"A weevil, Anthonomus sp., abounds in the flowers and attacks the bolls 

 (cotton); an inquiry was sent to the United States to ascertain if the species is 

 A. grandis."

Laguna District). Mex„ Rev. Agr. 6(9):504- 51 3, 13 fig. Jan. 



The information in this paper is largely concerned with Platyedra 

 (Pectinophora) gossypiella (pink bollworm), which is the worst pest of cotton 

 in the Laguna District of Mexico. Of less importance is Anthonomus grandis, 

 which, under normal conditions, can never be a very severe pest in the district. 

 It is endemic in the region and increases in numbers towards the end of autumn.

At the beginning of the season 1921-22 the cotton boll weevil was very 

 abundant throughout Texas, but owing to weather conditions the damage was less 

 serious than had been anticipated. 



1922 - Morrill, A. W. Arizona wild cotton or thurberia and its insect enemies in rela- 

 tion to the cotton industry of the Southwest. J. Econ. Ent. 14(6):472-478. 



Experience with the cotton boll weevil shows that the maintenance of narrow 

 noncotton zones, as suggested by Arizona officials, does not stop the progress of 

 the weevil. This pest will cross a 5- or 10-mile noncotton zone faster than if it 

 were planted entirely with cotton. Relationships between weevil and foodplant 

 having been disturbed during a critical period and at a place where easily thrown 

 out of adjustment, the outlawed cotton plantings become valuable as trap crops. 

 Under the circumstances the more cotton grown in a prohibited area, the better 

 would be the protection of the more important cotton sections within range of the 

 2 pests here dealt with, A. grandis thurberiae Pierce and Thurberiphaga catalina 

 Dyar ( thurberiae bollworm~7i

A brief account of the principal insect pests occurring in the Southern 

 States, including the boll weevil, with recommendations for their control. They 

 are arranged, as far as possible, under their respective foodplants.

A general account is given of Anthonomus grandis Boh., in view of the im- 

 portance of keeping this pest out of the French colonies, where cotton cultivation 

 is being taken up. 



1923 - Aigin, I. Mexican cotton boll weevil. Cotton Indust. 2(5-6):54-58. Moscow. 



A general account of the injury caused by Anthonomus grandis to cotton in 

 North American States and the remedial measures employed against it. Though 

 this weevil has not as yet occurred in Turkestan where climatic conditions would 

 appear to be unfavorable to its establishment, the possibility of its introduction 

 must not be lost sight of, especially in connection with the importation of 

 American cottonseed.

The cottons tested were from the crop in 1921 and consisted of the fiber of

 of the kind commercially known as "North Georgia." The Acala cotton was
