REPORT OF THE STATE ENTOMOLOGIST I9Q12 93 
NOME SskOR TEE YAR 
An interesting case of myiasis interna was reported from Kings- 
ton. The infestation presumably arose from canned sardines which 
had probably been left exposed for a time, since four out of six boxes 
examined contained eggs or larvae within the body cavities of the 
fish. This is more probable than to assume that the infestation 
occurred prior to the sealing of the cans. From the material sent us 
the common house fly, Musca domestica Linn.,, was reared. 
The following brief accounts relate to some of the more injur- 
ious or interesting species coming to our attention during the year. 
PRUID CREE INSECTS 
Fruit tree bark beetle (Eccoptogaster rugulosa 
Ratz.). This common pest, a small, brownish black beetle, about 
one-sixteenth of an inch long, displays a 
marked preference for sickly or dying limbs 
of peach, plum, pear and apple in about the 
order named. The feeding holes made by 
the beetles in peach bark frequently bleed 
freely and as a result there may be numer- 
ous masses of gummy matter adhering to a 
rather large portion of the trunk or limb. 
The beetle makes a gallery about an inch 
long, deposits eggs on either side and the 
grubs hatching therefrom make irregular, 
obliquely transverse galleries for a distance 
of about half an inch or more, the full- 
grown grub changing to a pupa at the ex- 
tremity of the boring and emerging through 
a circular orifice. The pests are frequently 
so abundant as fairly to destroy the inner 
bark and outer sapwood, and on deserting 
the tree the numerous circular exit holes 
give the bark an appearance of having been 
riddled with fine shot. It is on this ac- 
count frequently termed the shot-hole borer. 
There are at least two generations annually. 
This pest is best controlled by promptly 
cutting and burning all sickly or infested 
limbs. It is very bad orchard ‘practice to 
allow trimmings to lie around, since brush
