Predatory capacity and bioecological aspects of the Chrysoperla externa (Neuroptera: Chrysopidae) and its preys Sipha flava and Ropalosiphum padi (Hemiptera: Aphididae) in forage crops The pest aphids Sipha flava and Rhopalosiphum padi have caused significant injuries in elephantgrass and brachiaria swards, respectively. Thus, the objective of this project was to evaluate the bioecology of these pest insects and the predator Chrysoperla externa. The biological aspects of the pests were studied at 12, 16, 20, 24, 28 and 32ºC. Temperatures of 20ºC and 24ºC were more favorable for insect development, and this temperature range is the most appropriate for t ... Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007
Security issues in nanotechnology The use of nanotechnology has been putting nanoparticles and nanostructures in contact with live organisms in ways not yet fully understood. In agriculture, this interaction can occur on a large scale, such as in the applications of controlled release nanostructure-encapsulated pesticides whose toxicity inherent to the drug release system still requires continual verification. Cases like this have motivated the proposal of this project, whose objective was to evaluate the potential impact on liv Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011
Adaptação metodológica da avaliação dos riscos ambientais e sociais das agrinanotecnologias e subsídios para sua regulamentação. Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2012
Biothematic Evaluation and Quantitative Analysis of Sanitary and Phytosanitary Risks in the Scope of the National Agriculture and Stockbreeding Defense 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 Status: Completed Start date: Mon Nov 01 00:00:00 GMT-03:00 2010
Database of Quarentine Plagues Associated to Cultures Relevant to Brazilian Agri-Business and the Country's Phytosanitary Defense The goal of this project is to develop an integrated database system for the Department of Vegetal Sanity (DSV), the Secretary of Agriculture and Stockbreeding Defense of the Agriculture, Stockbreeding and Provision (Mapa), hoping to facilitate processes of risk analysis of plagues that attack vegetable products. The vegetable product imports which can be potential spreaders of plagues is normatized by the International Plant Protection Convention (IPPC), which is linked to the Committee of Sani Status: Completed Start date: Thu Apr 01 00:00:00 GMT-03:00 2010
