Climbers need supports, and those not DIS
posed 10 cling should be tied to the trcllis or
other object


James W Robinson of Fremont, H.. an eX
President of the Illinois State Horticultural
Society, gives the following mode of dealing
with this destructive insect;
The eggs are desposited in the bark at the
tree, the beetle puncturng or splitting the bark
of the tree upwards and dnwnwards and llt
tie sdewlse, the punc,uring looking very
much rs ii made with an ordinary pocket
knife The eggs are usually injected into this
puncture so deep ~ to be out of sight, but not
always. On young and thin barkcd trees the
eggs will he pushed in next to the wood, but
in older and thicker barked trees, they Will on
" be through the hard outer bark and the IN
ncr soft bark.
AS soon rs the eggs begin 10 hatch, which is
IN few days after being deposited, its enlarge
ment causes the puncture to open, and thereby
it is much easier to be detected, The young
borer matches out in the inner side OF the egg
and eats circular piece the size of halfdime,
and then starts off, boring upward at first but
sometimes sidewise or downward. AT this
stage of development it is easy to detect the
young depredalor 10y few drops of discoored
juice of the tree eXuding from the puncture
and sticking on the bark. The larva usually
bores down below the ground surface to win
ter, and up again in summer living In the
larva state nearly two years then, boring out
round again.
The remedy | have successfully used is to
keep the ground around the trunks ofthe trees
clean and mellow, So that there will be no
cracks or openings there for beetles to get IN
to lay their eggs IN the tree, and so that the
puncture where the eggs are laid or young
beetles Matched, may be easily seen, and eggs
or insects destroyed, which can be done, while
the egg, 10y merely pressing firmly on the pune
ture with knife blade (thc cracking OF the egg
can be heard distinctly and if Matched by
cutting away the dead bark over the little cav
lty first eaten out, and killing the young worm.
The borers do not go into the wood much
the first year, and can be easily followed with
the knife; but if not taken out soon after hatch.
ing they seriously injure, if not entirely kill
the tree, especially when they run around just
under the bark, as they sometimes do; or,
when several borcrs are in small tree, they
so lnjure it that it breaks over with the wind.
If the ground is well cleared and patted
down smooth around the trees about the last
of June the destroying of the eggs and young
bOrers will be much more certain
The trees should be examined twice or per
haps three times year, if the borcrs are very
numerous, IN order that the first Matched may
be killed before they do serious injury to the
trees August, September and October are the
months in which to destroy them. They seem
TO inicst certain parts of an orchard from year
to year, while other parts are comparatively eX
empt Low grounds have been more infested
with them than higher parts of the orchard. \
man can usually examine and kill all eggs and
bOrcrs in 800 or more trees per day, if the
ground has been properly prepared and no
work in my orchard has been so absolutely
necessary
