plants at the time of stripping. Any kind of syrup can be used, but the better the 

 grade of syrup, the higher the percentage of control that will be secured. It is de- 

 sirable that the mixture retain its syrupy consistency as long as possible. 



Mopping, with mops made by tying shucks or pieces of burlap on the end of a 

 stick, was found to be more successful than shaking the syrup mixture out of a 

 bottle. By gently pressing the mop down into the bud of the plant there is practically 

 no chance of the weevil escaping the poisoned-syrup mixture. On the other hand, if 

 a drop or two of the mixture is shaken from a bottle onto the top leaves of the 

 plant, there is a chance that the weevil will not find the poisoned syrup until after 

 it has been rendered harmless, either by dew or rapid evaporation. 



Recommendations are given for cotton growing in 1924, including the appli- 

 cation of the Florida method described above. On very fertile lands it might be 

 profitable to lengthen the period of weevil protection by giving one or two appli- 

 cations of calcium arsenate during July, or when the infestation of squares has 

 reached 15% or 20%. Such late applications are expensive and are not likely to be 

 profitable on poor or average land. The cotton crop should be picked as fast as it 

 opens, and immediately after harvest all plants should be totally destroyed.

In order to obtain data on the growth and fruiting habits of early and late 

 planted cotton in relation to the cultural control of the boll weevil, many experi- 

 ments were made in 1923 and comparisons were drawn between the behavior of 

 early and late plantings in Texas and South Carolina. The differences in the rates 

 of growth and the fruiting habits of the plants are discussed in detail. In view of 

 variations in results and of the fact that the later rows of successive plantings were 

 only partly protected against weevils from the earlier rows, the experiments 

 were in no way conclusive.

"In 1924 cotton planted between May 1 and May 15 was damaged more by jP. 

 seriatus than that planted before or after. It was concluded that early planting is 

 preferable to late, as in more normal seasons cotton planted after May 15 would 

 probably be severely damaged by the boll weevil ..."

General recommendations are to insure correct time of planting, using an 

 early maturing variety of cotton, and to retain a continuous soil mulch until the 

 bolls begin to open. In cases of severe infestation over a large area, the whole 

 community should practice early gathering of the infested squares. Punctured 

 squares should be gathered for 6 weeks after the first ones appear and placed in 

 a parasite cage. Final picking of cotton should be completed as early in autumn 

 as possible, and all plants should be destroyed immediately afterwards and the 

 fields thoroughly cleaned up. After ginning is completed, all gin trash should be 

 removed and enclosures prepared for seed and bolls, so that hibernating weevils 

 can only escape into screen traps. Cotton fields and seed beds should be prepared 

 in advance, and made compact, moist, and warm, to insure uniform germination 

 and quick growth. Only as much cotton should be grown as can be thoroughly cared 

 for.

Though early in the season, Sea Island cotton affords less opportunity than 

 upland cotton for the breeding of boll weevils. In the later stages of development 

 the former variety is the more susceptible of the two to injury, owing to the 

 thinner walls and softer texture of the bolls. The experiments showed that heavily 

 fruited plants of sea-island cotton may have the crop completely destroyed by
