Interpretive Summary:

Technical Abstract: Sparganothis sulfureana, also known as the Sparganothis fruitworm, is one of the most significant, ubiquitous pests of cranberry in North America. To better predict its development in the field, basic information on its temperature-mediated growth is needed. Under a range of temperatures, larvae were reared on cranberry uprights and weight gain was measured. Growth rates were then plotted against temperature and modeled to determine the best statistical fit. Based on this model, maximum and minimum thresholds were isolated. These thresholds are then used to calculate degree-day accumulations, which are associated with biological attributes of the population to effectively characterize the developmental status in the field.
