codling moth

Lepidopteran insects use sex pheromones to communicate for mating. Olfactory communication and mate-finding can be prevented by permeating the atmosphere with synthetic pheromone. Pheromone-mediated mating disruption has become a commercially viable pest management technique and is used to control the codling moth, Cydia pomonella, a key insect pest of apple, on 160,000 ha worldwide. The codling moth sex pheromone, codlemone, is species specific and nontoxic. Orchard treatments with up to 100 grams of synthetic codlemone per hectare effectively control codling moth populations over the entire growing season. Practical implementation of the mating disruption technique has been realized at an opportune time, as codling moth has become resistant to many insecticides. We review codling moth chemical ecology and factors underlying the behavioral mechanisms and practical implementation of mating disruption. Area-wide programs are the result of collaborative efforts between academic resear...

A simple method for laboratory rearing of codling moth on artificial diet is explained and tested. The present study revealed important aspects of the insect rearing. Rearing quality raised up to %95 under high sanitary rearing conditions. Optimal number of larvae in each container (enough amount of diet per larva) and suitable uncrowded moths in rearing cage were determined to give the best fertility. Egg hatch rate averaged %91.4 ± 5. Larvae-pupae rearing quality ranged between %60-90 . Moth emergence lasted 30.37 days in average when neonate larvae enter the medium at the same time. Longevity of the resulted moths was 16.8 days in average with a fecundity of 177.8 eggs per female.

The non-insecticidal control strategies currently being implemented in South African orchards for the control of codling moth, Cydia pomonella (L.) may be hampered by wooden fruit bins being infested with diapausing codling moth larvae, acting as a potential source of re-infestation. Key factors contributing to the success or failure of an entomopathogenic nematode application were investigated using the SF 41

This paper reports on the second part of a scaling-up study investigating the technical feasibility of using radio frequency (RF) energy in commercial postharvest insect control in in-shell walnuts as an alternative to chemical fumigation. A large-scale treatment for conveyorized walnuts was designed based on a 25kW, 27MHz RF system to achieve an average walnut surface temperature of 60°C, and

Genetic transformation of the codling moth, Cydia pomonella, was accomplished through embryo microinjection with a plasmid-based piggyBac vector containing the enhanced green fluorescent protein (EGFP) gene. Sequencing of the flanking regions around the inserted construct resulted in identification of insect genomic sequences, not plasmid sequences, thus providing evidence that the piggyBac EGFP cassette had integrated into the codling moth genome.
