Not just for the birds: Spiders as natural enemies of spruce budworm (Choristoneura fumiferana, Clem.)
The eastern spruce budworm (Choristoneura fumiferana, Clem.) is a native irruptive forest pest that defoliates spruce-fir forests throughout North America’s boreal zone. Past studies suggest that successful spruce budworm population control requires high natural mortality from a variety of sources,...
