“…A. Gray (Gaines, 1934;Walker, 1959;Lukefahr & Martin, 1962;Jones et al, 1991) contribute toward egg production and larval development. Endocarps of oranges, grapefruit, and prickly pear cactus, and to a lesser extent, stalks of sugarcane, Saccharum spp., can, on average, support adult boll weevils from ≈20 days (sugarcane stalk) to ≈110 days (orange endocarp), and in terms of individual weevils, longevity can last as long as 253 days (on orange endocarp) (Showler & Abrigo, 2007).…”

“…(Malvaceae) (Hedin et al, 1973). Although the boll weevil's preferred reproductive hosts are species of Gossypium (Cross et al, 1975;Rummel & Summy, 1997;Showler & Abrigo, 2007), it is known to reproduce in the flower buds of other malvaceous plants (Gaines, 1934;Walker, 1959;Lukefahr & Martin, 1962;Jones et al, 1991), and it feeds on both pollen and non-pollen plant material (Benedict et al, 1991;Jones et al, 1992Jones et al, , 1993Hardee et al, 1999;Showler & Abrigo, 2007).…”

The capacities of the rind (i.e., the developing calyx and petals of squares; and the outer casing, or husk, of bolls) and the internal reproductive portion of cotton, Gossypium hirsutum L. (Malvaceae), squares of three sizes, and bolls of three ages to influence adult female boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), longevity and egg production were evaluated in laboratory bioassays. While feeding on the reproductive portion of squares was expected to support adult boll weevils for considerable periods of time (e.g., medium square reproductive portion: ≈185 days), feeding on rinds also resulted in substantial longevity (e.g., medium square rind: ≈120 days). As anticipated, feeding on the reproductive portion of squares resulted in formation of chorionated eggs in mated females, but a diet comprised exclusively of rinds, particularly from large squares, was associated with gravidity and high fecundity relative to rinds of young and mature bolls. The reproductive portion and rind of post‐bloom and young bolls as sources of food resulted in limited gravidity while mature bolls were not associated with any egg formation. These findings further our understanding of how boll weevils feed on different parts of the cotton plant and how those parts as food sources are related to the biology and ecology of the boll weevil.

“…Initially, it was thought that adult boll weevils only foraged on Gossypieae taxa (Gaines, 1934;Szumkowski, 1953;1954;Walker, 1959;Stoner, 1968;Cross et al, 1975). Research over the past 100 years has shown that adult weevils utilize pollen from various species including non-malvaceous taxa (Gaines, 1934;Szumkowski, 1953;1954;Stoner, 1968;Cross et al, 1975;Cate and Skinner, 1978;Rummel et al, 1978;Parrott et al, 1989, Hardee et al, 1999.…”

Cotton pollen is thought to exist in the gut of boll weevils for at least 24 hours. Because finding whole or broken cotton pollen grains are valuable clues in determining when boll weevils were living in cotton, the retention of cotton pollen in the gut of the weevil was examined. Boll weevils were fed cotton buds, cotton flowers, and water for five days, then they were placed into cleaned cages without any food. However they were allowed to drink water freely. Weevils were examined at 0, 24, 48, 72, 96, and 120 hours after the buds and flowers were removed. One hundred weevils were dissected at each time interval, and each gut was placed onto a glass slide. Light microscopy was used to determine the presence or absence of cotton pollen. More weevils (63%) at 0 hours contained pollen than weevils at any other interval. Whole pollen grains were not found in weevils after 24 hours. The 120 hour interval contained a single weevil with pollen. In the laboratory test, whole cotton pollen grains indicated that feeding on cotton occurred within 24 hours. When only halves and fragments of pollen were found, cotton feeding occurred 48-120 hours earlier. Additionally, when six or more cotton pollen grains were found in a weevil, it had fed on cotton within 24 hours. This information narrows the boll weevil dispersal times and distances from cotton fields and overwintering areas.
