Zika, a Mosquito-Transmitted Virus

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.

El Zika, un Virus Transmitido por Mosquitos

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.

Ejemplo Ilustrativo de los Costos y Rentabilidad de la Produccion de Aguacates en el Estado de la Florida

Los cultivos de árboles frutales son de gran importancia económica en la agricultura del estado de la Florida; en este segmento, la industria del aguacate ocupa el segundo reglón económico tras los cítricos. Aproximadamente el 80 por ciento de la cosecha se vende fuera del estado; por lo tanto, la industria aporta una cantidad considerable de “dólares nuevos” al estado, lo que resulta en un impacto económico total de cerca de $100 millones por año. Este artículo proporciona una estimación de los costos y rendimientos asociados a la producción de aguacate en el Condado de Miami-Dade y un breve análisis de la rentabilidad de la industria.

Improving the Precision of Blueberry Frost Protection Irrigation

In Florida, early-ripening southern highbush blueberry cultivars allow growers to take advantage of high prices in the early market before other states can compete with higher volumes of berries sold at lower prices. That advantage comes with a vulnerability, however, because frosts can reduce gains. Florida growers rely on strategies like cold protection irrigation to reduce their risk of loss due to cold damage. This 9-page article by Tatiana Borisova, Tori Bradley, Mercy Olmstead, and Jeffrey Williamson describes a UF/IFAS study comparing precision cold protection irrigation to uniform cold protection irrigation to estimate the potential savings in diesel costs and water withdrawal volumes associated with the two practices and help protect Florida’s valuable and vulnerable blueberry harvest.

The Social Organization of Honey Bees

A honey bee colony is a superorganism, which means that together its members function like a single animal. Bees within a colony work together like the cells in a human body. They warm the colony in the winter by vibrating their wings to generate heat and cool it in the summer by ferrying in droplets of water and fanning air over them. Worker bees fan air into and out of the colony entrance in distinct inhalations and exhalations. Colonies reproduce by swarming to create new daughter colonies that in turn thermoregulate, breathe, and reproduce just as a single autonomous animal does. In three pages this fact sheet explains the intricate caste system and age-based division of labor that allows colonies of humankind’s best-loved pollinators to function and thrive. Written by Ashley N. Mortensen, Bryan Smith, and James D. Ellis and published by the Entomology and Nematology Department.
