The use of Paris green in these preparations causes a similar 

 thoui^h less extensive injury. 



The leaf blister mite, Eriophycs pyri Nal., which was 

 studied recently by Parrott, and which has caused considerable 

 damage to apples in New York State, is present in Connecti- 

 cut apple orchards. We observed it at Meriden, where it 

 has been noticed for at least two seasons. Samples were sent 

 to my office from Litchfield, Xew Britain, Ellington, and 

 Cummington, Mass. During the past summer this pest was 

 so prevalent in certain apple orchards in ^Massachusetts, which 

 I visited, that one-third of the leaves had dropped from the 

 trees. It has long been known as a pest of the pear, but 

 recently apple trees also are attacked. The best treatment, 

 according to Professor Parrott, is to spray with a lime-sulphur 

 mixture just before the buds open in spring. 



There are many indications that the San Jose scale is 

 losing its virulence or power of spread and injury to the trees. 

 Several instances have come to my notice where old apple 

 trees which were infested several years ago, and which I 

 thought would be dead before this, have taken on a new 

 lease of life, and on examining them, very few living scales 

 could be found. There seems to be no particular parasite 

 that is responsible for the check of the scale. The commer- 

 cial lime-sulphur preparations have been used extensively the 

 past season, and now nearly every insecticide manufacturer 

 has a brand on the market. Oil preparations are also being 

 used with success. 



Excellent progress has been made in controlling the gypsy 

 moth. At Wallingford last winter 8,234 egg-masses were 

 found and destroyed. In the summer 10,000 trees were 

 banded with burlap, 365 with Tree Tanglefoot, 904 trees were 

 pruned, nearly 2,000 cavities in trees filled or covered, several 

 hundred trees sprayed, and 8,^^*36 caterpillars killed under the 

 bands. Besides, several thousands of young caterpillars were 

 killed by the spraying, and perhaps as many more caught in 

 the stick\ bands. In scouting; the whole of the infested area
