Cultivos en asocio, diversidad de cultivos y manejo integrado de plagas (ENY862S/IN932)

Figure 5. El valle de Almolonga, Guatemala, en donde muchos cultivos hortícolas son producidos en pequeñas parcelas. La diversidad de cultivos puede reducir la acumulación de ciertas especies. Créditos: Hugh Smith El cultivo en asocio (o cultivo intercalado) es una práctica en donde se siembran diversos cultivos en un mismo campo. Adicionalmente plantas que no son cultivos, tales como las malezas, cultivos rastreros o de cobertura, así como plantas del hábitat, se pueden combinar en el espacio y tiempo para influir en el número de plagas o artrópodos benéficos en un cultivo principal.

Stable Fly (Dog Fly) Control (ENY267/IG133)

Figure 1. Stable fly.The stable fly is a blood-sucking filth fly of considerable importance to people, pets, livestock, and the tourist industry in Florida. Filth flies, including stable flies, exploit habitats and food sources created by human activities, such as farming. Stable flies primarily attack animals for a blood meal, but in the absence of an animal host, they will bite people. This 4-page fact sheet was written by P. E. Kaufman and E. N. I. Weeks, and published by the UF Department of Entomology and Nematology, August 2012.

Figure 3. Adult mealybug female. The citrus mealybug is a common pest of citrus primarily in greenhouses, and of several ornamental plants in Florida. It has been recognized as a difficult to control pest in Europe since 1813, where it is called the greenhouse mealybug and in the United States since 1879.

Polyphemus Moth Antheraea polyphemus (Cramer) (Insecta: Lepidoptera: Saturniidae: Saturniinae) (EENY531/IN945)

Figure 1. Adult male polyphemus moth, Antheraea polyphemus (Cramer dorsal view).The polyphemus moth, Antheraea polyphemus (Cramer), is one of our largest and most beautiful silk moths. It is named after Polyphemus, the giant cyclops from Greek mythology who had a single large, round eye in the middle of his forehead. The name is because of the large eyespots in the middle of the moth’s hind wings. This 9-page fact sheet was written by Donald W.

Entomopathogenic Nematodes (Nematoda: Rhabditida: families Steinernematidae and Heterorhabditidae) (EENY530/IN944)

Figure 3. Generalized life cycle of entomopathogenic nematodes.Entomopathogenic nematodes are soft bodied, non-segmented roundworms that are obligate or sometimes facultative parasites of insects. They occur naturally in soil environments and locate their host in response to carbon dioxide, vibration, and other chemical cues. They fit nicely into integrated pest management programs because they are nontoxic to humans, specific to their target pests, and can be applied with standard pesticide equipment.

Cottonwood Leaf Beetle Chrysomela scripta Fabricius (Insecta: Coleoptera: Chrysomelidae: Chrysomela) (EENY519/IN936)

Figure 10. Life cycle of the cottonwood leaf beetle, Chrysomela scripta Fabricius.The cottonwood leaf beetle is one of the most economically-important pests of managed cottonwood, aspen, and some poplar and willow species. Often it is a severe pest of urban ornamental trees. This leaf feeder has several generations each year, may cause extensive leaf loss, and can consequently reduce stem volume up to 70%.

Embalses Costeros Para el Control de los Mosquitos (ENY648S/IN193)

Figure 6b. Recobro de la vegetación en el embalse IRC #12.Los embalses costeros utilizados en Florida para el control de los mosquitos son marismas o manglares con un dique periférico que permite inundar el área durante la temporada de cría de mosquitos. Desde entonces, investigaciones científicas han demostrado que el embalsamiento puede causar serios impactos ambientales en las marismas, manglares y esteros colindantes. Hoy en día, se ha devuelto una hidrología más natural a más de 1,300 ha de marismas y manglares embalsados y se han eliminado más de 70 km de diques. De las 16,185 ha originales de marismas embalsadas en la laguna Indian River, se han restaurado de alguna manera más de 12,600 ha, ya sea por reconexión, brechas en los diques, o restauración de las orillas.

Mosquito Control Impoundments (ENY648S/IN192)

Figure 5. The Banana River project.A mosquito control impoundment is a salt marsh or mangrove forest with an earthen dike around the perimeter that allows the area to be artificially flooded during the mosquito breeding season. Since the seventies, research has shown that impounding can have severe environmental impacts on the marshes and the adjoining estuary. So, over 12,600 hectares of the original 16,185 of impoundments have been rehabilitated in some fashion. This 6-page fact sheet was written by Jorge R. Rey and C.

A Stink Bug Euschistus quadrator Rolston (Insecta: Hemiptera: Pentatomidae) (EENY523/IN937)

Figure 1. Dorsal view of Euschistus quadrator Rolston; adult male (left) and female (right), a stink bug.Euschistus quadrator, like other stink bugs, is highly polyphagous. It is found on weeds such as clover, vetch and other legumes. It feeds on many different crops, though it is primarily found on cotton, soybeans and corn. Stink bugs cause injury to various fruits and vegetables by feeding, resulting in significant quality and yield loss. They have piercing-sucking mouthparts and most feed primarily on fruits and seeds. This 5-page fact sheet was written by Sara A. Brennan, Joseph Eger, and Oscar E. Liburd, and published by the UF Department of Entomology and Nematology, June 2012.

Figure 1. Adult male Doryctobracon areolatus (Szépligeti), a parasitoid wasp of Anastrepha spp.Doryctobracon areolatus was introduced into Florida and the Dominican Republic for control of the Caribbean fruit fly and the West Indian fruit fly. In its native habitats, parasitism of fruit flies in certain fruit can reach more than 80%. Mean parasitism of Caribbean fruit fly following original establishment in Florida was around 40%.

Western Leaffooted Bug Leptoglossus zonatus (Dallas) (Insecta: Hemiptera: Coreidae) (EENY517/IN935)

Figure 1. Adult western leaffooted bugs, Leptoglossus zonatus (Dallas), on citrus fruit.Leptoglossus zonatus feeds on the satsuma mandarin by inserting its piercing-sucking mouthparts in the fruit and releasing a toxic substance. It transmits a trypanosomatid plant pathogen similar to the one that causes Chagas’ disease and sleeping sickness in humans, but that is only pathogenic to plants.

Tawny Emperor butterfly Asterocampa clyton (Boisduval & LeConte) (Insecta: Lepidoptera: Nymphalidae: Apaturinae) (EENY528/IN933)

Figure 4. An adult male tawny emperor, Asterocampa clyton (Boisduval & Leconte), with wings open. The tawny emperor is a medium sized, non-descript butterfly that is common in riparian forests, but is also found in dry woods and suburbs. Larvae that develop in fall overwinter in small groups in a hibernaculum constructed by tying leaves together with silk so it stays on the tree throughout the winter.

Bean Plataspid: Megacopta cribraria (Fabricius) (Insecta: Hemiptera: Heteroptera: Plataspidae) (EENY527/IN939)

Figure 2. Adult bean plataspids, Megacopta cribraria (Fabricius), on a building in Georgia, USA. Notice the enlarged, truncated scutellum covering the wings.Also known as the kudzu bug, lablab bug, and globular stink bug, the bean plantaspid is native to Asia, where it is not an agricultural pest. But in the U. S., it is reported as a pest of soybean in Georgia and South Carolina. Adults from established populations overwinter on light colored structures, in leaf litter, and underneath the bark of trees. Also, like stink bugs, adults tend to excrete an odor as a defense mechanism when disturbed. The defense chemical these insects secrete may stain the surface of the house, building or vehicle where aggregation occurs.
