ENTOMOLOGY. 1091 



Coccidse of Ohio, J. G. Sanders {Ohio State Univ. Bui., 8. ser., No. 17, pp. 

 25-93, ph. 9). — Descriptive biological and economic notes are presented on all species 

 of the subfamily l)iaspin;e found in Ohio. In this suV)family 6 new species are 

 described. A list is also given of the species of Coccinte found in the State. An 

 analytical key is presented for convenience in identifying the genera and species. 



The San Jose scale in Japan, S. I. Kuwana et al. [Imp. Agr. Expt. Sta., Japan, 

 1904, lip. 33, ph. S). — An elaborate study was carried out by the entomologists of the 

 Imperial Agricultural Experiment Station of Japan for the purpose of determining 

 tlie origin, distribution, and means of combating San Jose*" scale. 



A description is presented of the liorticultural conditions of Japan with especial 

 reference to the bearing of these conditions upon tlie distribution of the scale. Notes 

 are given on the prevalence of the San Jose scale in the various provinces of the 

 Jai^anese empire. A long list of food plants is also presented. Contrary to supposi- 

 tion which has been made by various writers on the San Jose scale, this pest is not 

 found in high, uncultivated regions of Japan nor upon native species of wild pea-r or 

 apple. It is concluded as a result of these studies that the San Jose scale was intro- 

 duced into Japan in 1871 on infested stock shipped to Awoyama. The pest has sub- 

 sequently been distributed on trees sent all over the empire. 



Low and comparatively moist regions appear to be favorable to the development 

 of the San Jose scale. The natural enemies mentioned l)y the author are Chilocorus 

 sirnili.s which is said, however, to prefer Diaspis pentagoua and also the parasitic fun- 

 gus (Sphxrostilhe coccophila). It is stated that the Japanese have thus far not used 

 power pumps in combating this insect nor has fumigation with gas been practiced. 

 The best results have been ol^tained from the use of kerosene emulsion. 



Injurious effects of the round-headed apple-tree borer, W. Stuart ( Vermont 

 Sta. Rpt. 1903, jip. 204—208). — The round-headed apple-tree borer caused consider- 

 able damage during the year. Brief notes are given on the life history and hal )its 

 of this insect, and on preventive and remedial measures which have been recom- 

 mended. 



Directions for spraying for the codling- moth, C W. Woodworth {California 

 Sta. Bui. 1,J5, pj). 20, Jigs. 4)-- — <-*f the various methods tested by the author in con- 

 trolling codling moth the only one which has given encouraging results is the appli- 

 cation of arsenical sprays. For this purpose the best substances are Paris green, 

 arsenite of lime, and lead arsenate. Paris green gave as good results as any other 

 arsenical, and in localities where it is ajit to injure the foliage the author recommends 

 that lime be added in quantities 5 to 10 times as great as the Paris green. 



Lead arsenate proved to be the safest of all arsenicals, but was less effective 

 than either Paris green or arsenite of lime in the destruction of the codling moth. 

 A mixture of Paris green, oil, and lime was tested on a small scale, with good results. 

 This mixture was i)rei3ared by stirring I lb. of Paris green into a jiint of crude oil; 4 

 or 5 lbs. of lime were then slaked and the Paris green and oil added and stirred until 

 the lime linited with the excess of oil. The material was tlien diluted to 150 gal. 



In sjjraying for the codling moth in California 3 ajiplications appear to be neces- 

 sary. The first should be made at the projjcr time for thoroughly poisoning the 

 inside of the calyx lobes in order to destroy larva* which may subsequently attempt 

 to enter the apple at that place. The author maintains that it is useless in making 

 this application to direct the spray anywhere except against the blossoms from above. 

 The second application should ])e made at the time when the eggs are laid. At this 

 time the spray should be applied to all parts of the leaves and fruit. The third 

 application is considered the most important, and is directed against the larvte of the 

 second brood.
