Weevils: More Than Just Pests
The term "gorgojo," translated as weevil or snout beetle, refers to a vast and diverse group of beetles. This article explores different aspects of these creatures, from their classification and impact on agriculture to their controversial use in alternative medicine.
Considerations for Pets
- Weevils can infest stored food products like grains, potentially leading to infestation of pet food.
Scientific Classification and Nomenclature
- Common Name: Weevil, Snout Beetle (Gorgojo, Picudo)
- The term "gorgojo" commonly refers to beetles belonging to the family Curculionidae.
- Curculionidae is the most significant and diverse family within the superfamily Curculionoidea.
- Synonyms: picudo
Distribution and Habitat
- Weevils are found worldwide.
- One reference mentions a high concentration of different species in Madagascar, numbering almost 1,300 different types.
Ecological Role
- Many weevil species are considered pests of stored products, such as grains. Examples include the granary weevil (gorgojo del granero), rice weevil (gorgojo del arroz), and Angoumois grain moth.
- Pine weevils (gorgojos del pino) are bark beetles that attack pine forests, posing a threat to forestry.
Morphological Characteristics
- Weevils are generally small beetles, often with an elongated snout or rostrum.
- The wheat weevil (Sitophilus granarius) is described as 3 to 4 mm long and dark brown, almost black, with a glossy appearance.
- One reference mentions weevils of one centimeter long.
Interactions with Other Organisms

- The black vine weevil (Otiorhynchus sulcatus) is a common pest of garden plants and nurseries.
Quirky Facts
- In some alternative medicine practices ("coleoterapia"), live Chinese weevils (Ulomoides dermestoides) are ingested as a purported treatment for various diseases, including cancer, Parkinson's disease, and diabetes. This practice involves consuming an increasing number of live weevils daily.
- The text references a "chain of the weevil" ("cadena del gorgojo"), a solidarity network where weevils are given away, suggesting a social aspect to their use in alternative medicine.
