5V)4 EXPERIMENT STATION RECORD. 



beetles were received from tlu- Division of Entoiii<ilo<ry<>f this Dcitartiucnt, l)ut tlicir 

 value in Delaware has not yet been deterniined. 



In controlling the strawberry root louse the best results were obtained l)y ))Uiiiing 

 over infested patches and by fumigating with hydrocyanic-acid gas or dii)i)ing in 

 tobacco water. Whale-oil soap and kerosene emulsion injured a large number of 

 the plants which weredii)iK'd into tlu'se solutions. Notes are also i)resented on the 

 jHTiodical cicada, harlequin cabbage l)Ug, white-marked tussock-moth, fall web- 

 worm, strawberry weevil, a])pl('-tree tent caterjiillar, ])lum cnrculio, etc.

 discussed mention may be made of the following: Crane flies, frit fly, pea weevil, 

 cabbage-leaf maggot, flea-beetles, cabbage butterfly, carrot fly, tarnished plant bug,

First report on economic zoology, F. V. Theobald (London: British Mus. Nat. 

 //^s^, 1903, pp. XXXIY^192, figs. IS). — This volume includes a large number of mis- 

 cellaneous articles on economic zoology and is intended for iise by the Board of Agri- 

 culture of London. The introduction was prepared by E. R. Lankester and contains 

 a classification of animals into groups, from the point of view of economic entomol- 

 ogy. The various ways in which animals affect man are mentioned, with examples 

 of species mider each group. 



A large number of miscellaneous insects and other noxious animals are discussed 

 under groups according as they are injurious to field crops, horticulture, trees, 

 domestic animals, household materials, etc. Copies are also given of reports to for- 

 eign and colonial offices on the subjects of tsetse fiy, white ants, locust plagues, etc., 

 and a list is presented of North African locusts and white ants. 



Hessian fly reared in the laboratory, F. L. Washburn [Canad. Ent., 35 {1903), 

 No. 11, J). 316) . — The author presents data obtained from breeding experiments with 

 the Hessian fly in the laboratory and also from observations in the field. The possi- 

 bility of a second brood of Hessian fly is suggested by these observations. 



Remigia latipes, A. Hempel {Bol. Agr. Sclo Paido, 4- ser., 1903, No. 7, 

 pp. 314-320. ) — The caterpillars of this species are injurious to corn, millet, and other 

 cultivated plants. Notes are given on the appearance of this insect in its different 

 stages, on the means of distribution, natural enemies, and artificial insecticide 

 treatment. 



Insect and fungous enemies of the peach, plum, cherry, fi.g, and persim- 

 mon, F. Sherman, Jr. {North Carolina Sta. Bid. 186, jyp- 5-22, figi^. 7). — Notes on

 {Connecticut State Sta. Bid. 144, pp- 26, pAs. 3). — During the season of 1903 spraying 

 experiments were made on about 11,500 trees, including peach, pear, and apple. 

 The insecticides used were lime, sulphur, and salt; lime, sulphur, and copper sul- 

 phate; lime and sulphur; lime and potassium sulphid; whitewash; strong Bordeaux 

 mixture; and a 25 per cent mechanical mixture of crude oil, all being applied to 

 dormant trees, while kerosene soap emulsion was used upon growing trees.
