Gonzáles, Wilfredo L.; Gianoli, Ernesto (2003)The preference-performance hypothesis predicts that insect preference should correspond to host suitability for offspring development. We studied the pattern of within-plant preference in the aphid Sipha flava and its ...

Suárez, Lorena H.; Gonzáles, Wilfredo L.; Gianoli, Ernesto (2009)Pollination is a requisite for sexual reproduction in plants and its success may determine the reproductive output of individuals. Pollinator preference for some floral designs or displays that are lacking or poorly developed ...

Gonzáles, Wilfredo L.; Fuentes-Contreras, Eduardo; Niemeyer, Hermann M. (2002)Competition between phytophagous insects could be mediated by differential impact of natural enemies or by induced changes in host plant quality. The interaction between the aphids Sipha flava and Rhopalosiphum maidis on ...

Gonzáles, Wilfredo L.; Suárez, Lorena H.; Medel Contreras, Rodrigo (2007)Most studies on the fitness advantage of outbreeding in host-parasite systems have been assessed from the host rather than the parasite perspective. Here, we performed experimental pollination treatments to evaluate the ...

Gonzáles, Wilfredo L.; Suárez, Lorena H.; Guiñez, Ricardo; Medel Contreras, Rodrigo (2007)The ability of a genotype to respond to changes in the environment through modifications in the phenotype is adaptive when the plastic genotypes attain a higher fitness than non-plastic genotypes. In this study we examine ...
