890 EXPERIMENT STATION RECORD. 



Injurious insects of 1904, F. L. Washburn (Minnesota Sta. Bui. 88, pp. 13-197, 

 pis. 2,fig8. //\ v ). — The material of this bulletin has already been abstracted from 

 another source (see above). 



The insect record for 1903, C. M. Weed (New Hampshire Sta. Bui. 115, pp. 172- 

 176; Rpt. 1904, pp. 259-264). — Attention is called to the distribution of the brown- 

 tail moth in New Hampshire. Brief notes are also presented on a number of fruit 

 and garden insects, including oyster-shell bark-louse, apple aphis, eankerworm, tent 

 caterpillar, plum curculio, cabbage-root maggot, squash bugs, etc. 



The increase and spread of injurious insects in North Carolina, 1>. L.White 

 (Agr. K<h (cation, 6 (1904), No. 5, pp. 75-77). — Brief notes are given on the condi- 

 tions which favor the general spread of insect pests, with especial reference to the 

 Hessian fly and San Jose scale. 



Insects pests and spraying, F. Sherman, Jr. (Bui. North Carolina State Bd. 

 Agr., 25 (1904), No. 10, pp. 13-18). — Brief notes are given on the habits, life history, 

 and means of combating a large number of injurious insects. Directions were also 

 presented for spraying apple trees, potatoes, grapes, and other economic plants. 



The monthly bulletin of the division of zoology, H. A. Surface (Pennsylvania 

 State Dept. Agr., Mo. Bui. Dir. Xool., 2 (1904), No. 7, pp. 195-224).— Brief notes are 

 given on practical measures for control of injurious insects in November, with espe- 

 cial reference to the use of lime-sulphur compounds and other insecticides in the 

 control of San Jose scale. 



Destroying insects and fungus diseases, ( ). M. Morris ( Oklahoma Sta. Bui. 64, 

 p]>. 19). — The most common insect pests in Oklahoma are stated as being codling 

 moth, tent caterpillars, plum curculio, grape leaf hopper, and grape worm, while the 

 most injurious fungus diseases are apple seal), bitter rot, apple rust, brown rot, 

 blackberry rust, black rot, and anthracnose of grapes. 



A number of experiments were made in spraying for the control of these insects 

 and fungus diseases. In spraying for codling moth various arsenicals were used, 

 including Paris green, London purple, and arsenate of lead. All of these are effect- 

 ive, but the combination of Bordeaux mixture and Paris green has the advantage of 

 destroying the codling moth and preventing fungus diseases. The spraying should 

 be applied as soon as the blossoms fall and should be repeated every 2 weeks for 4 

 times. Two sprayings appeared not to be effective in controlling the codling moth. 



A test of dust spraying seemed to show little promise for the use of this method in 

 Oklahoma. When Paris green and Bordeaux mixture were used about 80 per cent 

 of the fruit on treated trees was free from infestation. Notes are given on the 

 methods of control of other insect pests and fungus diseases, and formulas are pre- 

 sented for insecticides and fungicides. 



Entomological investigations in Jylland in 1903, N. Fritz (Hedeselsk. 

 Tidsskr., 1904, No. 11, pp. 279-281). — Brief notes are given on the habits and injuri- 

 ous attacks of Retinia buoliana, Tomieus bidens, and other injurious insects. 



Report of the entomologist, W. W. Froggatt (Agr. Gaz. New South Wales, 15 

 (1904), No. 11, pp. 1031-1034)- — Brief economic and biological notes are presented 

 on the army worm, peach aphis, fig insects, pear slug, bot fly, phylloxera, and the 

 inspection of poultry lor insect pests. 



Economic entomolgy, H. Tryon ( Queensland Dept. Agr. Rpt. 1903-4, pp. 67-69). — 

 Brief notes are presented on the insect enemies of deciduous fruit trees, citrus fruits, 

 mango, grapevine, strawberry, cotton, garden crops, cereals, sugar cane, etc. A 

 short account is also given of the importation and distribution of injurious species, 

 together with an account of the value of insectivorous birds and the danger of impor- 

 tation of phylloxera. 



The entomological section, C. B. Simpson (Transvaal Agr. Jour., 2(1904), No. 8, 

 pp. 603, 604). — A short account is given of fumigation tents, locust destruction, bee- 

 keeping, and insects injurious to cabbage and corn.
