cent. Several pciir orchards have been noted which w(?re located in 
neglected orchards in which there were few or no apples. The second 
generation of the insect seemed to concentrate its destructiveness on 
the pears, and in one case fullv SO per cent and in another about .50 per 
cent were injured. One fruit grower in Texas reports an injur}' of .50 
per cent. 
Crab apples are not usually so l)adly infested, l)ut instances have 
been observed where they suffered fully as much. 
Many records also show that peaches, prunes, plums, cherries, 
quinces, and apricots are infested b}' the codling moth, })ut under 
ordinar}' conditions their injury amounts to practically nothing. In 
cases where there is a lack of apples and the infestation is very 
abundant considerable damage results. There are records of -to per 
cent injury to peaches where the trees were quite near an apple house 
in which infested fruit was stored. 
NTJT-FEEDING HABITS. 
There are several European records of this insect in walnuts and 
oak galls. In 1887 Dr. Howard carefully sifted these reports, and 
concluded that the evidence was not sufficient to delinitely prove that 
the insect ever feeds upon either walnuts or oak galls; and it was 
highly probable that the larvie. if they were larvie of the codling 
moth, went into the latter for the purpose of spinning their cocoons. 
In 1895 Mr. Adkin exhibited a specimen of C. ponumdla which was 
bred from a species of chestnut, and in 1896 gave details as to rearing 
this insect from walnuts, and offers the explanation that these nuts 
bear fleshy coats, or that the insect was originally a nut feeder. 
Theobald in 1896 wrote that in his investigations, extended over many 
years, he had never himself bred CarpocajjsajjoiuoncUa from walnuts, 
but had found both C. splendana and Plodia intei'punctelln. ^Ir. West 
stated that he had also bred the insect from chestnut. 
Dr. Kiley in 1869 recorded that he had a specimen of a moth which 
had been bred from the sweetish pulp of a species of screw bean 
{Stronibocarpa ino)wica) obtained from the Kocky Mountains. Pro- 
fessor Cockerell raises the question of the correctness of this record. 
In 1894 Professor Bruner reported that it is highly prc)])al)le that the 
insect feeds in the seed ])uds of roses. In 1901 the writer carefully 
searched over man\' hundreds of these seed buds of roses near a badly 
infested orchard, and did not succeed in finding a single one that was 
in any way injured by the codling moth. 
LEAF-FEEDING HABITS. 
Professor Card in 1897 recorded that the young larv;e, especially in 
confinement, nibbled portions of the leaf. The writer has noticed 
manv times leaves that had been eaten where he thoui:ht the work
