The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most widely distributed and destructive pest of rice in the United States. This 4-page fact sheet written by Matthew T. VanWeelden and Ron Cherry and published by the Department of Entomology and Nematology provides a description of the rice water weevil, its distribution in the state of Florida, methodology for scouting, and options for managing this pest in commercial rice fields.
The tea shot-hole borer is an Asian ambrosia beetle introduced to Florida in the early 2000s. In Florida it does not have any known economic impact, but it is a serious pest of tea around the world and is one of the few ambrosia beetles that can infest healthy plants. The tea shot hole borer has a symbiotic relationships with the ambrosia fungus Fusarium ambrosium (Gadd & Loos), which is also a weak plant pathogen. This 4-page fact sheet includes diagnosis section with guidance for avoiding misidentification.

Black turpentine beetles bore into the inner bark of stressed or injured pines, where they breed and feed on phloem tissue. Adults are strongly attracted to volatile pine odors and readily breed in fresh stumps. In typical forests, infestations do not exhibit the rapid and devastating expansion characteristic of the closely related southern pine beetle, but in stands where stress conditions are frequent or persistent, black turpentine beetle can become a chronic pest and cause significant mortality over an extended period of time. Historically, black turpentine beetle has been a major pest of pines wounded or treated with herbicides in naval stores production. During the 1950s, black turpentine beetle damaged 37 million board feet of timber and contributed to the financial collapse of turpentine farms. This 5-page fact sheet was written by Albert E. Mayfield, John L. Foltz and Jiri Hulcr, and published by the UF Department of Entomology and Nematology, June 2015. (Photo credit Adam Black and Jiri Hulcr, UF/IFAS)
Xyleborus affinis is one of the most widespread and common ambrosia beetles in the world. It is also very common in Florida. Like other ambrosia beetles, it bores tunnels into the xylem of weakened, cut or injured trees and farms gardens of symbiotic fungus for food. Females lay eggs in the fungus-lined galleries and larvae feed exclusively on the fungi. Recent studies have shown that Xyleborus affinis can vector the fungus responsible for laurel wilt disease, which is lethal to numerous species of trees in the Lauraceae family.

El árbol melaleuca es una planta leñosa invasiva, nativa de Australia, Nueva Guinea, y las Islas Salomón. La melaleuca, conocida también como el árbol de corteza de papel, cajeput, punk tree, o árbol de cepillo blanco, fue introducida en Florida al final del siglo 19 pero aparentemente no se naturalizó hasta el año 1906. La melaleuca fue sembrada extensivamente como un árbol ornamental, y eventualmente invadió los humedales con y sin bosques en el sur de Florida formando monocultivos densos. This 5-page fact sheet is the Spanish language version of Melaleuca Snout Beetle, Melaleuca Weevil (unofficial common names), Oxyops vitiosa (Pascoe) (Insecta: Coleoptera: Curculionidae), written by J.P. Cuda, S.A. Wineriter, G.R. Buckingham, T.D. Center, and K.T. Gioeli, and published by the UF Department of Entomology and Nematology, December 2014.
Bagous affinis Hustache is a semi-aquatic weevil that feeds on the aquatic invasive plant Hydrilla verticillata (L.f.) Royle. The larvae of the weevil mine hydrilla tubers, and the adults feed on the submerged stems and leaves. The weevil was discovered during surveys for biological control agents for hydrilla in Pakistan in 1980 and was first introduced to the U.S. in Florida from India in 1987. This 5-page fact sheet was written by Emma Weeks, and published by the UF Department of Entomology and Nematology, June 2014.
Bagous hydrillae O’Brien is a semi-aquatic weevil that feeds on the aquatic invasive weed Hydrilla verticillata (L.f.) Royle. Larvae of the weevil mine hydrilla stems and the adults feed on the stems and submerged leaves. This weevil was discovered during overseas surveys for biological control agents for hydrilla during the 1980s and was first introduced to the U.S. in Florida in 1991 after extensive host-specificity testing. This 5-page fact sheet was written by Emma Weeks, Jim Cuda, and Michael J. Grodowitz, and published by the UF Department of Entomology and Nematology, June 2014.
Myllocerus undecimpustulatus undatus Marshall, the Sri Lankan weevil, is a plant pest with a wide range of hosts. This weevil spread from Sri Lanka into India and then Pakistan where many subspecies of Myllocerus undecimpustulatus Faust are considered pests of more than 20 crops. In the United States, the Sri Lankan weevil was first identified on Citrus sp. in Pompano Beach a city in Broward County Florida. Three specimens were identified by Dr. Charles W. O’Brien, first as Myllocerus undecimpustulatus, a species native to southern India, and then again as Myllocerus undatus Marshall native to Sri Lanka, finally as Myllocerus undecimpustulatus undatus Marshall to show its status as a subspecies.

Sometimes an insect pest attacking crops in places as far away as Indonesia or Ethiopia can be very important to us here in Florida. One such insect is the coffee berry borer, Hypothenemus hampei Ferrari (Coleoptera: Curculionidae: Scolytinae), a tiny (1.5 mm) bark beetle that originated in the highlands of central Africa. It would probably remain one of the many inconspicuous little beetles in the tropics, if not for the choice of its host: seeds of several Coffea species. This 3-page fact sheet was written by Jiri Hulcr, and published by the UF Department of School of Forest Resources and Conservation, October 2013.
The granulate ambrosia beetle is a minute ambrosia beetle of Asian origin that was first detected near Charleston, South Carolina. It can become abundant in urban, agricultural, and forested areas and has been reported as a pest of nursery stock and young trees in the Old World tropics and of peach trees in South Carolina. It is a potentially serious pest of ornamentals and fruit trees and is reported to be able to infest most trees and some shrubs (azalea), except for conifers.

Mizell, and published by the UF Department of Entomology and Nematology, March 2011.
