Trade-off between mobility and fitness, exemplified in the codling moth

The costs of being mobile in an insect have evolutionary as well as applied consequences. Two codling moth strains with contrasting levels of mobility were attained through bi-directional selection, using computer-linked actographs. Results provide empirical evidence for a trade-off between mobility and fitness. Evolutionary consequences and implications for pest management (SIT) are discussed.
