SUMMARY. 
A brood of the periodical cicada is due to appear this spring. 
It is located in Niagara, Monroe, Kings, and Richmond counties 
in this State, and in 18 of the central, southern and eastern 
states and the District of Columbia. It is probably the largest 
of the 17-year broods. The adult females injure trees, shrubs 
and vines by puncturing the twigs and small branches in order 
to deposit eggs in the wood. The injury is not usually serious 
except when the insects occur in very large numbers. There 
seems to be no practical method of destroying the adults when 
occurring in sufficient numbers to do serious injury. 
The palmer worm was very abundant in some of the apple 
orchards in western New York during the spring of 1900. It 
has practically disappeared and is now found only occasionally. 
The insect has been noted as a species that appears suddenly 
in large numbers and disappears as quickly as it came, not to 
appear again for several years. 
White grubs were found very destructive to aster plants 
grown in the field. The same field was in nursery trees the 
season before and while the grubs had not injured the trees 
sufficiently to be noticed, they were there in sufficient numbers 
to cause serious injury to the asters. The only practical remedy 
found was to pull up the infested plants and destroy the grubs.
