<DIV><FONT face=Arial size=2>Four insects have been a real problem in parts of
Massachusetts in recent years. Larvae of the winter moth were active this
year on the American chestnut tree in Orleans that we pollinated a few
years ago. Large Silver maple trees at our Harwich Port house were hit
hard by the winter moths. Most leaves that survived were severely chewed
and looked lace like. With the abundant rainfall of last spring,the trees put
out new leaves and the trees looked normal the rest of the summer and
fall.</FONT></DIV>
<DIV><FONT face=Arial size=2>There was a sever outbreak of 17 year cicadas along
the south side of the Cape Cod Canal last summer. The adults cut into twigs to
lay eggs and then the twigs die. Some of the oaks lost almost all of their
foliage and then died.Out breaks of Gypsy moths and Forest tent caterpillars
occurred in places.</FONT></DIV>
<DIV><FONT face=Arial size=2>Where trees were defoliated early in the season by
winter moth and then again by the other insects after putting out new
leaves, or by several years of defoliation, trees died. There are a lot of
dead oaks along Rt.495 south of Rt. 24.</FONT></DIV>
