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.

The Food Safety Modernization Act (FSMA) Preventive Controls for Animal Food
The Food Safety Modernization Act (FSMA) was signed into law in January of 2011 and is considered the most sweeping reform of food safety regulations in 70 years. The human food regulations were composed first and, with significant input from industry, academia, and consumer groups as well as other agencies, were then modified to better suit animal food production. In Florida, these new regulations apply to facilities that manufacture, process, pack, or hold food or food ingredients for animals. These facilities may include pet food manufacturers, renderers, ethanol distillers, feed mills, distributors, and others. The primary goal of these regulations is to ensure safe food for the animals, people who handle the feed, and people who consume the final animal products. This 3-page fact sheet discusses requirements, facilities that will most likely be expected to be in compliance, deadlines, development of a food safety plan, and preventive controls qualified individuals. Written by Jason M. Scheffler and Chad Carr, and published by the UF Department of Animal Sciences, 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.
