Abstract
Thirty-one morphotypes of insect galls and two flower damages were found on 16 families, 22 genera and 24 plant species in Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ). Fabaceae and Myrtaceae were the plant families with the greatest richness of insect galls (4 and 6 morphotypes, respectively), and the greatest number of galled plants (four and three species, respectively). Galls were mostly found on leaves and stems (77% and 10%, respectively). The galling insects are represented by Diptera, Lepidoptera, and Hemiptera. The majority of the galls (81%) were induced by gall midges (Cecidomyiidae: Diptera).
Highlights
Insect galls are characterized by abnormal growth of plant tissues and involve cell hypertrophy and/or hyperplasia (Mani, 1964)
In the State of Rio de Janeiro, several insect galls inventories have been published in restinga areas, in the following localities: Arraial do Cabo (APA de Massambaba, Monteiro et al, 1994 and Ilha do Cabo Frio, Maia and Souza, 2013), Jurubatiba (Monteiro et al, 2004), Carapebus and Maricá (Maia, 2001), Grumari (Rio de Janeiro) (Oliveira and Maia, 2005), and Reserva Biológica Estadual da Praia do Sul (Ilha Grande, Angra dos Reis) (Maia and Oliveira, 2010)
A total of 31 insect gall morphotypes and two flower damages were found in 16 families, 22 genera and 24 plant species in this inventory (Figures 2-37)
Summary
Insect galls are characterized by abnormal growth of plant tissues and involve cell hypertrophy and/or hyperplasia (Mani, 1964). Some records of insect galls are known from Parque Municipal da Boca da Barra (Cabo Frio, Rodrigues and Silva, 2011), and Paraty (Fernandes and Maia, 2011). These inventories indicate a great richness of insect galls in this ecosystem.
