The nutritional value of twelve species of wood to the Formosan subterranean termite was studied. Incipient colonies of Coptotermes formosanus were reared in 50 X 9 mm petri dishes with 3g of dust from each wood species and 70% distilled water. Alate stages of C. formosanus were collected by light trap and allowed to pair in the lab. A total of 720 pairs were selected (60 per treatment), placed inside the petri dishes and reared at 27°C, 95% RH, and total darknes. Survival of pairs was monitored every 15 days for the first 6 months and montly for the next 6 months. Progeny was counted monthly for the first 3 months and then at 6 and 12 months. The highest survival was observed in douglas fir, aspen, and red gum treatments; however, the highest fecundity was observed in the Pecan and red gum treatments. The highest mortality and lowest fecundity were observed in bald cypress, Southern yellow pine, ponderosa pine, and ash.
