Wellsina Mite Hemicheyletia wellsina (De Leon) (Arachnida: Acari: Cheyletidae)

Figure 6. Adult Hemicheyletia wellsina (De Leon) (right) feeding on an adult female of the two-spotted spider mite Tetranychus urticae (Koch) (left) by grasping the front leg of the spider mite. Credit: Haleigh RayThis predatory mite was recently discovered in an unsprayed greenhouse at the University of Florida, Gainesville, living on Phalaenopsis and Dendrobium orchids, and assumed to be feeding on orchid pests such as spider mites, tenuipalpid mites, and mealybugs that were present on the orchids. Because there was no published information on this species as a natural enemy of orchid pests, colonies were initiated here to study its biology, maintained on two-spotted spider mite prey. Hemicheyletia wellsina does not appear likely to be an effective natural enemy in agricultural crops as an introduced predator, but could be beneficial in natural biological control in natural ecosystems, where pest densities are lower.

Io Moth Automeris io (Fabricius) (Insecta: Lepidoptera: Saturniidae)

Figure 1. Male Io moth, Automeris io (Fabricius). Credit: Donald W. Hall, UF/IFASThe beautiful Io moth is one of our most recognizable moths, because of its prominent hind wing eyespots. The attractive Io moth caterpillar is also well-known because of its painful sting. But like many of the other saturniid moths, is less common now in parts of its range. With the exception of Cape Cod and some of the Massachusetts islands, it is now rare in New England where it was once common, and its populations have declined in most of the Gulf States since the 1970s.

The Florida Panther: Past, Present, and Future

Figure 3. A kitten is administered dewormer during a den visit. Credit: Madelon van de Kerk Florida panther was presumed extinct by the early 1950s, but were rediscovered in 1973 by a survey team organized by the National Geographic Society. They were one of the first species to be added to the US endangered species list and are now the only population of North American puma that occurs east of Mississippi River. This 3-page fact sheet describes Florida panther research and management actions, the effects they have had on the population, and continuing challenges. Written by Madelon van de Kerk, David P.

Yellowmargined Leaf Beetle: A Pest of Cole Crops

igure 1. A young mustard plant being eaten by YMLB adults and larvae.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.

Habitat Requirements of the Florida Panther

UW390The Florida panther (Puma concolor coryi) was listed as endangered under the Endangered Species Act in 1967. Habitat loss and fragmentation are primary threats, driven by urban development and the conversion of rangelands to row crops, citrus production, and mining. This 3-page fact sheet focuses on which habitats are most important for conservation of the Florida panther. Written by Elizabeth F. Pienaar and Elena C. Rubino, and published by the UF Department of Wildlife Ecology and Conservation, October 2014. (Photo courtesy of the Florida Fish and Wildlife Conservation Commission.)

The Extension Services-237 Report: Everything You Need to Know

4-H cloverThe Extension Services-237 (ES-237) is a report of the Cooperative Extension Service that consists of enrollment statistics for youth ages 5–18 participating in Extension youth programs and the volunteers providing service to these programs. Since partial funding for Extension youth programs is received through the USDA, each county and state must report each year on the race, gender, grade, and residence of each participant in these programs. In Florida, the report is completed by each UF/IFAS county Extension office each year using 4HOnline, then submitted to Florida 4-H state headquarters where they are compiled into a single state report and submitted to the National Institute of Food and Agriculture (NIFA) at the United States Department of Agriculture (USDA). This 6-page fact sheet was written by Ben Knowles and Tracy A. Tesdall, and published by the UF Department of 4-H Youth Development, October 2014.

Nutrient Management of Vegetable and Agronomic Row Crops Handbook

Florida vegetables and row cropsThrough the implementation of a series of targeted cultural practices discussed in this production guide, growers should be able to reconcile economic profitability and responsible use of water and fertilizer. Topics include: proper sampling practices and test interpretations; irrigation management methods and automation; use of alternate fertilizer materials to retain nutrients in the soil but allow adequate supply for crop uptake. Use of these BMPs ensures that adequate fertilizer rates may be achieved by combinations of UF/IFAS recommended base rates and supplemental fertilizer applications. This 199-page handbook was edited by Kelly T. Morgan, and published by the UF Department of Soil and Water Science, February 2015.

Bismarckia nobilis: Bismarck Palm

Figure 1. Bismarckia nobilis.The Bismarck palm is a native of Madagascar that grows to a height of 30 to 60 feet with a spread of 12 to 16 feet. The massive 4-foot-wide costapalmate leaves are typically silver-green in color, but a light olive-green-leaved variety also exists. The persistent leaf bases are split, creating an attractive pattern on the 15–18-inch-diameter trunks. The dark brown male and female inflorescences are produced on separate trees, with females developing olive-brown fruit about 1.5 inches in diameter. The bold texture and color and eventual great height of this species make a strong statement in any setting, but can be overpowering in small residential landscapes.

Robbing Behavior in Honey Bees

Figure 1. The colonies in this apiary are being equalized (i.e. populations are being made uniform). Having many colonies open at the same time caused the bees from the colonies to initiate a robbing frenzy.Western honey bee workers can invade and steal honey/nectar from other colonies or sugar/corn syrup from feeders used to deliver syrup to other colonies. This is called “robbing” behavior. Robbing behavior typically involves the collection of nectar and honey, but not pollen or brood. Some beekeepers report that robbing bees may steal wax or propolis from other hives, but there is not much data available on this occurrence. Robbing behavior can escalate quickly from just a few bees robbing other colonies to a massive frenzy of bees robbing many colonies in an apiary.
