“…Tree species are often architecturally more complex, more apparent to insects (sensu Feeny, 1976) and usually produce larger fruits and/or seeds than congeneric shrubs (Moles & Westoby 2006; Fagundes et al 2013; Ágnes‐Júlia et al, 2022). In addition, female EPIs must locate larger seeds for oviposition to ensure highest success of their offspring (Canto et al, 2019; Celis‐Diez et al, 2004; Cope & Fox, 2003; Souza & Fagundes, 2017).…”

“…Although many studies have suggested that the architectural complexity and appearance of plants (e.g., Fagundes et al, 2013; Ferreira et al, 2022; Ramírez & Traveset, 2010) and seed mass (e.g., Azcárate et al, 2010; Foffová et al, 2020; Gripenberg et al, 2019; Palmer et al, 2022; Souza & Fagundes, 2017) positively drive host plant selection and seed predation by insects, other aspects involving the plant‐EPI interaction can also affect this relationship. For example, the pattern of resource distribution in the landscape (Abdala‐Roberts et al, 2010; Rossi et al, 2011; Pardini et al, 2017; Weissflog et al, 2017; Kuchenbecker & Fagundes, 2018; Coutinho et al, 2019) and the dispersal ability of herbivores (Otway et al, 2005; Rossi et al, 2011) might also explain variation in insect attack on their host plants.…”

Characterising host selection mechanisms and the performance of seed‐predating insects on different hosts has broad implications for ecology and applied entomology. We assessed host selection and performance of endophagous seed‐predating insects on three species of Copaifera, testing two hypotheses: (i) large‐sized trees produce larger seeds and have higher levels of seed predation than their smaller congeneric relatives, and (ii) endophagous seed‐predating insects that develop in larger‐seeded trees exhibit higher body mass, lipid content, and muscle mass as they obtain higher amount of food resources. Unpredated seeds of the large‐sized Copaifera langsdorffii showed greater mass than their smaller congeneric relatives C. arenicola and C. oblongifolia. Two species of endophagous seed‐predating beetles (Rhinochenus brevicollis and Apion sp.) were found attacking seeds of the three Copaifera species. Rhinochenus brevicollis preyed on a higher percentage of seeds than Apion sp. The shrub C. oblongifolia had the highest percentage of seed predation, contradicting our original hypothesis that larger species have a higher percentage of seed predation. Rhinochenus brevicollis preyed on a higher percentage of seeds of larger‐sized species than Apion sp. The higher dispersal ability of R. brevicollis associated with different patterns of plant species distribution may be the mechanism driving differential seed predation among Copaifera species. Adult insects that emerged from C. langsdorffii seeds showed higher body mass and lipidic content. It is likely that insects developing in larger seeds obtain a higher amount of food resources during their development. Finally, we observed a positive relationship between body weight and lipidic content in adults of R. brevicollis. We suggest that studies shedding light onto insect performance in different host‐sized seeds are necessary to understand host selection by beetles.

Neotropical Insect Galls

Super-host plants of galling insects are important systems for hypotheses testing. Plant phenology directly affects the gall community through the synchronism between the target organs development and insect attack, or indirectly by promoting changes in plant resource quality and/or quantity. This study focus on the effects of inter-and intra-annual variations in plant phenology on the galling insect community associated with the host plant Copaifera langsdorffi i . The species C. langsdorffi i is a super-host of galling insect that have supra-annual fruiting and broadly intra-annual variation in phenology. Supra-annual fruiting affected the resource allocation among vegetative growth, reproduction and production of chemical defenses. The galling insect community changed between reproductive and non-reproductive years of C. langsdorffi i. Moreover, leaf biomass and gall richness and abundance were also affected by intra-annual variation in plant phenology. Finally, the possible roles of plant phenology on gall community associated with C. langsdorffi are discussed.
