the United States during, the past few years and we have drawn 

 freely from their pages, discussing the facts, however, in the light 

 of Montana's conditions. Observations by the writer been incor- 

 porated also. 



POPULAR NAMES. 



It is proposed here to draw attention to the fact that the name 

 and spelling employed at the head of this article is the one now in 

 general use and believed to be the correct one. Some persons in 

 Montana employ the name "Codlin" moth. Prof. Slingerland of 

 Cornell University several years ago made an extended search into 

 the literature of this question and arrived at the conclusion that the 

 name "Codling" deserved preference. Some persons having in mind 

 the larval stage of this insect use the name "apple worm" or "fruit 

 worm", but while the use of this name is excusable, it is less desir- 

 able for the reason that it overlooks the fact that the moth and the 

 larvae are of the same species. 



GEOGRAPHICAL DISTRIBUTION AND OCCURRENCE IN MONTANA. 



The original home of the apple is southeastern Europe and it 

 is supposed that in prehistoric times the codling moth fed upon wild 

 apples in a natural state. With advancing civilization the apple 

 has been introduced wherever man has gone and the codling moth 

 has closely followed and besides now occuring throughout the 

 United States and in Canada wherever the apple is grown it is 

 known to be present in Europe, Africa, New Zealand, Australia and 

 Brazil. Mr. C. L. Marlatt during his etensive travels in Japan 

 and China a few 3'ears ago did not observe this insect there but more 

 recently Prof. A. B. Cordley of Oregon has learned, probably 

 through correspondence, that it has reached China. 



In Montana the codling moth has been authentically reported 

 from Thompson Ealls, Missoula, Hamilton, Woodside, Kalispell, 

 Big Eork, Helena, Forsyth, Park City, Billings and Joliet. The 

 orchard industry is still young in Montana and the codling moth 

 has not yet done a great deal of damage, though it has plainly shown 

 its ability to exist in Montana's climate and to be very injurious. 

 in Missoula where the State Board of Horticulture has been faith- 

 ful in endeavoring to stamp it out or reduce it to the smallest num- 

 bers, it was still to be found in considerable numbers last summer
