In 1917 the damage caused by the boll weevil in Georgia amounted to from 

 25% to 75% of the crop. A map showing the infested area and the determination of 

 the 20-mile safety line is given. The regulations governing transportation of 

 cotton seed, seed cotton, bolls, seed cotton and cotton pickers' sacks, and related 

 items, directed against the spread of this pest, are recapitulated and brought up 

 to date.

"An important Order-in-Council was published on July 25 under the 

 Importation of Plant Diseases Prevention Ordinance (1906) prohibiting the im- 

 portation of cotton seed and seed cotton into the colony from an outside source. 

 Though primarily intended to prevent the introduction of the Mexican cotton boll 

 weevil and pink bollworm, it also aimed at the exclusion of certain pests and 

 diseases occurring in other parts of the West Indies, but not found locally."

"The area in Florida infested by the cotton boll weevil (A. grandis) has 

 gradually increased southward and eastward owing to the migration of the adults 

 by flight, a spread that cannot be prevented and that results in the insect invading 

 new territory each year. The enforcement of quarantine measures, however, 

 which prohibit the removal from weevil-infested territory of cotton seed, seed 

 cotton bolls, Spanish moss, maize on the cob, and certain other materials, except 

 at certain seasons and under certain conditions, has undoubtedly prevented the 

 establishment of the pest ahead of the advancing line of migration."

To insure the future success of cotton growing in California, the necessity 

 of carrying out the inspection and quarantine service on a more adequate scale 

 is emphasized. So far the cotton boll weevil and the pink bollworm, Pectinophora 

 gossypiella, have not gained entry into the State.

Attention is drawn to the permits that are necessary in respect of importa- 

 tions of cotton seed. Permits are given only for seed to be sown, and then only 

 to the extent of 10 lbs. of a variety to any one applicant. The importance of 

 these restrictions has been indicated several times in the past year by the finding 

 of the pink bollworm (Platyedra gossypiella) in small parcels of North African 

 seed, and, during the past month, by the presence of a few dead adults of the 

 Mexican boll weevil in a parcel of seed from the United States.
