758 EXPERIMENT STATION RECORD. 



The genus Eutettix, with special reference to E. tenella, the beet leaf 

 hopper, E. D. Ball {Ohio State T'liiv., ContriJj. Dcpt. ZooJ. and Eiit., No. 27, 

 pp. 27-9.'i. pis. .'/). — Sugar-beet leaves are sometimes affected in Utah with a 

 peculiar condition Ivuovvn as curly leaf or blight. Tliis lias been found to be due 

 to the attacks of Eutettiw tenella and other species of this genus. On the basis 

 of biological and anatomical characters the author has proposed a systematic 

 revision of this genus. A great variety of material was examined representing 

 the species of the genus as found in various parts of the United States. De- 

 tailed technical descriptions are given of all these species, together with analyt- 

 ical tables to assist in their identification. 



In the year 100.5 E. tene'lu is believed to have caused damage to sugar beets 

 to the extent of $500,000 inUtah. In 190(3 the leaf hoppers were not so nu- 

 merous. All species of this genus thrive best in hot. dry situations, and it has 

 lieen found that they may be partly controlled l>y thorough and frequent 

 irrigation. 



A myriapod injurious to garden crops, Dublesel and J. Beziat {Jardin, 

 21 {1907), No. 20, p. 2Jf7). — A myriapod belonging to the species Blaniulus 

 fjiittulatus has been found to cause serious injury to peas, beans, potatoes, sugar 

 beets, etc., in gardens. The main damage is done by attacking the seed in the 

 ground. 



Cutworms, H. T. Fernald {Massachusetts »S7«. Cire. 2, pp. 2). — Brief notes 

 are given on the life history of cutworms. These pests may be effectively con- 

 trolled by clean culture and the use of poisoned baits made of clover or bi'an 

 and some arsenical. 



Wireworms, C, E, HooD {Massachusetts St a. Circ. J/, pp. 2), — In the control 

 of wireworms clean cultivation is reconnnended combined with fall i)]owing, 

 the use of i)oison baits, and a short system of rotation. 



E-oot maggots, H. T. Fernald {Massachusetts Sta. Virc. 5, pp. 2). — The cal)- 

 bage maggot may be controlled at least in part by the use of tar paper collars 

 around cabl)age and cauliflower plants. Onion maggots are to be checlvod by the 

 application of carbolic acid emulsion. 



The melon louse, A. F. Conradi {Gvlf Coast Mag., 3 {1907), No. 1, pp. ^7- 

 53, figs. 6). — This pest has caused serious depredations since 1854. The nature 

 of the damage caused by the insect is briefly described. The best results in 

 combating the pest have been obtained from fumigation with a preparation of 

 nicotine. The encouragement of its natural enemies is also recommended. 



Some items of information for orchardists and fruit growers relative to 

 certain dangerously injurious insects and diseases, (J. G. Atwood (.V. Y. Dept. 

 Agr., Bur. Hoit. Iiisp. But. 1, pp. 20, pis. J/S). — For the guidance of fruit grow- 

 ers iu combating insect and fungus diseases, detailed directions are given for 

 the preparation of lime-sulphur wash and Bordeaux mixture for the control of 

 ►San Jose scale, peach yellows, leaf curl, crown gall, apple scab, grape root 

 worm, etc. 



The apple maggot or railroad worm, (J. E. Hood {Massachusetts Sta. Virc. 

 3, pp. 3, figs. 2). — The life history of this insect is briefly outlined. The only 

 remedy suggested for coml)ating the pest consists in collecting and destroying 

 all windfall ni^iles. 



The lecaniums or soft scales, C. E. Hood {Massachusetts Sta. Cire. 6, pp. 

 3). — Brief biological and economic notes on apricot scale, New York plum 

 scale, terrapin scale, tulip scale, and hemispherical scale. 



The San Jose scale, H. A. Surface {ZooI. Bui. Penn. Dept. Agr., 5 (1907), 

 No. 6, pp. 171-200, pis. //). — A brief account is presented as to the origin, inju- 

 rious attacks, food plants, appearance, distribution, life history, natural 

 enemies, and means of combating San Jose scale. Of the various insecticides
