The identity, geographical distribution, and host range of codling moth is reviewed, and the evidence for sweet cherry being a host is critically analysed. A model is described which assesses the risk of codling moth being spread through international trade in sweet cherries, as exempli"ed by exports from, respectively, New Zealand and USA to Japan in winter and summer. The model is based on th...

A molecular protocol using a hemi-nested polymerase chain reaction (PCR) of the internal transcribed spacer region 2 (ITS2) is reported for the diagnosis of light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), in California. This protocol distinguishes the light brown apple moth from other moths in California based on size differences of PCR amplicons that are visua...

Codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae) is a major fruit feeding pest of apples. Understanding susceptibility differences of various apple cultivars to CM oviposition is an important step in developing resistant varieties as well as monitoring and management strategies for this pest in apple orchards planted with mixed-cultivars. In this context, oviposition preferenc...

We assessed the efficacy of cultivation as a potential management strategy for codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), and plum curculio, Conotrachelus nenuphar Herbst (Coleoptera: Curculionidae) in apple orchards. Cocooned codling moth pupae and thinning apples infested with plum curculio larvae were cultivated over in the field. Emergence, percent burial, damage to buried...

The heat-driven phenology model used for initiating codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), management in Washington state was examined to determine the need for using the capture of the first moth as a method of synchronizing the model and phenology of field populations (= biofix). We examined trap catch data taken at 1-2-d intervals from two research orchards; one data ...

The codling moth, Cydia pomonella L. (Lepidoptera, Tortricidae), is a major pest of apple, pear and walnut orchards worldwide. This pest is often controlled using the biologically friendly control method known as pheromone-based mating disruption. Mating disruption likely exerts selection on the sexual communication system of codling moth, as male and female moths will persist in their attempt ...

Unshelled walnuts were artificially infested with diapausing fifth ins tar codling moth, Cvdia nomonella (L.), larvae and fumigated with 56 g/m3 methyl bromide for 4 h at 15.6°C under a reduced pressure of 100 mm Hg. When 34,959 were treated, one larva survived, indicating a survival rate of 2.91 larvae per 100~000 treated. The upper 95% CL for this survival rate was 13.8 larvae per 100,000 tre...

Over two growing seasons, Isomate GBM-Plus tube-type dispensers releasing the major pheromone component of grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), were evaluated in vineyards (Vitis spp.) in Michigan, New York, and Pennsylvania. Dispensers were deployed in three different density-arrangement treatments: 124 dispensers per ha, 494 dispensers per ha, and a comb...
