Book excerpt: Excerpt from Studies of Parasites of the Cotton Boll Weevil The boll weevil has been present in the United States for fourteen years. At this time it is doing serious damage to cotton in four States, and during the present season undoubtedly will invade a fifth. In regions like Central America, where the insect has existed for many years, there are various influences that serve to hold it in check. In this country Similar influences are beginning to be in evidence. Among the direct factors in the natural control Of the boll weevil that are now at work are the following: Heat and dry ness, the native ant Solenopsis geminata, winter temperatures, proliferation, parasites, defoliation by the cotton leaf-worm, deter minate growth, and birds. Of these, proliferation and birds have already received careful special attention, while the work of the native ant has received preliminary notice. The other factors have also been more or less discussed in the publications of the Bureau of Entomology and elsewhere, and more extensive studies of certain ones will be discussed by Dr. W. E. Hinds in Bulletin No. 74 of this Bureau. While the work of parasites, discussed in this bulletin, is not. At present one Of the most important factors in the control of the boll weevil, the indications are clear that its importance will grow rapidly. Moreover, the matter has special interest for the reason that it is not unlikely that practical means may be devised to increase the work of the parasites.
