Abstract
Conservation Units (CUs) tend to have a high richness of herbivorous insects, including gall-inducing insects. Despite this, gall surveys carried out in these environments are punctual and some units have never had their galls investigated, such as the Chapada Diamantina National Park, Bahia (Chapada Diamantina Parna). Aiming to reduce this gap and contribute to future studies in CUs, this study aimed to survey the galls of the Chapada Diamantina Parna, Lençóis, as well as to investigate trends in research on galls in CUs in Brazil. For that, collections were carried out on monthly trips for one year. Published gall surveys were compiled. A total of 107 morphotypes induced in 88 host species were recorded. Most galls are formed in leaves, globoid in shape, green in color, and induced by Cecidomyiidae. This park has a relatively high richness of galls compared to other CUs, demonstrating its importance in the conservation of gall-inducing insects. The results also revealed that the number of surveys has been increasing over the years and that the Southeast concentrates the largest number of studies, a region that also gathers the largest number of specialists, demonstrating a geographic bias in the data.

Abstract
An inventory of insect galls of Serra da Bodoquena (MS, Midwestern Brazil) was carried out in an area of semideciduous seasonal forest situated in the Califórnia Farm. Three field works were done in August/2011, December/2011 and April/2012, when the local vegetation was examined during 40 hours per expedition. Fifty-eight gall morphotypes were found on 40 host plants, 38 of them native. The host plants are distributed in 18 families. The native plants include eight endemic species in Brazil, which together totaled 14 gall morphotypes. Zanthoxylum L. sp. (Rutaceae), an endemic genus in Brazil, hosts one gall morphotype. The non endemic native plants totaled 26 gall morphotypes. Ten new host plants are recorded for the first time in Brazil. The medium number of gall morphotypes per plant species was 1.45. Salicaceae, Bignoniaceae, and Asteraceae presented the highest number of galled species and the greatest gall richness. Leaves were the most frequent galled plant organ and there was a predominance of globoid galls. Diptera (Cecidomyiidae) were the most frequent gallers, but Hemipteran and Thysanopteran galls were also found. The associated fauna was composed of inquilines (Diptera: Muscomorpha and Cecidomyiidae - Trotteria sp., and Thysanoptera), successors (Psocoptera), and parasitoids (Hymenoptera).

Abstract
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. Leguminosae, Malpighiaceae and Myrtaceae demonstrated the greatest richness of galls, and the Copaifera langsdorffii was the super-host species, with 16 gall morphotypes. Most galls occur on leaves, and may be globoid, glabrous, grouped, and are usually unilocular, and brown. The galling insects identified belonged to Coleoptera, Diptera, Lepidoptera, and Thysanoptera. Eight plant host species and eight gall morphotypes were recorded for the first time in Cerrado areas in Brazil. The areas surveyed demonstrated high richness of gall morphotypes and host plants, evidencing the importance of studying and preserving different areas of the same biome.

Abstract
Several records of associated fauna, including parasitoids, inquilines, predators, and successors, have been reported by insect gall inventories in Brazilian restingas. Although most guilds are well established, inquilines have frequently been misinterpreted. In this paper, the inquilinous fauna of insect galls is revised based on five criteria: food habit; coexistence with the inducer; modification of gall tissues or production of new tissues; phylogenetic relationship with the inducer; and mobility. Gall inventories dated from 1988 to 2019 were examined, totaling 16 publications, eight of them with inquiline records. This guild was reported in 53 gall morphotypes in 44 plant species and four morphospecies distributed among 36 genera of 24 host families for a total of 65 records. Most inquilines were repositioned into the cecidophage guild and others into the kleptoparasite guild, resulting in a large reduction in the frequency of inquilines (from 65 to five records), and in first reports of cecidophages and kleptoparasites, with 46 and 13 records, respectively. Cecidophage was the most diverse guild with insects of five orders (Diptera, Coleoptera, Lepidoptera, Hemiptera, and Thysanoptera) while kleptoparasites were represented only by two orders (Diptera and Hymenoptera) and inquiline solely by Hymenoptera. Other results indicate that Leptothorax sp. (Formicidae) could be a successor and not an inquiline.

