Probability density functions for the various within-tree developmental life stages of D. frontalisare derived. The differences between some of these distributions are discussed. The possibility of the existence of a negative feed-back mechanism which enables the beetle to make optimum utilization of the available resources is proposed. In addition, the concept of an optimum location on the infested bole where the environmental (tree) conditions are such that maximum survivorship occurs is advanced. |
