Abstract

Correlation coefficients were calculated for the estimates of insect density obtained by radiographs versus dissection, and for the estimates obtained by radiographs versus radiographic guided dissection. Estimates of numbers of siricids in white fir obtained by the two methods were closely correlated. The radiographic methods are more accurate than dissection alone, and also faster and cheaper.
