Resumo
The present study aimed to increase knowledge about the diversity and factors that determine the distribution of
galling insects in the Parque Nacional do Itatiaia (PNI), Southeast, Brazil. For this, collections were performed in April, August
and November 2015 and March 2016. Seventy gall morphotypes were found in 12 families, 32 genera and 61 species of host
plants. The richness of galls did not vary with altitude, but increased with the richness of plants. The families and genera of
plants with greater species richness harbored a greater number of galling insects. The number of gall morphotypes was higher
in the autumn than in the other seasons. The spatial distribution of galling insects was better explained by factors such as
floristic richness and species composition than by ecological effects, represented here by altitude. Regarding seasonality, the
results indicate that the way resources are temporarily distributed to galling insects depends on factors such as the active
growth of host plants, making some periods of the year more conducive to the development of galls.
