MISCELLANEOUS NOTES ON INJURIOUS 
INSECTS.* 

V. H. Lows,

SUMMARY. 
The forest tent-caterpillars were again very abundant during 
the spring of 1900, causing serious injury to forest; shade, and 
fruit trees. Arsenite of lime, arsenate of lead and Paris green 
were successfully used in combating them. The application was 
more effectual when made soon after the caterpillars had hatched 
than after they had become half grown. In villages and cities 
they were dislodged by streams of hydrant water and prevented 
from returning by sticky bands or other obstructions fastened 
about the trunks of the trees. — 
In some sections of the State the fruit bark-beetle has caused 
Serious injury by working in the bark of healthy fruit trees, 
especially peach, cherry and plum. The numerous punctures 
caused a copious exudation of sap. This injury was noticed 
about the first of August. Eggs and larve were found late in 
the fall in the small twigs and branches. Much can be done 
toward controlling the insect by applying a wash to the trunk 
and larger limbs late in July and trimming out and burning the 
infested branches during the winter. 
A species of mealy-bug was found on quince trees in sufficient 
numbers to cause slight injury. It can be successfully combated 
by applying a solution of whale oil soap, one pound to five gallons 
of water. -
