Summary: The objectives of this project were: 1. Examine the role that female and male mate choice plays in the mating success of CM and OBLR. 2. Examine the effect of male age on female reproduction in CM. 3. Determine if the delay in mating should be calculated on a calendar or a degree-day basis, and determine if we can predict severity of CM and OBLR problems based on the average delay in mating experienced during the spring related to weather patterns. 4. Investigate the importance of CM dispersal between MD and non-MD areas.
