Description: Defoliation by the cottonwood leaf beetle, CLB, (Chrysomela scripta F.) can pose a significant threat to the growth and development of one and two-year old Populus plantings. In the southeastern United States, guidelines for monitoring CLB populations at the landscape level have not been fully developed. Accurate determination of when CLB are present in the field could greatly aid in the efficient management of this pest. To address this situation, we compiled data regarding the developmental rate of the CLB to test predictive models of CLB development. Based upon comparisons with field observations, current temperature-dependent growth models hold promise for predicting the occurrence of first generation adult CLB in the field. Prediction of the appearance of specific CLB life stages, especially in subsequent generations, may be somewhat more difficult and requires more examination.
