ticed hand picking of the beetles, but the process would be entirely 
impracticable upon any number of trees. The winged beetle ap¬ 
peared to be more of a crawling insect than a flying one, which sug¬ 
gested the possibility of protecting young grafts by placing bands of 
“Tree Tanglefoot” or other adhesive bands about the tree trunks 
to keep the beetles from ascending in the spring. 
MISCELLANEOUS OBSERVATIONS. 
A great many other injuries to fruit or field crops by insects, 
rodents, etc., were observed through the season. . 
\ pink-bodied aphis of undetermined species was found doing con¬ 
siderable damage to peach buds, blossoms, and young fruit early in 
the spring. Specimens were first seen April 13, at which time peaches 
were showing first bloom. The larger, flat-bodied, pinkish aphis first 
observed gives birth to young, which cluster about the blossoms and 
about the forming peaches, still very small sucking f F 0 ^ 
sap and causing many to fall to the ground. Later m the season, 
peach leaves are curled up by the aphids, but all seem to d jsappw 
late in May. The injury is thus done early in the season at the time 
fruit is setting. Application of the lime and sulfur wash just before 
the buds open is suggested as a means of control, and this and ot e 
measures of treatment will be tried in an experimental way the com- 
• • 
Observations were also made upon aphids infesting plums, elms, 
Injuries to cantaloupes were noted, caused by leaf miners, the 
common red ant of the prairies, and prairie dogs. In some orchards 
the green fruit worm caused injury to from io to 25 per cent of the 
young forming apples, but in orchards receiving proper codling moth 
spraying the injury is much less severe or reduced beneath 
A pear leaf blister mite, probably of a different species from 
that causing the injury in Eastern States, was observed in great num¬ 
bers through the summer, causing the blackened curling of the pear 
leaves at the tip of the twigs, as well as producing minute blisters 
upon the leaves and causing them to drop from the trees prema¬ 
turely. It is thought that a late spring spray with the lime and sul¬ 
fur wash will also control this pest. . , 
Other orchard pests observed, studied, or experimented upon 
in attempt at control were the buffalo tree hopper, tent caterpillar, 
hawk moth larvae, grasshoppers, thrips, brown mite, pear and cherry 
slug, terrapin scale, Putnam scale, and numerous parasitic or preda- 
cbus insects doing beneficial service in the orchards.
