IN the United States 1t is known in
France and Germany as a serious pest
10 pear trees, and us lie history had
'been only recently made out in the lat
ter country. We had to do then with
an imported pest, and l found latel
that it was brought over in pear stocks
about ten years ago
The beetle makes its appearance
about The middle Of May, flies only in
the hottest sunshine, and lays its eggs
IN the bark some time IN June. Early
IN July the very minute larvse may be
found III the sap-wood, and they feed
until winter. becoming by that time
about three-quarters of an inch in
length. Feeding IS resumed in spring
and continues until September, when
the larva Is from one and one-quartar
to one ard one-half inches in length.
It then bores into the solid wood about
one-quarter Of al inch and forms a
cell in which it rests until March or
April, when it changes to a pupa, and
soon afterward to a beetle. Thus the
larva feeds two years in the trees, and
during chat time forms channels from
six to eight inches IN length.
So far as have been able to ascer-
tam. the insect IS still confined to east
ern New Jersey, not extending south
below Elizabeth, but said to extend
northWard INTO Ne" York state. !
have no evidence OF It's presence in the
states OF the central west, but pear
growers who have found it should SO
report THIS is an insect that spreads
