The addition of PET or PAN to traps already baited with the sex pheromone of C. rosaceana significantly reduced male catches. Traps baited with PET+AA placed in blocks not treated with MD caught significantly fewer C. rosaceana than traps baited with sex pheromone. In comparison, sex pheromone-baited traps in MD blocks caught ≤ 1 male moth per season which was significantly lower than total moth (> 10) or female moth (≥ 3) catch in these blocks with PET+AA. A high proportion (> 70%) of trapped females were mated in both untreated and MD-treated orchards. Further refinement of this binary, bisexual lure using membrane cup technology may allow the establishment of action thresholds and improve management timings for C. rosaceana.

Monitoring Activity

AbstractIn Ontario apple orchards, the amount of synthetic codling moth (Cydia pomonella (L., 1758)) sex pheromone, E,E-8,10-dodecadien-1-ol (0.01–10.0 mg) used to bait traps significantly affected the mean total numbers of moths captured, whereas similar mean total numbers of moths were captured in traps baited with different amounts of pear-derived kairomone, ethyl (2E,4Z)-2,4-decadienoate (0.01–10.0 mg). The attractiveness of kairomone-baited traps was not increased by using greater amounts (100 and 1000 mg) of this compound. The attractiveness of the pheromone was not enhanced by the addition of kairomone. Similar patterns of adult male seasonal activity were observed when using pheromone-baited traps and kairomone-baited traps. The potential usefulness of kairomone-baited traps in the integrated management of C. pomonella in Ontario apple orchards is discussed.

Laspeyresia Pomonella

AbstractCodling moth populations in six orchards in the Okanagan and Similkameen valleys of British Columbia were monitored for 2 seasons with traps baited with trans-8, trans-10, dodecadien-1-ol, the sex pheromone of the codling moth, Laspeyresia pomonella (L.). Sprays were applied if traps within the orchard captured two or more moths per trap per week during 2 consecutive weeks. Traps installed in neighboring orchards minimized male moth influx. A 43.1% reduction in the number of required cover sprays for codling moth control was obtained over a 2-year period compared with a standard three spray program. Fruit injured by codling moth in monitored orchards varied, but was less than 1% in all but one orchard.
