The insect, being two-brooded in this
climate at least, if not disturbed, has an aggregating force to do
mischief the second time. The progeny for the succeeding year have alone
to depend on the security of this second generation of larvae. As they
may often be found in bark of apple trees during winter, my plan of
destruction is, about the first of July to take woolen rags long enough
to wrap around the trees, and say four inches wide. Each week I look
over the trees, and destroy the worms secreted under the rags and
wherever I find them until the fruit is off the trees. I have all the
green fruit, of every kind, carefully picked up as soon as it falls,
thereby destroying many of the curculio as well as the apple-worms.
One word upon the grape--the insect part of the question. The
_Phylloxera vastatrix_, or grape-vine louse, is already at work on Long
Island. It is found very difficult to raise many of our fine, new grapes
with us in consequence of the depredations of this very minute insect,
it being almost too small to be seen by the naked eye.
