SUMMAEY OF DISTEIBUTTON AND PRESENT CONDITION. 29 



OKLAHOMA. 



The first records of the San Jose scale in Oklahoma were received 

 in 1904, on Japan plum from Mulhall. We have since received it, in 

 1905, on peach from Stillwater and El Reno. Mr. J. F. Nicholson, 

 entomologist of the agricultural experiment station, reports that the 

 scale has been found to a limited extent in five places in the Territory, 

 namely, Mulhall, Shawnee, El Reno, Wellston, and Chandler. All of 

 these cases are trees in cit}^ gardens. 



OREGON. 



Mr. A. B. Cordle}^, referring to present conditions in Oregon, states 

 that to enumerate the localities where the San Jose scale is found would 

 be practically to include all places where fruit is grown. He sa3^s that 

 it occurs in a very large proportion of the orchards in western Oregon, 

 from Ashland to Portland, particularly those along the lines of rail- 

 roads or in the vicinity of towns, there being scattered orchards back 

 toward the foothills which the San Jose scale has not yet reached. It 

 occurs also between Portland and Astoria, along the Columbia River; 

 is present in the Hood River Valley; in the Walla Walla Valley in the 

 vicinity of Milton and Free water, and in the Grande Ronde Valley in 

 the vicinity of Vale and Ontario. There are, however, large areas of 

 central and southern Oregon, remote from the railroads, where little 

 fruit is grown, that the scale has not yet reached. It is noted, how- 

 ever, that the scale does no great injur}^ except in small farm orchards 

 or those that are neglected, and that in all the large orchards the lime, 

 sulfur, and salt mixture as a winter spray is in general use. 



PENNSYLVANIA. 



The San Jose scale became early established in Pennsylvania from 

 New Jersey nurseries, bul, the subject of San Jose scale control was not 

 taken up as earl}^ in this State as in neighboring States, so that the 

 conditions at the outset were not well known. Both Prof. H. A. Sur- 

 face, economic zoologist of the State, and Mr. George C. Butz, the 

 horticulturist of the agricultural experiment station, agree in the state- 

 ment that the San Jose scale is now so widespread in Penns3dvania 

 that there is scarcely a county that has not points of infestation. It 

 occurs in practically all the important fniit regions of the State, and 

 in many private and public grounds, especiall}^ in the portion of Penn- 

 sylvania lying east of the Allegheny Mountains. Mr. Butz reports 

 that probably 20 per cent of the orchards are more or less infested. 

 Professor Surface has, with the assistance of 30 inspectors, taken up 

 active warfare against the scale, inspecting orchards and nurseries and 

 trees in parks and giving demonstrations in methods of suppressing 

 it. He states that he has not found the scale in the three northeastern
