Stage-specific development of Sparganothis sulfureana (Lepidoptera: Tortricidae) [abstract]. North American Cranberry Research and Extension Workers Annual Meeting. p. 1.Interpretive Summary:
                                Technical Abstract: Sparganothis fruitworm (SFW) is one of the most serious pests of cranberries. SFW larval growth rates were measured over a wide range of controlled temperatures (44-101°F). Growth rates were then plotted against temperature and a model was fit to the dynamic. From this model, we were able to determine the lower (48°F) and upper (85°F) development thresholds of SFW larvae. The thresholds were used to generate degree-day (DD) accumulations that were linked to developmental events, such as flight initiation and length, adult lifespan, pre-ovipositional period, ovipositional period, and egg gestation period. These DD accumulations represent key developmental benchmarks, helping to optimize pest management in the cranberry system.
