etr;ne ON the upper side of the tore
wing. The majority of the moths VIII
e,neroe about week after the petais
fall the exact time depending on the
weather conditions. IF the weather is
warm, egg-laying begins in four OF
five days, but of course, If the weather
is cold and damp the moth may remain
inactive for considerable PERIOD.
The life of the moth covers PERIOD
of nine to thirteen days. The egg is
flat, oval shape and most OF the eggs
of the first or spring generation are
laid on the surface of the leaves. Inc
egg is about half the size OF pln-neau
and matches in six to ten days. Wniie
the eggs of the later generations VIII
hatch in much shorter periods, because
of the warmer weather.
The egg Matched, we get the iarVa'
which is matter of great Importance
from the standpoint Of control.
The newly Matched. larva are about
Ia sixteenth of an inch long, are OF
wbitish color, with black head. Iney
usually crawl directly to the frnt'
which in the majority OF cases tney
enter at the blossom or calix end, al
ter feeding slightly in the caiyx cup
! it goes into the apple, generally TO tne
core. When nearly full grown the
Jarva eats out directly to the sur
face. but keeps the opening plugged
until it is ready to leave the fruit.
Time spent in the fruit of this brood
is about thirty days. The full grown
!, larva is of pinkish white color, wniie
its head is of dark brown.
4 After leaving the fruit it crawls to
creyice and turns again into the
, pupa state in about week, :wnicn
in about. ten days give rise to a brood
: of moths which lay the eggs for the
, second generation. The number OF
5 generations vary, and is a. difficult
al question to solve. owing to the over
r Tapping of the broods.
s The means of control is by spraying
e with an arsenical poison. In spraying
e for this insect, as have already men
k toned, the majority of the young lar

II At this time, if an arsenical poison
II is thoroly applied with enough force
II to drive the poison into the calyx cur

II longer, when it is impossible to place

second time and the correspondent
sprays, if any, should be determine
by the orchardist. He can tell frol
when he saw the first larva from tn
first generation, about the time ths
this generation will reproduce, and b
so doing he can Judge best for himsel
when the second and correspondent
sprays should be applied.
Arsenate of lead is the standar
poison used against the Goblin mot
and much depends on the thorones
