SUMMARY OF DISTRIBUTION AND PRESENT CONDITION. 21 



obscure form of disease as well as to the lime-sulf ar treatment. In 

 southern California it is particularly troublesome in apple orchards. 

 The principal variety of apple grown is the White Pearmain, and the 

 comparatively rough bark of this variety makes it difficult to get very 

 satisfactory results from the lime-sulfur wash. The varieties of apple 

 commonl}^ grown in northern California — for example, Newton Pippin 

 and Yellow Bellflower — are smooth barked, and better results with the 

 wash are gained. Taking the State as a whole, Professor Woodworth 

 says that it will be readily found in at least 25 per cent of the or- 

 chards, in injurious numbers in probably 10 per cent in an}^ one year, 

 and that from 25 per cent to 10 per cent of the orchards are sprayed 

 with the lime, sulfur, and salt wash every 3^ear. 



COLORADO. 



The San Jose scale has apparently not jet obtained foothold in 

 Colorado, but it has been sent to us from Colorado on fruit imported 

 from California. The probable explanation is that the fruit regions 

 of Colorado are above the climatic range of this scale insect. 



CONNECTICUT. 



The San eTose scale is recorded for at least five localities in Bulletin 

 12. The increase of this scale in Connecticut has been pretty rapid, 

 and Mr. W. E. Britton, State entomologist, expresses the belief that 

 there is now no town in the State which is not infested, tho he may 

 not have records from quite all of the towns. It is found very gen- 

 erally, at any rate, in all of the larger cities, which are thoroly 

 infested. Practically all of the larger orchards are infested, tho per- 

 haps only slight l3\ He sa3"S that there are many orchards and trees 

 which are still exempt, but that there is no general region of the State 

 where the scale can not be found. 



DELAWARE. 



Delaware, as recorded in Bulletins 3 and 12, became generally 

 infested very early. Mr. Wesley Webb, secretary of the State board 

 of agriculture, now informs us that the San Jose scale occurs in all 

 parts of Newcastle County and in approximately one-half of the 

 orchards. In Kent Count}^ there are many young peach orchards, 

 and more than one-^'"-a^ii^>'^em are infested to a greater or less extent, 

 a large proportion of them, however, only slightl^^ so. In the western 

 half of Sussex County, along the railroad from Farmington to Delmar, 

 nearly half of the orchards are somewhat infested, while in the east- 

 ern half of the county from Lincoln southward there are but few 

 orchards, and these are comparatively free from scale.
