"Shape up and Ship out: Do Bt-Resistant Corn Earworm Moths, Helicoverpa" by Sarah Barclay
Evolution of resistance within insects to pest control has frequently resulted in changes to the organism’s morphotype, including changes in wing shape. By measuring these changes, it is possible to distinguish resistant from non-resistant populations. Geometric morphometrics (GM) quantifies morphological variation within and among populations, it has been used in previous studies to identify changes in morphotype and distinguish between resistant and non-resistant populations of insects.
