In 1980-1983 small-scale tests were conducted and background information was obtalned to determine the feasibility of developing a quarantine treatment with methyl bromide (MB) for the codling moth (Cydia pomonella La) infesting in-shall walnuts. Some of the studies conducted at this time included basic dose mortality responses of diapausing and nondiapausing larvae, residue determinations and ...
Studies were conducted with codling moth, Cydia pomonella L., to evaluate the mating status of male and female moths in apple, Malus domestica (Borkhausen), orchards treated with and without sex pheromone dispensers. Laboratory studies first examined the effect of multiple mating of male and female moths on female fecundity and egg fertility. Females that had mated three times had a significant...
A radio frequency (RF) treatment, with a pulse mode to increase heating uniformity, was examined as a potential quarantine treatment against fifth instars of the codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), in apples, Malus sylvestris L. var. domestica (Borkh.) Mansf., intended for export to Japan. Apples were exposed in water baths to 27.12MHz RF energy at 12 kW with a pulse mo...
Olfaction plays a dominant role in the mate-finding and host selection behaviours of the codling moth (Cydia pomonella), an important pest of apple, pear and walnut orchards worldwide. Antennal transcriptome analysis revealed a number of abundantly expressed genes related to the moth olfactory system, including those encoding the olfactory receptors (ORs) CpomOR1, CpomOR3 and CpomOR6a, which be...
Previous studies supported by the Walnut Board had shown that survival of codling moth (CM) larvae is proportional to their age at the time of harvest and that overall survival is poor compared to siblings reared on artificial diets. In 1986 considerably more data were collected on the infestation levels of codling moth in different varieties of walnuts. In addition, the population structure at...
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 ...
