Insect galls from Amazon rainforest areas in Rondônia (Brazil)

Abstract

Abstract This study aimed at survey insect galls of an Amazon rainforest area in Rondônia, Brazil. We found 152 gall morphotypes in 103 plant species. Fabaceae were the host with the greatest gall richness. Leaves were the most galled organ. Globose and glabrous galls were the most frequent. Cecidomyiidae were responsible for most of the galls. This is the first record of 110 galls morphotypes and 23 host plants species in this biome. Ten gallers are endemic in Brazil. Five genera of Cecidomyiidae were first recorded in Rondônia as well as Schismatodiplosis lantanae Rübsaamen, 1908.
