120 Report of State Board of Horticulture. 



formed me that it had never been seen there. The Mcintosh orchard is an 

 old one and showed evidence of neglect, conditions favorable to the de- 

 velopment of the moth had it ever been introduced. Mr. Wirth, who has 

 been a deputy fi'uit inspector of that region, did not know of any codling 

 moth in that immediate vicinity but had heard that it is present in some 

 orchards about the headwaters of Coos river, presumably along the Rose- 

 burg and Coos Bay stage route, as that would correspond with the con- 

 ditions I found on going out by way of the Myrtle Point-Roseburg route. 

 From Marshfield to Myrtle Point, several orchards were noted along the 

 line of the railroad but none were visited. At Myrtle Point I spent one 

 day in examining orchards but found no wormy apples. Mr. T. F. Perkins, 

 a nurseryman of Parkersburg, who has canvassed the county thoroughly 

 each year, told me that the codling moth has appeared at a certain ranch 

 on the Fishtrap between Coquille and Myrtle Point, in the North Carolina 

 settlement on the headwaters of the South Fork and in an orchard on 

 Big Creek near Bridge P. O. Mr. A. H. Black, a merchant who handles 

 a large amount of fruit, reported that "wormy" apples are very scarce, but 

 that a few had been found in the fruit from one orchard near Myrtle Point 

 and one near Norway. One of these orchards was visited later but no 

 codling moth could be found and the owner assured me that he had never 

 seen a wormy apple in his orchard. Near Big Creek, about ten or twelve 

 miles out from Myrtle Point on the road to Roseburg, 1 was informed by 

 two ladies that the codling moth had been present in the orchards of that 

 vicinity for several years past. "In cutting up a pan of apples they us- 

 ually found two or three wormy ones." No more orchards were seen until 

 the home of Mr. L. B. Feller was reached, seven or eight miles farther 

 out on the Roseburg road. Here I found the first codling moth larvae I 

 had seen on the entire trip, and was told by Mr. Feller that they had been 

 present each season for the past three or four years. From Mr. FeUer's 

 place, a ride of some sixteen miles, during which no orchards were passed, 

 took me to Camas. Here wormy apples were to be found in every or- 

 chard, a condition of affairs that proved to be true in the orchards between 

 Camas and Roseburg. 



As a result of this trip I became convinced that at the time (1900) the 

 codling moth was not present, to any great extent at least, in the Coos 

 Bay region. I also became convinced that the present immunity can be 

 accounted for on the ground of isolation rather than that of peculiar cli- 

 matic conditions, and that it is not likely to be permanent. Coos county 

 is a beautiful region, broken, mountainous and timbered. Its only 

 connection with the outside world is by boat, or by wagon roads over the 

 mountains from Drain or Roseburg. The codling moth must of necessity 

 be introduced by one or more of these routes. As shown above, the ab- 

 sence of orchards in the immediate vicinity of Empire and Marshfield, 

 render it unlikely that the moth could obtain a foothold even though re- 

 peatedly introduced at these points in imported fruit. From Drain it has 

 advanced from orchard to orchard nearly to tide-water at Scottsburg, where 

 it has been checked by the absence of other orchards to conquer. From
