Insect galls and associated fauna in two areas of Cerrado sensu stricto in the State of Bahia, Brazil.

This study inventoried and characterized the richness of galling insects based on gall morphotypes and their host plants in two Cerrado sensu stricto areas of Caetité municipality in Bahia State, Brazil, to aid the identification of galling insects and their host plants, as well as to contribute to the knowledge and conservation of local biodiversity. The survey was conducted in the Moita dos Porcos archaeological site and João Barroca Farm site, adopting the random walking methodology for sampling, during 12 months. We recorded 98 gall morphotypes on 42 plant species belonging to 36 genera and 22 families.

Occurrence and characterization of entomogenic galls in an area of Cerrado sensu stricto and Gallery forest of the state of Bahia, Brazil.

We surveyed insect galls in an area of Cerrado sensu stricto and Gallery forest in the municipality of Caetité (BA) to contribute to current knowledge of the local flora and its associated gall-inducing insects. Monthly collections were made between February/2015 and January/2016, totaling 12 field campaigns (involving two or three people and lasting four hours) that followed an established path through the countryside. A total of 63 gall morphotypes were identified on 47 host plant species belonging to 22 families; 17 morphotypes were found in the Gallery forest and 46 in Cerrado vegetation.

Diversity of insect galls associated with coastal shrub vegetation in Rio de Janeiro, Brazil.

Surveys in the coastal sandy plains (restingas) of Rio de Janeiro have shown a great richness of galls. We investigated the galling insects in two preserved restingas areas of Rio de Janeiro state: Parque Estadual da Costa do Sol and Reserva Particular do Patrimônio Natural Fazenda Caruara. The collections were done each two months, from June 2011 to May 2012.
