Book Description
Excerpt from Report on Investigations of the Pink, Bollworm of Cotton in Mexico Bolls and squares were used, but the squares were found more satisfactory. The food with the young larvae was placed in vials plugged with cotton. The pieces of bolls would become discolored, decomposed, and unsuitable for food in one or two days, while a square would remain in good condition several days and the larva could be examined daily with less disturbance. Wire cages were also used over small potted plants and cotton plants in the experimental plat to check the laboratory results. The pupae were removed to glass vials with a piece of damp cotton in the bottom to provide the necessary humidity.
