CONTROL OF CODLING MOTH AND ORIENTAL FRUIT MOTH, 2010

AbstractExperiments and observations on Oriental fruit moths in cages and in a peach orchard showed that both males and females may mate more than once. The maximum recorded number of matings was 7 for males and 5 for females. Mating usually occurred in the late afternoon and early evening during the daily flight and egg-laying period. Males seldom mated oftener than once in 24 hours and they transferred only one spermatophore to the female per mating. In cages, males mated approximately 1.4 times each when confined with equal numbers of females. Of the females taken in bait traps in a peach orchard, an average of 2.9% had not mated, 78.8% had mated once, 14.6% twice, and 3.7% more than twice. The mating behaviour of the Oriental fruit moth was shown to be similar to that of the codling moth.

Trap Catches

AbstractPheromone traps were deployed in Borsod-Abaúj-Zemplén County (Hungary) between 1982 and 1988, in 1990 and also between 1993 and 2013. These traps attracted 8 Microlepidoptera species:Phyllonorycter blancardella, P. corylifoliella,Anarsia lineatella,Eupoecilia ambiguella,Lobesia botrana,Grapholita funebrana,G. molestaandCydia pomonella. We examined the trapping data of these species in the context of lunar phases and polarized moonlight. Catches of the European Vine Moth (Lobesia botrana) and the Codling Moth (Cydia pomonella) were higher in the First Quarter, whereas catches of Peach Twig Borer (Anarsia lineatella), Vine Moth (Eupoecilia ambiguella), Plum Fruit Moth (Grapholita funebrana) and Oriental Fruit Moth (Grapholita molesta) were larger in the Last Quarter. Catches of the other two species, the Spotted Tentiform Leafminer (Phyllonorycter blancardella) and Hawthorn Red Midget Moth (P. corylifoliella), were higher in both the First and Last Quarters. When using pheromone traps, insects do not fly to a light source, so moonlight does not modify either the catching distance or flight activity. However, at high levels of polarized moonlight, pheromone trap catches will increase, as in the case of light-trap catches. The results are comprehensible when one considers that the target species can fly both during the daytime and also at night.

Cultivar Susceptibility

As part of a regional NE-183 project (Multidisciplinary Evaluation of New Apple Cultivars), 23 apple (Malus ×domestica Borkh.) cultivars were evaluated for arthropod pest susceptibility. Incidence or injury data were collected from six foliage and eight fruit pests under field conditions over a four year period (2000–03). Cultivars were ranked based on susceptibility (least to most) to each pest, and rankings were summed for members of the foliage and fruit pest group to develop a susceptibility rating for foliage, fruit and all pests combined. Cultivars with lowest susceptibility to foliage pests included `GoldRush' and `Pioneer Mac', whereas `Yataka' and `Cameo' were most susceptible. For fruit pests, susceptibility was lowest for `Pristine' and `Sunrise', and highest for `Cameo', `Fuji Red Sport #2', and `Gala Supreme'. When both foliage and fruit pests were combined, susceptibility was lowest for `Sunrise' and `Pioneer Mac', and highest for `Cameo'. Some increasingly popular cultivars had high levels of injury from a few pests, including plum curculio and apple maggot on `Ginger Gold', codling moth and oriental fruit moth on `Cameo', and japanese beetle, plum curculio and apple maggot on `Honeycrisp'. A positive and significant correlation was found between day of harvest and percent fruit injury from codling moth/oriental fruit moth and tufted apple bud moth/redbanded leafroller, with later maturing cultivars experiencing higher injury levels presumably due to more exposure to later generations of these pests. Differences among cultivars in pest incidence and injury can be used by growers to improve pest management through cultivar selection, or by making modifications in control programs based on cultivar susceptibility.
