AbstractThe use of the timing of moth catch in traps to predict the start of egg hatch by first-generation codling moth, Cydia pomonella (L.), in apple, Malus domestica Borkh. (Rosaceae), was evaluated with ethyl (E,Z)-2,4-decadienoate (pear ester) and (E,E)-8,10-dodecadien-1-ol (codlemone) lures. Two sets of paired traps baited with either lure were placed in each of seven orchards and checked daily during the spring flight in 2000 and 2001. Rearing of field-collected eggs and sampling of fruit for injury were used to estimate the date of first egg hatch. Moth catch in traps baited with codlemone and pear ester occurred approximately 144 and 105 degree-days prior to the start of egg hatch, respectively. The effectiveness of using the timing of sustained moth catch in traps baited with these lures as a biological reference point (Biofix) to predict the start of egg hatch when traps were checked every 3–4 d was evaluated in 11 orchards from 2000 to 2002. The calendar date for the start of sustained moth catch in traps baited with either lure varied widely among orchards and years. Significant differences in mean cumulative degree-days from first sustained moth catch until egg hatch were found among male moth catch in codlemone-baited traps and total and female moth catch in pear ester-baited traps. Adjusting the Biofix based on daily temperature thresholds significantly changed the cumulative degree-days required until egg hatch only for female moth catch. No significant differences were found in the accuracy of predicting the date of egg hatch using either the codlemone or pear ester lure or by adjusting the Biofix date using daily temperature thresholds. The cumulative degree-day totals required from Biofix until egg hatch had the lowest variability when the Biofix was (i) based on the sustained catch of female moths in a pear ester-baited trap and (ii) adjusted with a temperature threshold for moth activity.

AbstractThe efficacy of diflubenzuron against the codling moth, Laspeyresia pomonella L., was compared with that of azinphos-methyl in two orchards. Two cover sprays were applied to coincide with peak codling moth activity which was monitored daily with pheromone-baited traps. In the Golden Delicious and mixed cultivar orchards, 187 ppm (mg active ingredient/1.) diflubenzuron provided control comparable to that of 187 ppm azinphos-methyl. In the 47 ppm diflubenzuron treatment, more fruit damage occurred particularly in the mixed cultivar orchard. In this orchard, the addition of Tween 20 to the spray mixture reduced fruit damage markedly.Diflubenzuron appeared non-toxic to the phytoseiid Typhlodromus occidentalis Nesbitt and stigmaeid Zetzellia mali Ewing. In addition, cover sprays did not increase populations of European red mite, Panonychus ulmi (Koch) or rust mites, Aculus spp.The efficacy of diflubenzuron against the codling moth and its compatability with integrated mite control suggest that the compound is a promising agent for pest management programs in apple orchards.

AbstractTraps baited with either ethyl (E,Z)-2,4-decadienoate (pear ester) or (E,E)- 8,10- dodecadien-1-ol (codlemone) (Pherocon® CM-DA™ and Megalure CM™ lures, respectively) were used to develop action thresholds for codling moth (Cydia pomonella (L.)) in apple (Malus domestica Borkh.; Rosaceae) orchards treated with sex pheromones for control of this pest. Studies were conducted in 102 orchards treated with 500–1000 ISOMATE®-C PLUS dispensers per hectare during 2000–2002. Pairs of traps were placed within two 1.0-ha plots within each orchard. Fruit injury was assessed at mid-season and prior to harvest in each plot. The numbers of female and total moths caught in pear ester-baited traps and male moths caught in codlemone-baited traps were used to develop action thresholds. Thresholds were based on the minimum cumulative number of moths per trap in ≥95% of traps in unsprayed plots with no fruit injury. Specific thresholds were established for the first insecticide spray targeting the start of egg hatch and for the first and second moth flights. The proportion of plots with mid-season fruit injury that had cumulative moth catches below the action threshold at first spray and at second moth flight was determined using the established action threshold and thresholds reduced incrementally to ≥1 moth per trap. Moth catches below the threshold at first spray were less common in plots with high levels of fruit injury (>0.3%) than in plots with low levels of fruit injury and more common with codlemone-baited traps than with pear ester-baited traps. An action threshold of ≥1 moth in a pear ester-baited trap at first spray eliminated the error in predicting fruit injury in plots at mid-season. Conversely, a high proportion of traps baited with either lure failed to predict low levels of fruit injury at harvest in unsprayed plots regardless of the cumulative moth threshold used during the second moth flight.

AbstractTraps baited with the codling moth, Laspeyresia pomonella (L.), sex pheromone, trans-8, trans- 10-dodecadien-1-ol, were evaluated for their suitability in a pest management program in an area of high host abandonment. Modifications in trap design, trap condition, or pheromone cap type resulted in variation in male moth catch. In commercial orchards the necessity of both interior and perimeter traps is indicated. Reduction in pesticide sprays was obtained in two of the four orchards monitored, but utilization of traps in a pest management program is hampered by several factors including orchard design, grower attitude, and considerations of cultural practices.

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.
