ABSTRACT

Trinta e seis diferentes tipos morfológicos de galhas foram obtidos em folhas, foliólulos, nervuras, pecíolos, ramos e inflorescências de vinte e cinco espécies de plantas na Reserva de Cerrado Pé-de-Gigante, Município de Santa Rita do Passa Quatro, SP, Brasil. As plantas hospedeiras pertencem às famílias: Anacardiaceae, Annonaceae, Asteraceae, Bignoniaceae, Caryocaraceae, Erythroxylaceae, Fabaceae, Malpighiaceae, Melastomataceae, Myrtaceae, Ochnaceae, Polygalaceae, Sapindaceae, Sapotaceae e Smilacaceae. Entre as famílias dos insetos galhadores foram observados Cecidomyiidae (Diptera), Pteromalidae (Hymenoptera) e Diaspididae (Sternorrhyncha-Hemiptera). Este é o primeiro relato da presença de galhas em plantas dos seguintes gêneros: Gochnatia (Asteraceae), Distictela (Bignoniaceae), Banisteriopsis (Malpighiaceae), Ouratea (Ochnaceae) e Bredemeyera (Polygalaceae). Os resultados deste trabalho contribuem para o aumento do conhecimento das relações entre plantas hospedeiras e galhadores e da morfologia das galhas da Reserva de Cerrado Pé-de-Gigante.

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.
