Establishment of Agathis pumila (Ratz.) for control of Larch casebearer, and notes on native parasitism and predation in Idaho



Establishment of Agathis pumila (Ratz.) for control of Larch casebearer, and notes on native parasitism and predation in Idaho



USDA Forest Service Research Note, Intermountain Forest and Range Experiment Station (INT-164): 6



Ten years after the release of 2360 individuals of A. pumila at five locations in N. Idaho, the numbers of Coleophora laricella have been effectively reduced at the three locations where the parasite became established. A high degree of parasitization (66% in one location) has been maintained even at low host densities.
