578 Keport op Entomologists of the 



Mr. Slingerlaiid states* that he sa\v^ the scale at Lockport in 1893, 

 hut not in any such numbers as last year. 



It was not until the spring of 1894 that the scale began its rapid 

 increase.. At that time it was noticed in alarming numbers in certain 

 large plnm orchards in western New York. Further investigations, 

 however, showed a wide distribution throughout the |)lum-growing 

 section of the State. The scales multiplied at a rapid rate duriug 

 the spring, and by the following fall the young scales could be 

 found literally by the millions on infested trees. 



The winter of 1894-95 was a severe one, but although a large 

 number of infested plum trees were examined during the latter 

 part of December, we failed to find any change in the appearance 

 of the scales. Later examinations at Hector and Geneva during 

 the latter part of March, showed a large percentage of the scales 

 dead, except on certain trees and in certain orchards which were 

 protected, in a measure at least, from the severe winds common 

 to these localities. 



At present the scale may be found in many orchards in the State. 

 In some, if not all of them, where proper precaution is not taken, 

 in sufficient numbers to cause very serious damage in case the con- 

 ditions should again be such as to bring about another rapid 

 increase. 



Long Island. — Although we have not observed the scale u]3on 

 Long Island, it is said to be known here. It is certainly very near 

 here, for, as previously mentioned, it is known to occur at present 

 in New Jersey and on Staten Island. In the latter case, a few old 

 plum trees and some quince trees near by were found slightly 

 infested. It will be well, therefore, for Long Island fruit growers 

 to bear this in mind, and to be prepared to stamp the pest out in 

 case it should increase to an alarming extent here. 



The Winter of 1891^-5 . — The following account of our experience 

 in two or three plum orchards situated on the shores of Seneca lake, 

 may be of some interest in showing the effect of the wind and cold 

 upon the scales. 



The first orchard to which our attention was called is situated on 

 the east shore of Seneca lake, about thirty miles south of Geneva, 

 The trees stand on a steep slope such as is common to that section,
