 Vine.] — Rev. Viticulture, Paris, xlviii, no. 1227, 3rd January 

 1918, pp. 5-10, 1 plate. 



Much of the information contained in this paper has been previously 

 given [see this Review, Ser. A, v, p. 339.]. The natural enemies of the 

 Curculionid pests of the vine are enumerated. In addition to insecti- 

 vorous birds, the enemies of Byctiscus betulae {Rynchites betuleti) 

 include the predaceous wasp Cerceris ferreri, Lind., and the Hymenop- 

 terous parasites Pimpla flavipes, Ratz., Bra con discoideus, Wsm., 

 Diospilus capito, Nees, Apanteles hoplites, Ratz., and the Chalcids 

 Elachistus idomene. Walk., and Poropoea defilippii, Rond. The last- 

 named develops in the eggs, just as Oophthora semblidis, Auriv., infests 

 those of Polychrosis hotrana and Clysia ambiguella. Insect enemies 

 of OtiorrJiynclnis sidcatus include various Carabids {Carabus, Feronia, 

 etc.) and Cerceris arenaria, L. 



Minor pests belonging to the genus Otiorrhynchus that attack vines 

 in France include : 0. singularis, L., 0. ligustici, L., 0. tenehricosus, 

 Hbst., 0. raucus, F. In Germany, 0. tristis does similar damage ; 

 in Austria-Hungary, 0. planatus, Hbst., and 0. longipennis, Stierl. ; 

 in Italy, 0. globus, Boh., 0. corruptor. Hbst., and 0. zebra, F. ; in 

 Greece, 0. graecus, Stierl. ; in southern Russia, 0. asphaltinus. Germ., 

 and 0. turca. Boh. These species all cause damage very similar to 

 that of 0. sulcatus and should be controlled by the same methods. 

 Leaf-eating species belonging to the alhed genus Peritelus include 

 Peritelus senex, Boh., P. griseus, Ohv., and P. subdepressus, Muls.

Scale-insects on vines have recently been developing rapidly in 

 the south-west of France. Both Eulecanium persicae and Pulvinaria 

 vitis are included in records of recent infestation, though neither 

 species constitutes a serious danger to the vine. P. vitis is found 

 chiefly on vines trained over the walls of houses or those grown in 

 unhealthy positions, and sometimes on old vines with very rough 

 bark. Most of the insects are destroyed when the vine is pruned, 

 and there are but a few individuals left on the old wood to continue 

 the next generation. It is easy to crush the few ovipositing females 

 that have remained until the next spring. If necessary the bark 

 should be scraped in winter.

A brief description is given of all stages of Argyroploce {Olethreutes) 

 variegana. This Tortricid pest of fruit trees occurs in central and 

 southern Europe, as w^ell as in Livonia, Finland, Sweden and Asia 

 Minor. In Italy adults were observed to emerge in May, and oviposition 

 took place in captivity from about mid-May to mid- June, 170 eggs 

 being laid on an average. It is probable that under natural conditions
