The yellowmargined leaf beetle is a pest of cole or cruciferous crops that is native to South America. Since first reported in Mobile, Alabama, in 1947, the beetle has spread throughout the Gulf Coast from Texas to Florida and up into Georgia and North Carolina. It has also been reported from Illinois and California. Not considered a major pest in conventionally grown cruciferous crops because it is susceptible to a wide range of insecticides, it poses a significant threat to the growing organic industry in the southeastern United States. It is a particular problem on Asian greens such as mizuna, mibuna, and napa cabbage, as well as on other high-value cruciferous crops like turnip, mustard, and watercress. This 4-page fact sheet was written by Elena M. Rhodes and and Oscar E. Liburd, and published by the UF Department of Entomology and Nematology, September 2014.
Spotted cucumber beetle is a major agricultural pest of North America. Another name for the spotted cucumber beetle is “southern corn rootworm”. Many Diabrotica species cause damage to field crops, especially corn, making these beetles a major agricultural concern. Because of the subterranean nature of their larvae, these insects are hard and expensive to control. This 6-page fact sheet was written by Harsimran Kaur Gill, Gaurav Goyal, and Jennifer Gillett-Kaufman, and published by the UF Department of Entomology and Nematology, September 2013.
Tropical soda apple is a prickly shrub native to South America that is a major problem in pastures and conservation areas. So a multi-agency program supported the rearing, distribution, and release of more than 250,000 tropical soda apple leaf beetles across Florida from 2003 to 2011. This 4-page fact sheet was written by Rodrigo Diaz, William A. Overholt, Ken Hibbard, and Julio Medal, and published by the UF Department of Entomology and Nematology, January 2013.
This leaf feeding beetle was recently introduced into Florida from China for biological control of air potato. This 4-page fact sheet provides information on the distribution, appearance, life cycle, host range and importance of the beetle. Written by Entomology and Nematology, and published by the UF Department of Ted D. Center and William A. Overholt, January 2013.
Alligatorweed is an aquatic weed native to South America that began threatening Florida’s waterways in the early 1900s. Alligatorweed flea beetles kill the plant by destroying its stored food and interfering with photosynthesis by removing leaf tissue. This insect has been an extremely effective biological control agent in coastal regions of the southeastern United States. This 3-page fact sheet was written by Ted D. Center, James P. Cuda, Michael J. Grodowitz, and published by the UF Department of Entomology and Nematology, October 2012.
The cottonwood leaf beetle is one of the most economically-important pests of managed cottonwood, aspen, and some poplar and willow species. Often it is a severe pest of urban ornamental trees. This leaf feeder has several generations each year, may cause extensive leaf loss, and can consequently reduce stem volume up to 70%. This 6-page fact sheet was written by Amelio A. Chi and Russell F. Mizell III, and published by the UF Department of Entomology and Nematology, June 2012.
