APPENDIX C. 
REPORTS, PAPERS AND ESSAYS PREPARED FOR, BI'T NOT PRE- 
SENTED AT, THE WINTER MEETING, JANUARY 187TH, 1876. 
REPORT OF THE COMMITTEE ON ENTOMOLOGY. 
Minnvapouis, Minn., 17th of First Month, 1876. 
To the President and Members of the State Horticultural Society : 
I exceedingly regret my inability to be present at the winter 
meeting soon to convene in Winona. And still more do I regret 
that my time and the state of my health will not permir my pre- 
paring a paper upon my favorite subject, entomology, that might 
be of interest to all horticulturists. In afew words, however, allow 
1e to speak of that insidious little pest, the apple moth, sporting 
Ae name ‘“‘ Carpocapsa Pomn-ella,” and which belongs to the great 
order Lepidoptera, and of the tribe Tortricidae. The fact has to 
be acknowledged that this, the most beautiful moth of the beautiful 
tribe to which it belongs, is with us in vast numbers, and like many 
others of the “Insects Injurious,” we have to say that their 
ancestors were imported, and the increase has been rapid; and 
wherever apple-growing has been attempted, we find the apple-worm 
pretty generally diffused. 
Isaac P. Trimble, the distinguished Entomologist of the Ameri- 
can Institute of Horticulture, has devoted much time, patience and 
labor to consideration of the habits of this moth, whose forewings 
are of a beautiful ash-gray and brown in wavy alternate streaks, 
with a large, tawny brown spot, streaked with bright bronze or 
gold. 
In some sections of the United States this insect is two-brooded. 
I have not carried my investigations sufficiently far to determine 
whether this is the case or not. I should think, however, that there 
is but one brood during the season. 
From the time the egg is deposited (which is done almost as soon 
as the apple is formed) in the calyx or snuff-end of the apple, until 
the larva is full-fed, is about five weeks.
