388 EXPERIMENT STATION RECORD. 



Experimental work with the peach aphis, W. W. Froggatt (Agr. Gaz. New 

 South Wales, 15 (1904), No. 7, pp. 608-612). — The occurrence and life history of 

 Aphis perskse-mger are described in some detail. Infested peach trees were sprayed 

 with lime-sulphur-salt wash containing 30 lbs. lime, 20 lbs. sulphur, and 15 lbs. of 

 salt per 60 gal. of water. It is recommended that this wash be applied to peach 

 trees in New South Wales during the month of July. The cold weather of winter 

 apparently has no effect in checking the propagation of this pest. A number of 

 parasitic insects wen- observed preying upon the peach aphis, and detailed descrip- 

 tive notes are presented on these species. 



The army worm in Australia, W. W. Froggatt \Agr. Gaz. New South Wales, 

 15 (1904), No. 4, pp. 827-831, figs. 2). — During the season of 1903-4 the long-continued 

 Australian drought was broken by a period of abundant rainfall. Vegetation grew 

 very luxuriantly and the large numbers of army worms which appeared showed that 

 the eggs of this species were capable of resisting excessive drought and unfavor- 

 able conditions. The approved methods of controlling this pest are described and 

 recommended. 



Report on Tortrix pilleriana, P. Marchal (Bui. Mens. Off. Renseignements Agr , 

 3 (1904), Feb., pp. 177-196). — This insect is considered the most serious pest of grapes 

 in France. It develops one generation per year. A detailed account is given of 3 

 general methods of procedure against the pest. The most effective method consists 

 in spraying the grape vines with water at a boiling temperature. Similar treatment 

 with superheated steam and spraying with various insecticides also proved fairly 

 satisfactory. The moths may be captured by means of lantern traps. The author 

 recommends the application of boiling water to grape vines during the period of 

 hibernation of the pests. 



The strawberry weevil, F. Sherman, Jr., and R. W. Collett (North Carolina 

 Dept. Agr., Ent. Circ. 12, pp. 8).— An account is given of the damage inflicted by this 

 pest on the strawberry industry, together with notes on the appearance, life history, 

 and habits of the insect. It was found by an examination of infested strawberry 

 fields that for a period of 2 weeks after the last picking of the season the insect could 

 be found in an adult, pupal, and larval condition. During this time, therefore, it is 

 possible to attack the pest most advantageously. A large number of remedies was 

 tried for this purpose. 



During the experiments reported by the authors air-slaked lime, Bordeaux mix- 

 ture and Paris green, carbolic acid and water, whale-oil soap in water, spirittine, and 

 other insecticides were sprayed upon infested strawberry plants. As a result of 

 these experiments it is believed that little hope can be entertained of any material 

 benefit from spraying. The best results will probably be secured through the plant- 

 ing of varieties with imperfect blossoms, the prompt mowing and burning of fields, 

 the destruction of rubbish along the edges of strawberry fields, and clean culture, 

 together with spraying with Bordeaux mixture and Paris green. The last-named 

 remedy is recommended not on account of its effect upon the weevil, which is very 

 slight, but because it has a beneficial effect in destroying leaf beetles and controlling 

 leaf rust. 



How to know butterflies, J. H. Comstock and Anna B. Comstock [New York: 

 l>. Appleton X- Co., 1904, pp. Nil + 311, pis. 45, figs. 49). — The authors have noted in 

 their class work in entomological courses that comparatively few persons are 

 acquainted with the names and habits of the common butterflies. This fact is attrib- 

 uted to the lack of suitable aids for beginners in this study. 



The present volume, therefore, is prepared for the purpose of furnishing brief 

 descriptions of species of butterflies with the best possible illustrations, and with 

 notes also on the more important facts in the life history of different species. A 

 general account is given of the relation of butterflies to other insects, the structure, 

 metamorphosis, and life history of butterflies. Each species included in the volume
