Research and IPMPhenology Model Database
Potato TuberwormScientific name: Phthorimaea operculella 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 2Cardona C., and E. R. Oatman. 1975. Biology and physical ecology of Apanteles subandinus Blanchard (Hymenoptera: Braconidae) with notes on temperature responses of Apanteles scutellaris (Muesebeck) and its host, the potato tuberworm. Hilgardia 43: 1-51. Location of study: Riverside, California (laboratory studies) Developmental threshold
Method of calculation: not specified (UC IPM recommends Single Sine) Degree-day accumulations required for each stage of development
