Abstract: Insect galls host a rich and diverse fauna of secondary dwellers, which compose the associated fauna. In Brazil, many inventories of insect galls in Cerrado areas have recorded secondary dwellers. These records were scattered in several papers. This study gathered literature data to provide an overview of the arthropod fauna associated with insect galls in the Brazilian Cerrado. We searched for scientific publications in online academic databases and retrieved 16 papers with data on the secondary dwellers. We limited our search to the period from 1988 to 2020. We updated the name of plant species and verified endemism and geographic distribution in Flora do Brasil 2020. We provided plant species uses based on the Tropical Useful Plants 2014. We found 163 gall morphotypes with secondary dwellers (16.8% of the total of gall morphotypes of the Brazilian Cerrado) on 94 plant species in 37 families. Asteraceae, Fabaceae, Myrtaceae, and Malpighiaceae exhibited the greatest number of records. These are the richest families in insect galls in the Brazilian Cerrado. Most arthropod fauna were recorded in galls of Cecidomyiidae (Diptera). Most records were in leaf galls, the predominant galled organ. Parasitoids were more frequent than successors, inquilines, and predators. Eulophidae and Eurytomidae were the most frequent parasitoid families. Inquilines were represented by Coleoptera, Diplopoda, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Psocoptera, and Thysanoptera; successors by Acari, Araneae, Cecidomyiidae (Diptera), Coleoptera, Collembola, and Formicidae (Hymenoptera), whereas predators by Pseudoscorpiones and Diptera. Most records were presented in suprageneric categories, showing that the taxonomic knowledge is very deficient. 29 plant species are endemic to Brazil and totaled 45 gall morphotypes with secondary dwellers; 46 plant species are useful and host secondary dwellers in 62 gall morphotypes. These data add ecological and economic importance to these arthropods.

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.

Six localities of São Tomé das Letras (MG, Brazil) were investigated from September, 2011 to June, 2012. The local vegetation was examined in search of insect galls. A total of 152 morphotypes of insect galls were found on 94 plant species (74 genera and 37 families). Fabaceae, Melastomataceae, Myrtaceae, and Asteraceae were the plant families with the greatest richness of galls, with 20, 18, 17, and 12 gall morphotypes, respectively. The super host genera were Copaifera L. (Fabaceae), Myrcia DC. ex. Guill. (Myrtaceae), and Miconia Ruiz & Pav. (Melastomataceae), with 10, 10 and 09 gall morphotypes, respectively. The super host species was Copaifera cf.langsdorfii Desf. (Fabaceae), with 10 gall morphotypes. Galls were found on leaves, stems, buds, and aerial roots. Leaves were the most galled plant organ, followed by stems, and buds. The inducers belong to Diptera, Lepidoptera, Hemiptera, Thysanoptera, Coleoptera, and Hymenoptera, being Cecidomyiidae (Diptera) the most frequent and diversified gallers. The associated fauna included parasitoids (Hymenoptera), inquilines (Lepidoptera and Thysanoptera), successors (Formicidae, Hymenoptera), and predators (pseudoscorpion), obtained from 18, 02, 02, and 01 gall morphotype, respectively. Ten galling species are recorded for the first time in São Tomé das Letras (MG). The present study indicates São Tomé das Letras (MG) as an area of great richness of insect galls.

Seventy six morphotypes of insect galls were found on 38 plant species and one subspecies distributed among 27 genera and 22 families in Platô Bacaba (Porto de Trombetas, Pará, Brazil). The majority of these galls (about 80%) occurred on leaves and 20% on stems. Burseraceae was the plant family with the greatest number of gall morphotypes (N = 23), followed by Fabaceae (N = 11) and Melastomataceae (N = 6). Protium Burm. f. (N = 17), Inga Miller (N = 8), and Tetragastris Gaertn (N = 6) were the plant genera, and Protium sagotianum Marchand (N = 7), Tetragastris panamensis (N = 6), and Miconia stenostachya DC. (N = 5) were the plant species that supported the highest diversity of galls. The galling inducers belong to Diptera (Cecidomyiidae) and Lepidoptera orders. Galls of Coleoptera, Hymenoptera, Hemiptera and Thysanoptera were not found. This study adds evidences that Diptera (Cecidomyiidae) are the most frequent galling insects in different zoogeographical regions.

