Improvement of the sterile insect technique for codling moth Cydia pomonella (Linnaeus) (Lepidoptera Tortricidae) to facilitate expansion of field application
نویسندگان
چکیده
The codling moth Cydia pomonella (Linnaeus) (Lepidoptera Tortricidae) is a key pest of pome fruit (apple, pear and quince) and walnut orchards in most temperate regions of the world (Barnes 1991; CABI 1995). The moth has followed the spread of the apple tree Malus pumila Miller around the world, and

Costs and benefits of thermal acclimation for codling moth, Cydia pomonella (Lepidoptera: Tortricidae): implications for pest control and the sterile insect release programme
Sterile insect release (SIR) is used to suppress insect pest populations in agro-ecosystems, but its success hinges on the performance of the released insects and prevailing environmental conditions. For example, low temperatures dramatically reduce SIR efficacy in cooler conditions. Here, we report on the costs and benefits of thermal acclimation for laboratory and field responses of codling m...
متن کاملPEST MANAGEMENT AND SAMPLING Season-Long Releases of Partially Sterile Males for Control of Codling Moth (Lepidoptera: Tortricidae) in Washington Apples
Season-long Þeld studies were conducted in Washington apple orchards that compared the following: (1) twice per week releases of partially sterile codling moths, Cydia pomonella (L.), treated with either 100 or 250 Gy, and (2) combinations of mating disruption plus the release of partially sterile (100 Gy) codling moths, to control wild codling moth populations. No signiÞcant differences in the...
متن کاملA cumulated lethal time model to evaluate efficacy of heat treatments for codling moth Cydia pomonella (L.) (Lepidoptera: Tortricidae) in cherries
Developing heat treatment methods to control insect pests in harvested commodities has traditionally relied on empirical trial-and-error approaches. There is a need for an effective means to systematically develop and assess heat treatments to save time and expense. In this study, we developed a cumulated lethal time model based on the efficacy of different hot water treatments for killing codl...
متن کاملImpact of Cultivation and Subsequent Burial on Cydia pomonella (Lepidoptera: Tortricidae) and Conotrachelus nenuphar (Coleoptera: Curculionidae)
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...
متن کاملLaboratory Infestation of Sweet Cherry by Codling Moth (Lepidoptera: Tortricidae): Factors Affecting Survival1
Sweet cherries, Prunus avium L., from the United States must be fumigated to control codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), before exporting them to Japan. However, the status of sweet cherry as a true host for codling moth has been debated because of the limited survival of the pest. Previously, laboratory methods have been developed to rear the codling moth on sweet ch...
