Abstract:

We selectively removed seven rows from a 10-row shelterbelt. Overall shelterbelt width was reduced by 47%, and leaf and stem litter was reduced by 84%. Anthonomus grandis Boheman survival was not completely eliminated. However, overwinter survival rates were significantly lower and spring emergence terminated earlier in managed plots as compared with that in check plots. Reduced survival rates and earlier termination of spring emergence appeared to be related to modified temperature patterns in the managed plots. Also, significantly fewer fall-migrating A. grandis selected managed plots as overwintering quarters as compared with the check plots. These results indicate that shelterbelt management could be used to effectively reduce, and perhaps eliminate, overwintering A. grandis in this habitat type. The reduction in number of tree rows did not adversely affect the windbreak function of the shelterbelt.
