Various types of weevils and different foods were used In the different lots but the method Of procedure was identical for all. Large, weevil-proof screen cages were used.

Excerpt from The Boll Weevil Complex in Arizona The infestations produced from cotton-reared thurberia weevils indicated that the weevil did not adapt itself to cotton during the 10 years. At the end Of each season all the, cotton plants were cut and placed in large cages to provide weevils the following year. In the 12 years no infestations were found before weevil releases were made, indicating that no weevils survived naturally until squares and bolls were available for feeding and oviposition.

Excerpt from Relation of Drought to Weevil Resistance in Cotton In order to take full advantage Of other measures for combating the weevils, the relation of drought to the behavior of the growing plants must be considered, no less than the direct effect of the drought upon the weevils.
