Water and Nutrient Management Guidelines for Greenhouse Hydroponic Vegetable Production in Florida

Hydroponically grown plants
Many small farms are implementing greenhouse hydroponic systems. Perhaps the most challenging aspect of crop management for smaller growers is the control of water and nutrient delivery in a soilless media system. This six-page fact sheet focuses on relatively inexpensive strategies to help small growers know both when to start irrigation events and how long to run a single event when growing in soilless media.

Pest Identification Guide: An Introduction to Thrips

Dorsal view of an adult common blossom thrips, Frankliniella schultzei Trybom.Tiny insects called thrips are difficult to see with the unaided eye but cause very obvious and sometimes ruinous damage to the flowers, buds, and fruit of many important crops. This two-page guide asks and answers the key thrips questions that allow growers to distinguish between chilli thrips, common blossom thrips, and Western flower thrips to more effectively battle against these destructive pests. What does it look like? What is its life cycle? Where is it found? What type of damage does it cause? And, most importantly, who are its natural enemies? Use this guide to help you identify thrips so that you can take effective steps to control them and limit the damage they cause.

The Social Organization of Honey Bees

Honey bee castes: a. drone (male), b. queen (reproductive female), and c. worker (non-reproductive female).
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.

Small Flock Poultry Nutrition

Inadequate poultry nutrition results in substandard growth rates as well as decreased egg production and weight. In order to express the genetic potential for which they were selected, meat- and egg-type birds must receive the correct amounts of nutrients and energy through properly formulated rations. This 4-page fact sheet examines the roles of water, carbohydrates, proteins and amino acids, lipids (fats and oils), vitamins, minerals, and feed additives in poultry growth and development. It also emphasizes the importance of providing suitable feeds to birds of different ages and discusses common feeding mistakes. Written by Michael A. Davis, published by the UF Department of Animal Sciences, and reviewed and revised August 2015. This fact sheet is a major revision of “Small Poultry Flock Nutrition,” written by B. L. Damron and D. R. Sloan, April 1998.

Observation Bee Hives

The use of observation bee hives continues to interest a variety of people. This is not surprising. The observation hive is one of the primary research and educational tools in apiculture. It is both educational and entertaining. Observation bee hives can be used to enhance public relations and marketing programs. But a great deal of time and energy is needed to set up a hive and keep it going. Maintenance can be expensive and time consuming, especially if the hive is to be used as a permanent display for the general public. This 3-page fact sheet provides sources for building observation hives and tips for maintenance. Written by David Hall, James D. Ellis, and Malcolm Sanford, and published by the UF Department of Entomology and Nematology, March 2015. (UF/IFAS photo by Tyler Jones)

Zombie Fly (suggested common name) Apocephalus borealis Brues (Insecta: Diptera: Phoridae)

Figure 4. Adult female Apocephalus borealis.The zombie fly is primarily a parasitoid of bumble bees and wasps in North America. In 2012, Dr. John Hafernik and his colleagus at San Francisco State University discovered that Apocephalus borealis also parasitizes honey bees. Parasitized honey bees show zombie-like behavior by leaving their hives at night and are often attracted to nearby lights where they show disoriented behavior and die in a few hours.

Health Benefits and Medicinal Value of Honey

Figure 2. HoneyHoney has been used for medicinal purposes for thousands of years. It is rich in sugars such as glucose and fructose, but it also contains small amounts of vitamins, minerals, amino acids, and antioxidants such as phenolic acids and flavonoids. These nutrients help to make honey a unique, natural health product. Its market niche as a health product is growing, and current research supports the potential of honey as a medicinal product. This 3-page fact sheet describes health aspects of honey deriving from the floral source and color, beneficial compounds, anti-microbial properties and anti-inflammatory properties.

Robbing Behavior in Honey Bees

Figure 1. The colonies in this apiary are being equalized (i.e. populations are being made uniform). Having many colonies open at the same time caused the bees from the colonies to initiate a robbing frenzy.Western honey bee workers can invade and steal honey/nectar from other colonies or sugar/corn syrup from feeders used to deliver syrup to other colonies. This is called “robbing” behavior. Robbing behavior typically involves the collection of nectar and honey, but not pollen or brood. Some beekeepers report that robbing bees may steal wax or propolis from other hives, but there is not much data available on this occurrence. Robbing behavior can escalate quickly from just a few bees robbing other colonies to a massive frenzy of bees robbing many colonies in an apiary.

Wedge-Shaped Beetles (suggested common name) Ripiphorus spp. (Insecta: Coleoptera: Ripiphoridae)

Figure 1. Adult specimen of Macrosiagon HentzRipiphoridae are a family of unusual parasitic beetles that are thought to be related to tumbling flower beetles and blister beetles. They parasitize bees and wasps, roaches, and wood-boring beetles, but specific hosts for many ripiphorid species are unknown. Their secretive life cycle makes an assessment of their economic and ecological impact very difficult. Additional research is necessary to determine the abundance and impact of Ripiphorus species.

Over the past 20 years, school districts in all 50 states have joined the F2S program and are purchasing items from local farmers. Recent requirements for more fruit and vegetables in the National School Lunch Programs have made the F2S program more popular than ever. The University of Florida is committed to the Farm to School program and is working closely with the Florida Department of Agriculture and Consumer Services to connect farmers to schools.
