Se contaron directamente los ejemplares posados sobre las plantas y los machos adultos mediante detección auditiva. En Zapotitlán Salinas, Puebla se muestrearon los grillos en el día y en el Pedregal de San Ángel, Ciudad de México en la noche. La especie estuvo presente durante todo el año en ambos sitios y registró 5 estadios ninfales. La población de Zapotitlán fue multivoltina y la del Pedregal univoltina. La densidad promedio de grillos fue más alta en el Pedregal (652.0 ± 0.2 ind./ha) que en Zapotitlán (50.4 ± 0.2 ind./ha); la proporción sexual fue 1 macho:1.2 hembras en Zapotitlán, mientras que en el Pedregal fue de 6.1:1. En Zapotitlán se registró una densidad de machos significativamente menor (83.41 ± 5.3 ind./ha) en comparación con la del Pedregal (153.75 ± 9.1 ind./ha); en ambas localidades la densidad de machos estuvo correlacionada negativamente con los valores de precipitación acumulada mensual. Nuestros resultados resaltan la importancia de la estacionalidad en las variaciones poblacionales de los grillos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract We compared five population attributes of tree cricket Oecanthus fultoni Walker, 1962 (structure, density, abundance, sex ratio, and male density) in two localities of Central Mexico, with contrasting xerophytic scrub. The specimens were counted directly on plants and the adult males by aural detection. In Zapotitlán Salinas, Puebla the crickets were sampled in hours of the day, and in the Pedregal de San Ángel, Mexico City they were sampled in hours of the night. The species was present in both sites throughout the year and it recorded five nymphal instars; but the population of Zapotitlán was multivoltine and that of Pedregal was univoltine. The mean crickets density was higher in the Pedregal (652.0 ± 0.2 ind./ha) than in Zapotitlán 50.4 ± 0.2 ind./ha); sex ratio was 1:1.2 (males: females) in Zapotitlán; while in Pedregal it was 6.1:1. We recorded a significantly lower density of males in Zapotitlán (83.41 ± 5.3 ind./ha) than Pedregal (153.75 ± 9.1 ind./ha); in both localities males density showed negative and significant correlation with the monthly precipitation values. Our results support the importance of seasonality on the tree cricket population responses.]]></p></abstract>
