658 EXPERIMENT STATION EECORD. 



curculio {Orthorrhinus kluggi), which has in recent years caused considerable 

 loss to vineyardists, is said to have commenced to attack roses. 



The Anthonoinus of the raspberry and strawberry (Anthonomus rubi) 

 {Jour. Bd. Agr. [London^, 19 (1912), No. 5, pp. 394-^96).— A brief account of 

 this weevil, which is chiefly an enemy to plants of the genus Rubus. In Europe 

 it is best known because of its attacks uix)n the raspberry, but in England of 

 late it has been a serious enemy to the strawberry. 



Preliminary report on the picudo of cotton in Peru, C. H. T. Townsend 

 {Jour. Econ. Ent., 6 {1913), No. 3, pp. 303-312).— This paper relates to studies 

 of the Peruvian cotton square-weevil {Anthonomus vesUtus), an account of 

 which has been previously noted (E. S. R., 28, p. 161). The present paper deals 

 with its origin, discovery, and occurrence; response to climatic conditions; 

 parasites and predaceous enemies; cultural control measures; longevity and 

 period of inactivity ; capacity for damage ; and work for the future. 



Observations on the egg parasites of Datana integerrima, H. M. Russell 

 {Proc. Ent. Soc. Wash., 15 {1913), No. 2, pp. 91-97) .—This is a report of obser- 

 vations made of the black walnut caterpillar at Orlando, Fla., during 1907 and 

 1908. Four species of parasites, namely, Trichogramma minvJum, Telenomus 

 sphingis, Baryscapus sp., and Ooencyrtus sp., were reared from the eggs of 

 D. integerrima in September and October, 1907. From 10,926 eggs collected in 

 September and October, 1907, 3,924 larvie hatched, 6,365 parasites were reared, 

 and 637 eggs remained unhatched. Telenomus sphingis was the most abundant 

 of the parasites. 



Habrobracon hebetor, a confederate in the fight against the Mediterranean 

 fiour moth, J. Buchwald and E. Berliner {Ztschr.Gesam. Getreidew., 2 {1910), 

 No. 1, pp. l-If, pi. 1). — A brief discussion of this braconid parasite, which has 

 been found by the author to occur in Germany. It has also been recorded from 

 England, France, Australia, and this country. 



Some observations on the habits and reproduction of Habrobracon hebetor, 

 the Mediterranean flour moth parasite, E. Beelineb {Ztschr. Gesam. Getreidew., 

 3 {1911), No. 11, pp. 2Jf5-248). — Brief notes on the biology of this parasite. 



Some methods of handling minute hymenopterous parasites, T. E. Hol- 

 LOWAY {Jour. Econ. Ent., 6 {1913), No. //, pp. 341-34//). — The author describes 

 the methods which he has successfully employed in rearing and shipping the 

 egg parasites Trichogrannna minutum and Telenomus sp., probably heliothidis. 



Report of the assistant entomologist, E.G. Cotton {Tennessee Sta. Rpt. 1911, 

 pp. 182, IBS). — This report consists largely of a brief statement of the work with 

 the cattle tick {Margaropus annulatus) . 



In pathogenicity tests but slight attacks of Texas fever could be produced 

 during the colder season of the year by applying seed ticks reared from eggs 

 laid by ticks which had become engorged on immune young stock. Symptoms 

 of Texas fever appeared on the eleventh day in 2 aged cows upon which seed 

 ticks from adults engorged on immune cattle at Baton Rouge, La., had been 

 placed. On the thirteenth day 200 cc. of trypanblue was injected into one of 

 the cows and repeated after a short interval. On the fourteenth day 200 cc. 

 of trypanblue was injected into the second cow. Since the first cow died on 

 the sixteenth day and the second on the eighteenth day, it appears that the 

 drug can not be depended upon to cure this disease. 



Report of the assistant entomologist, E. C. Cotton ( Tennessee Sta. Rpt. 1912, 

 pp. 65, 66). — This report consists in large part of a description of a rearrange- 

 ment made of the temperature control plant, an account of which has been 

 previously noted (E. S. R.. 23, p. 657). 



Rocky Mountain spotted (or tick) fever. — Sheep grazing as a possible 

 means of'ccntrolling the wood tick (Dermacentor andersoni) in the Bitter
