The cotton boll weevil is described in its various stages, and notes are given 

 on the various other phases of the weevil problem, such as the rate of increase and 

 destructiveness of the pest, artificial remedies, the relation of birds to the boll

A brief outline of the work carried out by the Comision de Parasitologia 

 during 1905 and the plan of work for 1906. The various methods of control are 

 discussed at length. These include the seed to be used, method of preparing the 

 soil, planting, cultivating, using trap plants, shaking the weevils from the plants, 

 using special machines, the breeding and distributing a native ant- -the kelep or 

 Guatemalan ant- -using poisons, planting of special varieties of cotton, and vari- 

 ous ideas regarding weevil control. New projects to be undertaken by the 

 Comision are mentioned.

 22, 16 p. 



On account of the serious damage caused by the boll weevil in the Southern 

 States, a special effort was made to obtain reliable information concerning birds 

 which feed upon this pest and the amount of assistance which may be expected 

 from them in protecting the cotton crop. 



Considering the fact that for the past 12 years the weevil has been steadily 

 spreading over the cotton belt, it appears that birds cannot be depended upon to 

 exterminate the pest. As a result of field observations and examinations of birds' 

 stomachs in the laboratory, a considerable list of birds was determined as feed- 

 ing upon the weevil. This list includes Carolina wren, titlark, tonitit, western 

 meadow lark, Florida meadow lark, common phoebe, redwing blackbird, white 

 throated sparrow, western savanna sparrow, brown thrasher, Texas bobwhite, 

 blackbird, co f wbird, jackdaw, mocking bird, butcherbird, killdeer, and others of 

 less importance.
