A new enemy of the strawberry in Germany, H. Morstatt (Deut. Ltuuhr. 

 Prcsse, 3-5 (190S), No. 35, p. 370, figs. 9). — Tarsonetnus fmgariw is reported as 

 having caused great injury to strawberry plants by attacking the leaves. A 

 brief account is given of the appearance and habits of this mite. Most of tho 

 insecticides which have been tested for controlling it have proved to be of little 

 avail, and it has, therefore, been lately recommended that infested plants be 

 removed early in the season and destroyed. It is believed, however, that fre- 

 quent sprinkling of the plants with water alone or with a dilute solution of 

 ammonia might be beneficial. 



The use of arsenical compounds in the treatment of vineyards, H. Bektin- 

 sAXS and V. Ros {Rev. Ilijg. ct Pol. Sanit., 30 {1908), No. .',, pp. 281-286).— \ 

 lively controversy has recently developed especially in France regarding the 

 possible dangers from the use of arsenicals in spraying vineyards. The fear 

 has been entertained that such treatment might result in the passage of some 

 of the arsenic into the wine. The experiments reported by the author indicate 

 that the danger from the application of arsenicals in the eai'ly part of the 

 season is iiractically none, but it is considered advisable to prohibit the use of 

 arsenical insecticides after the grapes are in bloom. 



Combating- the olive fly, A. Berlese {BoI. Quind. Hoc. Agr. ItaJ.. 13 {1908), 

 Nil. 8, pp. 261-26.5). — Brief mention is made of the damage done to olives by 

 DacKS olete, together with a historical account of the development of the 

 method of using a mixture of molasses, honey, and an arsenical in coml>atiiig 

 this pest. It has been found that if 2 per cent of arsenic be added to a mixture 

 of equal parts of molasses and honey the mixture may then be diluted with 

 water and sprayed on olive trees with good results. 



The cocoanut beetle in Batticaloa, Ceylon, I-]. E. Green {Proc. Agr. Soc. 

 Trinidad and Tohago, 8 (1908), No. 3, pp. 10.5-109). — The cocoanut beetle is ex- 

 tending its range rather rapidly as shown l)y the numbers captured by superin- 

 tendents of cocoanut plantations and by the examination of cocoanut trees. 

 Considerable work has been done in combating this pest by cutting out and 

 burning the crowns and a few feet of the upper part of the stems of infested 

 trees. The trunks of trees destroyed for any purpose may be used temporarily 

 for fencing purposes, but as soon as they become decayed it should be understood 

 that they furnish excellent breeding grounds for the cocoanut beetle. 



The more important insects affecting Ohio shade trees, J. S. Houser (Ohio 

 tSta. Bui. 19.'i, pp. 169-2Jf3, fig^. .'/7). — A general account of the insect enemies 

 of shade trees of the State with directions for the preparation and applica- 

 tion of insecticides. Accompanying the account are numerous illustrations 

 of the insects considered, of the injury caused by them, and of spraying appa- 

 ratus used in their control. 



Forest injuries from insects, Hanff {Jahrh. HcJiIcsischen Forstver., 1907, 

 pp. 39-52). — The insect injuries which attracted most attention during the 

 year were due to Gastropacha pint, N^nintus abietrun, cockchafers, Pissodcs 

 piccw, gipsy moth, etc. The larvae of G. pini infested trees in some cases to the 

 extent of o,nOO or 4,0(10 per tree. In such cases the use of sticky bands was 

 very advantageous. 



Injury to Abies nobilis by Chermes piceae bouvieri, E. Molz (Nat una. 

 Zt.scin: Forsi u. Landir.. (! [1 90S), No. 2. pp. 151-15'i, figs. .)). — Vhcnncs 

 picca; honricri attacks the tips of growing shoots of Ahies nohilis causing 

 extensive malforniatifais in the form of galls. The injury thus produced is 

 quite serious, in some cases cnusing the death of the affected trees. 



Some coleoptera affecting the honey locust, C. O. Houc;nTox H'anad. En I., 

 'lO (I90S). \(,. 5. pp. 160-162). — I^arge numbers of Agrilus- falla.r were ob- 

 served feeding upon the leaves of the honey locust. Among the other coleop-
