Thrips Management Program for Horticultural Crops

Among the 5,500 (or more) well-described species of thrips worldwide, nearly 1% are known as economically important pests. Because these tiny pests can feed on multiple plants, their damage potential to nursery and greenhouse production is immense: thrips inflict millions of dollars loss every year. Thrips hide easily in tiny spaces, reproduce rapidly, and can survive in lots of climates. And they are invisibly small! Thrips infestations present a huge problem in the regional and international trade of plant materials and products, due to the quarantine risks and damage associated with several species in the order.

This 7-page fact sheet written by Vivek Kumar, Garima Kakkar, Cristi Palmer, Cindy L. McKenzie, and Lance S. Osborne and published by the UF Department of Entomology and Nematology presents a program to manage important thrips pests, including western flower thrips (Frankliniella occidentalis), chilli thrips (Scirtothrips dorsalis), weeping fig thrips (Gynaikothrips uzeli), gladiolus thrips (Thrips simplex), and privet thrips (Dendrothrips ornatus) known to damage several horticultural crops of economic importance in the United States. The publication will help growers take appropriate measures to minimize economic damage.

Protecting Florida Panthers by Protecting Domestic Animals: Building a "Panther-Proof" Pen

Florida panthers once ranged throughout most of the southeastern United States, but loss of habitat and efforts to eradicate panthers during the 1800s led to a large decline throughout much of their historic range. Florida panthers were listed as an endangered species in 1967 and have been federally protected by the US Endangered Species Act since 1973. For the most part, the role of panthers in the natural environment benefits people (they prey on burgeoning populations of white-tailed deer, raccoons, opossums, and feral hogs). Panthers do sometimes kill pets and livestock in rural and residential areas in southwest Florida, however, and some people believe that panther kills happen because panther populations have grown too large or are not well-managed. In fact, the panther population is dangerously small, and most of these losses can be attributed to poor management not of panthers but of pets and livestock. To maintain support for panther conservation, it is paramount that rural residents protect and secure their pets and livestock. This 3-page fact sheet written by Phillip D. Rodgers, Elizabeth F. Pienaar, Mark Lotz, and Darrell Land and published by the UF Department of Wildlife Ecology and Conservation explains how to make a locking, secure enclosure to protect livestock from panther predation–and protect the fragile panther, as well.

Florida's Bats: The Florida Bonneted Bat

The Florida bonneted bat is one of only two endangered species of bat in Florida and the state’s only endemic flying mammal (“endemic” means that it is found nowhere in the world but in Florida). With a 20-inch wingspan, it is Florida’s largest bat and the third largest of all 48 species of bats in the United States. The Florida bonneted bat was listed as federally endangered in 2013 because of concerns over habitat loss, degradation, and modification caused by humans. Additional concerns include the species’ small population size and restricted range, the small number of known colonies, their slow reproduction, and the relative isolation of separate populations of bonneted bats. This 2-page fact sheet written by Holly K. Ober, Terry Doonan, and Emily Evans, and published by the UF Department of Wildlife Ecology and Conservation explains how to differentiate Florida bonneted bats from velvety free-tailed bats and Brazilian free-tailed bats and explains what to do if you find one of these endangered bats.http://edis.ifas.ufl.edu/uw426

Keeping Bees in Florida

As of June 2016, there are over 4,000 registered beekeepers in the state of Florida and 440,000 managed colonies. According to the USDA, 2012 Florida beekeepers produced over 11 million pounds of honey. The average winter colony loss in Florida as reported by the Bee Informed Partnership Management Survey was the third lowest rate across the nation with only Hawaii and Texas reporting lower colony losses in that time period. This 4-page fact sheet written by Tomas A. Bustamante, Jamie D. Ellis, and Mary Bammer and published by the UF Department of Entomology and Nematology gives an overview of what makes Florida a unique state in which to keep honey bees. It explains the ins and outs of beekeeping in Florida, with descriptions of some of the hazards, a few of the important nectar-producing plants, special considerations for seasonal colony growth and management, and Florida beekeeping regulations.

Chalkbrood Recommendations

A pathogenic fungus called chalkbrood can turn infected larval honey bees into “mummies,” killing them and reducing their colony’s population and productivity. Florida’s subtropical climate may contribute to a greater incidence of the disease, which is common throughout the state. This 2-page fact sheet describing chalkbrood and listing some management strategies to control it was written by Malcolm T. Sanford, Cameron J. Jack, and Jamie Ellis, and published by the UF Department of Entomology and Nematology, December 2016.

What the 2012 Census of Agriculture Is Telling Us about Miami-Dade County

Agriculture is an important contributor to Florida’s economy. Only the tourism industry employs more Floridians. In 2012, agricultural output was estimated at $141.8 billion, accounting for 14.9% of the state’s gross domestic product, and providing employment for 20.8% of the state’s labor force. Monitoring the performance of the sector over time is therefore of critical importance to various stakeholders. This 8-page publication written by Edward Evans and published by the Food and Resource Economics Department focuses on the Agricultural Census data for Miami-Dade County and specifically examines trends over the 15-year period from 1997 to 2012 with the aim of highlighting some of the major trends occurring in the Miami-Dade County agricultural sector. In general, the data show that in spite of challenging times, the agricultural industry has remained important, contributing $604 million to the Florida economy in 2012.

