Symposium: New Technologies for the Taxonomic Identification of Arthropods: Predicting the Phenology of Heliothis Virescens (Lepidoptera: Noctuidae) on Tobacco using Accumulated Degree-Days
AbstractDegree-day (@*D) estimates were calculated between Heliothis virescens (F.) population peaks of adult males and between larval infestation peaks on tobacco in Florida. The mean @*D between the first and second and between the second and third adult peaks for 3 years was 512 and 583, respectively. The mean @*D between the first and second larval peaks was 550. Similarly, there was a mean of 554 @*D between the first and second larval damage peaks on tobacco. From pheromone trap data collected over 5 years, there was a mean of 212 @*D from the first catch of H. virescens males in the spring to the first adult population peak.
