“…More significantly, an infestation of Eurosta solidaginis appeared to suppress volatile responses to a subsequent attack by a generalist caterpillar. Eurosta solidaginis apparently exerts control over host-plant defense responses that may reduce the predation risk for the gall inducer and any subsequent herbivores, and thus, could influence community-level dynamics, including the distribution of herbivorous insect species associated with S. altissima (Besten et al 2015). Similarly, a downregulation of host-plant defense responses by gall-inducing sawflies has been described (Nyman & Julkunen-Tiitto 2000).…”

Oak trees (Quercus) are hosts of diverse gall-inducing parasites, but the effects of gall formation on the physiology and biochemistry on host oak leaves is poorly understood. The influence of infection by four species from two widespread gall wasp genera, Neuroterus (N. anthracinus and N. albipes) and Cynips (C. divisa and C. quercusfolii), on foliage morphology, chemistry, photosynthetic characteristics, constitutive isoprene, and induced volatile emissions in Q. robur was investigated. Leaf dry mass per unit area (M A ), net assimilation rate per area (A A ), stomatal conductance (g s ), and constitutive isoprene emissions decreased with the severity of infection by all gall wasp species. The reduction in A A was mainly determined by reduced M A and to a lower extent by lower content of leaf nitrogen and phosphorus in gall-infected leaves. The emissions of lipoxygenase pathway volatiles increased strongly with increasing infection severity for all 4 species with the strongest emissions in major vein associated species, N. anthracinus. Monoterpene and sesquiterpene emissions were strongly elicited in N. albipes and Cynips species, but not in N. anthracinus. These results provide valuable information for diagnosing oak infections using ambient air volatile fingerprints and for predicting the impacts of infections on photosynthetic productivity and whole tree performance.

“…The interaction between Baccharis dracunculifolia and Baccharopelma dracunculifoliae has been widely studied in the last years (Fernandes et al, 2014;Arduin et al, 2005;Besten et al, 2014;Magalhães et al, 2013). Morphologically, galls are very similar, but there are some anatomical differences.…”

Anatomy, histochemistry, and comparative analysis of hydroxycinnamic derivatives in healthy leaves and galls induced by Baccharopelma spp. (Hemiptera: Psyllidae) in Baccharis spicata (Lam) Baill (Asteraceae)

Baccharis spicata is a plant native to the south of South America And is infected by psyllids of the Baccharopelma genus, which induce a fold gall in its leaves. This infection induces a series of anatomical and phytochemical variations compared to the healthy leaf: the content of total phenolic compounds and total hidroxycinnamic derivatives is lower, though the chlorogenic acid measured by HPLC remains the same and the 4,5 dichlorogenic acid content is near the half of the one observed in the one in the healthy leaf. Regarding to its anatomy, the gall has an homogeneous mesophyll and flavonoids in its outer epidermis compared to an isobilateral mesophyll and epidermal flavonoidic idioblasts observed in the leaf. The increase in the expression of waxes suggests it is a protective function against the desiccation by preventing water evaporation in the structure. The results here exposed suggest that the psyllid manipulates plant tissues, inducing hyperplasia and hypertrophy in the tissues, differentiating them from healthy structures and inducing changes in the biosynthesis of secondary polyphenolic metabolites that act like intermediary between the gall and the environment.

“…Galls are able to modify herbivore-induced responses against other herbivores due to changes in plant tissue, 37,50 but the VOC emission from gall-infested plants can vary greatly among species of galling insects on the same plant. 51 In Baccharis dracunculifolia, galls are induced by the psyllid Baccharopelma dracunculifoliae to produce 3.5% more VOCs than usual; 52 Pistacia atlantica galled by the aphid Slavum wertheimae produced approximately 2.5 times more volatiles than ungalled plants; and galls induced by the aphids Baizongia pistaciae on Pistacia palaestina exhibited independent metabolism producing and accumulating monoterpenes. 33 These examples emphasize the ability of galling insects to alter the biochemical function of the host plant, possibly protecting them against their own natural enemies.…”

Eavesdropping on gall–plant interactions: the importance of the signaling function of induced volatiles

The galling insect manipulates the host plant tissue to its own benefit, building the gall structure where it spends during most of its life cycle. These specialist herbivore insects can induce and manipulate plant structure and metabolism throughout gall development and may affect plant volatile emission. Consequently, volatile emission from altered metabolism contribute to eavesdropping cueing. Eavesdropping can be part of adaptive strategies used by evolution for both galling insects and the entire-associated community in order to cue some interaction response. This is in contrast to some herbivores associated with delayed induced responses, altering plant metabolites during the short time while they feed. Due to the different lifestyles of the galling organism, which are associated with different plant tissues and organs (e.g leaves, flowers or fruits), a distinct diversity of organisms may eavesdrop on induced volatiles interacting with the galls. Furthermore, the eavesdropping cues may be defined according to the phenological coupling between galling organism and host plant, which results from the development of a gall structure. For instance, when plants release volatile-induced defenses after galling insects' activity, another interactor may perceive these volatiles and change its behavior and interactions with host plants and galls. Thus, natural enemies could be attracted by different volatiles emitted by the gall tissues. Considering the duration of the life cycle of the galling organism and the gall, the temporal extent of gall-induced volatiles may include more persistent volatile cues and eavesdropping effects than the volatiles induced by non-galling herbivores. Accordingly, from chemical ecology perspective we expect that galling herbivore-induced volatiles may exhibit robust effects on neighboring-plant interactions including those ones during different plant developmental or phenological periods. Information about multitrophic interactions between insects and plants supports the additional understanding of direct and indirect effects, and allows insight into new hypotheses.
