“…In descending order, gall morphotypes appeared in Fabaceae (N = 11), followed by Euphorbiaceae (N = 7), Information about morphotype richness of other families and species is given in Table 2. Our results indicated that the richer the host family, the richer their gall morphotypes, corroborating data previously obtained in the Neotropical region (Gagné, 1994;Araújo, 2011;Santana & Isaias, 2014). However, it's important to highlight that of the 41 morphotypes sampled, 23 were found in the four host plant species: Copaifera langsdorffii, Croton floribundus, Diplopterys pubipetalum, and Bauhinia holophylla, with eight, seven, five and three morphotypes, respectively.…”

Herein, we studied the occurrence of insect galls from natural vegetation around the Itambé Cave, Altinópolis, SP, Brazil. A sampling effort of 7.5 hours resulted in 41 gall morphotypes on 21 host plant species from 14 families. The richest families of host plants in morphotypes were Fabaceae (N = 11), Euphorbiaceae (N = 7), and Malpighiaceae (N = 5). Copaifera langsdorffii Desf. (N = 8), Croton floribundus Spreng. (N = 7), Diplopterys pubipetala (A. Juss.) W.R. Anderson & C.C. Davis (N = 5), and Bauhinia holophylla (Bong.) Steud. (N = 4) were the super host plant species. Among the gall makers obtained, cecidomyiids were reared in 81% of cases and Hemiptera (Diaspididae), Hymenoptera (Eurytomidae), Coleoptera (Apion sp./Apionidae), and Lepidoptera in 4.5% of cases, each. The parasitoids belong to the Chalcidoidea superfamily (Hymenoptera). One new species of Camptoneuromyiia (Cecidomyiidae) was found in Smilax oblongifolia Pohl ex Griseb. (Smilacaceae) as inquiline and a new species of Lestodiplosis in Diplopterys pubipetala (Malpighiaceae) was a predator. We also present the first register of Bauhinia holophylla as host plants of Cecidomyiidae, and we expand the occurrence of Rochadiplosis tibouchinae Tavares and Couridiplosis vena to São Paulo State. The results of this paper are a continuation of the description of gall morphotypes from the vegetation in Northeastern São Paulo State, and they also increase knowledge about the diversity of host plant and gall-maker associations in the Neotropical region.

“…Leaves comprised the organ with the greatest richness of galls, corroborating the pattern observed in numerous other Brazilian ecosystems (e.g., Coelho et al 2009;Almada and Fernandes 2011;Maia 2013a, b;Maia and Souza 2013;Maia 2014;Santana and Isaias 2014). High gall richness on leaves may be explained by their high morphological plasticity and their roles as photosynthetic organs (Mani 1964;Formiga et al 2014;Maia 2014).…”

Insect galls and their host plants in gallery forest in Bahia State, Brazil

et al. 2020

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.

Background: The term ‘super host’ plant is often used in the literature surrounding plant-galling interactions, but the different contexts in which the term is used generates doubt and confusion due to the absence of a systematic definition of the term’s meaning. Objective: In this study, we used 60 well-defined plant-galling assemblages to propose a systematic definition of super-host plants at the local and regional level. In addition, we investigated factors that explain the number of galling species per host plant at different geographic scales. Methods: Plant-galling assemblages were compiled from an extensive literature review on insect gall inventories carried out in Brazil. Results: We found 888 host plant species belonging to 94 families and 340 genera hosting 2,376 insect gall morphotypes. At a local scale, 33.2% of host plant species harbored one insect gall morphotype and 12.2% hosted two gall morphotypes, making up 45.4% of the host plant species in each locality. At the regional scale, 51.5% of host plant species harbored one insect gall morphotype, and 17.9% of host plant species hosted two gall morphotypes, corresponding to 69.4% of all host plant species. Based on the average number of galling species per plant species, we classified the plant species into: 1) Host species; 2) Multi-host species and 3) Super-host species. The super-host plant species that showed the greatest richness of gall morphotypes at the local level were Baccharis reticularia and Adenocalymma neoflavidu. Furthermore, we found a positive relationship between plant life-form architectural complexity and the number of galling species at the local level. At the regional scale, we registered five super-host species (Guapira opposita, Protium heptaphyllum, Copaifera langsdorffii, Myrcia splendens, and Byrsonima sericea) which hosted 21 or more insect gall morphotypes. The number of galling species per host plant species at the regional scale was influenced positively by geographic distribution rank and number of biomes in which each species of the plant occurs. Conclusion: The present study stands out as the first of its kind to provide a systematic standardization for the super-host plants and to investigate factors influencing these species.
