This study was carried-out with the purpose to know the correlation that exist in a corn field crop under the effect of the herbicide Quiron 400, during the rainy and dry season. It was done in San Roque, San Francisco,Veraguas. The specimens of Collembola were collected using pitfall traps, finding 8 families. A physiochemical analysis of the variables of the soil of the studied areas, was done by means of Principal Component test which determined that edaphic chemical factors had greater stronght on the Collembola families. Pearson,s correlation,s test were used to stablish correlation between Collembola,s families and edaphic physiochemical factors. Finally Bray-Curtis Cluster Analysis stablished similarities or relationships between the Collembola,s families and edaphic factors in the areas studied.
