 10(ll-12):6l4-626. Sacramento. 



The work of the Plant Quarantine Service of the U. S. D. A. during the year 

 ending June 30, 1921, is reviewed, and particulars are given of inspection at the 

 various stations. The conclusion is reached that if an adequate measure of pro- 

 tection is to be given against such serious pests as the cotton boll weevil, pink 

 bollworm, and others that are liable to be introduced through interior points and 

 at border points, a sufficient number of inspectors must be provided to insure 

 thorough inspection at the border lines and all terminals.

cotton pests that are not wanted in Puerto Rico). P. R. Insular Exp. Sta. C. 4, 

 9 p. Apr. Rio Piedras. 



The Puerto Rico Department of Agriculture requests all cotton growers to 

 cooperate in guarding against importing into the Island any cotton seed proceeding 

 from countries where the cotton boll weevil or Platyedra ( Pectinophora ) 

 gossypiella (pink bollworm) occur. 



1921 - Cantoni, L. A. Plant inspection and quarantine report (1919-20). P.R. Insular 



Expt. Sta. B. 27, 23 p., 4 tab. Rio Piedras. 



A description is given of the setting up in 1919 of a Technical Board to 

 supervise Plant Quarantine and Inspection. In January, boll weevils were found in 

 some unlawfully imported cotton seed, but there was no trace of the pest in the 

 area planted before inspection.

Hort. 12th & 13th Ann. Rpts. 1919-1921:17-64, 9 fig., 2 maps, 6 tab., Phoenix. 



The work of the various inspection services for 1920 and 1921 is reviewed. 

 The quarantine and other measures adapted against the Mexican cotton boll 

 weevil are given. 



1922 - Mote, D. C. Report of Arizona conditions. Calif. Dept. Agr. Mo. B. 11(8-9): 



625-628. 



The general lines of work for safeguarding the cotton crop in Arizona are 

 outlined. The quarantine against boll weevil and pink bollworm ( Platyedra 

 gossypiella ) is enforced with great thoroughness, inspection being made of all 

 packages entering by post, rail, or road. In a portion of Pima County a noncotton 

 zone was declared in November 1920, and was so successful that in 1921 a small 

 patch of selfsown cotton and a plot allowed to grow for observation purposes 

 were the only spots in which living weevils were found. The noncotton zone was 

 continued in 1922.

"There is considerable danger of Anthonomus grandis (boll weevil) being 

 introduced from America and of other pests from Uganda. The situation is being 

 watched." 



1923 - Froggatt, W. W. Insect pests of the cultivated cotton plant. New South Wales 



Agri. Gazette, No. 2, 34(l):6l-64, Jan. 1. Sydney. 



A brief account of Mexican cotton boll weevil and Platyedra ( Gelechia ) 

 gossypiella (pink bollworm), the two great cotton pests of the world. These pests 

 might easily be accidentally introduced into Australia either in the cotton seed 

 or in unginned or badly ginned cotton, and it is only by the total prohibition of all 

 seed from the countries where they exist and by careful examination and treat- 

 ment of all seed from elsewhere that they can be kept out of the Commonwealth.
