Root-knot nematodes are widespread and are pests of almost all major crops. Damage can be seen as galls or knot-like swellings produced along plant roots. Cover crops are used to manage nematodes because these microscopic roundworms can move only very short distances on their own and will starve without suitable host plants. This 6-page fact sheet describes several common cover crops that can be used for nematode management. Written by Harsimran K. Gill and Robert McSorley , and published by the UF Department of Entomology and Nematology, July 2011.

Integrated Pest Management (IPM) of the Caribbean Crazy Ant, Nylanderia (=Paratrechina) pubens (Forel) (ENY2006/IN889)
Incidents of Caribbean crazy ant infestations are on the rise! These highly active ants are
annoying to residents and pets. And, they can cause short circuits and power outages if they infest electrical equipment. Learn how to identify and apply the principles of integrated pest management (IPM) to deal with these difficult pests in this 4-page fact sheet written by Dawn Calibeo and Faith Oi and published by the UF Department of Entomology and Nematology, July 2011.

Recommendations for Management of Whiteflies, Whitefly-transmitted viruses, and Insecticide Resistance for Production of Cucurbit Crops in Florida (EENY478/IN871)
Until recently, squash has been the only cucurbit crop seriously affected by the B biotype of the sweetpotato whitefly, also known as the silverleaf whitefly, because of the silverleaf disorder induced by feeding of the immature stages (nymphs). However, three viruses transmitted by the whitefly have been identified in watermelon, muskmelon, and squash in Florida since 2004, making whitefly management a priority for most cucurbits. This 8-page fact sheet details the current UF/IFAS recommendations for managing whitefly-transmitted viruses and for delaying the development of resistance to insecticides in the whitefly vector. Published by the UF Department of Entomology and Nematology, July 2011.

Terrestrial Slugs of Florida (Mollusca: Stylommatophora: Veronicellidae, Phylomycidae, Agrolimacidae and Limacidae) (EENY494/IN891)
Most slugs are hermaphroditic, possessing both male and female sex organs. This makes slugs particularly dangerous as invaders because even a single individual that escapes detection can establish a population in a new environment through self-fertilization. This 11-page fact sheet discusses the slug situation in Florida, including problems with slug identification and taxonomy, as well as the behavior, ecology, and management of slugs. Written by John L. Capinera and Jodi White and published by the UF Department of Entomology and Nematology , June 2011.

Giant Whip Scorpion Mastigoproctus giganteus giganteus (Lucas, 1835) (Arachnida: Thelyphonida (=Uropygi): Thelyphonidae) (EENY493/IN890)
To encounter a giant whip scorpion for the first time can be an alarming experience! What seems like a miniature monster from a horror movie is really a fairly benign creature. While called a scorpion, this arachnid has neither the venom-filled stinger found in scorpions nor the venomous bite found in some spiders. This 4-page fact sheet was written by W.H. Kern Jr. and R.E. Mitchell, and published by the UF Department of Entomology and Nematology, May 2011.

Spotted Wing Drosophila Drosophila suzukii (Matsumura) (Insecta: Diptera: Drosophilidae) (EENY492/IN887)
Most Drosophila flies are associated with rotten or over-ripened fruits and are nuisance pests. However, a few species such as the spotted wing drosophila, D. suzukii (Matsumura), can infest un-ripened fruits and are of economic significance. First detected within the continental United States in August 2008, D. suzukii has become a serious threat to fruit crops. This 6-page fact sheet was written by Rajinder S. Mann and Lukasz L. Stelinski, and published by the UF Department of Entomology and Nematology, May 2011.

Redbay Ambrosia Beetle Xyleborus glabratus Eichhoff (Insecta: Coleoptera: Curculionidae: Scolytinae) (EENY491/IN886)
Ambrosia beetles are wood-degrading insects that live in nutritional symbiosis with ambrosia fungi. Usually we consider ambrosia beetles beneficial because they accelerate the decay of dead trees, which is important for nutrient cycling in healthy forests. However, the redbay ambrosia beetle and its fungal symbiont transmit the causal pathogen of laurel wilt disease among plants in the Laurel family (Lauraceae). They are considered a “very high risk” invasive disease pest complex having potential equal to that of Dutch elm disease or chestnut blight. Laurel wilt is a relatively new disease and much is still unknown about how it will impact the flora of North America. This 7-page fact sheet highlights what we do know about this important new pest. Written by Rajinder Mann, Jiri Hulcr, Jorge Peña, and Lukasz Stelinski, and published by the UF Department of Entomology and Nematology, May 2011.

Predatory Stink Bug, Alcaeorrhynchus grandis (Dallas) (Hemiptera: Pentatomidae) (EENY165/IN322)
Sometimes called the giant strong-nosed stink bug, this very large (20 mm) predatory stink bug occurs in several row crops and preys on other insects, especially lepidopterous larvae. The stages in the life cycle are presented here so that they can be identified in the field. This 3-page fact sheet was written by David B. Richman and Frank W. Mead, and published by the UF Department of Entomology and Nematology, March 2011.

Eye Gnats, Grass Flies, Eye Flies, Fruit Flies Liohippelates spp. (Insecta: Diptera: Chloropidae) (EENY485/IN884)
High concentrations of eye gnats are common in areas that have loose sandy soils, especially in the southern United States, and are a great nuisance to humans and animals in rural towns as well as agricultural, recreational, and tourist areas. While they do not bite, they can transmit several diseases to humans and livestock, including human acute conjunctivitis (pink eye). This 6-page fact sheet focuses broadly on two species that are common in the southeastern region of the United States are L. pusio and L. bishoppi (Sabrosky).

Horn Fly Haematobia irritans irritans (Linnaeus) (Insecta: Diptera: Muscidae) (EENY490/IN885)
The horn fly is one of the most economically important pests of cattle worldwide. Just in the United States, hundreds of millions of dollars in losses are attributed to the horn fly annually, while additional millions are spent annually on insecticides to reduce horn fly numbers.

Milkweed Assassin Bug (Suggested Common Name) Zelus longipes Linnaeus (Insecta: Hemiptera: Reduviidae) (EENY489/IN883)
Commonly called the milkweed assassin bug, because it closely resembles the milkweed bug, it is also known as the longlegged assassin bug and the Zelus assassin bug. Members of the genus Zelus belong to the subfamily Harpactorinae and are diurnal in nature. They are generalist predators feeding on a wide range of soft-bodied prey in garden and fields, such as mosquitoes, flies, earthworms, cucumber beetles, and caterpillars (fall armyworm, rootworm, etc.) Learn more in this 7-page fact sheet written by Megha Kalsi and Dakshina R.

Granulate Ambrosia Beetle, Xylosandrus crassiusculus (Motschulsky) (Insecta: Coleoptera: Curculionidae: Scolytinae) (EENY131/IN288)
The granulate ambrosia beetle is a minute ambrosia beetle of Asian origin that was first detected near Charleston, South Carolina. It can become abundant in urban, agricultural, and forested areas and has been reported as a pest of nursery stock and young trees in the Old World tropics and of peach trees in South Carolina. It is a potentially serious pest of ornamentals and fruit trees and is reported to be able to infest most trees and some shrubs (azalea), except for conifers.
