Consideration of biological control programs against several forest pests leads to the conclus1on that no part1cular strategy is completely applicable to all cases. Results will depend on the interaction between the host and the control agent or agents. and this in turn is determined by inherent characteristics of both. In each case it ,will be necessary to make a complete and careful study to determine the best technique. Studies should be continued through low populations as well as during outbreaks 1n order to understand why the regulating agents lose control to the extent that outbreaks develop: . If the use of chemicals becomes necessary in emergencies,it should be kept to minimum level and should be discontinued as soon as possible in order that the natural control agents may have a chance to become re-established.
