160 EXPERIMENT STATION' EECOED. 



Kerosene remedy and the fruit fly, G. Compeke {Jour. Dept. Agr. West. 

 Aust., 1') (1907), yo. .'/, /*/). ;?-'/.'/, 2Jt5, pi. 1). — A self-feeding kerosene trap has 

 been devised which seems to have been quite effective in catching the fruit fly. 

 According to the author's experience the odor of Icerosene attracts this insect. 



Combating codling moth with arsenicals, J. Barsacq {Jardin, 21 {1901), 

 No. .'iS.'i, pp. 12'i-]2G, fif/x. 2). — Mixtures of Paris green. lime, and flour in water 

 were used in spraying to comljat the codling moth. It is considered that the 

 first application should be made while the calyx is still open and that this 

 should be immediately repeated if followed by a rain storm. In these experi- 

 ments control trees showed 14.45 per cent of infested fruit, while trees sprayed 

 with the Paris green bore only 7.46 per cent of wormy apples. Arsenate of lead 

 in Bordeaux mixture gave still better results, the percentage of infestation 

 being 2.15. 



The terrapin scale, J. G. Sanders (V. S. Dept. Agr., Bur. Ent. Circ. SS, pp. Jf, 

 figs. 3). — A detailed description is given of EuJecnniuin nigrofasciatiim with 

 notes on its food plants and natural enemies. This pest affects chiefly peach 

 trees. It can not be satisfactorily controlled with the lime-sulphur wash, but 

 kerosene enuilsion gives good results. 



Notes on Chermes, Borner {Mitt K. Biol. Anst. Lavcl ii. Forstw., 2 {1907), 

 No. J/, pp. ').'i-60, figs. ,?).— The various stages in the life cycle of Chermes 

 strohilohiiis and C. (iJ)irtis are presented. 



The history of certain insect pests of the olive, A. Berlese {Redia, J/. 

 {1907), No. 1, pp. 1-180, pis. ,3, figs. (10). — A detailed report is made on the 

 Avork of the Royal Agricultural P]ntoniological Station at Florence on olive 

 insects, particularly olive fly, Lasioptera bcrlesiana. Lccanimn olar, PhUippia 

 olc(C, etc. The author calls attention to the great variation in the numbers of 

 these insect pests which appear from year to year. This variation appears to 

 be due largely to the relative prevalence of their natural enemies, particularly 

 parasites and predaceous insects. In combating the olive fly it is stated that 

 excellent results have been obtained for a number of years from the use of a 

 mixture containing G5 parts of molasses, 81 parts of honey, 2 parts of glycerin, 

 and 2 parts of arsenlte of soda. 



Combating the olive fly, J. Aguet {CoUivHtorc, 53 {1907), No. 19, pp. 586- 

 590). — In the author's opinion too little attention has been given to the natural 

 enemies of the olive fly in the systems of artificial treatments which have been 

 devised for its control. 



Insects affecting park and woodland trees, E. P. Felt {N. Y. State Miis. 

 Mem. 8, vols. 1, pp. l-3S2+a33.3-aJf59 ; 2, pp. 333-877, pis. 70, figs. 223).— For a 

 number of years the author and his assistants have beeii working on a compre- 

 hensive account of the insects of forest and shade trees. The present work is 

 the most elaborate on the subject which has appeared in the United States 

 since the fifth report of the United States Entomological Commission, by Doctor 

 Packard. Both volumes are elaborately illustrated. 



The subject material includes a general account of the biology of insects and 

 the means of preventing their attacks and detailed economic discussions of all 

 of the more important insects of forest and shade trees. These are classified 

 primarily into borers, leaf feeders, and sucking insects, and again into the ene- 

 mies of deciduous trees and coniferous trees. Bibliographical notes are given 

 throughout the text, and a supplemental bibliography on forest insects is 

 appended to volume 2 (pp. 701-755). 



Wood wasps, U. S. Macdougall {.Jour. Bd. Agr. [London], IJ/ {1907), No. 2, 

 pp. 98-lOJh figs. .'f). — The habits and life history of the genera Sirex and Xiphy-
