A balança comercial do agronegócio brasileiro de 1989 a 2005 AgEcon
Barros, Geraldo Sant'Ana de Camargo; Silva, Simone Fioritti.
This study aims to analyze the agribusiness contribution to Brazil’s trade balance. A new classification of the agribusiness trade balance was proposed and used to analyze the aspects of the exported products –agricultural products, products of animal origin, industrialized foods and imported inputs – represented by fertilizers. Imports and exports vector autoregression models were used to explain the behavior of these variables. An increase of 1% in the attractiveness – product of the exchange rate by the international prices – boosts immediately the exports of non processed agricultural products by 1.71%, stabilizing at 2% after some trimesters. The attractiveness explains 60 to 74% of the forecast error variances of these exportats. It is noted that an...

Assesing Bemisia tabaci (Genn.) biotype B resistance in soybean genotypes: Antixenosis and antibiosis Chilean J. Agric. Res.
Gonçalves Franco da Silva,José Paulo; Lopes Baldin,Edson Luiz; Santana de Souza,Efrain; Lourenção,André Luiz.
Since it was first reported in Brazil in the 1990s, the B biotype of silverleaf whitefly (Bemisia tabaci Genn., Hemiptera: Aleyrodidae) has been recognized as an important pest in soybeans (Glycine max L.), reducing the productivity of this legume species in some areas of the country. As an alternative to chemical control, the use of resistant genotypes represents an important tool for integrated pest management (IPM). This study evaluated the performance of 10 soybean genotypes prior to whitefly infestation, by testing attractiveness and preference for oviposition in the greenhouse and antibiosis in the laboratory. In a multiple-choice test, 'IAC-17' was the least attractive to insects. In a no-choice test, 'IAC-17' was the least attractive for egg...

Effect of food lures for monitoring of Anastrepha fraterculus (Diptera: Tephritidae) in Acca sellowiana (Myrtaceae). Repositório Alice
ROSA, J. M. da; ARIOLI, C. J.; PADILHA, A. C.; AGOSTINETTO, L.; BOTTON, M..
Abstract: The South American fruit fly, Anastrepha fraterculus (Diptera: Tephritidae) stands out for its polyphagous habit of damaging the production of several fruits in southern Brazil. This study aimed to evaluate the capture efficiency of A. fraterculus using grape juice at different periods of decomposition and aging as well as to test the capture efficiency of the enzymatic hydrolyzed protein Cera Trap® in feijoa crops. The work was conducted in a commercial feijoa orchard in São Joaquim, SC, Brazil during the 2014 growing season. Undiluted Cera Trap®, fresh grape juice and grape juice that had aged for 7 and 14 days were evaluated. All of the treatments with grape juice were used at the recommended concentration of 25 %. McPhail traps were used with...

Host Country Attractiveness for CDM Non-Sink Projects AgEcon
Jung, Martina.
In the present study, CDM host countries are classified according to their attractiveness for CDM non-sink projects. A cluster analysis is conducted based on three different factors determining host country attractiveness (mitigation potential, institutional CDM capacity and general investment climate) in order to elaborate a CDM host country classification. The results suggest that only a small proportion of potential host countries will attract most of the CDM investment. The CDM (non-sink) stars are China, India, Brazil, Argentina, Mexico, South Africa, Indonesia and Thailand. They are followed by attractive countries like Costa Rica, Trinidad and Tobago, Mongolia, Panama, and Chile. While most of the promising CDM host countries are located in Latin...
