Program Spotlights National Invasive Species Awareness Week By Vanessa Campoverde, Commercial Agriculture & Ornamentals Agent During the last week of February, we celebrated National Invasive Species Awareness Week (NISAW), where several events across the nation Mediterranean fruit fly Citrus greening disease (Huanlongbing) Asian longhorned beetle Giant African Land Snail (GALS), originally found in Miami-Dade County! were conducted to raise awareness and identify solutions to invasive species issues at local, state, tribal, regional and national levels. If you would like to know more about this initiative, go to: http://www.nisaw.org What is an invasive pest? The U.S. Department of Agriculture defines an invasive pest as an organism that is introduced into an area beyond its natural range and becomes a pest in the new environment (also referred as: alien, non-native or introduced pests). The damage done by invasive plants alone costs the U.S. an estimated $34.7 billion a year. An invasive pest does not occur naturally in a specific area and therefore may not have any natural enemies resulting in no natural control and a strong chance for economic or environmental harm. How do invasive pests spread? There are a few ways pests enter the U.S. and are able to cross state lines: by "hitch-hiking" on vehicles, fruits, plants, seeds or animals when travelers enter the U.S. or travel within states. when travelers bring prohibited fruits, plants, seeds, animals or other items back from other states or foreign countries. What are some of the top invasive pest threats in the U.S.? about invasive pests? When pests affect our local agriculture or resources, then we all suffer from lack of local food sources and prices will rise, causing more damage to native species and to our home economy. Giant African Land Snails GALS were initially found only in Miami-Dade County, but since last year, they have been found in our neighbor Broward County. Invasive pests don’t know boundaries, so we always have to be on the lookout for them. More information and the map of the current GALS distribution can be found here: http://www.freshfromflorida.com/ Divisions-Offices/Plant-Industry/Pests-Diseases/ Giant-African-Land-Snail.

The imported fire ant 2 National Nutrition Month® 2015 By Monica Dawkins, EFNEP Agent National Nutrition Month® is a nutrition education and information campaign celebrated annually in Recipe: Florida Flatbread with Tomatoes and Sweet Peppers March by the Academy of Nutrition and Dietetics. Initiated in 1973, “National Nutrition Week” was originally only a week, but became a month-long observance in 1980 in response to growing public interest in nutrition. The campaign focuses attention on the importance of making informed food choices and developing sound eating and physical activity habits. Each March and throughout the year, the Academy encourages everyone to return to the basics of healthy eating by adopting a healthy lifestyle focused on consuming fewer calories, making informed food choices and getting daily exercise. This year’s theme “Bite into a Healthy Lifestyle,” focuses on helping people create a healthy eating pattern and physical activity plan. By adopting these goals, this year’s theme strives to help people manage their weight successfully and reduce their risk of chronic disease while promoting general health. Your Own Private Nutrition Month Learning the facts about nutrition is a good step to celebrate National Nutrition Month and eat healthy all year long!

Burden (2012) reported that in the United States demand for jalapeño and other hot peppers increases every year as the popularity of ethnic cuisine increases. California and New Mexico produce most of the hot peppers grown in the United States, but many Florida farmers grow hot peppers as a niche crop (Ozores -Hampton and McAvoy, 2014). Trays with the jalapeño seedlings and plant in a pot with a tensiometer As world population continues to grow, resulting in less space for agriculture but greater food demands, we must try to increase the amount of food we can produce in a given space. One practice that might offer increased yield for a Cages in the field and four pots inside the Pearl cage at TREC given amount of area is the use of different shade cloths. Recently, colored shade cloth designed specifically for manipulating plant development and growth has became available. Stamps (2009) discussed the effect of this technique on the microclimate, vegetative growth, vegetative quality and fruit quality and yield. Plant response to different colors has been documented by Presented below are some preliminary data from this on-going study.