Abstract
Abstract: Most Neotropical species of Cecidomyiidae (Diptera) have been described from Brazil, but a list of species with occurrence in the country has never been published. Little is known about their distribution and richness in the Brazilian phytogeographic domains. Additionally, a list of host plant species has never been gathered. The present study aims to fill these knowledge gaps and provides an overview of this family in Brazil. For this, data were obtained mainly from the literature, but also from the Cecidomyiidae collection of Museu Nacional and two herbaria (RB and R). Based on the site "Flora do Brasil 2020", botanical names were updated and plant species origin and distribution were verified. A total of 265 gall midge species have been recorded in Brazil, most from the Atlantic Forest (183), followed by Cerrado (60), and Amazon Forest (29). The other phytogeographic domains shelter from five to ten species. Phytophagous gall midges occur on 128 plant species of 52 families, almost all native, being 43 endemic to Brazil (21 endemic to Atlantic Forest, five to Cerrado, and one to Amazon). Although, the taxonomical knowledge is focused on the Atlantic Forest, each domain has its own fauna composition and these informations can be useful for environmental conservational purposes. About 58% of the Brazilian fauna are known only from the type-locality. In order to fill these gaps, it is necessary and important to collect in uninvestigated areas.

Abstract
Abstract: Caatinga is a seasonally dry tropical forest, one of the richest in plant species. Unfortunately, many groups of herbivorous insects associated with these plants are poorly known. This study aimed to investigate the diversity of gall-inducing insects (GII) and host plants (HP) in the Caatinga. For this, we compiled the information available in the literature of inventories on GII and their HP communities, and the described gall midge species. We found 100 species, 72 genera, and 32 families of HP hosting a total of 156 morphospecies of GII and 12 species of described cecidomyiids. Plant species with only one GII species represented 74% of hosts, but in super HP (i.e., HP with a high number of GII), despite the small number of HP species, there were many GII species. Fabaceae was also the most specious family, with 30% of HP species and 40% of GII. Furthermore, our results showed a low number of species of HP and GII for the Brazilian Caatinga, that we discussed this pattern with the following arguments, first, it is likely that the number of galling insect inventories for the Caatinga is under-sampled, second the Caatinga has a relatively smaller number of plant species when compared to other biomes, and finally, we argue that the Caatinga is a seasonally dry tropical forest where the deciduousness represents a relevant factor in the colonization and performance rates of GII.

Abstract
In general, insect herbivore diversity is positively correlated to plant diversity since plant assemblages structure different microhabitats and provide food resources for such insects. Although poorly studied, insect herbivores in tropical dry forests are positively affected by tree species richness and the structural architecture of vegetation. In this study, we analyzed whether true weevil and woody plants present similar patterns of diversity across different landscape units in a Neotropical tropical dry forests located in Brazil, and if there is a correlation among their assemblages. We used Hill numbers according to species richness and the inverse of Simpson to compare the taxonomic diversity of true weevils and plants in nine landscape units located at the São Francisco river basin in the states of Sergipe and Alagoas, north-eastern Brazil. All trees and shrubs with diameter at breast height (1.3 m) ≥ 5 cm were sampled, and true weevils were collected using a modified Malaise trap. We used co-correspondence analysis to test if plants and true weevil species tend to co-occur. A total of 538 true weevils from 60 species was collected, and a total of 1419 plants belonging to 49 species was recorded. There is no general pattern of co-occurrence and diversity among true weevils and plants, indicating that the plant community is not structuring true weevil assemblage in the Caatinga. However, there was positive relationship between Sibinia sp4 and Fabaceae-Mimosoideae. These results suggest true weevil-plant relationships in the Caatinga differ from that of more mesic ecosystems. Therefore, we observed that the mechanisms that regulate herbivore-plant diversity relationships do not always follow a positive relationship, as observed in previous studies.
