58 EXPERIMENT STATION RECORD. 



An accniiiil is ]irt'S('nt(il of tlie (lislril)iitiini nf tlic insect, itn natural enemies, and the 

 artificial remedies to ))e adojited in controliini; it. These remedies include spraying 

 with arsenical insecticides, such as Paris <;reen, Ixjiidon i)urj>ie, and white arsenic 

 conijiounds, and handing the trees. When these remedies are applied intelligently 

 from 85 to 9S ])er cent of the fruit is saved, while without the application of any 

 remedial measures from Hr> to 100 per cent of the fruit >)ecomes infested. 



Tavo common scalo insects of the orchard, W. E. Brittox ( fonnedicul Si'ilr 

 Sta. Bill. 14.3, pp. 10, ph. 2, Jigs. 5). — Bifilogical and economic; notes are given on 

 scurfy bark-louse an<l oyster-shell bark-l(juse. There is but 1 generation of these 

 scales in Connecticut. The scurfy bark -louse is chiefly injurious in nursery and rows 

 of newly set orchards, while the oyster-shell bark-louse is said to l)e found on nearly 

 every old ai)ple tree in Connecticut. Applications should be made during the first 

 half of June or just after the eggs hatch. For this i)urpose common soap at the rate 

 of 1 lb. in S gal. of water, or kerosene emulsion may be used. 



Report of the inspector of San Jose scale, 1902, G. E. Fisuku ( Toronto: Onta- 

 rio Jh'pt. Aar., IHO.I, jip. J4). — The antlior <liscusses the general status of the iSan Jose 

 scale problem in Ontario and gives notes on the entomological discussions held at 

 the Pittsburg meeting oi the Association of Economic Entomologists. Brief notes are 

 also given on nursery inspection, municipal inspection, and the distribution of whale- 

 oil soap, iTude petroleum, lime-«ulphur-salt, and other insecticides to the owners of 

 infested orchards. The experiments conducteil by the author during the season 

 included tests of whale-oil soap, fi.sh-oil emulsion, crude petroleum, crude oil and 

 soap, lime-sulphur-salt wash, fumigation, and other methods for the destruction of 

 the i^an Jose scale. Whale-oil soap was found to be an effective but costly reme<ly. 

 An emulsion of fish oil, with or without potash, proved quite satisfactory. Diluted 

 crude oil also proved to be an excellent remedy, but undiluted crude oil should be 

 applied with care. Lime-sulphur-salt wash gave excellent results and was found to 

 be quite safe for any kind of fruit trees. Formulas are given for the preparation of 

 these various insecticides. 



The scale insects of the lesser Antilles, II, H. Maxwell-Lefroy (Imp. Dept. 

 Ayr. TIV.s/ Indies, PcmphJet 22, 190S, pp. 50, figs. 47). — In this pamphlet the author 

 continues his discussion of the scale insects of the Lesser Antilles, 31 species being 

 dealt with. This makes a total of 51 species which are at ]>resent of economic 

 importance or likely to ])rove so in the West Indies. Notes are given for the pur- 

 pose of rendering identification of these spe('ies comparatively simple for fruitgrow- 

 ers, and apiiroved remedies are briefly discus'?ed. 



Scale insects of the West Indies, H. IMaxwell-Lefroy ( West Indian Bui., 3 

 {1903), Xo. 4, pp. 295-319). — Notes are given on the native and introduced species 

 of scale insects in the "West Indies and lists are presented of these species, together 

 with others which are likely to be introduced into foreign countries from the West 

 Indies. Special attention is given to the habits, food jjlants, predaceous and para- 

 sitic enemies, fungus diseases, and means of controlling these insects. 



Scale insects and mites on citrus trees, C. L. Marlatt ( V. S. Dept. Agr., 

 Farmers^ Bid. 172, pjp. 43, figs- 34). — This bulletin contains in a condensed form 

 material already published on the same subject in the Yearbook of this Department 

 for 1900 (E. S. E., 18, p. 266). 



T\70 insects injurious to the strawberry, J. M. Stedman {Missouri Sta. Bid. 54, 

 l)p. 187-210, figs 5). — The strawberry false worm {Harpiphorits macidntus) develops 

 only 1 brood per year in Missouri. The larvse hatch out about the time the first 

 strawberry blossoms appear and remain on the plants until the berries are ri])e. 

 Descrijitive and l)iological notes are given on this species. The insect may be con- 

 trolled by thorough dusting with pyrethrum. This substance may be sprayed upon 

 the plants at any time, even when the fruit is ripe. It may be necessary to make 

 2 or 3 applications to control the pest. The larvae may also be destroyed by spraying
