body black banded and marked with golden yellow. Its wings 
when expanded will measure from three-quarters of an inch to 
an inch across. The eggs are deposited by the female during the 
hot summer weather on the canes a short distance above the 
eround. The young larva when hatched eats its way through the 
cane to the center where it feeds upon the pithy substance. It 
gradually channels the cane to the root, in which it spends the 
winter, forming, before the spring, cavities of considerable extent. 
As the spring opens, it makes its way up again, usually through 
the interior of another cane, to the height of five or six inches, 
where the larva, preparing for the exit of the future moth, eats 
the cane in one place nearly through, leaving only the skin» 
unbroken. When full grown it is about an inch long, of a pale yel- 
low color, with a dark brown head. When the time approaches 
for the moth to escape, the chrysalis which the borer has become, 
wriggles itself forward, and, pushing against the thin skin rup- 
tures it, and forcing its way through the opening waits the escape 
of the moth. The injury done to the root is often followed by 
the death of the cane, which is sometimes incorrectly attributed © 
to being the result of severe cold of winter. Little can be done 
with this pest other than uncovering the roots and cutting out the 
infested portions, 
The raspberry cane-borer in its larva state lives in the center of i 
the cane, burrowing downward and often causing the death of — 
the cane. The female moth deposits her egg in June by girdling | 
the young cane near the top in two places, one ring being about 
an inch below the other and between the rings the cane is pierced 
and an egg thrust into it. The presence of this enemy is early 
detected by the sudden drooping and withering of the tips, and 
by removing all the withered tops down to the lowest ring, so 
as to insure the removal of the egg, these insects may be kept 
under. | 
The tree cricket. Probably thisis the most troublesome insect 
affecting the canes of the raspberry. The female cricket lays 
her eggs in the autumn by thrusting her long ovipositor obliquely 
more than half way through the cane, and down the opening thus 
made she places an egg. A second one is then placed alongside 
of the first and so on until from five to fifteen eggs are placed in 
ayrow. An irregular row of punctures indicates the presence of
