“The moths are going to come and we are going to have to learn to get along with them,” said committee member Robert Dennis, noting that expensive spray programs have not been an effective deterrent in the states to the north. “There are higher priorities for spending this county’s tax dollars than killing moths!”
‘To me, we should be doing more of a planning and education type thing at this point,” said Mr. Wood. “We shouldn’t be doing surveys other than keeping abreast of what’s happening at Chester Gap. That’s where the problem areas are going to be first - right along the crest of the Blue Ridge. I don’t think the moths are going to be a problem anywhere else in the county right away.”
In the interval before female moths reach here in large numbers, breed and begin to deposit egg masses, a plan for coping with the caterpillars should be developed, according to the forester. Critical areas where defoliation is to be prevented ought to be identified, he said. And policy decisions should be made on what exactly will be done in those areas: either spraying with the chemical control Dimilin (which achieves a 98 percent mortality rate) or with the biological control Bt (Bacillus thuringiensis, which has a mortality rate of 70 to 80 percent).
