The water resource systems of the coastal region of the Piaui State, Brazil, are abundant
and of high productivity, favoring the use of the underground water for several ends such as, human consumption, irrigation and local tourism. Problems caused by the inadequate handling of the soil and the utilization of unsafe wells, are some of the factors that contribute, directly or indirectly, to the maintenance of the environmental quality of these resources. This study aimed to obtain current information on the physical and chemical characteristics to evaluate the underground water quality in six locations of the coastal region. Samples of 54 public and private wells were collected during the
2004 and 2005 dry season. The results were interpolated in geographical information system (GIS). It was concluded that the north and east costal region were the ones that presented the highest salinity indexes, presenting great restrictions to human consumption and irrigation.

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. |