Are Consumers Interested in Ornamental Plants That Benefit Pollinator Insects?

Population declines among bees, butterflies, and other pollinator insects are very worrying because 70% of the world’s food crop production depends upon these tiny insect workers. Fortunately, ninety million US households have yards, landscapes, or gardens that can enhance pollinator habitat and health. Consumers’ actions can drastically impact pollinator insects and even help them to recover. This 5-page fact sheet written by Hayk Khachatryan and Alicia Rihn and published by the UF Department of Food and Resource Economics, October 2016, describes a new UF/IFAS study of consumers’ actions and perceptions as they considered ornamental plants that benefit pollinators. It covers consumers’ current actions to aid pollinators, their interest in purchasing plants to help pollinators, and their perceptions about plant availability, and it describes strategies for merchants and producers to cater to consumer preferences for in-store communications/promotions and help them to find and purchase plants that aid pollinator insects.

Ecological Risk Assessment for Invasive Wildlife in Florida

Global trade and travel transport plants and animals from native ranges to new ecosystems. About 10 to 20% of nonnative (exotic, alien) species that arrive in new locales become invasive, meaning they are likely to harm the environment, economy, or public health. Preventing the introduction of invasive species is the most effective way to protect native biodiversity and ecosystem integrity. Once an invader begins to establish and spread, its control costs increase rapidly. Florida ports are the entry points for about half of the reptiles, arachnids, insects, and crustaceans imported into the United States. These arrivals, coupled with hospitable climate and habitats, have made Florida home to more invasive species than any other state but Hawaii. While it is too late to prevent the invasion of Burmese pythons and Argentine black and white tegus, we can act to prevent other potentially destructive species from establishing. This 6-page fact sheet written by Venetia Briggs-Gonzalez, Kyle Allen, Rebecca G. Harvey, and Frank J. Mazzotti and published by the Department of Wildlife Ecology and Conservation explains how to assess the risk that a given invasive species presents to the environment and how to develop and use risk-screening tools to reduce the harmful effects of invasions or, better yet, prevent them entirely.

Coral Reef Conservation Strategies for Everyone

Corals are small animals related to jellyfish. Large groups of these animals live together and form huge interconnected colonies called reefs. Coral reefs are some of the most diverse ecosystems on the planet; an essential habitat for a wide variety of animal and plant species. About 400 million people rely on coral reef fish as a source of protein; about 6 million people make a living by catching and selling coral reef fish and invertebrates; tourism activities like SCUBA diving and snorkeling provide revenue of US$9.6 billion per year; and reefs reduce wave energy by 97%, helping to protect 197 million people in coastal areas from beach erosion, wave energy, and flooding. Learn how you can help protect these fragile, essential ecosystems from threats in this 7-page fact sheet written by Kathryn E. Lohr and Joshua T. Patterson and published by the Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation.

Government Efforts to Protect Habitat for the Florida Panther on Private Lands

Endangered Florida panthers live and breed on state and federal lands in south Florida, but they are a wide-ranging species, and the habitat available to them on public lands is not enough for them to thrive and recover. The 2008 Panther Recovery Plan by the US Fish and Wildlife Service requires that habitat for the panther be conserved on both public and private lands throughout the state. Private rangelands in southwest and south central Florida provide important habitat and prey for the Florida panther. These lands also play a key role in conserving other native species like gopher tortoises, bob white quail, turkeys, deer, vultures, scrub jays, cranes, black bears, and bobcats. Unfortunately, these rangelands are under increasing development pressure as the human population in Florida continues to grow. Multiple policy approaches have been put in place by local, state, and federal governments to address habitat loss and secure natural resources in Florida for our panthers. This 5-page fact sheet written by Elizabeth F. Pienaar and Melissa M. Kreye and published by the Department of Wildlife Ecology and Conservation provides a brief overview of existing regulatory and voluntary approaches to help conserve the Florida panther on private lands.

Considerations for Building Climate-Based Species Distribution Models

Climate plays an important role in the distribution of species. A given species may adjust to new conditions in-place, move to new areas with suitable climates, or go extinct. Scientists and conservation practitioners use mathematical models to predict the effects of future climate change on wildlife and plan for a biodiverse future. This 8-page fact sheet written by David N. Bucklin, Mathieu Basille, Stephanie S. Romañach, Laura A. Brandt, Frank J. Mazzotti, and James I. Watling and published by the Department of Wildlife Ecology and Conservation explains how, with a better understanding of species distribution models, we can predict how species may respond to climate change. The models alone cannot tell us how a certain species will actually respond to changes in climate, but they can inform conservation planning that aims to allow species to both adapt in place and (for those that are able to) move to newly suitable areas. Such planning will likely minimize loss of biodiversity due to climate change.
