258 EXPERIMENT STATION RECORD. 



Lysiphlcbus triiici, the Hessian fly by Polygnotus hiemalis, the army worm 

 (Ilcliophila uniimnctu) by Winthemia quadripustulata, and grasshoppers by 

 parasitic flies as Melanoplus differentiaUs by Sarcophaga georginu. The per- 

 petaal benefits derived from parasites and their artificial introduction and diffu- 

 sion are related. 



Fruit fly parasites, G. C. Baker (Jour. Dept. Agr. West. Aust., 16 il!)08). 

 No. /, pp. 27, 2S, pi. 1). — It is stated that after three unsuccessful attempts to 

 establish in Western Australia a parasite of the fruit fly, success has at last 

 been achieved, one generation of parasites having already been bred there. 

 The attempt will be made to breed other parasites to assist in controlling fruit 

 flies. 



Anatomy, biology, and pathogenicity of Ixodes reduvius, V. E. Vorontzov 

 (Anatomiya, BvAogiya, i Patogennost Kic-slitslici vida Ixodes reduvius. St. 

 Petersburg: Govt., 1907, pp. Jtl, pis. 3). — The author discusses in detail the 

 anatomy and biology of Ixodes reduvius with particular reference to its agency 

 in carrying hemoglobinuria of cattle. This disease has definitely been shown 

 to depend upon the ticks for its transmission. The eggs of /. reduvius may 

 retain their vitality under water in swampy areas from fall until spring. 



The tsetse fly in India, H. M. Lefroy (Agr. Jour. India, 2 {1907), No. If, 

 pp. 374-376). — On account of the importance of the tsetse fly as a carrier of 

 animal and human diseases an investigation was made to determine whether 

 this fly occurs in India. According to the evidence thus far accumulated it does 

 not appear to be found in India, and in the author's opinion the likelihood of 

 accidental importation is quite remote. 



Apiculture, E. Chavez (Apicultura. Mexico: Govt., 1007, pp. 12). — This i)am- 

 l)hlet contains an account of the conference of apiculture held at the agricul- 

 tural and industrial fair at San Luis Potosi. The chief subjects discussed were 

 the necessity of studying local bee plants and the influence of insects, particu- 

 larly bees, on the fertilization of plants. 



Bee diseases in Massachusetts, B. N. Gates ( U. S. Dept. Agr., Bur. Ent. 

 Bui. 75, pt. 3, pp. 23-32, map 1). — Both American and European foul l)rood 

 have been found to exist in practically every quarter of JNIassachusetts and 

 Connecticut as well as in the other New England States. There seems to be 

 undeniable proof that their introduction is not recent, and that there are fewer 

 bees kept on the farms than there were 50 years ago seems to be due in part 

 to the effect of these diseases. A map is given showing the distribution of the 

 two diseases in Massachusetts and the possible sources of infection from neigh- 

 boring States. 



FOODS— HUMAN NUTRITION. 



Changes taking place in chickens in cold storage, Mary E. Penningtott 

 iU. S. Dept. Agr. Yearbook 1907 . pp. 197-206, pis. 7). — A summary and discus- 

 sion of data obtained in a study of the appearance and characteristics of 

 freshly killed fowls and poultry stored respectively ten months, two years, and 

 three years. 



In the stored poultry changes in appearance and character were noticeable, 

 being much greater in the samples stored for a long period than in those in 

 storage for a shorter time. In the case of chickens in storage for three years, 

 changes in the texture and color of both muscles and fat were striking. There 

 was a very considerable drying out, particularly in the muscles of the upper 

 breast and between the muscles the bands of fat were shrunken and of a deep 

 brown-orange color. " No feature of the entire chicken was more striking by 

 comparison with the fresh fowl than this change in the color of the fat.
