Geographic Differences in Recovery and Growth Responses to Cold Stress in Lymantria dispar
This project is comprised of three experiments that were conducted during the summers of 2018 and 2020. In the first two experiments on chill coma recovery, populations of gypsy moth from across the US invasion were reared until their third (2018) or second (2020) larval instar. Larvae were exposed to extreme cold temperatures for 20 hours and time taken to recover motor function upon emergence from the cold environment was recorded. The third experiment was a growth study examining the effects of a cold snap on development. These experiments were conducted to investigate the capacity to which this invasive species can adapt to local climates.