Abstract. Insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). Galls are changes in the pattern of growth and development of plant tissues or organs in response to the action of an inducing organism, usually an insect. The goal of the present study was to inventory the insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). The collections were carried out along all the trails, totaling 16 hours of sampling. Forty-three morphotypes of insect galls were found in 24 plant species (18 genera and 15 families). Sapindaceae and Euphorbiaceae were the most richness host plant families. Six new records of host plant species are presented: Senefeldera verticillata (Vell.) Croizat. (Euphorbiaceae), Inga acuminata (Fabaceae), Ocotea elegans (Lauraceae), Ouratea stipulata (Ochnaceae), Psychotria nuda (Rubiaceae) and Cestrum intermedium (Solanaceae). Most of the galls occurred on leaves (n = 21) and stems (n = 18), followed by buds (n = 2), two gall morphotypes occurred simultaneously on leaves and stems. One-chambered galls were more frequent (n = 31), as well as glabrous galls (n = 33). The gallers belong to three insect orders: Diptera (Cecidomyiidae), Hemiptera, and Lepidoptera. The associated fauna comprised parasitoids (Hymenoptera), inquilines (Hemiptera and Coleoptera) and successors (Isoptera and Acari).

Abstract: The Midwest region of Brazil possesses large areas dominated by the Cerrado that is poorly known concerning insect gall and their interactions. In this study, we inventory the gall morphology, host plants, and the gall makers from Parque Nacional da Chapada dos Guimarães, Mato Grosso State, in areas of natural vegetation from Cerrado, for the first time. Samplings occurred in two expeditions, July 2012 and January 2013. We characterized 295 morphotypes of insect galls in 140 host plant species, with 89 gall makers; the richest family in host plants was Fabaceae (16.7%), and the species was Protium heptaphyllum (Aubl.) Marchand (Burseraceae, 3.7%). Parque Nacional da Chapada dos Guimarães is the richest Brazilian cerrado area in gall morphotypes (295) and the second in average morphotypes/host plant species (2.1). Additionally, six genera and 38 species are new records as host plants; two of them, Bernardia similis Pax and K.Hoffm and Ormosia macrophylla Benth., are new occurrences for Mato Grosso State, and other two, Vochysia petraea Warm. and Talisia subalbens (Mart.) Radlk. are listed in the Red List of Threatened Species IUCN. This inventory data represents a testimony of insect-plant interactions in a Brazilian Cerrado area that was consumed by an unprecedented fire in the dry season of 2020.

In this study we recorded the occurrence of insect galls, inductors and parasitoids in plants of several physiognomies of Brazilian Cerrado in the Serra dos Pireneus, Goiás State, Brazil. We found 62 morphotypes of gall on 28 botanical families, comprising 44 genera and 51 species. The plant families that showed the greatest richness of galls were Fabaceae, with eight morphotypes, and Styracaceae with six. Styrax pohlii (Styracaceae) was the host plant species with the greatest gall richness, featuring five morphotypes. Most of galls occurred on the leaves (82.6%), 45.1% in vegetation of typical savanna and 35.4% in rocky savanna. Dipteran, Hemipteran and Lepidopteran galls were found, being 50.9% of them induced by Cecidomyiidae (Diptera). Several parasitoids were obtained, Eulophidae (Hymenoptera: Chalcidoidea) was the most representative group (occurring in approximately 40% of the galls). Nine species of plants were recorded for the first time in the Neotropical as host of gallers.

