_ Dr. Borden says most
forest companies have
responded to the ban on
chemiéal pesticides by at-
tempting to remove logs
from the forest: as soon as
they are cut and before they
can be infested by the
ambrosia beetle. They have
also tried spraying logs with
‘afine mist of water since the
beetles dislike. attacking wet
logs. Although this method
is successful, it is somewhat
impractical.

Borden's project revolves

that the company concerned

“In other field test un-
