Embrapa Gado de Leite has the main Elephant Grass Germplasm Active Bank (BAGCE) in the country. However, the main species of grasshopper (Hemiptera: Cercopidae) and the genetic variability for resistance to these pest insects were not known. Therefore, the objective of this work was to study the population dynamics of spittlebugs and to evaluate the accessions of the elephant grass germplasm bank, regarding resistance to Mahanarva liturata. The population dynamics of cercopids in Coronel Pacheco

This project proposes the morphological and physico-chemical analysis of Brazil nut trees, in addition to the study of their diversity, intrapopulation spatial genetic structure, reproductive system, and patterns of seed and pollen dispersal in natural populations located in the Brazilian states of Mato Grosso and Acre. Furthermore, abiotic aspects such as weather variables and soil fertility and structure will be monitored, and there will be a survey on the constitution of the historical ethnob
