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.

This book was released on 2018-10-02 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Proliferation as a Factor in the Natural Control of the Mexican Cotton Boll Weevil As the significance of these observations came to be more fully appreciated it was believed that they contained at least a suggestion as to some very promising lines of work in the problem of controlling the weevil. Accordingly, it has been necessary to study carefully the nature of the phenomenon, conditions of climate, soil, fertilizer, and variety of cotton which affected the occurrence of proliferation. Observations have, therefore, been made upon quite a large number of varieties and in locations ranging from Victoria to Dallas, Tex., upon various types of soil, and in connection with various experiments with fertilizers and different conditions of cultivation. From a comparison of the results thus obtained it was hoped that some factors might be found which could be used practically in increasing proliferation, and thus rendering it more effective as a factor in controlling the weevil. In many cases the results of the work have been quite different from those anticipated, but enough has been learned to justify the assertion that at present proliferation is a more important factor in retarding the multiplication of the weevil than are the parasites which have thus far been found. Large numbers of squares and bolls have been carefully examined in obtaining these records. In the examination of bolls, the lock has been made the unit rather than the boll. As a general rule, a larva confines its injury almost, if not entirely, to the lock within which the egg was originally placed. Quite frequently two or more larvae occur within a look, but even in such cases the injury does not often extend through the septum or partition which separates the locks. In making a comparison of varieties considerable care is required in subdividing the classes of observations in order to render the infin ential conditions sufficiently uniform to make the observations fairly comparable and wherever possible to reduce the fundamental causes or stimuli producing variations in the proliferation to one essential factor. While the phenomenon in bolls is of a similar nature to that in squares, conditions in these two cases are so different that the results are not strictly comparable, and therefore separate tables have been made for squares and bolls. The effects of feeding and egg punctures also call for separate classification. This treatment of the subject necessarily multiplies the number of tables, but we hope that it will render the results more easily intelligible. The personal equation of the observer has been equalized by combining the records made by a number of investigators.
