Losses caused by the parasitism by ticks in cattle are estimated at 3.24 billion dollars annually in Brazil, largely due to procedural errors, such as the systematic and often inappropriate use of acaricides, resulting in selection and proliferation of populations of acaricide-resistant ticks. In addition, there is a growing demand for new alternatives in pest control, aiming at minimum use of chemicals, in order to preserve the environment and ensure residue-free food. In this context, biologic

The project consists of studying the parasitic communities of fish species such as catfish and scales fish in the Amazon River system. The main points of analysis are the description of these parasitic communities, description of new species and checking whether the size of the host fish has an influence on the abundance of these parasites, their diversity, seasonal variation and their dispersion in the fish. The parasitic communities of different species of fish will be compared, as well as

The tomato is one of the most cultivated vegetables in the world, and is the target of countless plant health problems. Embrapa Vegetables has historically produced research in plant health within this production chain under the scope of the Tomato Genetic Improvement Project. However, the increasing demand for studies aimed at perfecting pest diagnosis methods and generating essential information for management has signaled the need to create a specific plant health project. Thus, this project

Smallholder Capsicum pepper growers in Uganda are operating below the ideal levels of agricultural production due to a lack of improved varieties, low quality seed systems and the devastation caused by pests and diseases. The damages caused by diseases are aggravated by the cultivation of susceptible germplasm and the use of poor quality seeds. In order to increase production and competitiveness in the market, farmers need to have access to clean seeds of cultivars that are tolerant to diseas

One of the main post-harvest problems is the emergence of spoilage in oranges caused especially by fungi that depreciate the quality and decrease shelf life and may also compromise food safety. Various treatment technologies such as: modified atmosphere, irradiation, anti-microbial ice and high pressure, among others, have been studied in the quest to eliminate food pathogens. Thus, understanding mechanisms of microorganism control in foods have been the topic of intense research with the use of

In last the two decades, the melon agribusiness in Brazil has expanded nine times, reaching a production that is estimated at 500,000 tons per year and is concentrated in the Northeast. Since 2007, melons have become the main national fruit in volume of exports, and in 2008 Brazil was the second top world exporter. Nearly all melon cultivars planted in the Northeast are imported, and hence there is demand for more adapted ones, as the cultivars available were generally developed in soil and clim

The quick diagnosis of diseases in plants that have economic value is essential to guarantee food security and avoid larger losses as a consequence of disease spreading. Two major problems may hinder this goal: 1) the permanent monitoring of all the plants by people capable of detecting diseases is mostly unviable; 2) in many cases, the person who detects the symptoms doesn't have enough knowledge to identify their causes. Despite the existance of solutions that explore technology as a facilitat

Alzheimer's disease (AD) is a progressive degenerative disease of the central nervous system (CNS) that mainly affects people over 65 years of age, resulting in loss of memory and cognitive functions such as language, attention, orientation and reasoning. According to the World Health Organization (WHO), 24.3 million people worldwide suffered from AD and other types of dementia in 2007, with a doubling of this number every 20 years. That Organization also stresses that the impact of AD in develo

In the past years, Brazil has stood out for its leadership and high competitiveness in food production, a position reached especially due to the substantial efforts put into research, development and innovation, associated with free entrepreneurship, natural favorable conditions, abundant and efficient food production, and governmental efforts, notably those of the Ministry of Agriculture, Livestock and Food Supply (Mapa). However, if on one hand the quantitative issues regarding Brazil's food p

The Precision Agriculture Network counts with 20 Embrapa research Units and approximately 200 researchers: 15 experimental units distributed throughout the Northeast, the Mid-West, Southeast and South of the country; 11 perennial and annual cultures, and approximately 100 Research, Development and Innovation activities. The network was started at the end of 2009, and proposed to establish agricultural and stockbreeding concepts focused on space-time variability management for the sustainability
