“…The oviposition in near sites leading to the fusion of plant tissues does not appear as a main strategy of galling herbivores. Also, this gall shape had been referred as amorphous galls, and its coalescent nature was firstly reported by Isaias et al (2013) for less than 0.5 % of galls documented in the inventories. Alternatively, such confronting data may be result of underestimating field sampling or lack of standardization of nomenclature (i.e.…”

“…This capacity is neither linked to the host plant species nor to the environmental stresses; for these four geometrical final shapes also common on other host species were inventoried in other Brazilian biomes (i.e. Isaias et al, 2013).…”

“…The globoid is, indeed, one of the most common gall morphotype in Brazilian flora, quoting for about 27 % of the total galls listed by Isaias et al (2014). Nevertheless, the lenticular morphotype quotes for about 2 % of the galls recorded in the inventories checked by Isaias et al (2013;. In the ASP, together with the marginal intumescence and the conical morphotypes, the lenticular and globoid galls depict for the high morphogenetic potential of the host plants to respond to distinct galling stimuli.…”

“…The identification of the galling insects was based on the revision of galls from the Southeastern Brazil (Maia, 2013). The gall morphotypes were classified according to Isaias et al (2013), and photographed under a desk magnifier (model Toyo TL1020, 5 times magnifying lenses), with the aid of a digital camera, model Samsung ES68. …”

“…Galls are plant structures that protect and nurture the larvae of the gall -inducing insect (Abrahamson & Weis, 1987;Fernandes & Price, 1991;Fernandes & Price, 1992;Raman, Schaefer, & Withers, 2005;Shorthouse, Wool, & Raman, 2005) which consist of a wide and taxonomically unknown fauna of galling herbivores in species-specific interactions, resulting in closely related morphotypes (Isaias, Carneiro, Oliveira, & Santos, 2013;Isaias, Carneiro, Santos, & Oliveira, 2014). These morphotypes are representative of the diversity of the inducing insects (Floate, Fernandes, & Wilson, 1996;Carneiro et al, 2009), which should also be associated with a diversity of insects at other tropic levels (Dreger-Jauffret & Shorthouse, 1992;Stone & Schonrogge, 2003).…”

Abstract:The Atlantic Coast Restinga is a mosaic of plant communities with a distinct floristic and phytophysiognomy, exposed to luminous, thermal, and saline stresses. Plants of the restinga must have special features commonly associated to xeric environments, and are expected to host a high diversity of galling herbivores. We studied gall morphotypes, and recorded the diversity of galls on plants growing in sand dunes in a remnant area of restinga (Acaraí State Park) in São Francisco do Sul, Santa Catarina State, Brazil. The sampling was done in four plots (250 x 5 m), constituting a total area of 5 000 m², during April, May and June. Plant branches (n ≥ 5) with galls were sampled, identified, and the galls were photographed. The galls were classified into eight morphotypes, associated to eight host plants constituting 15 host plants -galling herbivores systems. The identification of the gall -inducers was based on literature, and on the species-specific feature of this kind of host plant-gall inducers interaction. There was a predominance of leaf galls, green in color. The most common morphotypes were the globoid, lenticular, conical, rosette, marginal, and fusiform galls, similarly to the inventories performed on other Brazilian biomes. Despite the environmental stresses, the xeric features of the dunes of the ASP, and the high local plant diversity, the diversity of galling herbivores were low. Varronia curassavica (Boraginaceae), Smilax campestris (Smilacaceae), and Guapira opposita (Nyctaginaceae) were superhosts of galling herbivores in the dunes, with about 70 % of the total associated parasites. The environmental effect seems to be neutral, either for the host plants or for the generation of gall morphotypes. Alternatively, the scarce nutritional resources could be restrictive for the establishment of the galling herbivores inside plant tissues. Rev. Biol. Trop. 63 (4): 959-970. Epub 2015 December 01.

Premise Gall‐inducing organisms change the development of their host plant organs, resulting in ontogenetic patterns not observed in the non‐galled plants. Distinct taxa induce galls on Schinus spp., manipulating meristematic patterns in the host plant in distinct ways. Here we report ontogenetic novelties induced in the lateral buds of S. engleri by Eucecidoses minutanus, a Cecidosidae, whose galls have been poorly understood. Methods The anatomy, histochemistry, and histometry of galls in distinct phases of development, non‐galled buds, and stems of Schinus engleri were analyzed in parallel with the instars of E. minutanus to detail the morphogenetic changes in the host with each larval stage. Results Ontogenetic phases of the galls were intricately associated with larval development. First and second‐instar larvae induced pericycle and pith cells to dedifferentiate into the gall inner meristem, where hyperplasia and cell hypertrophy characterized the growth and development phase of the gall. The innermost layers were lipid‐rich nutritive cells that lined the larval chamber. Additional vascular bundle rows were produced in young galls. Third and fourth instar‐larvae were associated with the gall maturation phase: centripetal lignification of the outer parenchyma cell layers, epidermal stratification, and activation of a cambium‐like meristem (CLM). The CLM activity resulted in new layers of nutritive cells that differentiated inward as the first layers of nutritive cells were consumed by E. minutanus larvae, and, also, in more parenchyma cell layers that formed outward. All tissues between the innermost layer of nutritive tissue that surround the gall chamber and the outermost layer of the dermal system that externally covers the gall form the gall wall, and increased in thickness until the end of gall maturation. Conclusions E. minutanus induces a structurally complex globoid stem gall, modifying all host plant tissues and stimulating a novel meristematic pattern in S. engleri. The gall developmental stages are each related to specific gall‐inducing instars, as gall development progresses according to the development of E. minutanus.
