“…Studies that tested for an effect of total plant biomass on leaf and stem herbivores such as galling insects, which are specialised on a specific plant resource like young tissue of meristems, failed to detect any relationship (Espírito-Santo et al 2007). However, biomass of the respective component instead of total plant biomass showed a positive effect on these herbivores (Araujo et al 2006). This emphasises the importance of plant component biomass for feeding damage to a particular plant component.…”

“…Component biomass is composed of the number, size and mass density and is a measurement of the quantity of resources that can be expected to attract herbivores (Lawton 1983;Araujo et al 2006). Studies that tested for an effect of total plant biomass on leaf and stem herbivores such as galling insects, which are specialised on a specific plant resource like young tissue of meristems, failed to detect any relationship (Espírito-Santo et al 2007).…”

Plant size is a major predictor of ecological functioning. We tested the hypothesis that feeding damage to plants increases with plant size, as the conspicuousness of large plants makes resource finding and colonisation easier. Further, large plants can be attractive to herbivores, as they offer greater amounts and ranges of resources and niches, but direct evidence from experiments testing size effects on feeding damage and consequently on plant fitness is so far missing. We established a common garden experiment with a plant size gradient (10-130 cm height) using 21 annual Brassicaceae species, and quantified plant size, biomass and number of all aboveground components (flowers, fruits, leaves, stems) and their proportional feeding damage. Plant reproductive fitness was measured using seed number, 1000 seed weight and total seed weight. Feeding damage to the different plant components increased with plant size or component biomass, with mean damage levels being approximately 30 % for flowers, 5 % for fruits and 1 % for leaves and stems. Feeding damage affected plant reproductive fitness depending on feeding damage type, with flower damage having the strongest effect, shown by greatly reduced seed number, 1000 seed weight and total seed weight. Finally, we found an overall negative effect of plant size on 1000 seed weight, but not on seed number and total seed weight. In conclusion, being conspicuous and attractive to herbivores causes greater flower damage leading to higher fitness costs for large plants, which might be partly counterbalanced by benefits such as enhanced competitive/compensatory abilities or more mutualistic pollinator visits.

“…Studies conducted with gall-inducing insects were predominantly focused on factors aVecting gall abundance at the intraspeciWc level (Larson and Whitham 1997;Price 2003 and references therein; Araújo et al 2006;Rudgers and Whitney 2006). At the interspeciWc level, most studies analyzed only a small number of host plant species (Price et al 1996) or compared growth forms (herbs £ shrubs £ trees) (Fernandes and Price 1988;Price et al 1998a;Blanche and Ludwig 2001;Gonçalves-Alvim and Fernandes 2001;Lara et al 2002;Veldtman and McGeoch 2003;Cuevas-Reyes et al 2004).…”

Plant architecture and meristem dynamics as the mechanisms determining the diversity of gall-inducing insects

Plant architecture is considered to affect herbivory intensity, but it is one of the least studied factors in plant-insect interactions, especially for gall-inducing insects. This study aimed to investigate the influence of plant architecture on the speciose fauna of gall-inducing insects associated with 17 species of Baccharis. Five architectural variables were evaluated: plant height, number of fourth-level shoots, biomass, average level and number of ramifications. The number of galling species associated with each host plant species was also determined. To test the effects of plant architecture on gall richness at the individual level, we used another data set where the number of fourth-level shoots and gall richness were determined for B. concinna, B. dracunculifolia, and B. ramosissima every 3 weeks during 1 year. The average similarity between host species based on gall fauna was low (9%), but plants with the same architectural pattern tended to support similar gall communities. The most important architectural trait influencing gall richness at the species level was the number of fourth-level shoots, which is indicative of the availability of plant meristems, a fundamental tissue for gall induction and development. This variable also showed a positive correlation with gall richness at the individual level. We propose that variations in gall richness among host species are driven by interspecific differences in plant architecture via availability of young, undifferentiated tissue, which is genetically controlled by the strength of the apical dominance. Plant architecture should have evolutionary consequences for gall communities, promoting insect radiation among architecturally similar plants through host shift and sympatric speciation. We also discuss the role of plant architecture in the global biogeography of gall-inducing insects.

“…Literature on other plant models (e.g. Pistacia, Martinez and Wool 2003;Cotton, Anderson and Agrell 2005;Birch, Riihimäki et al 2006) can help identifying the underlying processes which include growth patterns: plant sectoriality (Araújo et al 2006;Larson and Whitham 1997;Marquis 1996;Orians and Jones 2001), habitat complexity (Finke and Denno 2006;Langellotto and Denno 2004;Lawton 1983) and connectivity (Hanan et al 2002;Skirvin and Fenlon 2003). In apple, which is one of the most documented fruit tree production, effects of tree architecture were reported on codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), (Simon et al 2007b;Stoeckli et al 2008a) and the rosy apple aphid (RAA), Dysaphis plantaginea (Passerini) (Hemiptera: Aphididae) (Simon et al 2006).…”

Période 2000-2012. http://prodinra.inra.fr/record/256699Plant architecture highly constrains pest infestation but is rarely considered in studies on plant–insect interactions. We analysed the relationships between apple tree architectural traits manipulated by tree training and within-branch development of Dysaphis plantaginea (rosy apple aphid, RAA),a major apple pest,during its multi- plication wingless phase in spring. We hypothesised that the degree of branching had an effect on RAA within-branch estation. In an experimental apple orchard, the infestation by aphid wingless forms was surveyed in two consecutive spring seasons within branches manipulated to design contrasted architectures differing in shoot numbers, shoot density and branching orders. Whatever the branch management system, aphid infestation was higher on long versus short, fruiting versus vegetative, and growing versus non-growing shoots. Either less infested shoots or less severe infestation were observed in the most branched system. A pattern of within-branch short-distance infestation was conﬁrmed. Moreover, the number of branching points between two shoots exerted a high constraint on this infestation pattern. Beside possible trophic effects due to plant growth patterns already documented in the literature, a high degree of branching is likely to be a key-architectural trait to constrain within-branch aphid infestation. This opens new perspectives on the manipulation of branch architecture as a mean giving partial control of pests towards sustainable fruit production
