Seasonal flight patterns of codling moth (Lepidoptera: Tortricidae) monitored with pear ester and codlemone-baited traps in sex pheromone-treated apple orchards
Environmental Entomology 34 (5), 1028-1035
Abstract: Traps baited with ethyl (E, Z)-2, 4-decadienoate (pear ester) or (E, E)-8,10-dodecadienol (codlemone) were used to monitor codling moth, Cydia pomonella L., (Lepidoptera: Tortricidae) in 102 apple, Malus domestica Borkhausen, orchards. All orchards were treated with 500-1,000 Isomate-C PLUS dispensers/ha during 2000-2002. Traps baited with pear ester caught their first moth significantly later on average than the paired codlemone-baited traps, but timing of peak moth catch during each moth flight coincided with both types of lures. The timing of first male moth capture in pear ester-baited traps was significantly earlier than the first female moth; and the percentage of male moths in the total numbers of moths captured ranged from 55 to 60% over the three seasons. The percentage of female moths caught by pear ester-baited traps that were mated exceeded 80% each year. Pear ester-baited traps caught similar numbers of moths as codlemone-baited traps during 2000. However, the density of sex pheromone dispensers per hectare was increased in most orchards in 2001-2002; and pear ester outperformed codlemone-baited traps in both years.
