160 EXPERIMENT STATION RECORD. 



flies, ants, and other insects which are injurious to clothing, furniture, or food, or 

 which annoy man otherwise. Proper remedies are suggested for the control of 

 these pests. 



Collecting' and preserving- insects, F. Sherman, Jr. (N. C. Dept. Agr. Ent. Circ. 

 15, pp. 14, figs. 9).— Brief directions are given regarding the necessary apparatus and 

 methods to be adopted in collecting and preserving various kinds of insects. 



Entomology in schools, H. S. Saunders (Canad. Ent., 37 (1905), No. 2, pp. 33, 

 34, pi. 1). — A brief account is presented of the classification of the insects with sug- 

 gestions as to how collections of insects may be made for use in teaching entomology 

 in schools. 



The colors of insects, A. U. Battley (East Kent $ci. and Nat. Hist. Soc. JRpt. and 

 Trans., 2. ser., 4 (1904), pp- 4-6).— Colors in insects are largely due to the unequal 

 refraction of the light or to actual pigments deposited in definite particles in the 

 integument. The significance of color in insects is briefly discussed. 



How do insects pass the winter? J. Fletcher ( Canad. Ent. ,37 (1905), No. 3, pp. 

 79-84). — Brief notes were given on the methods of hibernation observed in various 

 species of insects. 



Report of the entomologist, J. Fletcher ( Canada Expt. Farms Rpts. 1904, pp- 

 210-251, pis. 2). — During the season under report cereals were attacked by wire- 

 worms, cutworms, grasshoppers, Hessian fly, wheat-stem sawfly, grain aphis, and 

 wheat midge. 



Wireworms may be partly controlled by 2 plow'ings in autumn. The Criddle mix- 

 ture continues to give good results in combating grasshoppers. Locust fungus was 

 effective in a few instances only. There is apparently but one brood of Hessian fly 

 in western Canada. The pea weevil has appeared only in very small numbers for 

 the past 2 years. The cause of its disappearance is not known. It is recommended 

 that all seed peas be treated before sowing and that the crop be harvested as early as 

 possible. 



Notes are given on bollworm, Eriopeltis festucse, various cutworms, root maggots 

 on onions, cabbage, and radish, Nectarophora solanifolii on potatoes, Entomoscelis 

 adonidis on turnips, Pionea straminalis on cabbage, San Jose scale, plum aphis, plum 

 curculio, apple maggot, codling moth, and various pests of forest and shade trees. 



J. Fixter reports on the apiary. The best cellar temperature for the winter is 42 

 to 48° F. Colonies passed the winter well when the tops of the hives were replaced 

 with chaff cushions or propolis quilts. Successful wintering appears to depend on 

 uniformity of temperature and good ventilation. In a comparison of sugar sirup and 

 extracted honey colonies consumed during the winter on an average 62 lbs. 1 oz. of 

 the former and 62 lbs. 8 oz. of the latter. Notes are also given on methods of intro- 

 ducing queens. 



Common injurious and beneficial insects of Maryland, T. B. Svmons (Mary- 

 land Sta. Bui. 101, pp. 125-204, figs. 52). — The author presents a list of insects con- 

 tained in the entomological exhibit of the station and used at county fairs and farm- 

 ers' meetings throughout the State. The insects in the collection are classified in 

 general according as they affect orchards, grains, vegetables, household goods, etc. 

 Beneficial insects are also mentioned and brief directions given for the preparation 

 of insecticides. 



Miscellaneous cotton insects in Texas, E. D. Sanderson ( U. S. Dept. Agr., 

 Farmers' Bui. 223, pp. 24, figs. 29).— Biological, descriptive, and economic notes are 

 presented on a large number of cotton insects, including cutworms, plant lice, web- 

 worms, white-lined sphinx, grasshoppers, May beetles, CEcodoma fervens, Uranotes 

 melinus, leaf hoppers, plant bugs, etc. In controlling these cotton pests it is recom- 

 mended that weeds near cotton fields be destroyed and clean cultivation be adopted. 



The cotton bollworm, A. L. Quaintance and C. T. Brces ( U. S. Dept. Agr., Bur. 

 Ent. Bui. 50, pp. 155, pis. 25, figs. 27).— This constitutes an elaborate monograph of
