Note: "A year later, again with a Forest Service grant, I organized a workshop on the European wood wasp, Sirex noctilio, in Brazil. Representatives from eight South American countries participated and it too was the first opportunity for forest entomologists from the region to meet (First South American Forest Insect Work Conference)."
