NOTES FOR THE YEAR 



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. 



FRUIT TREE 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.
