“…The prevalence in our study of gall induction on leaves confirms the worldwide pattern observed since Felt (1940) and Mani (1964), and reinforced in previous inventories carried out in the Caatinga (Santos et al, 2011;Costa et al, 2014;Brito et al, 2018). As a general pattern, the globoid and fusiform morphotypes stood out as the most frequent.…”

“…Galls in the Caatinga biome began to be investigated only recently, with the first survey dating from 2011 (Santos et al 2011). Currently there are data for the states of Ceará, Pernambuco, Alagoas, and Bahia (Carvalho-Fernandes et al 2012, Costa et al 2014b, Nogueira et al 2016, Alcantara et al 2017, Brito et al 2018. However, the aspect that stands out about the occurrence of galls in this biome is the limited knowledge and the low number of inventories as compared to other Brazilian biomes such as the Atlantic Forest and Cerrado (Mendonça et al 2008, Stehmann et al 2009, Araújo et al 2019.…”

A survey and characterization of entomogenous galls and their associated fauna were carried out in six remnants of Caatinga in the Northern Depressão Sertaneja, in the states of Paraíba, Rio Grande do Norte and Ceará. We identified 41 gall morphotypes in 24 plant species, belonging to 12 botanical families. Fabaceae had 29.2% (n = 12) of the total number of gall morphotypes found. Leaves (61%) and stems (25%) were the most attacked organs. Most morphotypes are glabrous (75.6%), while only 24.4% exhibit trichomes. Most galls were induced by insects of the Cecidomyiidae family. The associated fauna comprised successors, cecidophages, tenants, and parasitoids. Sucessors were found in four morphotypes of galls and included spiders and four orders of insects: Hemiptera, Coleoptera, Lepidoptera, and Hymenoptera (Formicidae). The tenants were represented by Tanaostigmoides (Tanaostigmatidae). The parasitoids, found in 18 morphotypes (43.9%), were represented by six families of Hymenoptera. We recorded the occurrence of new types of galls in 12 species of host plants. These gall records are new references for the Northern Depressão Sertaneja in the studied states.

“…Um realizado por Carvalho-Fernandes et al (2012) e o outro por Brito et al (2018) ambas pesquisas estudaram os efeitos das atividades antrópicas em comunidades de insetos galhadores em áreas de Caatinga, contudo os resultados foram divergentes. Carvalho-Fernandes et al (2012) constataram uma riqueza maior de morfotipos de galhas nas áreas preservadas do que nas áreas intermediárias e antropizadas, enquanto Brito et al (2018) encontraram uma riqueza de galhas maior nas áreas intermediárias quando comparadas às áreas preservadas e antropizadas. Porém, ambos estudos, ressaltaram que os insetos galhadores podem ser úteis na avaliação do impacto humano sobre o ambiente.…”

O bioma Caatinga tem sofrido com grandes processos de degradação ambiental, que leva a fragmentação, perda do habitat e a uma crescente preocupação por uma restauração deste ambiente. Os insetos respondem de diferentes maneiras ao habitar gradientes sucessionais, sendo importantes na detecção de ambientes alterados. Por isso, o objetivo foi construir uma pesquisa bibliográfica acerca dos estudos desenvolvidos na Caatinga com foco na utilização dos insetos em avaliação de processos de restauração, regeneração ou sucessão de áreas degradadas neste bioma. O acesso à bibliografia foi feito eletronicamente, buscou-se por artigos científicos, no portal Google Acadêmico e de periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – CAPES, as buscas foram feitas entre 12/06/17 a 10/09/17 e em abril de 2020. As palavras chaves utilizadas foram em inglês e português e com relação ao tema proposto. Dos 112 artigos selecionados, apenas 18 estudos foram foco da revisão. A ordem de inseto mais estudada em áreas degradadas e/ou processo de regeneração é Isoptera, seguidos pela ordem Coleoptera e Hymenoptera. Todos os estudos apontaram grupos de insetos como bioindicadores, mas os resultados sobre assembleias, composição e riqueza de espécies foram divergentes para determinados grupos. Os trabalhos são pontuais em algumas ordens de insetos, mas aparentemente estão em legítima expansão e, assim, o bioma carece urgentemente de um maior aporte de pesquisas científicas, que permitirá um maior entendimento dos processos que catalisam a regeneração da vegetação nativa e a melhoria na capacidade de manejo de áreas degradadas. Palavras-chave: Degradação Ambiental. Insetos da Caatinga. Restauração Ambiental. Abstract The Caatinga biome has undergone major processes of environmental degradation, which leads to fragmentation, loss of habitat and a growing concern for the restoration of this environment. Insects respond in different ways to inhabit successional gradients, being important in detecting altered environments. Therefore, the objective was to build a bibliographic research about the studies developed in the Caatinga with a focus on the use of insects in the evaluation of restoration, regeneration or succession of degraded areas in this biome. Access to the bibliography was carried out electronically, scientific articles were searched on the google academic and of periodics of the Coordination for the Improvement of Higher Education Personnel - CAPES, the searches were made between 06/12/17 to 09/10/17 and in April 2020. The keywords used were in English and Portuguese and in relation to the proposed theme. Of the 112 selected articles, only 18 studies were the focus of the review. The most studied insect order in degraded areas and / or regeneration processes is Isoptera, followed by Coleoptera and Hymenoptera. All studies pointed out groups of insects as bioindicators, but the results on assemblages, composition and species richness were divergent for certain groups. The works are punctual in some orders of insects, but it seems that they are in legitimate expansion and, thus, the biome urgently needs a greater contribution of scientific research, which will allow a greater understanding of the processes that catalyze the regeneration of native vegetation and improve the management capacity of degraded areas. Keywords: Environmental Degradation. Caatinga Insects. Environmental Restoration.

“…The results corroborate the hypothesis that families with the highest number of plant species have proportionally the highest number of gall-forming species (Fernandes 1992;Mendonça 2007). Leguminosae is one of the main host families of galls in different Brazilian habitats (Araújo et al 2019, Santos-Silva and Araújo in press) such as caatinga (e.g., Carvalho-Fernandes et al 2012;Brito et al 2018), cerrado (Coelho et al 2009;Silva et al 2018;Vieira et al 2018), caatinga-cerrado transition areas (Costa et al 2014a, b;Nogueira et al 2016), and restinga (Maia et al 2008;Maia and Oliveira 2010). Myrtaceae also plays an important role in gall inventories conducted in Brazil (Maia 2013a(Maia ,b, 2014Maia and Souza 2013).…”

Inventories of insect galls in gallery forests in Northeastern Brazil have been quite infrequent, and the richness of gallinducing insects in that vegetation type has been little unknown. To contribute to our knowledge of galls, galling insects, and their host plants from gallery forest habitats in Northeastern Brazil, we documented and characterized the macroscopic aspects of the galls, identified the plant hosts and their endemism level and surveyed the associated fauna in an area of gallery forest in Caetité, Bahia State. We found 30 different gall morphotypes on 20 host plant species belonging to 17 genera and 13 families. The main host families of galls were Leguminosae and Myrtaceae with ten and four morphotypes, respectively. Most galls occurred on leaves and were globoid, green, glabrous, and grouped. Most of the gall-inducing insect species found belonged to Diptera (Cecidomyiidae) and Coleoptera, while the associated fauna was represented by Hemiptera, Hymenoptera, Collembola, and Thysanoptera. We recorded galls the first time on six plant species. These results reinforce the importance of gall inventories in gallery forest areas not yet examined to better understand gall richness, galling insects, and their host plants in that vegetation type.
