Resumen:
Alternate feeding hosts of adult Anthonomus grandis were studied in Tamaulipas. Ingested pollen grains were from 14 identified plant families. The most commonly represented families were Compositae (29.9%), Leguminosae (14.6%), Malvaceae (5.3%), Gramineae (0.6%), and Fagaceae (0.6%). Mean survival times of boll weevils were significantly greater when fed either pure pollen mixtures, Gossypium hirsutum buds (cotton), Opuntia lindheimeri (Cactaceae) flowers, or Abutilon hypolecum (Malvaceae) than controls (water only). Polyphagous pollen feeding behavior may be an important survival strategy of the boll weevil in the absence of reproductive hosts, especially in tropical habitats where adult boll weevils may be active throughout the year. -from Authors
