58 EXPEEIMENT STATION RECOED. [Vol.35 



Rice borers in Java, K. W. Dammerman {Dept. Landb., Nijv. en Handel 

 {Dutch East Indies^, Meded. Lab. Plantenziekten No. 16 {1915), pp. 71, pis. 7, 

 figs. 2). — Five species of rice borers are known at the present time in Java, 

 namely, Schoenobius bipiinctifer, ^cirpophaga scricea, two species of Cliilo, and 

 Sesamia kif evens. S. bipunctifer, which occurs throughout Java, and S. sericea, 

 found principally along the north coast and the more common there of the two, 

 are the two most important. Of the several parasites attacking rice borers, 

 Trichogrammatoidea nana alone may destroy as high as 60 per cent of the eggs. 

 The destruction of the borers which remain in the stubble after harvest by deep 

 plowing is the most effective control measure. 



A note on the western twig borer, H. S. Smith (Mo. Bui. Com. Hort. Cat., 

 4 (1915), No. 12, pp. 572, 573, fig. 1). — Polycaon confertus has become a pest of 

 considerable importance in California. 



The wheat straw worm (Isosoma grande), R. W. Doane (Mo. Bui. Com. 

 Hort. Cal., 5 (1916), No. 2, pp. 69-72, figs. 2). — This pest has been found to be 

 the source of considerable injury in northern California, actual counts of hun- 

 dreds of wheat stems showing 84 per cent to be infested with one or more larvse 

 or pupfe of this insect. 



Hen fleas (Xestopsylla gallinacea), J. P. Illingworth (Haivaii. Forester and 

 Agr., 12 (1915), No. 5, pp. 130-132). — An account of the hosts, distribution and 

 life history, and control measures for the hen flea, which appears to be a recent 

 arrival in Hawaii, not having been collected by entomologists prior to 1913. 



Notes on the habits and control of the chicken flea (Echidnophag'a galli- 

 nacea), J. F. Illingworth (Jour. Econ. Ent., 8 (1915), No. 5, pp. Jf92-495). — A 

 report of studies, a brief account of which has been noted above. 



Observations on the preoviposition, ovlposition, and incubation periods of 

 Dermacentor nitens in Panama, L. H. Dunn (Ent. News, 26 (1915), No. 5, 

 pp. 214-219). — A report of biological studies of the tropical horse tick. 



Sarcophaga fuscicauda, an intestinal parasite of man, A. Eysell (Arch. 

 Schiffs u. Tropen Hyg., 19 (1915), No. 1, pp. 2-7, figs. 4)- — Descriptions are 

 given of the larva, pupa, and adult of S. fuscicauda taken at Tsingtau. 



rOODS— HUMAN NUTRITION. 



The milling and baking quality and chemical composition of wheat and 

 flour as influenced by different methods of handling and storing, heat and 

 moisture, [and] germination, C. O. Swanson, L. A. Fitz, and Leila Dunton 

 (Kansas Sta. Tech. Bui. 1 (1916), pp. 83, pis. 22).— The object of this investiga- 

 tion was to determine the effect of different methods of harvesting, stacking, 

 and storing wheat ; the aging effect of tempering with moistui-e and heat ; and 

 the effect of germination of new wheat on the milling quality of the wheat, the 

 baking quality of the flour, and the chemical composition of the wheat and flour. 



" All the tests were made on the same original lot of wheat. A 10-acre fleld 

 of fairly uniform character w^as obtained. One acre was cut at the beginning 

 of the hard-dough stage, one when the wheat was dead ripe, and the rest when 

 the wheat was in prime condition. As soon as the wheat was dry, a few 

 bushels were thrashed from the early and from the late cuttings, and 35 bu. 

 from that cut in prime condition. Samples of the wheat from the three cut- 

 tings were taken to the lalioratory for immediate milling, baking, and cliemical 

 tests. The wheat cut in prime condition was used for the study of the effect of 

 germination, the process of sweating in the bin, and for treatments with heat 

 and water. The larger part of the 10-acre field was stacked. One acre was 

 allowed to stand in the shock."