Ask anyone who gets to spend time either the Bay. on or near the water, and I’m sure that they will share in that experience. Biscayne Bay is the lifeblood of Miami and visitations to and use of the Bay contributes significantly to our local economy. This is because compared to other Florida waters, Biscayne Bay is characterized by very low concentrations of nutrients and pollutants and has excellent water clarity. The clean water is responsible for the fantastic views and allowing recreational experiences such as fishing, diving and boating. While most people know that the Bay is protected either federally or by the state as a National Park, State Aquatic Preserve, or a State critical wildlife area, the majority of Biscayne Bay is also an Outstanding Florida Water (OFW). Although Biscayne Bay remains relatively healthy, natural and human-induced events can negatively impact the Bay’s water quality. During the past decade, three such events have occurred in Biscayne Bay. These events were: These algal bloom events, unprecedented in their scale or duration, resulted in impacts to over 10,000 acres of bay bottom. While the exact causes of these blooms remain unknown, they indicate a diminished ability by the Bay to handle occasional negative inputs. Biscayne Bay is suspected of nearing a “tipping point” for water quality and health. Map of the algal bloom areas by year Algal blooms are not new to the headlines. Algal blooms in the Great Lakes have been so extreme that they have impacted the availability of local drinking water. Locally, the Indian River Lagoon has suffered record numbers of dolphins and manatees mortality as a result of algal blooms. Luckily for us, the health and status of Biscayne Bay is not as critical as in other areas; however we 1. A phytoplankton bloom that started in 2005 need to heed these warning signs.

People can tend to make the mistake that mastery equals perfection, but actually mastery is an on-going process that is a beginning to perfection. Zig Ziglar once stated, “You do not have to be great to start, but you have to start to be great.” In other words, mastery begins when young people put forth an effort to accomplish an objective. It may not be beautiful in the beginning, but with effort, passion, and encouragement, it can turn out magnificent. “Yes.” (Truthfully, I had a hard time identifying the thorax but the kid explained it to me beautifully.) “Does it have an abdomen?” “Yes!” “Six legs?” “Yes!” “Well, Sonny, then you created an insect!” The Branches 4-H member felt better. He walked away with a euphoric sense of accomplishment. I too felt great in giving the young man guidance and confidence in his creation. One of the four elements of positive youth I commend the youth development program at Branches in giving youth the opportunity to be great! These young ladies and gentlemen are brilliant and excited about learning. Their enthusiasm actually gets me pumped up about life and I am happy that Branches is a part of the UF/IFAS Miami-Dade County Extension 4-H Youth Development Family! Be on the Lookout: Argentine Tegus By Jake Edwards, Florida Fish and Wildlife Conservative Commission Wildlife Impact Management, Non Native Field Operations Argentine black and white tegus (Salvator merianae) are a species of lizard native to South America that have been introduced to Florida. Tegus are black and white in color with banding along the tail and can reach up to four feet in length. Tegu lizard populations are currently being assessed by the Florida Fish and Wildlife Commission (FWC) in several areas throughout the state through trapping and surveying projects. Thought to be separate introductions, Hillsborough counties. The Miami-Dade population is centered in the Florida City/ Homestead area. Wildlife officials are currently trying to gather more information about their populations in Miami-Dade County. Tegus are omnivores, eating both vegetation and other animals and show a special fondness for eggs.

The undergraduate students from Gainesville spent all of their spring break traveling and visiting University of Florida/IFAS Extension and Research Centers across the state to learn about what UF/IFAS Extension agents do as they provide research based solutions to citizens at a personal and professional level. These students didn’t travel to the always sunny Miami-Dade County for fun, but instead traveled for an education and some insight on research and extension work. “We are very thrilled to share our unique jobs within the University of Florida Extension system to enthusiastic students”, said UF/IFAS Commercial Horticulture agent Vanessa Campoverde. Ms. Campoverde welcomed the students and shared with these future professionals the nature of what UF/IFAS Extension agents do in South Florida. Students learned about the economic impact of the agriculture industries including vegetables, tropical fruit and ornamental plants. They also learned about outreach community events, 9 (Continued from page 9) research and diagnostic work at the UF/IFAS Tropical Research Education Center (TREC), and collaborative work with many state specialists and organizations.
