Dagger nematodes parasitize plants. They cause economic damage and death of host crops through feeding on the roots and by spreading viral mosaic and wilting diseases, but field studies have shown that some control measures targeting reduction in the population of dagger nematodes can be effective in controlling viral diseases in susceptible crops.

Australian cockroaches are the most common outdoor cockroach in southern Florida. Though they typically stay outdoors, Australian cockroaches may also venture inside and live among humans. This 4-page fact sheet covers the Australian cockroach’s distribution and habitat, biology, medical risks to humans, and management as a pest. Written by Shiyao Jiang and Phillip E. Kaufman, and published by the UF Department of Entomology and Nematology, April 2015.
Among the most destructive plant-parasitic nematodes to a wide range of plants, Belonolaimus longicaudatus damages plant roots. When the plants cannot take up water and nutrients from the soil, they become stunted, wilt, and with severe infestation, die. Florida is considered to be the point-of-origin for Belonolaimus longicaudatus and therefore this nematode exhibits a great deal of diversity in morphology, host preference, and genetics in our region.

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. Cave, and published by the UF Department of Entomology and Nematology, March 2015. (Photo: Kent M. Dane)
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.

The chicken mite affects egg-laying hens in many parts of the world, including Europe, Japan, China, and the United States. Although Dermanyssus gallinae affects birds in many regions, it is most prevalent in European countries, where egg industry losses are estimated at $177 million per year. It is a known vector for the St. Louis encephalitis virus, as well as other illnesses, such as fowl pox virus, Newcastle virus, and fowl cholera. In the United States, Dermanyssus gallinae is rarely found in caged-layer operations and is more commonly found in breeder farms. This 3-page fact sheet was written by Ethan Carter and Jennifer L.

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.

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 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.

Broad-headed bugs belong to a well-known but relatively small family of plant-feeding true bugs, usually seen feeding on the foliage and flowers of leguminous and graminaceous crops. Leptocorisa acuta (Thunberg) can be found on many crop plants in the family Poaceae (grasses), especially rice, and is a reported pest of economic significance in rice-producing countries like India, Australia, and China.

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.

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.

Ripiphoridae 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.

El árbol melaleuca es una planta leñosa invasiva, nativa de Australia, Nueva Guinea, y las Islas Salomón. La melaleuca, conocida también como el árbol de corteza de papel, cajeput, punk tree, o árbol de cepillo blanco, fue introducida en Florida al final del siglo 19 pero aparentemente no se naturalizó hasta el año 1906. La melaleuca fue sembrada extensivamente como un árbol ornamental, y eventualmente invadió los humedales con y sin bosques en el sur de Florida formando monocultivos densos.

Anopheles gambiae Giles is commonly called the African malaria mosquito because it is the most efficient vector of human malaria in the Afrotropical Region. They are considered to be one of the world’s most important human malaria vectors because of their susceptibility to the Plasmodium parasite, their preference for humans as a host, and their indoor-feeding behavior. Due to their short development time and their preference for developmental habitats near human dwellings, Anopheles gambiae are considered effective vectors of human malaria, as well as lymphatic filariasis (elephantiasis).
