ENTOMOLOGY. 1089 



The results oljtained were very satisfactorj' and furnished strong evidence in favor 

 of spraying with Bordeaux mixture to prevent black rot. In one instance a saving 

 of 33J per cent was brought about by spraying. 



Dust or powder sprays, J. Craig {New York Cornell Sta. Bui. 316, pp. 111-117). — 

 A number of experiments were carried out for the purpose of determining the rela- 

 tive value and effectiveness of dry fungicides. It was found that the labor and 

 expense of applying dust sprays were less than in the case of liquid sprays, but that 

 more applications were required. The brown rot of peach and plum is apparently 

 not cortrolled by fungicides applied in the dry form. It is recommended that dust 

 sprays be applied in the early morning, late afternoon, or in damp weather. In gen- 

 eral, it ajjpears that there is no sufficient reason for adopting the dry spray in place 

 of the wet form on grounds sufficiently level to admit the manipulation of a spraying 

 outfit. 



ENTOMOLOGY. 



Proceedings of the Entomological Society of Washington {Proc. Ent. Soc. 

 Washington, 6 {1904), No. 3, pp. 61-126, fig. 1). — This number contains an account of 

 the meetings of the Entomological Society of Washington from January 14 to March 

 10, 1904. A considerable number of entomological papers were read, some of which 

 had an economic bearing and will be noted in this connection. 



A brief synopsis of honey bees by W. H. Ashmead divides these insects into two 

 genera, Megapis and Apis. The first genus includes only M. dorsata and M. zonata, 

 while to the genus Apia 7 species are referred. 



E. A. Schwarz describes a new coccinellid enemy of the San Jose scale. A new 

 species of ladybug beetle is reported as occurring abundantly on fruit trees infested 

 with San Jose scale and is efficient in controlling the scale. The species is described 

 under the name of Pseudoiveisea suturalis. 



F. Benton discusses the specific name of the common honeybee, concluding that 

 it should be Aj^is mellifera rather than A. meUifica. 



Report of the entomologist, C. French {.Tour. Dept. Agr. Victoria, 2 {1903), 

 No. 3, pp. 245-349). — During the year under report the author carried on a number 

 of experiments with grasshopper fungus, spraying for San Jose scale with lime- 

 sulphur-salt wash, fumigation, and along other lines. Notes are also given on the 

 mspection of orchards and nurseries and on injurious birds, of which the English 

 starling appears to be the most important. 



The cause and control of insect depredations, E. P. Felt {Proc. Soc. Prom. 

 Agr. ScL, 1904, pp. 73-83). — The author discusses the biological factors which are 

 concerned in determining the prevalence of insect pests. In discussing general 

 methods of controlling insects reference is made to clean culture, rotation of crops, 

 the encouragement of natural enemies of insects, and the application of various insecti- 

 cide treatments. 



Insects injurious to plants, F. Corboz {Chron. Agr. Canton Vaud, 17 {1904), No. 

 9, pp. 297-307, figs. 4)- — Attention is called to the desirability of protecting insectivo- 

 rous birds on account of their help in controlling various insects. Brief notes are 

 given on the depredations of Melolontha vulgaris, fruit-tree bark-beetle, and other 

 insects injurious to trees. 



Insects injurious to fruits in Michigan, R. H. Pettit {Michigan Sta. Spec. Bui. 

 24, pp. 79, figs. 70). — This bulletin is issued as the first of a series on insects affecting 

 various classes of crops. The habits, life history, and means of combating most 

 common species of insects which affect different fruit trees are discussed in consid- 

 erable detail. The insect pests are classified according to the fruit trees which they 

 injure most, and according to the part of the tree or fruit affected. 



Injurious insects of 1903, F. L. Washburn {Minnesota Sta. Bui. 84, pp. VIH^- 

 184, pi- 1, figs. 119). — This has already been noted as the annual rejiort of the author 

 as State entomologist (E. S. R., 15, p. 784).
