262 EXPERIMENT STATION RECORD. 



(Telraniehus sp.), pear leaf blister mites (Phytoptuspyri), coleotbrips, cabbage worms 

 (Pieris rapes), cabbage lice (Aphis brassicw), rose leaf bopper (Typhlocyba rosw), buf- 

 falo tree boppers (Ceresa bubalus), Howard's scale (Aspidiotus boivardi), and several 

 other insects not named scientifically. Tbe apple maggot and the striped cucumber 

 beetle were reported to tbe station for the first time during the summer of 1896. 



Entomological notes, W. W. Froggatt (Agr. Gaz. N. S. Wales, 8 (1897), iVo. 2, 

 pp. 99-104, figs. 6). — On the currant clear wing moth (Sesia tipuliformis), vine moth 

 bug (Arma sibellanbergi), grape destroying beetle (Monolepta diversa), cherry bug 

 (Peltophora picta), and peach moth (Conogethes punotiferalis) . 



Injurious insects and fungi (Jour. Bd. Agr. [London'], 4 (1897), I, pp. 46-57, 

 jig, 2). — A popular account of the injuries of the branded fir beetle (Pissodes notatus) 

 and gypsy moth (Porthetria dispar) in Massachusetts, and the peach leaf disease 

 known as curl, caused by Exoacus deformans. For tbe latter, spraying with a Bor- 

 deaux mixture made of 3 lbs. of copper sulphate and 3 lbs. of lime in 50 gal. of 

 water is recommended. 



Experiments with woolly aphis or American blight (Agr. Gaz. N. S. Wales, 

 8 (1897), No. 2, pp. 120, 121). — Successful results were obtained with kerosene 

 applied at the base of the tree, and with a band of wool soaked in castor oil about 

 the tree trunk to prevent insects from ascending. 



New codling moth spray (California Fruit Grower, 20 (1897), No. 18, p. 1). — 

 Recommends soda-arsenic-lime mixture proposed by R. C. Kedzie, which can be 

 made at the small expense of 4 cts per barrel. Two pounds of arsenic boiled with 

 7 lbs. of sal soda for 15 minutes in 2 gal. of water and 2 lbs. of slacked lime added. 

 This may be diluted to make 800 gal. 



The Gonin injector, J. Ritzema Bos (Tijdschr. Plantenziekten, 2 (1896), pp. 28-43, 

 figs. 6). — Describes an apparatus for injecting benzin, carbon bisulphid, etc., into the 

 soil to destroy insects. 



A parasite of hemipterous eggs, T. D. A. CocKerell (Canadian Ent., 29 (1897), 

 No. 2, pp. 25, 26). — A description of Hadronotus mesilla' n. sp., bred at Las Cruces, New 

 Mexico, from the eggs of a hemipteron. 



On combating the phylloxera in Russia, B. Vitmer (Selsk. Ehoz. Lyesov., 182 

 (1896), pp. 609-627). 



The struggle against the grapevine leaf beetle, P. Gervais (Prog. Agr. et Yit., 

 14 (1897), No. 15, pp. 442-446). — The adult and the larval state are considered. 

 Against the insect in the former state a mixture of pyrethrum solution (1 to li kg. 

 of the powder to 500 liters of water) with a solution of copper acetate made in the 

 same proportions is considered the best of 3 mixtures mentioned, the other 2 

 being a solution of pyrethrum and soap, and a solution of pyrethrum, soap, and cop- 

 per acetate. Against the larva a mixture of pyrethrum and suljmur in the propor- 

 tions of 1 of the former to 3 of the latter is not thought as good as a mixture of 

 pyrethrum and sulphosteatite. The proportions employed in this mixture were 15 

 parts of pyrethrum to 85 parts of the sulphosteatite, and was applied at the maxi- 

 mum rate of 30 kg. per hectare. 



Spray pumps and spraying, W. Paddock (New York State Sta. Bui. 121, pp. 197- 

 219, figs. 15). — An attempt is made to fill the want of elementary instruction in this 

 subject. The reader is told wheu to spray, when not to spray, how to select a pump, 

 how to work intelligently, how to prepare Paris green, kerosene, and copper-sulphate 

 solutions, the Bordeaux mixture, and in the case of the latter how to weigh the 

 lime and apply the potassium ferro-cyanid test. The greater portion of the bulletin 

 is devoted to brief descriptions of spraying apparatus, including the pumps known 

 as the Eclipse, Pomona, Casewell, Advance, Empire Queen, Geiger, Defender, bucket 

 pumps, knapsack sprayers, the Lightning Potato Bug Killer, steam sprayers, horse- 

 power sprayers, and several home-made conveniences and nozzles. 



Spraying mixtures and their application, F. H. Hall (New York State Sta. Bui. 

 121, popular ed., pp. 6). — A popular summary of Bulletin 121 of the station (E. S. H., 

 9, p. 262).
