266 EXPERIMENT STATION RECORD. 



when applied to the trunk. The life history of the bean4eaf beetle was studied, and 

 arsenate of lead tested without very promising results. Notes are also presented on 

 Southern corn root worm, Ligyrus rugiceps, boll worm, an undescribed snout beetle, 

 false chinch bug, San Jose scale, mosquitoes, Pegomyia fusiceps, and Dynastes tityrus. 



Second annual report of the State entomologist, R. A. Cooley (Montana Sla. 

 Bui. 55, pp. 125-180, pis. 3, figs. 25) . — Phenacoccus dearnessi was found on apple trees 

 and closely resembling woolly aphis. It occurs also on the elm and may be con- 

 trolled with soap or kerosene washes. 



Otiorhynchus ovatus greatly injured strawberry plants near Missoula. The nature 

 of the attack is discussed and the insect is described in all its stages. Dipping the 

 plants in arsenate of lead was found to render the plants immune for about 2 weeks. 

 The best remedy is probably to be sought in a proper rotation of crops. Remedies 

 for the bud moth were studied by B. J. Jones, who found that the larvae feed entirely 

 on the leaves after the first spring attack on the opening buds. Trees should be 

 sprayed with arsenate of lead before the buds open and later as required. 



Brief statements are also made regarding other insect pests, such as peach-tree 

 borer, apple-tree borers, bronze apple-tree beetle, apple-twig borer, fruit-tree bark- 

 beetle, peach-twig borer, San Jose scale, woolly aphis, various scale insects, codling 

 moth, plum curculio, etc. 



Report of the government entomologist for the half year ended June 30, 

 1904, C. P. Louxsbury (Cape Good Hope Dept. Agr., Ept. Govt. Ent. 1904, pp. 35, 

 pi. 1). — This report contains an account of the routine w T ork of the entomologist, 

 publications, plant import regulations, nursery legislation, ticks, African coast fever, 

 heartwater, and locusts. 



It was found that when the brown tick feeds on affected cattle only during the 

 nymphal stage it does not carry infection. The nymphal bont tick carries heart- 

 water, as demonstrated in experiments with goats. Cattle w T ere shown to be sus- 

 ceptible to the disease. Horses are immune. Rhipicepfialus decoloratus is not patho- 

 genic. Persian sheep are highly susceptible to heartw T ater, but have very light 

 attacks and are thereafter perfectly immune. 



C. W. Mally also presents a report on insects affecting corn and fruit, especially on 

 Sesamia fusca and Ceratitis capitata. 



Annual report for 1904 of the zoologist, C. Warburtox (Jour. Boy. Agr. Soc. 

 England, 65 (1904), pp. 273-287, figs. 4)- — During the year under report peas were 

 greatly injured by Diplosis pisi and Grapholitha pisana. When peas are infested with 

 these pests it is desirable that sound pods be removed at once and that infested plants 

 be destroyed. 



The adoption of a suitable system of rotation will largely control the insects. Notes 

 are also given on phylloxera and other plant lice, with an account of their biological 

 relations, and special notes on corn aphis, pea aphis, hop aphis, etc. A number of 

 mites proved injurious during the year under report, and ferns were considerably 

 damaged by a new species of mite described under the name Tarsonemus chironiee. 



The Hessian fly {Ed. Agr. and Fisheries [London], Leaflet 125, pp. 3, figs. 7) 

 This pest is described, with notes on its food plants, life history, and means of pn 

 vention. It is recommended that infested stubble be burned and a suitable rotation 

 of crops adopted. 



Julus impressus in the corn field, F. M. Webster (Cariad. Ent., 37 (1905),. 

 No. 5, p. 172). — The author observed what appeared to be this species infesting unripe 

 ears of corn in Illinois and Minnesota, It may prove, however, that some other 

 species was concerned in the production of the injury. 



The wormy apple, A. L. Melaxder ( Washington Sta.Bul. 68, pp. 16, figs. 6).— A 

 popular account of the habits and life history of the codling moth is given, together 

 with notes on the losses due to this insect. Suggestions are also made regarding
