 vol. 27, No. 51, p. 3, December 19. 



Brief statement regarding boll weevil conditions in Texas. Injury during 1908 less than 

 during preceding years; reasons for scarcity assigned. Principal methods of control 

 outlined. 



No. 172. Hunter, W. D., 1908. — Regarding late planting to avoid damage by the 

 boll weevil. <Bul. 120, Miss. Agr. Exp. Sta. Farmers' Institute Bulletin, 

 1907-1908, pp. 17-24, December. 



A review of the history of the late-planting theory as a means of boll weevil control and a 

 collection of data, based mainly on experiments of the Bureau of Entomology, which show 

 the fallacy of this idea. 



No. 173. Hunter, W. D., 1909. — Boll wee\dl situation in Oklahoma. <Monthly Press 

 Bui. 7, Okla. State Bd. Agr., pp. 2-3, September 1. 



A statement regarding the scarcity of boll weevils in Oklahoma due to the heat and 

 drought. The early fall destruction of stalks is urged so as to take advantageof the natural 

 setback the weevil has received. 



No. 174. Hunter, W. D., 1909. — The boll weevil problem with special reference to 

 means of reducing damage. <Farmers' Bui. 344, U. S. Dept. Agr.,

This bulletin gives the most comprehensive treatment of the various means of boll 

 weevil control yet issued. The introductory paragraph contains a brief account of the 

 investigations of the pest, with a history of the infestation of the cotton region. The 

 prospect for damage in the future and in new regions is discussed, as also the work upon 

 which the bulletin is based. A concise account of the life history and brief description of 

 the insect is given, and a discussion of its hibernation and the several factors of natural con- 

 trol. The subject of dissemination receives concise treatment. Means of control are dis- 

 cussed at length. Under"means of controI"are the following subdivisions: Burning in- 

 fested plants in the fall; methods of destroying weevils in the fall; destruction of weevils in 

 hibernation places; locating fields to avoid damage; crop rotation; procuring an early crop; 

 additional expedients in hast eniug the crop; special devices for destroying the weevils (under 

 this topic is given a complete description of a chain cultivator, devised by Dr. W. E. Hinds, 

 and remarks regarding its uses); hand picking of weevils; topping of plants; cotton-leaf worm 

 and boll weevil; destroying the weevil in cotton seed; relation of means of controlling 

 the boll weevil to the control of other insects; general control tlirough quarantines; 

 attempts to poison the boll weevil; false remedies; summary; special treatment of small 

 areas. 



No. 175. Hunter, W. D., 1909. — What can be done in destroying the cotton boll 

 weevil during the winter. <Cir. 107, Bur. Ent., U. S. Dept. Agr., 4 pp., 

 January 12. 



Emphasis is placed on the desirability of following early fall destruction of cotton plants 

 with general clearing up of all places likely to offer hibernating quarters for the weevil. 



No. 176. Hunter, W. D., 1909.— The boll weevil situation.<Texas Stockman & 

 Farmer, vol. 28, No. 43, p. 4, October 13. 



An address at the Tri-State Fair at Memphis, Tenn. Statistics are given showing the 

 effect of the weevil upon cotton production in Texas. The weevil situation in the Missis- 

 sippi Delta is discussed and the various obstacles met in the fight against the weevil in 

 that region are pointed out. Remedial practices are mentioned. 



No. 177. Hunter, W. D., 1910.— The status of the boll wee\'il in 1909. <Cir. 122, 

 Bur. Ent., U. S. Dept. Agr., 12 pp., 1 fig. 



A concise statement of boll weevil conditions in 1 909. .\n estimate is made of the percent- 

 age of the cotton area of each State which was infest ed at the end of t he season in 1909. A dis- 

 cussion is given of the factors which tended to reduce damage during 1909 and of the dis- 

 persion during that year. Under "History in Texas" appears a discussion of the cotton 

 production in different sections of Texas. This nicely illustrates the effect the weevil has 

 had on the cotton production of the State. The results of experiments with a chain culti- 

 vator designed by Dr. W. E. Hinds are given. The parasites of the weevil are briefly 

 treated and a summary is given of the work by Messrs. Newell and Smith (see No. 239) on 

 the use of powdered arsenate of lead against the weevil. Some of the possible disadvantage! 

 of the useof arsenate of lead are set forth.
