Consumers' Response to "Neonic-Free" and Other Insect Pollinator Promotions on Ornamental Plants

Pollinator insects are essential to world food crop production, the economy, and the environment. Neonicotinoid (neonic) insecticides are facing intense backlash from environmental groups because the systemic protection they provide throughout the plant, including the pollen and nectar, may be injuring pollinator insects and causing their population decline. But many nursery and greenhouse growers use neonic-based pesticide control measures because they are effective, inexpensive, and cause less environmental damage than other insecticides. The increased publicity may influence consumer demand and preferences but very few studies have investigated consumer responses to neonic-free labels, and evidence suggests that many consumers have little knowledge or awareness of the issue. This 3-page fact sheet describes the results of a the study investigating how consumers’ awareness of neonic insecticides influenced their preferences and purchasing behavior for plants and exploring the marketing potential of using alternate pollinator promotions (besides neonic-free) in garden center retail outlets.

Hydrilla: Florida's Worst Submersed Weed

Hydrilla, which was originally introduced to the state as an aquarium plant, was intentionally planted in canals by aquarium plant dealers in the 1950s and quickly escaped cultivation. In addition to being one of the world’s worst aquatic weeds, the species is Florida’s most intensively managed submersed plant. Hydrilla is a federally listed noxious weed and a prohibited aquatic plant in Florida, making cultivation, sale, and possession of the species illegal. This 7-page fact sheet discusses the classification, characteristics, habitat, and management of hydrilla. Written by Lyn A. Gettys and Stephen F. Enloe, and published by the UF Agronomy Department, February 2016.

Biology, Control and Invasive Potential of Giant Reed (Arundo donax L.) in Florida

Arundo donax (L.), also known as giant reed, is a tall, fast-growing, bamboo-like grass that under ideal conditions can reach a height of up to 30 feet and a stem diameter up to 1.5 inches. Giant reed is invasive and difficult to control and has caused economic losses in California, Nevada, Utah, Arizona, New Mexico, and Texas. This species was introduced to Florida over 100 years ago and is currently naturalized in at least 26 of the 67 Florida counties. So far giant reed has not proved problematic in Florida, but recent permitting of its planting for bioenergy feed stock may increase the risk that it could naturalize into plant communities in Florida and other southeastern states and potentially cause economic losses as well as harm to native species and habitats. This 5-page fact sheet written by Pat Minogue and Seth Wright and published by the School of Forest Resources and Conservation describes the biology of this species and explains some strategies for its control.

The Green-Spore Poison Parasol Mushroom,Chlorophyllum molybdites

The “false parasol” or “green-spored parasol” mushroom (Chlorophyllum molybdites) is a poisonous mushroom that is the most common cause of mushroom poisoning in the United States. This mushroom is widely distributed throughout Florida and the southeastern United States. It commonly creates a complete or incomplete “fairy ring” in lawns, grassy areas, and open woods. When mature, the green-spored parasol mushroom has a large cap, a ring around its stem, and a greenish color on the underside of its gills. This four-page fact sheet describes the morphology, ecology, and distribution of the green-spored mushroom as well as its toxicology and how to treat poisoning from this mushroom. Written by Lisbeth Espinoza and Matthew E. Smith, and published by the Plant Pathology department.

Rancher Perceptions of the Coyote in Florida

Throughout the continental United States and large portions of Canada and Central America, changes people make to the landscape such as the clearing of forested land and the extermination of larger predators like gray and red wolves have made the environment perfect for the adaptive coyote. Coyotes have rapidly taken advantage of these environmental shifts and expanded into new areas, now including all 67 counties in Florida and even Key Largo. Each year more people in Florida catch a glimpse of a coyote crossing a road or running across open fields, or notice coyote scat along a hiking trail–and farmers and ranchers are seeing signs of coyotes on their farms.

As coyotes become a fixture of the Florida landscape, potential grows for conflict with humans. Coyotes are in Florida to stay, and understanding the agricultural community’s perception of their influence on livestock and wildlife is important to developing effective policies for coyote management. This 4-page fact sheet written by Raoul K. Boughton, Bethany Wight, and Martin B. Main and published by the Wildlife Ecology and Conservation Department provides results of ongoing statewide surveys of ranchers in Florida regarding the influence of coyotes on their operations.

Zika, a Mosquito-Transmitted Virus

Zika is a mosquito-transmitted virus that has spread broadly in tropical regions and caused epidemics, especially in the past 8 to 9 years. In its native range in West Africa and Uganda, the Zika virus stays in the forest for the most part, and human infections are considered incidental and medically inconsequential. In 2015, however, Zika became a larger concern when a strain of the virus traced to outbreaks in French Polynesia emerged in northeastern Brazil. This strain provoked alarm because of increased incidence of microcephaly in babies born to Zika-infected mothers. Local transmission, mainly by the yellow fever mosquito Aedes aegypti, has now been documented in most tropical countries of the Americas but has not yet been detected in the continental United States. This 7-page fact sheet written by L. P. Lounibos, B. W. Alto, N. D. Burkett-Cadena, C. C. Lord, C. T. Smartt, C. R. Connelly, and J. R. Rey and published by the Department of Entomology and Nematology describes the Zika microbe, its mosquito hosts, and the disease it causes. A history of the virus and its migration are included, along with some details about the virus in the state of Florida and preventative measures people can take to avoid infection. The best way to avoid contracting Zika (and other mosquito-borne diseases) is not to get bitten in the first place. Take precautions to avoid mosquito bites.

El Zika, un Virus Transmitido por Mosquitos

Zika es un virus transmitido por mosquitos que se ha esparcido recientemente en regiones tropicales y ha causado epidemias, especialmente durante los últimos 8 o 9 años. En su ámbito nativo en África Occidental y Uganda, el virus se mantiene en los bosques, circulando entre mosquitos que viven en huecos de árboles y primates arbóreos; las infecciones de humanos se consideran incidentales y de poca importancia médica. Una cepa del virus que se implicó en brotes en Polinesia Francesa emergió en el Norte de Brasil en el 2015 y causó gran consternación debido a la alta incidencia de microcefalia en bebes nacidos de madres que fueron infectadas con el virus durante la gestación. Transmisión local, principalmente por el mosquito de la fiebre amarilla Aedes aegypti, ha sido documentada en la mayoría de los países tropicales de las Américas, pero aún no se ha detectado en Los Estados Unidos Continentales. Los síntomas de la infección incluyen, salpullido, dolor de cabeza, fiebre, dolor muscular y en las coyunturas, conjuntivitis, y malestar general.

The Social Organization of Honey Bees

A honey bee colony is a superorganism, which means that together its members function like a single animal. Bees within a colony work together like the cells in a human body. They warm the colony in the winter by vibrating their wings to generate heat and cool it in the summer by ferrying in droplets of water and fanning air over them. Worker bees fan air into and out of the colony entrance in distinct inhalations and exhalations. Colonies reproduce by swarming to create new daughter colonies that in turn thermoregulate, breathe, and reproduce just as a single autonomous animal does. In three pages this fact sheet explains the intricate caste system and age-based division of labor that allows colonies of humankind’s best-loved pollinators to function and thrive. Written by Ashley N. Mortensen, Bryan Smith, and James D. Ellis and published by the Entomology and Nematology Department.
