 Capulho nos Agodoeiros do Nordeste. [Reporfc on the Pink Boll 

 Worm in the Cotton Districts of North-eastern Brazil.]— Rio de 

 Janeiro, 1917, 50 pp., 4 plates. 



This is a report to the Brazilian Minister of Agriculture on Pectino- 

 phora (Gelechia) gossijpiella (pink boll worm) infesting cotton in the 

 north-eastern States of the Republic. The introduction of this pest, 

 which was discovered early in 1916 in the State of Ceara, may date 

 back a long time and its spread is anticipated to be slow. The larvae 

 also attack the seed of Hibiscus and its allies. Pediculoides ventricosus, 

 Newp., preys on P. gossijpiella in Brazil, and two ants, Monomorium 

 sp. and Cremastogaster sp., have been noticed attacking it accidentally. 

 A Bethylid, Perisierola m^/n/ew?;/, Ashm., a Chalcid, Solindemia sp., 

 and two Braconids, Coelothorax sp. and Bracon sp., were taken from 

 infested bolls. The best that can be expected of these natural enemies 

 is a check on an excessive increase of the pest, the usual remedial 

 measures for which are briefly described. 



This report closes with notes on the following further insects on 

 cotton in the north-east of Brazil : — In the seed : a Bruchid, 

 Spermophagus sp., an Anthribid, Araecerus fasciculatus, De G., a 

 Curculionid, Hyperodes sp., and a moth, Pyroderces simplex, Wlsm. 

 At Fortaleza the author found a larva, apparently that of Heliothis 

 ohsoleta. On the plants : a Noctuid, Alabama (Anomis) argillacea, 

 Hbn., a cotton-stainer, Dijsdercus sp., Aphis gossypii, Glov., and a 

 scale, probably Hemickionaspis tninor, Mask.

Against Cydia {Carpompsa) funebrana injuring plums in Catalonia, 

 the usual remedies are advised, including light-traps, alkaline washes, 

 sulphur sprays (applied after blossoming), removal of infested fruit, 

 and shelter-traps. During the blossoming period, a spray containing 

 1 lb. sodium arsenate and 5 lb. lime (paste) in 50 gals, water was tried 

 and appeared to give good results.