Abstract: We investigated insect galls in Rupestrian field and Cerrado vegetation in the municipality of Caetité (BA), Brazil, between August/2015 and June/2016. This is the first study of gall diversity in Rupestrian field vegetation in that state. We encountered 48 different morphotypes of galls, distributed among 17 different plant species belonging to 13 genera and 21 host plant families. The greatest gall richness was observed in Cerrado (n=39) as compared to Rupestrian field (n=9) vegetation. The principal botanical families observed with galls were Leguminosae, Malpighiaceae, and Myrtaceae, with 10, 8 and 4 morphotypes, respectively. The genera showing the greatest gall diversity were Copaifera L. (n=6) (Leguminosae-Detarioideae), Croton L. (n=2) (Euphorbiaceae), Mimosa L. (n=2) (Leguminosae-Caesalpinioideae), Byrsonima Rich. ex Kunth (n=2) (Malpighiaceae), and Eugenia L. (n=2) (Myrtaceae). The super-host species was Copaifera sabulicola J.A.S. Costa & L.P. Queiroz (n= 5). Most galls occurred on leaves, being globoid, glabrous, isolated, and unilocular. Most gall-inducing insect species belong to the Cecidomyiidae family, while the associated fauna was represented by Hymenoptera and Lepidoptera. We recorded here for the first time galls on Ocotea velutina (Mart. ex Ness) Rohwer (Lauraceae) and Miconia alborufescens Naudin (Melastomataceae). The results indicate the need for more studies to understand the dynamics of the insect-induced galls in Rupestrian field.

An inventory of the insect gall from Brazilian savanna (Cerrado) was elaborated based on samples of the collection of the Museu Nacional, Universidade Federal do Rio de Janeiro. Data on localities and host plants were obtained from the labels and information about the gall morphology (plant organ of occurrence, shape, and presence of trichomes) by observing the samples. The galling species was determined based on the literature. The collection includes 131 morphotypes of galls from Cerrado, obtained from 71 host plant species distributed in 50 genera and 30 botanical families (Table 1). All galls were collected in rupestrian fields (a rare vegetation physiognomy of the Brazilian Cerrado) in the state of Minas Gerais. As the collection comprises a great diversity of insect galls, it can be considered representative of this physiognomy.

"Quina" (Strychnos pseudoquina A. St. Hil) is a medicinal plant species from the Brazilian Cerrado. As its seeds show dormancy, they were subjected to the treatments pre-cooling at 5ºC during 7 days, pre-heating at 40ºC during 7 days, pre-soaking in sulfuric acid PA during 5 and 15 min, pre-soaking in boiling water during 5 and 15 min, pre-soaking in 100 and 200 ppm gibberellic acid during 48 h, pre-soaking in distilled water during 24 and 48 h, and mechanical scarification to break dormancy. Counts were daily conducted from the 2nd day after the experiment implementation until the germination stabilization at the 65th day. The germination speed index (GSI) and the germination percentage were evaluated. Germination rates above 96% were reached in seeds pre-soaked in water during 48 h and substrate moistened with water or KNO3.

Abstract:The present study aims to investigate the effects of vegetation structure (plant abundance and height) and soil characteristics (soil organic matter and macronutrients) on insect gall richness, and determine the extent to which these effects are mediated by the indirect effects of plant species richness. The study was performed in forty-nine 100-m2 savanna plots in Parque Nacional das Emas (Brazil) and sampled a total of 985 individual plants of 71 plant species and 97 insect gall morphotypes. Cecidomyiidae (Diptera) induced the most insect galls (38.1%), and the plant family Myrtaceae had the greatest richness of insect gall morphotypes (16). Path analysis of plant abundance, plant height, soil macronutrients, soil organic matter and plant species richness explained 73% of insect gall richness. The results show that soil macronutrient quantity has a direct positive effect on insect gall richness, whereas plant abundance and plant height had only indirect positive effects on insect gall richness via the increase in plant species richness. These findings showed that both plant-related and environment-related factors are important to induce insect gall richness in Neotropical savannas, and that plant species richness should be taken into account to determine the richness of insect galls.
