The Pantomorus cervinus, commonly known as the Fuller’s rose weevil or citrus root weevil, is a species of weevil in the family Curculionidae. It is considered a pest due to its impact on a wide variety of plants, particularly in agricultural settings. Pantomorus cervinus is polyphagous, meaning it feeds on a wide range of host plants. It is particularly known for attacking citrus trees, roses, and other ornamental and agricultural plants.

Diet

  • Adults: Primarily herbivorous, feeding on leaves, buds and tender shoots of many different plants. They are particularly well known for feeding on ornamental and fruit plants.

  • Larvae: Live in the soil, where they feed on plant roots.

  • The species has a broad host range and can occur on citrus, grapes, roses, strawberries, beans and numerous ornamental plants.

Range

  • Naupactus godmani is a broad-nosed weevil (Curculionidae: Entiminae: Naupactini) native to the Americas.

  • It occurs in Mexico, Central America and parts of South America, as well as areas where it has been introduced through the movement of plants.

  • The species is compatible with the warm climate of Guerrero and the Zihuatanejo region.

  • Around Zihuatanejo, it is occasional to fairly common, particularly in gardens, cultivated areas and vegetation surrounding fruit trees and ornamental plants.

Habitat

  • Found in tropical dry forest, woodland, gardens, orchards, agricultural areas, nurseries and disturbed vegetation.

  • Adults are often found on leaves at night, while during the day they may hide in vegetation, leaf litter or sheltered areas.

  • Larvae remain underground around the roots of host plants, where they can be difficult to detect.

Size

  • Adult length: approximately 8–12 mm (0.31–0.47 in).

  • Body robust and broadly oval, with a short, broad rostrum.

  • Usually brown, greyish-brown or mottled, with a covering of small scales that gives the beetle a somewhat dusty appearance.

  • The elytra are rounded and often show subtle longitudinal ridges and darker or lighter patches.
