Resumen: "Coccinellids are important predators and provide important ecosystem services. Thecoccinellid fauna, drivers of assemblage composition, and species richness in the tropicsare poorly known. We studied changes in species composition of coccinellids indomestic gardens along a rural-urbangradient in southeastern Mexico and identifiedthe local and landscape variables that determine abundance and species richness.We surveyed coccinellids through monthly visual surveys, yellow sticky and pantraps in nine domestic gardens, and measured local variables (flower and prey abundance,plant diversity, garden size, temperature, and relative humidity), and gatheredinformation on landscape heterogeneity in buffers around gardens (0.05 km, 1 km,and 3 km radius). We collected 40 coccinellid morphospecies, including two exoticspecies: Chilocorus nigrita and Delphastus catalinae. Coccinellid species compositiondiffered along the gradient. Assemblages did not exhibit a nested pattern"
