Managing Insecticide and Miticide Resistance in Florida Landscapes

Blissus insularis on St. Augustinegrass6 - Buss

Resistance to insecticide or miticide is a worry for landscape managers. Around the world, chinch bugs, leafminers, and other insect and mite pests have become resistant to dozens of insecticides, but with diligent insecticide resistance management, we can still maintain long-term effective chemical control. With few new modes of action coming onto the market, landscape managers need to be good stewards of existing products. Ultimately, resistance management means reducing exposure of pests to any one pesticide. Fortunately, there are many ways to prevent resistance and still control pests of ornamental plants and lawns, and this 6-page fact sheet written by Nicole Benda and Adam Dale and published by the UF/IFAS Entomology and Nematology Department explains how.

Biology and Management of the Bermudagrass Mite, Eriophyes cynodoniensis

Characteristic tufting damage wrought by Bermudagrass mites to ‘Celebration’ bermudagrass shoots in a heavily infested golf course fairway.

The bermudagrass mite, Eriophyes cynodoniensis (Sayed) (Arthropoda: Arachnida: Eriophyidae), also known as the couch grass mite, can be a serious pest of bermudagrass in multiple high-maintenance turf systems such as sod production, athletic fields, and golf courses. Mites cause leaf and bud galls, which can lead to severe aesthetic damage and plant decline or death in high-maintenance areas with low tolerance for plant damage. In this 7-page fact sheet written by Pablo Agustin Boeri, Nicole D. Benda, J. Bryan Unruh, and Adam Dale and published by the UF/IFAs Entomology and Nematology Department, review the biology, identification, and management of the bermudagrass mite, and get specific management recommendations based on evidence from UF/IFAS research.

Assessment-based Pest Management of German Cockroaches

Assessment-based pest management emphasizes the importance of evaluating the intensity of a pest problem before treating the problem. This 10-page fact sheet written by F.M. Oi, E. Weeks, J. Jonovich, and D. Miller and published by the UF/IFAS Entomology and Nematology Department explains the strategy and includes a decision flow chart to provide an easy-to-follow overview on how a German cockroach problem can be assessed and successfully managed with specific guidance for each of four levels described in the fact sheet. The levels described constitute an escalation protocol that may approximate the tiers in a LEED (Leadership in Energy and Environmental Design) pest-management plan and may meet the requirements of some “green” pest-management certification programs, depending on level.

Ants are one of a beekeeper’s most common pests, both in the apiary and in the honey house. Florida and the southeastern United States have a large and diverse ant fauna, with both native and exotic species. The vast majority of ant species have no impact on our bees or us. This 8-page fact sheet written by William H. Kern and published by the UF/IFAS Department of Entomology and Nematology describes the few pest species can cause serious problems and suggests ways to control the ants for healthier hives.

Whiteflies are a common pest of many ornamental plants throughout Florida and the world. There are more than 1,500 species worldwide and over 75 reported in Florida. Although infestation does not always require treatment, it is important to be able to identify and monitor for these pests for effective integrated pest management. This 8-page fact sheet written by Eileen A. Buss, Catharine Mannion, Lance Osborne, and Adam Dale and published by the Entomology and Nematology Department describes whitefly species, their identification and biology, the damage they cause, and best management practices to control them and still maintain healthy populations of natural enemies and other beneficial insects.

Zika Vector Control for the Urban Pest Management Industry

Figure 2. Aedes aegypti (left) and Aedes albopictus (right). Credits: Florida Medical Entomology Laboratory.
Zika is a mosquito-transmitted virus that has recently spread to the Americas. Zika virus (ZIKV) was discovered in 1946 in Africa where it was isolated from a Rhesus monkey in the Zika forest of Uganda. In 2007, a disease outbreak occurred on the Yap islands in Micronesia, and in 2013, an outbreak occurred in French Polynesia. In 2015, a large outbreak occurred in Brazil, and ZIKV has since spread through the Americas. As of April 18, 2016, 15 counties in the state of Florida had reported travel-associated Zika cases. This seven-page fact sheet provides an overview of ZIKV, including its incidence and distribution, transmission and symptoms, and the connection between zika virus and infant microcephaly. This article also explains the biology and identification of the mosquito that vectors the virus with a focus on how to manage the vector using inspection, larviciding, adulticiding, monitoring, and personal protective equipment. Written by Casey Parker, Roxanne Connelly, Dale Dubberly, Roberto Pereira, and Philip Koehler and published by the Entomology and Nematology Department.

Zika, a Mosquito-Transmitted Virus

aegypti_albo2 blrrb
Zika is a mosquito-transmitted virus that has spread broadly in tropical regions and caused epidemics, especially in the past 8 to 9 years. In its native range in West Africa and Uganda, the Zika virus stays in the forest for the most part, and human infections are considered incidental and medically inconsequential. In 2015, however, Zika became a larger concern when a strain of the virus traced to outbreaks in French Polynesia emerged in northeastern Brazil. This strain provoked alarm because of increased incidence of microcephaly in babies born to Zika-infected mothers. Local transmission, mainly by the yellow fever mosquito Aedes aegypti, has now been documented in most tropical countries of the Americas but has not yet been detected in the continental United States. This 7-page fact sheet written by L. P. Lounibos, B. W. Alto, N. D. Burkett-Cadena, C. C. Lord, C. T. Smartt, C. R. Connelly, and J. R. Rey and published by the Department of Entomology and Nematology describes the Zika microbe, its mosquito hosts, and the disease it causes. A history of the virus and its migration are included, along with some details about the virus in the state of Florida and preventative measures people can take to avoid infection. The best way to avoid contracting Zika (and other mosquito-borne diseases) is not to get bitten in the first place. Take precautions to avoid mosquito bites.

Many types of traps can be used to monitor or control insect pests. Traps to capture insects vary greatly, depending on the target, location, and purpose. Traps may be inexpensive and disposable, or more complex. This 12-page fact sheet describes several traps for common pests in the home, garden, and landscape that can be made using common household materials or that are readily available in stores.

El Zika, un Virus Transmitido por Mosquitos

aegypti_albo2 blrrb
Zika es un virus transmitido por mosquitos que se ha esparcido recientemente en regiones tropicales y ha causado epidemias, especialmente durante los últimos 8 o 9 años. En su ámbito nativo en África Occidental y Uganda, el virus se mantiene en los bosques, circulando entre mosquitos que viven en huecos de árboles y primates arbóreos; las infecciones de humanos se consideran incidentales y de poca importancia médica. Una cepa del virus que se implicó en brotes en Polinesia Francesa emergió en el Norte de Brasil en el 2015 y causó gran consternación debido a la alta incidencia de microcefalia en bebes nacidos de madres que fueron infectadas con el virus durante la gestación. Transmisión local, principalmente por el mosquito de la fiebre amarilla Aedes aegypti, ha sido documentada en la mayoría de los países tropicales de las Américas, pero aún no se ha detectado en Los Estados Unidos Continentales. Los síntomas de la infección incluyen, salpullido, dolor de cabeza, fiebre, dolor muscular y en las coyunturas, conjuntivitis, y malestar general.
