Excerpt from A Preliminary Account of the Wheat and Rice Weevil in India The chief points which are uncertain or unknown in its history have been indicated, in the hope that some of those who take an interest in the matter may assist in obtaining the information which is wanted: as it is only from a most minute and accurate knowledge of its habits and peculiarities that reliable inferences can be drawn.

Book Description
Excerpt from The Rice Water-Weevil and Methods for Its Control Clean cultural management in dealing with the weevil as with other crop pests is advisable. By restricting the growth of the various grasses and other plants, particularly the Objectionable red variety of rice, which grow along and within canals, ditches, and water holes, much advantage could be derived toward the suppression of the breeding of the weevils on the uncultivated host plants. Drain age of bayous, Sinks, and water holes would doubtless be of great benefit for the control of the weevil alone. Leveling of the surface of fields that are to be planted in rice and plowing in such a manner as to avoid dead furrows as much as possi ble would obviate many of the depressions which on being deeply flooded conduce to a high infestation of the plants in such places.

Book Description
Excerpt from The Effects of Cathode-Ray Irradiation on the Rice Weevil in Wheat Differences in the effects between types of radiation have been reported in numerous references in the earlier literature. However, later workers, including Packard and Heilbrunn and Mazia, in Duggar (5) agree that the different types of radiation produce similar effects when comparable Energy inputs per unit of time and per unit of volume are absorbed, indicating an advantage of cathode rays in some applications. The major objective of the first test was to determine the effects of cathode-ray ir radiation on rice weevils infesting wheat. The initial series of tests, using an electron beam unit, was preliminary in nature. It was expected that the results would point the way to more intensive experiments and a practical method of insect control in stored wheat.

Book Description
Excerpt from Birds That Eat the Cotton Boll Weevil: A Report of Progress During the growing season of cotton the adult weevils are concealed the greater part of the time on the buds, or 'squares, ' where the enfold ing bracts afford almost complete protection from most of their enemies; this fact largely explains why comparatively few weevils are eaten by birds during the summer months. The amount of time they spend on the wing and the distance they fly from place to place are not well known, but it is only during the period of maximum infestation that any considerable proportion of the insects can be found in exposed situations. After the first hard frost, weevils begin to leave the cotton plants and seek sheltered places in which to hiber nate. During this period their numbers are materially reduced, but in favored seasons many weevils successfully pass the winter in their retreats. Rubbish piles about the borders of fields apparently furnish the most desirable hibernating quarters, and in such situations the weevils are exposed more or less to the attacks of ground-feeding birds. They are said to make use also of the hiding places afforded by the cotton and corn stalks which have been left standing. Investigations thus far made show that while fewer weevils are destroyed by birds in winter than in summer, the number of Species of birds that feed upon them in winter is somewhat greater. The birds which eat boll weevils in winter and spring and up to the time of the breeding season of the insects are more important economically than those which eat them in summer, for the reason that during the season of nonactivity of the weevils a relatively long period must elapse before they can make good the losses in their numbers, while during the breeding season weevils multiply with astonishing rapidity.
