Research and IPMPhenology Model Database
Peach Twig BorerScientific name: Anarsia lineatella Phenology models predict timing of events in an organism's development. For many organisms which cannot internally regulate their own temperature, development is dependent on temperatures to which they are exposed in the environment. Information in this database comes from published articles. It may be used in conjunction with field monitoring and a degree-day calculator.Note: Before using a model that was not field tested in your location, you should test the model for one or more seasons under your conditions to verify that it will work for you. Model 1 of 4Zalom, F. G., W. W. Barnett, R. E. Rice, and C. V. Weakley. 1992. Factors associated with flight patterns of the peach twig borer (Lepidoptera: Gelechiidae) observed using pheromone traps. J. Econ. Entomol. 85: 1904-1909. Location of study: California (10 years of field data) Developmental thresholds
Degree-day accumulations required for each stage of development Biofix: First male moth captured in pheromone traps.
Model 2 of 4Rice, R. E., F. G. Zalom, and J. F. Brunner. 1982. Monitoring peach twig borer development with degree-days. U.C. Div. Agr. Pub. #21302. SEE ALSO: Rice, R. E., F. G. Zalom, and J. F. Brunner. 1982. Using degree-days in a peach twig borer monitoring program. Almond Facts March/April 1982: 60-62.Location of study: California Developmental thresholds
Degree-day accumulations required for each stage of development Biofix: first male moth trapped; Set out traps: March 15 in southern part of Central Valley and April 10 in northern part of Central Valley
Model 3 of 4Peach twig borer. IN: Integrated Pest Management for Almonds. University of California Statewide IPM Project. Div. Agr. Sci. Publ. #3308. Location of study: Central Valley of California Developmental thresholds
Degree-day accumulations required for each stage of development Biofix: when moths are trapped on two consecutive sampling dates; Set out traps: March 20 in southern part of Central Valley and April 1 in northern part of Central Valley.
Model 4 of 4Brunner, J. F., and R. E. Rice. 1984. Peach twig borer, Anarsia lineatella Zeller (Lepidoptera: Gelechiidae), development in Washington and California. Environ. Entomol. 13: 607-610. Location of study: Washington and California (field and laboratory studies) Developmental thresholds
Degree-day accumulations required for each stage of development Biofix: First adult from overwinter generation. Start date: January 1
