          Abstract

          In the present work we aimed to register the occurrence of galls, inductors, inquilines, and parasitoids in plants of three natural vegetation areas in Delfinópolis, MG, Brazil. Results obtained showed 22 types of galls collected from leaf, vein leaf, petioles, stem, and inflorescence of nineteen species belonging to fifteen distinct families. Concerning gall morphology, the following were collected: globoid, conicle, discoidal, fusiform, shell-shape, indefinite, and one substituition of an ovary by an immature. As principal inducers were found insects of the families Cecidomyiidae (Diptera), Psyllidae, and Diaspididae (Sternorrhyncha/Hemiptera). As parasitoids the most common are of the Chalcidoidea superfamily (Hymenoptera) and, as occasional inquilines, Polyxenidae (Diplopoda) and Psocodea (Psocoptera). The results of this study contribute to existing of knowledge host-plant diversity and gall-associated insects in rocky fields, cerrado, and gallery forests.

          Neste trabalho registramos a ocorrência de galhas, galhadores, inquilinos e parasitóides em plantas de três áreas de vegetação natural em Delfinópolis, MG, Brasil. Como resultado foram obtidas galhas coletadas em folhas, nervuras de folhas, pecíolos, ramos e inflorescências de quinze famílias distintas. Quanto à morfologia, foram coletadas galhas globóides, cônicas, discóides e fusiformes, em forma de concha, uma sem formato definido e uma substituição do ovário pelo imaturo. Como principais indutores foram obtidos insetos das famílias Cecidomyiidae (Diptera), Psyllidae e Diaspididae (Sternorrhyncha/Hemiptera). Os parasitóides são da superfamília Chalcidoidea (Hymenoptera) e, como inquilinos ocasionais, Polyxenidae (Diplopoda) e Psocodea (Psocoptera). Os resultados deste trabalho contribuem para aumento do conhecimento sobre a diversidade de plantas hospedeiras e insetos galhadores associados à vegetação de campo rupestre, cerrado e mata de galeria.
