“…By the A2 scenario, the best estimate temperature rises 3.4°C with a likely range from 2.0 to 5.4°C; and in the B2 scenario, the best estimate temperature rises 2.4°C with a likely range from 1.4 to 3.8°C (Pachauri & Reisinger, 2007). Climate zoning studies for herbaceous cotton, using different suitable criteria, were developed in some states and producer regions in the country (Beltrão et al, 2003). However similar studies for all states were not found; thus, an innovative character can be attributed to the present work.…”

-The objective of this work was to evaluate the effect of the temperature increase forecasted by the Intergovernmental Panel on Climate Change (IPCC) on agricultural zoning of cotton production in Brazil. The Northeastern region showed the highest decrease in the low-risk area for cotton cultivation due to the projected temperature increase. This area in the Brazilian Northeast may decrease from 83 million ha in 2010 to approximately 71 million ha in 2040, which means 15% reduction in 30 years. Southeastern and Center-Western regions had small decrease in areas suitable for cotton production until 2040, while the Northern region showed no reduction in these areas. Temperature increase will not benefit cotton cultivation in Brazil because dimension of low-risk areas for economic cotton production may decrease.Index terms: Gossypium hirsutum, evapotranspiration, global warming. Impactos das mudanças climáticas no zoneamento agrícola de risco climático para o cultivo de algodão no BrasilResumo -O objetivo deste trabalho foi avaliar o efeito do aumento na temperatura, previsto pelo Painel Intergovernamental de Mudanças Climáticas (IPCC), sobre o risco climático para a produção de algodão no Brasil. O aumento previsto na temperatura fez com que a região Nordeste apresentasse a maior redução na área de baixo risco para cultivo de algodão, em comparação com as demais regiões do país. Essa área pode diminuir de 83 milhões de ha no ano de 2010 para aproximadamente 71 milhões de ha em 2040, o que significaria 15% de redução em 30 anos. As regiões Sudeste e Centro-Oeste apresentam pequena redução nas áreas aptas para o cultivo de algodão até 2040, enquanto a região Norte não teve redução nessas áreas. A elevação das temperaturas não é benéfica para a produção do algodão no Brasil porque a área de baixo risco para o cultivo econômico pode diminuir.Termos para indexação: Gossypium hirsutum, evapotranspiração, aquecimento global.

In the present work, we aimed to evaluate: 1) the influence of the Cry1Ac protein expressed by the genetically modified cotton variety (Bt) NuOpal, on the biological parameters of a non-target pest, Aphis gossypii, reared under laboratory conditions; 2) the influence of plant age on aphid development. Cotton cultivars were grown following technical advice. In the laboratory, the aphids were separated into plastic containers including a cotton sheet, which was changed daily with the help of a moist cotton cloth. Observations were carried out daily, and the duration of the immature and adult stages, and offspring number, were recorded. Our results show that regardless of the differences in the duration of each instar, cultivars Bt and non-Bt and the different ages of the plant to Bt, no differences were seen in the total duration of these phases. It was only during the reproductive period that differences were observed among genotypes for 120 days. Regarding the number of offspring and longevity total, there were differences between the different ages of the Bt treatment.
