Nombre: Myllocerus undatus Marshall
Animalia: Arthropoda: Insecta: Coleoptera: Curculionidae
Nombre común: a weevil of Asian origin
Myllocerus undatus was discovered in southern Florida in October, 2000. The infestation apparently encompasses an area of approximately 26 X 9 miles (~41 X 14 km). Although the potential impact as a pest is unknown, this insect has been observed on numerous hosts in Florida which suggests an extremely broad host range.
Preocupación: Aside from the original description (Faulk, 1916), there are virtually no reports of this insect in the literature. There is essentially no information available on this pest's biology. Its distribution was apparently previously limited to Sri Lanka, although a more extensive Asian distribution may exist.
Hospedantes: Host records in Florida include: lychee (Litchee chinensis), longan (Euphoria longana), mamey (Mammee sapota), areca palms (Dypis lutescens), hibiscus (Hiscus rosa-sinensis), Australian brush-cherry (Syzygium paniculatum), cocoplum (Chrysobalanus icaco), tropical almond (Terminalia catappa), crepe-myrtle (Lagerstroemia indica), akee (Blighia sapida), citrus (Citrus spp.), grapefruit (Citrus x paradisi), Hong Kong orchid tree (Bauhinia x blakeana), orchid tree (Bauhinia spp.), powderpuff (Calliandra haematocephala), Surinam cherry (Eugenia uniflora), orange jasmine (Murraya paniculata), calomondin (Citrafortunella microcarpa), and Turk's cap (Malvaviscus penduliflorus)
Asia (Sri Lanka), U.S.A. (recent infestation in Florida)

Adult feeding damage is most easily observed, manifested as marginal leaf notching or skeletonizing. Adult damage may be visible from a considerable distance. Larvae are presumed to be root feeders, although further biological data will be necessary to confirm this. Regarding surveys, there are reports that adults may fly to blacklight traps.
Myllocerus undatus is superficially similar to a weevil native to Florida, Artipus floridanus. A morphological comparison of these species can be viewed on Florida's DPI Pest Alert.
