Problems relating to the new pest of Egyptian cotton, the pink bollworm 

 (Gelechia gossjrpiella), L. H. Gough {Bill. Union Agr. Egypte, 12 (1914), Xo. 

 101, pp. 196, 197; abs. in Rev. Appl. Ent., 2 (1914), Ser. A, No. 10, p. 596).— The 

 author reports that the number of generations per annum of the pink bollworm 

 in Egypt varies from one to six. After the growth of the larvte has been com- 

 pleted a hibernation or estivation of from one week to an indefinite time may 

 take place before they transform to pup;ie. 



Four natural enemies, namely, Piinpla rotorator, Chclonella sulcata, Lim- 

 neriuni interniptum, and Pcdiculoides ventricosus, together with Microsporid- 

 ium polyhedricum, are capable of reducing the number of hibernating larvse to 

 40 per cent or less. 



An enemy of cultivated carnations, Molixas (BuL Sac. Xat. Agr. France, 

 74 (1914). -Vo. 4. pp. 476-481; abs. in Rev. Appl. Ent., 2 {1914), Ser. A, No. 10, 

 p. 620). — 'fhe tortricid moth Tortrix pronubana, of which there are four 

 generations annually, is Siiid to attack frequently carnations cultivated on the 

 coasts of Provence and of Italy. The species, though quite polyphagous and 

 found in the greater part of France on indigenous plants belonging to widely 

 separate families, has not been reported a source of injury to cultivated plants. 

 As high as 400 eggs may be deposited in batches of from 30 to SO eggs. The 

 larvfe live in the leaves and flowers. Several parasites which are important 

 aids in its control have been reared by the author. Fumigation has not been 

 found to be effective and hand destruction has to be resorted to. See also a 

 previous note (E. S. R., 30. p. 356).
