APPL3 A1E> THOHW SKELETON IZEK ( itemerophiia psria na Clerck) 
Massachusetts A. I. Bourne (October 22): As stated in my last report, the 
apple and thorn skeietoniser showed a very marked increase in 
the brood which normally appears in this State around September. 
This caused a considerable amount of leaf skeletonizing in some 
orchards. It should be stated, however, that cur best growers 
are finding this insect so easily controlled by their regular 
spray schedule that they are not ranking it as a serious post. 
APPLE MAGGOT (Bhagolctis pom on el la Walsh) 
Massachusetts A. I. Bourne (October 22): I want to emphasize again the state- 
ment I made in my report of last month about the very general and 
considerable injury which has boon caused throughout the main apple- 
growing sections of the State by the railroad worm. Of the prin- 
cipal varieties grown in this Stat d, the wealthy, was naturally hit 
the hardest. In one orchard which I visited the grower estimated 
that from 20 to 30 per cent of his supposedly marketable stock was 
found to be infested; practically 100 per cent naturally of his 
drops showed infestation. The trouble was so widespread and so 
serious that many growers found the market was rather suspicious 
of Wealthies. The Mcintosh did not seem to bo badly hit, although 
in some cases some injury was noted. I find that some of the grow- 
ers are finding railroad worm work showing up in their Baldwins, 
which are being harvested at this time (October 15). 
Nebraska M. H.Swenk (September 25 to October 25): A new center of infesta- 
tion of apples with the apple maggot in southern Gage County was 
brought to our attention about the middle of October. 
SA1T JOSS SCALE ( Aspidiotus perniciosus Comst.) 
Indiana J. J. Davis (October 29): Continues as the major orchard problem 
in southern Indiana. This year it is much more abundant and des- 
tructive throughout central Indiana. 
Illinois W. P. Flint (October 19): Recent examination of peach and apple 
orchards in southern Illinois by S. 0. Chandler has shown an in- 
crease in scale in orchards where the pest was not brought thor- 
oughly under control last spring. In some cases tiiees are infest- 
ed and a determined effort will have to be made to control the 
insect this winter. Tor the most part the scale is well under 
control. Practically all orchards in this section of the State 
will be sprayed with oil emulsion again this year. This applies 
to both peach and apple.
