Great part of the original vegetation of the State of Amazonas are preserved, however, at south and southeast regions, where the majority of deforested areas are located, deforestation has increased. Land settlement projects could be related to deforestation as an intermediate agent. In order to understand this matter, land use and coverage were temporally analyzed at Santo Antônio do Matupi Settlement Project (PA Matupi, Manicoré ? AM), between 2000 and 2008, using digital maps from PRODES/INPE. Factors related to the settlement colonization were also analyzed through information from Instituto Nacional de Colonização e Reforma Agrária de Humaitá (National Colonization and Agrarian Reform Institute at Humaitá) in a geographic information system. The process of colonization started in 1995 and most lots at PA Matupi were occupied and its settlers possessed land tittles, although, there are many evaded lots and some of them were re-colonized. The conversion of forested areas to agricultural usage areas has increased from 2000 to 2008. The evasion process and settlers switching may indicate the relation among social factors linked to land occupation and also to the shift from crop farming to animal raise activity on the dynamics of the settlement landscape. So, researches focused on those relations are necessary to understand the role of settlements on deforestation processes in Amazon. |

Several studies have shown intraspecific geographical variation in the composition of sex pheromones. Pheromone lures from North America and Europe were not effective against the fall armyworm Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) in Brazil, so we examined the composition of the sex pheromone produced by females from Brazilian populations. Virgin female gland extracts contained (Z)-7-dodecenyl acetate (Z7-12:Ac), (E)-7-dodecenyl acetate (E7-12:Ac), dodecyl acetate, (Z)-9-dodecenyl acetate, (Z)-9-tetradecenyl acetate (Z9-14:Ac), (Z)-10-tetradecenyl acetate, tetradecyl acetate/(Z)-11-tetradecenyl acetate (Z11-16:Ac), and (Z)-11-hexadecenyl acetate. The relative proportions of each acetate were 0.8:1.2:0.6:traces:82.8:0.3:1.5:12.9, respectively. This is the first time that E7-12:Ac has been reported from the pheromone gland of S. frugiperda. Only three compounds, Z9-14:Ac, Z7-12:Ac, and E7-12:Ac, elicited antennal responses, and there were no differences in catch between traps baited with either Z7-12:Ac + Z9-14:Ac or Z7-12:Ac + Z9-14:Ac + Z11-16:Ac blends. However, the Z7-12:Ac + Z9-14:Ac + E7-12:Ac blend was significantly better than Z7-12:Ac + Z9-14:Ac, indicating that E7-12:Ac is an active component in the sex pheromone of the Brazilian populations of S. frugiperda. |
