ond brood. These are sometimes very abundant in late summer 
and in autumn. The adult is a small brown moth measuring 
about # of an inch from tip to tip when the wings are spread. 
Those who wish an exhaustive treatise on this insect should 
consult Prof. Slingerland’s bulletin.® 
Treatment.—A considerable percentage of the worms can be 
killed by spraying within the first week after the blossoms have 
fallen. The calyx end of the fruit must be filled with the poison 
before the calyx lobes close, hence much pains should be taken 
to make at least one thorough application before that occurs. 
GREEN FRUIT WORMS. 
(Xylina sp.*) 
Descriptions.— These insects sometimes do serious injury by 
eating into the young apples. They also attack pears, plums, 
peaches and quinces. The full-grown caterpillars measure from 
an inch to nearly an inch and a half in length. They are green 
or yellowish green in color with various irregular markings and 
stripes, the most prominent of the latter being a narrow, cream- 
colored one down the middle of the back and a wider one along 
each side. 
The caterpillars are most abundant during May, soon after the 
fruit has formed. They continue feeding until about the middle 
of June. They feed mostly at night, resting on the under sides of 
the leaves during the day. When full grown they go into the 
ground, form a rough cocoon and pupate. The adults, which are 
dull-colored moths measuring about two inches from tip to tip 
with the wings spread, come forth in the fall and remain over 
winter in some sheltered place, laying their eggs in the spring. 
Treatment.— These insects have proven difficult to control.
