Excerpt from The Vegetable Weevil The primary injury by the vegetable weevil larvae is caused when they devour the buds of the host plants, stunting them (fig. And later the foliage, with the exception of the main stems and larger veins. The loss of the leaves not only interferes with the normal functioning of the plants but affects the market value of the crops (figs. 4, 0; In the South the leaves of turnips have a greater market value than the roots. Even though the infestation is not severe enough to cause noticeable injury, the mere presence of the larvae lowers the market value of the crops. Growers in the Crystal Springs district of Mississippi have reported losses as high as 90 percent, and losses of 40 to 70 percent are frequent. During 1933 the estimated crop losses for tomatoes alone ranged from 5 to 70 percent of the total value of the crop. Normally acres or more are planted to this crop each year in this district. Entire plantings of turnips (fig. Carrots, cabbages, mustard, and spinach have been destroyed or injured seriously during the early stages of growth by this weevil, and the growing of carrots on a commercial scale in this district has been practically aban doned.

Excerpt from The Vegetable Weevil: Listroderes Obliquus Light Experimenta - Experiments were undertaken to determine whether or not the vegetable weevil would fly, with-the idea in mind that if they did, light traps might be used for control. A large gasoline lantern was set up in a heavily infested field of carrots. The lantern was lighted about seven 0 'clock in the evening and kept lighted until nine o'clock. Surrounding the light were large frames covered with paper smeared with tanglefoot. Besides the white light Of the lamp, blue, amber, red, and green screens were used for a number Of evenings in May when the young adults were emerging from the ground. At no time were weevils seen in flight, but were readily found walking on the ground and feeding on the foliage of potato plants growing closely adjacent to the infested carrot field.

Back and Cotton (9, p.

Book Description
Excerpt from The Boll Weevil Problem: With Special Reference to Means of Reducing Damage This bulletin, dealing with work done under the direction of Dr. L. O. Howard, Chief of the Bureau of Entomology, is intended to cover in a general way the whole field of the control of the boll weevil. As this control is inseparably connected with the life history and habits of the insect and, in fact, must be based thereon, attention is given to the principal features of the insects economy. In addition, information is given relating to the amount of damage done, the extent of the infested territory, and such other matters as are of special interest at this time. Like many of the most important injurious insects in this country, the cotton boll weevil is not a native of the United States. Its original home was undoubtedly in the plateau region of Mexico or Central America, and it may originally have fed upon some plant other than cotton. This is not necessarily the case, however, since there is evidence that the same region is the original home of the cotton plant itself. Previous to 1892 the insect had spread through Mexico, but little is known regarding the extent or rapidity of this dispersion. The records indicate, however, that it had probably caused the abandonment of cotton in certain regions. About 1802 the boll weevil crossed the Rio Grande near Brownsville, Tex. It may have flown across, or it is possible that it was carried over in seed cotton to be ginned at Brownsville. By 1894 it had spread to a half dozen counties in southern Texas and was brought to the attention of the Bureau of Entomology. A preliminar examination, made under the direction of Dr. L. O. Howard by Mr. C. H. T. Townsend, showed the enormous capacity for damage of the pest. Subsequent events have verified in every way the predictions that were made at that time, when the insect had not attracted any considerable amount of attention in the South. Since 1894 the boll weevil has extended its range annually from 40 to 70 miles, although in two instances the winter conditions have been such as to cause a decrease in the infested area. During the first ten years after its advent into this country the annual rate of spread was 5,640 square miles.
