We compared the field competitiveness of sterile codling moth, Cydia pomonella (L.), males mass-reared through diapause or standard production protocols and treated with either 150 or 250 Gy of gamma radiation. Evaluations were performed during spring and summer 2003 by using field release-recapture tests. Released males were recaptured using traps baited with synthetic pheromone or with virgin females. In addition, mating tables baited with virgin females were used in the summer to assess the… Expand
Diapause improves springtime mating competitiveness of male codling moth mass‐reared for a sterile insect programme
TLDR
The objective of this field study was to assess the mating competitiveness and recapture of sterilized male codling moths that have been mass-reared through a diapause larval state in comparison to wild males that developed on apples but also emerged from larval diAPause in spring. Expand
Cold treatment enhances low‐temperature flight performance in false codling moth, Thaumatotibia leucotreta (Lepidoptera: Tortricidae)
TLDR
A temperature‐dependent interaction between acute cold exposure and flight performance in adult T. leucotreta is suggested, which may be used to enhance the efficacy of the sterile insect technique under cooler environmental conditions. Expand
Is lack of mating competitiveness in spring linked to mating asynchrony between wild and mass‐reared codling moths from an operational sterile insect programme?
TLDR
It is hypothesize that differences between wild and mass‐reared males in daily timing or speed of responses to natural or synthetic pheromone sources under montane weather patterns typical of spring in British Columbia may partially explain poor activity of sterile males, and low sterile : wild overflooding ratios during spring when measured using phersomone traps by the sterile insect release programme in British Canada.

Developing Field Cage Tests to Measure Mating Competitiveness of Sterile Light Brown Apple Moths (Lepidoptera: Tortricidae) in Western Australia
TLDR
Results indicated that sterile-male-only releases have the potential to increase mating competitiveness of the released irradiated moths, but this conclusion requires additional experiments for confirmation. Expand

Influence of Holding Temperature and Irradiation on Field Performance of Mass-Reared Thaumatotibia leucotreta (Lepidoptera: Tortricidae)
TLDR
Trials to examine the effect of irradiation with 150 Gy of gamma rays and cold temperature storage on the performance of T. leucotreta moths released in citrus orchards found moths that were rapidly chilled were less likely to be captured in pheromone traps and more likely to disperse as great distances following release in citrusOrchards.

A flight cylinder bioassay as a simple, effective quality control test for Cydia pomonella
TLDR
The flight cylinder bioassay was successful in detecting differences in codling moth quality induced by various treatments that had been identified previously by more complex laboratory bioassays and field trials. Expand
Development of Sterile Insect Technique for Control of the European Grapevine Moth, Lobesia botrana, in Urban Areas of Chile
TLDR
The progress made to develop the SIT response capacity with a production of 75,000 sterile moths per week is reported, as well as the results from a season-long SIT release program in a section of a small city in a grape and fruit production region in central Chile. Expand
Evaluating Flight Performance of Mass-Reared and Irradiated Navel Orangeworm (Lepidoptera: Pyralidae) for Sterile Insect Technique
TLDR
Findings from this study suggest that mass-rearing conditions reduce A. transitella flight capacity, while irradiation interacts with moths in a sex-specific manner. Expand

Inherited sterility in codling moth (Lepidoptera : Tortricidae) : Effect of substerilizing doses of radiation on field competitiveness
TLDR
In mating table experiments, successful matings decreased as the dose of radiation increased, and Untreated males were the most competitive among released codling moths. Expand
Inherited sterility in codling moth (Lepidoptera: Tortricidae): effect of substerilizing doses of radiation on insect fecundity, fertility, and control.
TLDR
Male and female codling moths, Cydia pomonella, were treated with increasing doses of gamma radiation, and the moths were either inbred or outcrossed with fertile counterparts, shifting the F1 sex ratio shifted in favor of male progeny. Expand

Mass-rearing and storing codling moth larvae in diapause: a novel approach to increase production for sterile insect release
TLDR
A method that induces diapause, originally developed for individually reared codling moth (CM), Cydia pomonella (L.) was tested on the open tray, sawdust-based diet system used in Canada for mass-rearing and the benefits and economics are discussed. Expand
Passive Trap for Monitoring Codling Moth (Lepidoptera: Tortricidae) Flight Activity
TLDR
Field experiments demonstrated that the passive pane-trap method is as efficient for catching moths as molasses-baited traps but that it is less efficient than pheromone-baiting and blacklight traps placed in an orchard at equal densities, however, total capture of moths in plots treated with pane traps increased with trap density.
