applying a precise forecasting method is necessary to achieve acceptable results in ipm programs. performances of the wing and delta pheromone traps for forecasting the codling moth phenology were compared with physiological time data based on degree-hours. six pheromone traps (three wing and three delta style) were applied for the monitoring of the codling moth population. traps were placed in...

A 4-yr research and implementation project in Michigan apple production showed that deploying pheromone-mediated mating disruption for codling moth, Cydia pomonella L., in an areawide (AW-CMMD) program where mating disruption is established on all apple-producing acreage on individual and adjacent farms, significantly improves control of codling moth. The areawide project was compared with mati...

Tests were conducted to determine the potential for high hydrostatic pressure (HPP) to control codling moth, Cydia pomonella (L.), and western cherry fruit fly, Rhagoletis indifferens Curran. Apples (Malus spp.) with codling moth larvae or eggs were treated at 24 and 72 h, respectively, after infestation at a series of pressures between 14,000 and 26,000 pounds per inch2 (psi). Survivorship was...

Codling moth is a major pest of apples and pears worldwide. Increasing knowledge of how this insect responds to environmental stress will improve field and postharvest control measures used against it. The small heat shock proteins (sHsps) play amajor role in cellular responses to environmental stressors. A degenerate oligonucleotide primer, designed against the conserved α-crystallin domain, w...

High dose aerosol emitters of pheromone, “puffers”, have been used successfully for over 15 years for control of codling moth in pears, and more recently have emerged as the leading mating disruption strategy in walnuts. While their efficacy is well documented, the mechanisms by which they operate are still not properly understood. Understanding how this type of dispenser works may provide oppo...

Apples destined for export to Japan and South Korea are currently disinfested for codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), using methyl bromide fumigation. Restrictions and limitations imposed on the uses of methyl bromide have increased interest in developing alternative non-chemical quarantine treatments. It is imperative that the treatment is effective against codling mot...

Development of alternative pheromone dispensers continue to show promise for disruption of long-range communication between male and female codling moths. Hollow fibers containing the codling moth pheromone that can be dispersed at 30,000-40,000 units per acre can currently be distributed by specialized application equipment affixed to either helicopters or fixed wing aircraft, whereas efforts ...

Codling moth is a notorious fruit-boring pest that has extended its original distribution from the natural apple forests of Central Asia to cover all apple growing regions of the world. Having been discovered in California as early as 1872, codling moth has continued to be the dominant pest of apple, pear and walnut production causing extensive damage in the absence of insecticide treatment. In...

Field tests were conducted in 1983 at Hanford, CA, to further investigate the use of the codling moth granulosis virus (GV) as a control agent. Timing of application and number of applications were investigated. Sprays were commenced at 0.1 and 10% predicted hatch for the GV as well as Zolone. In the small plots, first brood damage was assessed by counting the number of fallen codling moth infe...

Several application parameters of microencapsulated (MEC) sex pheromone formulations were manipulated to determine their impact on efficacy of disruption for codling moth, Cydia pomonella (L.); oriental fruit moth, Grapholita molesta (Busck); obliquebanded leafroller, Choristoneura rosaceana (Harris); and redbanded leafroller, Argyrotaenia velutinana (Walker). Depending on the experiment, the f...
