860 EXPERIMENT STATION EECORD. 



lbs. of sulphur per 50 gal. of water. All of the petroleum mixtures proved 

 fairly satisfactory, but it is stated that perhaps do one would be justified in giv- 

 ing up lime-sulphur wash for any of these preparations. If a serious infesta- 

 tion of San Jose scale should occur in summer, the trouble may be somewhat 

 relieved by spraying with a 20 per cent kerosene emulsion. 



The use of soluble oils against San Jose scale, W. W. Chase (Gfl. Bd. Ent. 

 Circ. 6, pp. It, figs. Jf). — A number of proprietary and miscible oil preparations 

 were tested against San Jose scale. These appeared to be al)out ecpially effica- 

 cious, as comi^ired with liiup-sulpluir-snit wasli, which is also highly efficient, 

 and have the one advantage of being more easily applied. 



The sulphur-lime wash, A. L. Melander ( Wai^hingtori Sta. Popular Bui. 2, 

 pp. .'/). — The formula recommended for sulphur-lime wash is 1 lb. sulphur and 

 1 lb. lime per 4 gal. water. The mixture should be boiled for ;>0 minutes to 

 1 hour. Directions are given for the application of this wash in the treat- 

 ment of A^arious scale insects and other pests. 



Phylloxera vastatrix, H. Stauffacher {Ztschr. Wiss. Zoo/., 8S (J 907), No. 1, 

 pp. 13l-l.')2, pi. 1, figs. 5). — An elaborate description is given of the anatomy of 

 this insect in its immature and adult forms, together with notes on its life 

 history. 



The bagworin, L. O. Howard and F. H. Chittenden ( U. S. Dept. Agr., Bur. 

 Ent. Circ. 97, pp. 10, figs. 11). — During 1907 the bagworm caused an unusual 

 amount of injury in various parts of the country. This insect is a general 

 feeder, but appears to prefer arborviliT^ and other evergreens. Notes are given 

 on its habits, life history, and natural enemies. On deciduous trees the insect 

 may be controlled by ])icking off the bags in winter. On evergreens this is 

 more difficult, l)ut the pest may be controlled by spraying with Paris green 

 at the rate of 1 11). per ir>(» gal. of water. 



Observations on Chermes pini, P. Marchae (Cotiipt. Rend. .S'oc. Biol. IParis], 

 63 {1907), No. 29, pp. 3. ',0-3 J/ 2). —The stem mothers are found in the first larval 

 stage at the base of the leaves of Picca oricntulis. The winged migrants mi- 

 grate to species of pines (Piniis sylvestris and P. strobus). Other points in the 

 life history of this insect are mentioned together with notes on its distribution. 



A mite accompanying the bud rot of carnations, R. H. Wolcott (Nebraska 

 Sta. Bill. 103, pp. 2')-3l, pis. 2). — In connection with the bud rot of carnations 

 a mite was found in affected flowers which is described as a new species under 

 the name Pcdiculoidcs diantlioptiiliis. This mite belongs to the family Tarsone- 

 midfe and is viviparous. It apparently is concerned in distributing the fun- 

 gus which causes bud rot. 



Ants, C. E. Hood (Massachusetts Sta. Circ. 7, pp. 2). — Monomorinni pharao- 

 nis may usually be destroyed by pouring bisulphid of carbon or kerosene emul- 

 sion into the nest. The use of sweetened baits is also recommended. 



The grouse fly, D. Sharp [Ent. Mo. Mag., 2. scr., 18 {1907), No. 207, pp. 

 58-60). — Lagopus scoticus, a common species of grouse in Scotland, was found 

 to be quite regularly infested with a fly which is described as a new species 

 under the name Ornitlioini/ia htgopodis. 



The ox w^arble fly and means of combating it {Laitdiv. Wchnbl. Schles. 

 Hoist., 57 {1907), No. 35, pp. 570-573, figs, j).— The life history of the warble fly 

 is briefly outlined. In the author's opinion, the best means of combating the 

 pest consists in removing the larvjB from the skin of infested animals as soon 

 as they have reached a size sufficient to enable the cattle raiser to detect 

 ■them. It is suggested that cattle raisers should combine and work coopera- 

 tively. 



Experiments with Paris green, A. Tullgren and C. G. Dahl (Meddcl. K. 

 Landtbr. Styr. [Sweden], 1907, No. 6 {125), pp. ^5). — During the seasons
