Facts about Wildlife Diseases: Hemorrhagic Fever in White-Tailed Deer

deer

The viruses that cause hemorrhagic disease (HD) in deer do not cause illness in people, but they are a growing problem. HD is the most important viral disease of white-tailed deer in the United States. Large outbreaks have occurred in the northern Midwest and western United States. In Florida outbreaks are fewer and less severe in populations of wild white-tailed deer than are outbreaks among wild deer in other areas of the United States, but farm-raised deer in the state are proving vulnerable to epizootic hemorrhagic disease virus: one of the viruses that cause HD. This 6-page fact sheet written by Katherine A. Sayler, Charlotte Dow, and Samantha M. Wisely and published by the Department of Wildlife Ecology and Conservation describes best management techniques for outbreaks of HD in farm-raised deer. It includes strategies for best supportive care for sick animals, diagnostics, and integrated pest management to control biting midges that spread the viruses that cause HD, because the best way to manage HD is to prevent it.

Landowner Cost-Share Incentives and Payments for Ecosystem Services: A Comparison of Key Program Features

Florida forests

Landowners who conduct land management activities that protect environmental benefits may be eligible for several types of financial assistance from the government, but not all incentive strategies are the same. This 4-page fact sheet written by Melissa M. Kreye, Elizabeth Pienaar, and Raoul K. Boughton and published by the Department of Wildlife Ecology and Conservation compares traditional cost-share programs offered to landowners through federal agencies and a new type of market-based incentive program called payments for ecosystem services (PES). The information inside can help private landowners understand the advantages and limitations of both approaches and guide decision-makers in designing effective future conservation incentive programs.

Using the Ecosystem Services Approach to Advance Conservation Efforts on Private Lands

deer

Decision-makers in Florida have shown increased interest in using the Ecosystem Services (ES) approach to reward ecosystem conservation efforts on private lands. For example, payments for ecosystem services (PES) strategies have been effective in motivating landowners to conserve ecosystems on their land. Some landowners may find a better understanding of the ES approach to be useful when deciding to participate in a PES program. This 5-page fact sheet written by Melissa M. Kreye, Elizabeth Pienaar, Raoul K. Boughton, and Lindsey Wiggins and published by Department of Wildlife Ecology and Conservation will provide landowners, Extension agents, government and agency leaders, and other stakeholders with a better understanding of how ES are classified, the different ways ES can be valued, how quantifying ES values can help support conservation efforts on private lands in Florida, and a few of the challenges inherent in using the ES approach.

Guide to Olive Tree Nutrition in Florida

A healthy Arbequina olive grove in Volusia County, Florida.A burgeoning olive industry already exists in the southeastern United States, but research and Extension information regarding olive fertilization recommendations in Florida is limited. While there are data and recommendations for olive from the University of California, the University of Georgia (UGA), and other institutions around the world, there are no data from which we can derive Florida-specific recommendations. This 6-page fact sheet uses many of the existing recommendations for mature, high-density, and traditional grove spacing as guidelines until data specific to Florida production are generated. It discusses leaf tissue sampling procedures, leaf tissue sufficiency ranges, nitrogen fertility, phosphorus and potassium fertility, boron, concerns for olive production in Florida, and other resources for olive production in the state.

florida flower thrips

The Florida flower thrips is a known pest of blueberry but its status in other crops is unclear. Florida flower thrips transmits Tomato spotted wilt virus and possibly other tospoviruses. This species is primarily a flower feeder, so most damage would be expected on the flower or fruit. Learn to identify the Florida flower thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.

Zika is a mosquito-transmitted virus that has recently spread to the Americas. Zika virus (ZIKV) was discovered in 1946 in Africa where it was isolated from a Rhesus monkey in the Zika forest of Uganda. In 2007, a disease outbreak occurred on the Yap islands in Micronesia, and in 2013, an outbreak occurred in French Polynesia. In 2015, a large outbreak occurred in Brazil, and ZIKV has since spread through the Americas. As of April 18, 2016, 15 counties in the state of Florida had reported travel-associated Zika cases. This seven-page fact sheet provides an overview of ZIKV, including its incidence and distribution, transmission and symptoms, and the connection between zika virus and infant microcephaly. This article also explains the biology and identification of the mosquito that vectors the virus with a focus on how to manage the vector using inspection, larviciding, adulticiding, monitoring, and personal protective equipment.

Pest Identification Guide: Chilli thrips Scirtothrips dorsalis Hood

chilli thrips
Chilli thrips transmits the ilarvirus Tobacco streak virus (TSV) and the tospoviruses Groundnut bud necrosis virus (GBNV), Groundnut chlorotic fan-spot virus (GCSFV), and Groundnut yellow spot virus (GYSV). This species primarily feeds on young, tender foliage. Feeding on foliage may result in silvering leading to necrosis, leaf curl (upward), distortion, and defoliation. Feeding on the fruit may cause scarring, discoloration, and the formation of corky texture on the fruit. Learn to identify the chilli thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.

Metsulfuron-methyl, also known as MSM, is an herbicide that is used to control broadleaf weeds and certain grass weeds. It provides effective control of some of the most problematic turfgrass weeds, such as wild garlic, Florida betony, dollar weed, and small Virginia buttonweed. Metsulfuron-methyl is absorbed by plant foliage, so if landscape plants come into contact with the spray or drift they can be injured. This four-page fact sheet describes the potential problems with metsulfuron herbicides, the areas most subsceptible to damage, how to diagnose injury, and how to reduce damage.

Cucurbit downy mildew is a major disase that affects over 40 species of cucurbits, like watermelon, muskmelon, cucumber, squash, and pumpkin. The classic sign of the disease is the presence of dark sporangia, a structure that holds developing spores, on the underside of infected leaves. As the disease progresses, it may lead to large necrotic areas that cause defoliation and a reduction of yield and marketable fruit. This nine-page fact sheet describes the symptoms and signs, epidemiology and disease cycle, host range and pathotypes, and the ways to manage cucurbit downy mildew. Written by Mason J. Newark, Mathews L. Paret, Nicholas S. Dufault, Pamela D. Roberts, Shouan Zhang, Gary E. Vallad, Josh Freeman, and Gene McAvoy, and published by the Plant Pathology Department.
