Combining an open source Geographical Information System like GRASS-GIS, Mapserver, and the computer languages Perl and PHP it was developed a flexible Decision Support System (DSS) based on fuzzy logic. The DSS researched use data gathered from a current research and demonstration project, concerning the distribution of the Olive fruit fly (Bactrocera oleae) according to several environmental ...

Insects form an extremely large group of animals and bear a consequently large variety of associated microbes. This microbiota includes very specific and obligate symbionts that provide essential functions to the host, and facultative partners that are not necessarily required for survival. The Tephritidae is a large family that includes many fruit pests such as the Mediterranean fruit fly (the...

The variation in gene frequency among populations or between generations within a population is a result of breeding structure and selection. But breeding structure should affect all loci and alleles in the same way. If there is significant heterogeneity between loci in their apparent inbreeding coefficients F=s(p) (2)/p(1-p), this heterogeneity may be taken as evidence for selection. We have g...
