The plant lice of sugar cane in Java, L. Zehxtxer (Jfcv/cr?. Proefdat. Snlbrrief 

 WeM Javd, 1901, No. 5,1, pp. 22, ph. 2). — The author gives descriptive, biological, 

 and economical notes on Aphis sacchari, A. adustu, and Tetraneura lucifuga. 



Insect enemies to fruit, and their remedies, W. B. Smith {Proc. Columbus 

 Ilort. Soi-., Id (1901), Xo. 1, pp. .'>8-G2). — Brief notes on the habits and life history 

 of codling moth, apple-tree borer, apple-tree tent cateri^illar, San Jose scale, plum 

 curi'uUo, peach borer, currant aphis, and other injurious insects. The approved 

 i'cnit'(Hes are mentioned in the discussion of each insect. 



Insects injurious to fruit, A. H. Sxyder {Proc. ('olnmhus Hort. Soc, V, [1901), 

 No. 1, pp. 34--')S). — The author presents brief notes on the liabits, life history, and 

 means of combating codling moth, round-headed apple-tree borer, apple-tree tent 

 caterpillar, plum curculio, rose chafer, s^jring and fall cankerworm, May beetle, and 

 other injurious insects. 



Rhynchites minutus an enemy of the strawberry, J. Ritzema Bos {TijdscJir. 

 I'lantenziekten, 7 {1901), No. 2, pp. 39-41). — This species is reported as having caused 

 injury to strawberries since 1897. The stems, which are attacked, wilt, and the leaves 

 die. No successful remedies have been devised for combating this species. 



Combating the root louse of gooseberry and currant by injections of ben- 

 zine in the ground, J. Ritzem.\ Bos {Tijchchr. Plantenzieklen, 7 {1901), No. 2, pp. 

 37-SS). — Hchlzonenni gromularhe was not known as an injurious insect in Holland 

 until within the past few years, when it has become quite important as an enemy of 

 the gooseberry and currant. Experiments were made in 1900 to determine methods 

 for destroying this insect. The use of either carbon bisulphid or benzine proved to 

 be very effective when these substances were injected into the ground about infested 

 bushes. All of the root lice were destroyed by a single application. 



Report of the State entomologist, J. B. Smith {New .Jersey Stale Bd. Agr. Rpt. 

 1901, pp. 237-242). — The greater part of the work of the State entomologist has been 

 done in i-ombating the San Jose scale. Notes are given on the practical working of 

 quarantine laws and on the use of certificates of inspection. It is argued that San 

 Jose scale can not be exterminated by artificial means but may be held in check by 

 tlie use of appropriate remedies. It is stated that, as a rule, the owners of nursery 

 stock and orchards have readily responded to directions given concerning treatment 

 for injurious insect pests and that no resort to force lias l)ecome necessary. 



Report on the inspection of Roanoke County for the San Jose scale, W. B. 

 Alwood ( Virginia Sla. Spec. Bui., 1901, Dec. 10, pp. 37, map 1). — In this report the 

 author gives a list of localities in Roanoke County infested with the San Jose scale. 

 Tile total number of infested localities is reported as 636; the total number of infested 

 trees as 4,144, and the nundoer of trees in the infested orchards, 74,588. 



Three common orchard scales, II. T. Ferxald {Masxacliusetts Stcde Bd. Agr. Rpt. 

 1901, pp. 353-363, pi. 1, figs. 2). — Brief descrii)tive and biological notes are given on 

 oyster-shell bark-louse, scurfy scale, and San Jose scale. The food plants of these 

 scale insects are mentioned and notes given on their distribution, natural enemies, 

 and the treatment which is most effective against them. The insecticide treatments 

 recommended include fumigation and spraying with kerosene, crude petroleum, and 

 whale-oil soaj), together with pruning of infested trees before spraying. 



Treatment for San Jose scale, J. H. Stewart {West Virginia Sta. Bui. 78, pp. 

 213-230, figs. 6). — In this bulletin the author gives a popular account of the means 

 of combating the San Jose scale, the conditions which are favorable for successful 

 treatment, brief notes on the most effective insecticide treatments, and on spraying 

 apparatus. The insecticide treatments which are recommended for destroying the 

 San Jo.se scale -include mechanical mixtures of kerosene and water, kerosene con- 

 taining from 5 to 10 per cent of vaseline, kerosene mixed with vaseline and paraffin, 

 crude oils, whale-oil soap, kerosene emulsion, fumigation, and the destruction of

 by the legislature of West Virginia on the subject of nursery inspection and the 

 prevention of injury from insect pests and fungus diseases.
