    Se examinó la diversidad de los mosquitos en los alrededores de de San Juan del Flumen, un pueblo del municipio de Sariñena (Los Monegros, Huesca, España). La diversidad, abundancia y distribución de las especies de mosquitos varían durante el año. La diversidad real (índice de Shannon) de las seis especies de mosquitos encontrados en la zona durante el estudio (Culiseta annulata, Culiseta longiareolata, Ochlerotatus caspius, Culex pipiens.

    We examined mosquito diversity in the surroundings of San Juan del Flumen, a village of Sariñena municipality (¿Los Monegros¿, Huesca, Spain). The diversity, the abundance, and the distribution of the mosquito species varied during the study period. The real diversity (Shannon index) of the six species encountered during the study period (Culiseta annulata, Culiseta longiareolata, Ochlerotatus caspius, Culex pipiens, Culex modestus and Anopheles atroparvus) represented 63.8% of the maximal diversity of a community of six species which would have the same abundance (H=1.14; ln(S)=1.79). The specific diversity was high at the beginning of spring (H=0.23) and low at the end of the study period. The differences between the larval densities of the four species encountered in spring were highest in March (ln(E)= -1.16). Site 3 (maize) registered the maximum number of species but diversity was higher at site 1 (maize, rice, alfalfa).
