The use of chemical insecticides is presently accepted as the most effective means of keeping damage by spruce budworm in Maine at an acceptable level. Unfortunately, broad-spectrum chemicals such as Sevin-4-oil® affect non-target organisms as well, and this can have serious consequences. The significance of these effects can only be determined by monitoring populations of non-target organisms and assessing the overall impact on the environment. This study was undertaken to determine the effects of operational spraying of carbaryl insecticide, Sevin-4-oil® on the abundance of insect pollinators in a spruce-fir forest.
