Anagyrus pseudococci Girault (Insecta: Hymenoptera: Encyrtidae)
Anagyrus pseudococci is an economically important biological control agent commonly used against the vine mealybug (which infests wine grapes) and the citrus mealybug. It is a solitary, internal parasitoid and lays one egg per host, with the larva developing inside the host’s body. The wasps may be commercially reared and distributed inside mummies, and they will emerge within 1-5 days after delivery. Application involves placing a bottle containing the mummies in a dry spot of the crop and allowing the adults to emerge. This 5-page fact sheet was written by Theresa Chormanski and Ronald D.

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

Contaminants in the Urban Environment: Perfluoroalkyl Substances
Perfluoroalkyl substances (PFASs) or perfluorochemicals (PFCs) are the most widespread and persistent manmade chemicals on earth. Common products that contain PFASs are Teflon pans, non-stick cookware, rain/waterproof jackets (like Gore-Tex), fire-fighting foams, food packaging, carpets, and furniture fabrics. PFASs stay in the environment for a long period of time, which means they can accumulate in organisms to levels that cause harmful effects. This 9-page fact sheet discusses the occurrence, use, exposure, and potential harmful effects of PFASs to humans and the environment, and suggests ways to reduce your exposure to PFSAs.

Managing Conflicts with Wildlife: Living with Snakes
Snakes provide numerous benefits to people and to the environment, by controlling rat and mice populations in the environment, for example. Or in the laboratory, where pygmy rattlesnake venom research helped develop medicine to thin the blood of heart attack patients. Most snakes are secretive and rarely bother people, but there are situations where some snakes can become dangerous. In this 4-page fact sheet, we present some facts about snakes, describe dangers they may cause, and provide suggestions on how to cope with these dangers. Written by Holly K. Ober, Steve Johnson, and William M. Giuliano, and published by the UF Department of Wildlife Ecology and Conservation, November 2014. (Photo: Steve Johnson)

Tawny Crazy Ant (previously known as Caribbean crazy ant) Nylanderia (formerly Paratrechina) fulva (Mayr) (Insecta: Hymenoptera: Formicidae: Formicinae)
Nylanderia fulva is part of a group of ants referred to as “crazy ants” due to their quick and erratic movements. It has been reported from 27 counties of Florida and 27 counties of Texas, as well as from Louisiana, Mississippi, Alabama and Georgia. Huge number of workers in infested areas can make human activities uncomfortable and difficult. They can infest sidewalks, buildings and gardens, and damage phone lines, air conditioning units and computers. They have killed honey bee larvae and used the hives as their nests, and are even displacing red imported fire ants where the two populations overlap in Texas.

Fiddlewood leafroller, seagrape moth (suggested common names) Epicorsia oedipodalis (Guenée, 1854) (Lepidoptera: Ditrysia: Pyraloidea: Pyralidae: Pyraustinae)
These caterpillars roll up leaves of the host plants and use the rolled leaves as larval retreats and locations for pupal cocoons. Although these leaf-eating pests do no permanent damage, they can completely defoliate fiddlewood, a Florida native that can form a large shrub or small tree. The shrub simply puts out a new flush of leaves. The larvae themselves are valuable food source for baby birds during the spring dry season in Florida.

Squash Vine Borer Melittia cucurbitae (Harris) (Insecta: Lepidoptera: Sesiidae)
Squash vine borer is a moth species that is active during the day (diurnal). The larvae complete their growth and development on wild and domesticated species of the genus Cucurbita. Once only considered a nuisance to commercial growers, with the expansion of cucurbit production in the United States over the last decade, the squash vine borer has become a pest of economic importance.

Wellsina Mite Hemicheyletia wellsina (De Leon) (Arachnida: Acari: Cheyletidae)
This predatory mite was recently discovered in an unsprayed greenhouse at the University of Florida, Gainesville, living on Phalaenopsis and Dendrobium orchids, and assumed to be feeding on orchid pests such as spider mites, tenuipalpid mites, and mealybugs that were present on the orchids. Because there was no published information on this species as a natural enemy of orchid pests, colonies were initiated here to study its biology, maintained on two-spotted spider mite prey. Hemicheyletia wellsina does not appear likely to be an effective natural enemy in agricultural crops as an introduced predator, but could be beneficial in natural biological control in natural ecosystems, where pest densities are lower.

Io Moth Automeris io (Fabricius) (Insecta: Lepidoptera: Saturniidae)
The beautiful Io moth is one of our most recognizable moths, because of its prominent hind wing eyespots. The attractive Io moth caterpillar is also well-known because of its painful sting. But like many of the other saturniid moths, is less common now in parts of its range. With the exception of Cape Cod and some of the Massachusetts islands, it is now rare in New England where it was once common, and its populations have declined in most of the Gulf States since the 1970s.

Robbing Behavior in Honey Bees
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.

Economic Impacts of Highway Beautification in Florida
The Florida Department of Transportation is allocated money every year for highway landscaping projects. They make driving more pleasant and are better for the environment, but do they attract private investment and contribute to the economy? This study, commissioned by the FDOT, finds that the average annual economic impacts of highway beautification expenditures in Florida during 2008–2013 amounted to $46 million in output impacts and $28 million in value-added impacts.

Conservation Subdivision: Post-construction Phase: Policy Directions and the Importance of Assessing Stakeholder Opinions
Simply designating open space in a development is not enough to provide long-term protection for a variety of wildlife. New policies need to be developed that encourage developers of conservation developments to adopt long-term management practices that support biodiversity conservation. This 5-page fact sheet discusses policy options that could be used to support conservation management practices and reports on a survey of Colorado landowners who have created conservation developments and their opinions about a policy option to support the implementation of management practices.
