Available in PDF, EPUB and Kindle. Book excerpt: Some field studies of the effects of various insecticides on the spruce budworm (Choristoneura sp.) and their parasites have shown severe suppression of host (budworm) populations and increased parasitism after treatment. Computer simulation using hypothetical models of spruce budworm-parasite systems based on these field data revealed that (1) effective parasites produce greater stability in budworm populations than ineffective ones and are more resistant to changes induced by insecticides; and (2) the level of budworm population suppression in most budworm·parasite systems is not proportional to the amount of insecticide applied. Only high insecticide dosages produce any effect on the budworm population. Cost-benefit analyses showed that very high investments are worthwhile, but moderate investments produce little effect. The study demonstrated that the computer simulation pmcess helps to define kinds of information needed for understanding the budworm-parasite system, and can predict system behavior under varying conditions.
