REPORT OF THE ENTOMOLOGIST. 99 
can be used with any degree of success in fighting the Codling Moth, 
and I have good reasons for so doing. During one whole summer, 
three years ago, I had a patent moth-catcher constantly in a garden 
surrounded by several old apple trees badly infested with this insect, 
and I never caught a single specimen of Carpocapsa pomonelia. The 
trap was made of bright tin, with an inverted cone so placed in a 
basin that I could attach a light and fill the basin with sweetened 
fluid. Again, during the summer of 1870, 1 was in the habit of 
working till late at night in an office surrounded by apple orchards 
known to be badly infested. I worked by the aid of two large 
kerosene lamps, each having a strong reflector, and the light in the 
room was so bright as to form a constant subject of conversation 
among the neighbors. Insects of one kind and another would fly 
into the room by hundreds, and on certain warm, moist evenings 
would beat against the windows with such rapidity as to remind one 
of the pattering of rain. Yet, during that whole summer I caught 
but one or two Codling Moths in that room, and there was more 
reason to believe that they had bred in the house than that they were 
attracted from without. 
“‘Atthe same time I had hung up in an orchard close by, many wide- 
mouthed bottles, half-filled with various liquids, such as diluted 
sirup, sugar water, and vinegar more or less diluted. Every two or 
three days these bottles would contain great numbers of insects, 
which were critically examined. Many of them would be small 
moths of one kind and another; some or them larger moths, known 
to be injurious, and many other insects—such as beetles, true bugs, 
wasps and two-winged flies—that were beneficial. Indeed, there were 
almost as many beneficial as injurious species, and, as I shall presently 
show, the only two species yet known to prey on Carpocapsa pomo- 
nella were among the more numerous Victims of these hanging bot- 
tles. Frommy notes I find that but three Codling Moths were caught 
in these bottles during the summer. Indeed, so small is the propor- 
tion of Codling Moths which I have caught by the above-mentioned 
process, that the chances of their accidentally flying into such situa- 
tions are about as great as of their being attracted. I might add fur- 
ther experience on this head, but it is unnecessary. Upon showin 
specimens of the Codling Moth to many dozens of eminent and intelli- 
gent fruit-growers who have had to do with apple orchards, and con- 
sequently with apple worms, most of their lives, Ihave seldom found 
one who did not candidly confess that he had never before identified 
the insect; and under these circumstances it is not surprising that 
other similar moths should have been mistaken for the genuine article. 
The moth is, therefore, occasionally caught in such traps, and in 
the face of other intelligent testimony the fact can not be denied, 
though the experience on this head of non-entomologists is conflicting. 
But whether we consider that the few so caught are really attracted, 
or are captured accidentally, I believe that the methods indicated have 
no practical value. They are blind ways of shirking the more sure 
and efficient remedies. 
*T have been thus explicit as to these would-be remedies because 
my statement ‘that the Codling Moth was not attracted (to sny ex- 
tent) by light’ has béen recently quoted by Mr. J. W. Robson as an 
evidence ‘that scientific men don’t know everything.’ It would be 
strange indeed if they did, and I have already labored under the im- 
pression, somehow or other, that they were the last to claim any 
such universal knowledge, and that it was the charlatan alone who
