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…

Diapause improves springtime mating competitiveness of male codling moth mass‐reared for a sterile insect programme

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.

Is lack of mating competitiveness in spring linked to mating asynchrony between wild and mass‐reared codling moths from an operational sterile insect programme?

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

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.

Influence of Holding Temperature and Irradiation on Field Performance of Mass-Reared Thaumatotibia leucotreta (Lepidoptera: Tortricidae)

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

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.

Sterility of Cydia pomonella by X ray irradiation as an alternative to gamma radiation for the sterile insect technique

Abstract The codling moth Cydia pomonella is a major pest of global significance impacting pome fruits and walnuts. It threatens the apple industry in the Loess Plateau and Bohai Bay in China.

Evaluating Flight Performance of Mass-Reared and Irradiated Navel Orangeworm (Lepidoptera: Pyralidae) for Sterile Insect Technique

Findings from this study suggest that mass-rearing conditions reduce A. transitella flight capacity, while irradiation interacts with moths in a sex-specific manner.

Inherited sterility in codling moth (Lepidoptera: Tortricidae): effect of substerilizing doses of radiation on insect fecundity, fertility, and control.

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.

Temperature-mediated programming provides a potential means of synchronizing activity rhythms of sterile males with those of wild males in target populations; however, on any given day, males from lower pupal temperature regimes were captured consistently earlier than males from warmer regimes.
