13. Aspectos biotecnológicos da interação entre bactérias e cana-de-açúcar (Saccharum sp., L.) / Biotechnological aspects of bacteria-sugarcane (Saccharum sp., L.) interactions
Sugarcane is one of the most important Brazilian crops. Its importance is increasing due to the gradual substitution of fossil fuel for renewable and cleaner energy sources, such as ethanol Consequently, the biotechnological aspects that mediate sugarcane-bacterium interactions must be evaluated; studies from tropical countries are incipiente Bacterium-plant

14. Comparação da diversidade microbiana intestinal em larvas do campo e laboratório do bicudo da cana-de-açúcar, Sphenophorus levis (Coleoptera, Cucurlionidae)
The sugarcane weevil, Sphenophorus levis, is an important pest in sugarcane culture in São Paulo state, Brazil. To complete its life cycle, S. levis may depends on microorganisms that inhabit its intestinal tract and play an important key in the insect physiology and nutrition. In this study we report the characterization of the intestinal microbiota from p

15. Efeitos de inibidores de proteinases de soja em organismos não-alvo associados à cultura da cana-de-açúcar / Effects of soybean proteases inhibitors on non-target organisms associated to sugarcane
Genes of plants expressing insect proteinase inhibitors have been introduced into plants for pest control. Proteases inhibitors are present in plant tissues, mainly in seeds, and act in response to predators and pathogens. The Bowman-Birk type and Kunitz type of serine proteases inhibitors (PI) from soybean seeds are been used to increase resistance of sugar

16. Estudo da ação do inibidor de proteinase de Adenanthera pavonina sobre o desenvolvimento e atividade das proteinases intestinais de lagartas de Diatraea suchharalis (FABR., 1794) / Study of proteinase inhibitor action from Adenanthera pavonina on the development and midgut proteinase activities of the Diatraea sachharalis larvae (FABR., 1794)
Phytophatogous insects and other animals use digestive enzymes, such as amylases and proteinases to process the nutrients obtained from the plants necessary for their development. The sugarcane borer Diatraea saccharalis is the major pest of sugarcane in Brazil and other South American countries. Plants synthesize a variety of molecules, including proteinase

17. Economic injury levels of termites (Insetca: Isoptera) in sugarcane / Níveis de dano econômico para cupins (Insecta: Isoptera) em cana-de-açúcar
Cupins são considerados uma praga chave em cana-de- açúcar no Brasil e medidas preventivas são usualmente adotadas para o seu controle. Entretanto, não se sabe se cupins causam perdas à cultura em qualquer intensidade de infestação e tampouco se sabe quando a perda justiça economicamente o seu controle. O objetivo deste trabalho foi avaliar o efeito

18. SilÃcio na produtividade e no controle da cigarrinha-das-raÃzes Mahanarva fimbriolata Stal em cana-de-aÃÃcar / Silicon on the productivity and on the control of the spittlebug Mahanarva fimbriolata StÃl of sugarcane
The advent of automated sugarcane harvesting, and its replacement of traditional pre-crop burning, has created a favorable environment for the spittlebug Mahanarva fimbriolata StÃl. The spittlebug was previously considered a problem just in the sugarcane plantations of northeast Brazil, but it has now become one of the main problems for this culture in the

19. Biological and mannering studies of Migdolus fryanus (Westood, 1863) (Coleoptera: vesperidade) and its interaction with entomopathogenic nematodes and other agents of mortalities / Estudos biologicos e comportamentais de Migdolus fryanus (Westwood, 1863) (Coleoptera : vesperidae) e sua interação com nematoides entomopatogenicos, e outros agentes de mortalidade
During de present study biological and morphological data of Migdolus fiyanus (Westwood, 1863) (Coleoptera: V esperidae) were obtained. Males and females after mating were collected in sugar cane field and brought to the laboratory for morphological and biological investigations. Females were individualized in plastic containers ( 20 L). The dimensions were

20. Distribuição espacial e plano de amostragem para a cigarrinha-das-raízes, Mahanarva fimbriolata (Stal., 1854), em cana-de-açúcar. / Spatial pattern and sampling plan for sugarcane root froghopper , Mahanarva fimbriolata (Stål., 1854).
The objective of this research was to evaluate the spatial distribution of adults and nymphs of the sugarcane root froghopper, Mahanarva fimbriolata (Stal, 1854) (Hemiptera: Cercopidae), to evaluate the efficiency of the sampling system presently used to monitor the populations in commercial fields, and to estimate nymph populations by counting foam spots.

21. Análise da expressão gênica induzida por Diatraea saccharalis em cana-de-açúcar via macroarranjos de colônias bacterianas. / Analysis of expressed genes induced by Diatraea saccharalis in sugarcane using bacterial colonies arrays.
Large-scale sequencing and the application of expressed sequence tag (EST) technology has led to the identification of hundreds of thousands of genomic sequences from various organisms. Through projects like the Sugarcane Expressed Sequence Tag (SUCEST), DNA arrays technology could be applied in monitoring gene expression. The first step of this work was to
