The San Jose scale is at present found nearly everywhere in Massachusetts 

 and feeds on 125 or more different kinds of plants. Its natural enemies do not 

 keep it in check, and it is. therefore, necessary to cut down worthless, badly 

 infested trees and burn them and to fumigate or spray other infested trees. In 

 spraying the best results are obtained with lime-sulphur wash boiled from 40 

 minutes to 1 hour. Self-boiling lime-sulphiu' mixtures are less satisfactory. 

 Likewise the K-L mixture has not given success. Proprietary insecticides for 

 the San Jose scale either give poor results or are so expensive as to be out of 

 the question. 



How to control the San Jose scale and other orchard pests, J. Troop and 

 C. G. Woodbury {liidhtint Kfa. Bill. IIH. pp. .iHo-.'i.iJ. pijx. I'l). — Formulas are 

 presented for the preparation of standard insecticides and fungicides, and a list 

 is given of the more important of the insect diseases affecting the apple, cherry, 

 gooseberry, grape, peach, pear, plum, raspberry, blackberry, and strawberry. 



The present status of the San Jose scale in Indiana is outlined and the insect 

 is described. Lime-sulphur wash is recommended as the best treatment for this 

 pest. 



How nurserymen may guard against San Jose scale, F. Sherman, Jr. 

 (A'. C. Crop Pent Vow. Circ. 11. pp. 11). — Brief directions are given for the care 

 of buds and cuttings, the spraying of nursery stock, and other lines of work to 

 be taken up by nurserymen who wish to maintain i)remises free from San Jose 

 scale. 



The cottony maple scale in Illinois, S. A. Forbes {Illinois Sta. Bill. 112. pp. 

 343-360. pis. 3, figs. 8). — The cottony maple scale is seldom injurious to maple 

 trees in natural forests, but causes great damage to trees planted along streets 

 and roadsides for shade purposes. In Chicago it has been injurious continu- 

 ously since 1886. It is particularly harmful to soft maple, but attacks also 

 linden, box elder, elm, and a considerable variety of other trees. The life his- 

 tory and habits of this pest are discussed in some detail. 



A brief summary is given of insecticide work thus far carried (in by the 

 author and others in its control. Kerosene emulsion was applied at a strength 

 of 10 per cent in 1 experiment, and whale-oil soap at the rate of 1 lb. to (5 gal. 

 of water was applied on a single tree. The insecticides were applied in July, 

 and a comparison of the results showed that 33 i)er cent of the scales were 

 killed by an application of kerosene emulsion at the beginning of the hatching 

 period and 82 per cent by 2 applications at the middle and end of that period. 

 Whale-oil soap was somewhat less effective. 



The author concludes that for summer spraying a 10 jx-r cent kerosene emul- 

 sion applied at the middle and end of the hatching period will give satisfactory 

 results. The cost of this treatment for average trees is about 32 cts. each. In 

 experiments carried on in Chicago the average cost for both materials and 

 labor was 43 cts. per tree. 



An application of a 19 or 20 per cent kerosene emulsion during the dormant 

 season caused considerable injury to trees, some of which looked sickly in the 

 spring and others died. The percentage of scales killed I)y the winter treatment 

 ranged from 80 to 01. 



The strawberry weevil in the South-Central States in 1905, A. W. ^lou- 

 RiLL (f. S. Dcpt. \(ir.. liiir. Knt. liiil. 113. pf. I!, pp. .T7-6',M. — Since tlie straw- 

 berry weevil belongs to the same geinis with the cotton-holl weevil it was 

 thought desirable to ascertain whether there were any native parasi^:es of the 

 strawberry weevil in the cotton belt which might attack also the cotton-boll 

 weevil. The study of the subjet-t. as thus far conducted, has been confined 

 largely to a determination of the prevalence and distribution of the strawberry
