an almost normal amount of cotton may be produced if no more than an average 

 weevil infestation occurs. If, however, the numbers of early bolls have already 

 been reduced by P_. seriatus , the losses become much more important.

Includes two articles on some of the more important insect pests that do 

 not occur or are not generally distributed in California, although found in other 

 parts of the U.S. 



The articles are: The Mexican and thurberia cotton boll weevil (A. grandis 

 Boh., and A. grandis thurberia Pierce), by J. W. Folsom (p. 212-215).

 bollworm infestation in northern Mexico. J. Econ. Ent. 25(4):772-776. 



Observations were carried out in 1931 on a heavy infestation of cotton by 

 Anthonomus grandis Boh., discovered in northern Mexico, in conjunction with an 

 infestation by Platyedra ( Pectinophora ) gossypiella Saund. Weekly records were 

 made of the percentage of square and boll infestations by both species. Multi- 

 plication and development of either pest was not checked by that of the other.

Opens with a general account of the anatomy, morphology, classification, and 

 biology of insects, and of the anatomy and morphology of mites. About 50 pages 

 are devoted to notes on the bionomics and control of the more important insects 

 and mites that attack cotton in the Russian Union; each species is described, and 

 a key to the aphids is included. Further notes are given on Platyedra 

 ( Pectinophora ) gossypiella Saund., and Anthonomus grandis Boh., in view of the 

 possibility of their introduction into the Russian Union, and the importance of 

 quarantines against pests is briefly discussed. A section of 68 pages deals with 

 various methods of control, spraying and dusting equipment, and the application 

 of dusts from aeroplanes. 



1935 - Bilsing, S. W. Creating an entomological atmosphere in the South. J. Econ. Ent. 



28(5):739-745. 



Emphasis is laid on the importance of preparing the public mind by dis- 

 seminating information concerning the potential dangers of insect pests in order 

 to obtain support when a campaign has to be initiated; and in order to stimulate 

 enthusiasm, the accomplishments of a few pioneers in entomological work in 

 the southern United States are reviewed. The manner in which the respective 

 menaces of the boll weevil ( Anthonomus grandis Boh.), the pink boll worm 

 ( Platyedra gossypiella Saund.) and the Mediterranean fruit-fly (Ceratitis capitata 

 Wied.) were dealt with there, is quoted to show what might have been accom- 

 plished had the public mind been sufficiently prepared for the advice offered in 

 the case of A. grandis, and what has been accomplished in the case of the other 

 2 pests.

Injury by insect pests was, in general, somewhat below the average in South 

 Carolina in 1935, but an increase in damage to cotton by Anthonomus grandis 

 Boh. was observed.
