Tawny Crazy Ant

Tawny crazy ant female worker

As of 2012, tawny crazy ants have invested 24 counties in Florida, parts of southeast Texas, and other areas of the southeastern U.S. The tawny crazy ant is considered a series pest. This species infests buildings and greenhouses, attacks crops, domestic animals, honeybee hives, displaces native ant species, and disrupts electrical equipment. This 3-page fact sheet covers the tawny crazy ant’s distribution, description, colonies, feeding habits, and pest status and control. Written by S. K. Hill, R. W. Baldwin, R. M. Pereira, and P. G. Koehler, and published by the UF Department of Entomology and Nematology, October 2013.

Can Calcium Propionate Help Maintain Calcium Concentrations and Prevent Metritis in Dairy Cows with Dystocia?

VM223 blurb photo

Studies have suggested that giving dairy cows supplemental calcium may reduce the incidence of metritis. This study tested this hypothesis with cows at the UF Dairy Unit and found that calcium supplements actually did not benefit postpartum health and are not recommended as means of metritis prevention. This 3-page fact sheet was written by Klibs N. Galvao, Mauricio Benzaquen, and Carlos A. Risco, and published by the UF Department of Veterinary Medicine?Large Animal Clinical Sciences, June 2015.

Florida Carpenter Ants

Figure 1.  Adult carpenter ant major worker. Credit: www.tamu.eduCarpenter ants are in the genus Camponotus, in which up to over 900 species have been described worldwide. They get their common name, “carpenter ant,” because some species excavate nests in wood. Carpenter ants are sometimes called bulldog ants or bull ants. However, not all species in the genus Camponotus are true carpenter ants because some nest in preformed cavities or in soil. This 5-page fact sheet was original published as part of Pests in and around the Florida Home, and was written by R. J. Vazquez, P. G. Koehler, R. M. Pereira, J. Warner, and R. H.

African Honey Bee: What You Need to Know

Figure 1. Exposed African bee nest on a tree limb

African honey bees entered the United States in the early 1990s and have since spread throughout the Southwest and Southeast, including parts of Florida. Compared to European bees, African bees are highly aggressive when disturbed and are more likely to sting humans and animals.  This 6-page fact sheet covers the history and distribution of African honey bees in the Americas and explains how beekeepers and residents can manage their interactions with these bees. Written by H. Glenn Hall, Catherine Zettel-Nalen and James D. Ellis, and published by the UF Department of Entomology and Nematology, December 2014. http://edis.ifas.ufl.edu/mg113

Managing Conflicts with Wildlife: Living with Panthers

Figure 1. A Florida pantherPanthers help maintain populations of some native species and control nuisance species such as wild hogs. They are generally secretive and rarely bother people, but there are rare situations where panthers can become dangerous or damaging. In this 4-page fact sheet, we present some facts about panthers, describe dangers and problems they may cause, and provide suggestions on how to cope with these issues. Written by William M. Giuliano, Holly K. Ober, Lauren Watine, Raoul Boughton, Eric Hellgren, Darrell Land, and Mark Lotz, and published by the UF Department of Wildlife Ecology and Conservation, December 2014.

Seafood Knowledge, Perceptions, and Use Patterns in Florida: Findings from a 2013 Survey of Florida Residents

Figure 1

Over the past few years, consumers have begun to pay more attention to the nutritional benefits, sustainability, and environment impact of consuming seafood. However, media coverage of these concerns may leave consumers confused and uncertain about how they should incorporate seafood into their diets. In 2013, a survey was conducted to better understand Florida seafood consumer preferences, perceptions, and concerns. This 4-page fact sheet explains the survey’s findings and how they might help Extension deliver effective seafood-based education to Florida residents.

Observation Bee Hives

The use of observation bee hives continues to interest a variety of people. This is not surprising. The observation hive is one of the primary research and educational tools in apiculture. It is both educational and entertaining. Observation bee hives can be used to enhance public relations and marketing programs. But a great deal of time and energy is needed to set up a hive and keep it going. Maintenance can be expensive and time consuming, especially if the hive is to be used as a permanent display for the general public. This 3-page fact sheet provides sources for building observation hives and tips for maintenance. Written by David Hall, James D. Ellis, and Malcolm Sanford, and published by the UF Department of Entomology and Nematology, March 2015. (UF/IFAS photo by Tyler Jones)

Figure 1. Level of importance of Florida issues reported by Floridians who use irrigation in the home landscape (N = 1063)

To better promote water-conservation practices among homeowners who irrigate their landscaping, Extension professionals must first have a clear understanding of this target audience’s habits, beliefs, and needs. This 10-page fact sheet recommends that Extension professionals analyze their audiences through several factors, including their interest in water conservation and knowledge of water issues and laws.

Perceptions of Florida-Friendly Landscapes: Linking Visual Quality and Environmental Health through Landscape Codes

plant beds with natural forms that require less trimming.
Early efforts to promote Florida-Friendly landscapes emphasized the use of drought-tolerant plants, which created a negative association with a visually unappealing landscape. This has hampered the promotion of FFL yards and the adoption by homeowner associations. But recently many homeowners are rethinking their landscape maintenance and plant choices and HOAs are considering promoting environmentally friendly landscapes but express uncertainty about recommending FFL because of the need to maintain visual quality. We conducted a study to address both groups’ concerns and help develop FFL-oriented landscape codes that meet both groups’ needs. This 7-page fact sheet was written by Gail Hansen, Laura Warner, Paul Monaghan, Emily Ott, Tim Fogarty, Claire Lewis, and Esen Momol, and published by the UF Department of Environmental Horticulture, April 2015.

Thrips in Florida Strawberry Crops

Figure 2. Thrips damage to strawberry. Credit: H. A. SmithStrawberries grown in Florida are attacked by several pests, including flower thrips. Western flower thrips and common blossom thrips (both invasive) can cause damage to strawberries in Florida; but, while the native Florida flower thrips is commonly found in strawberry blossoms, it hasn’t been established that it can cause economic damage to strawberry. This 9-page fact sheet describes thrips damage, characteristics to distinguish among the three species, and methods of control. Written by Jeff D. Cluever, Hugh A. Smith, Joe E.
