“…The highest infestation of long growing and fruiting shoots of our study is also related to well-known trophic relationships. This result is consistent with the preferential development of fruit tree aphids on growing shoots (Grechi et al 2008) and more especially when they are long (Stoeckli et al 2008b) in the peach-Myzus persicae (Sulzer) (Aphididae) and apple-A. pomi cases studies, respectively.…”

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

“…Two major genes for woolly apple aphid resistance were mapped to the upper part of LG8 in apple (Bus et al 2008(Bus et al , 2010, the same region where we detected the major QTL for psylla resistance. Moreover, the putative QTL for the resistance of apple to A. pomi found on LG11 by Stoeckli et al (2008a) co-localizes with the smalleffect QTL that we detected on this LG for total nymphs. This is not the first time that loci associated to psylla and aphid resistance are found in chromosomal regions orthologous between species: aphid resistance genes were mapped to LG17 in both pear (Evans et al 2008) and apple (Stoeckli et al 2008b;Bus et al 2008Bus et al , 2010, where Bouvier et al (2011) also detected a QTL for pear psylla resistance in the P. ussuriensis × P. communis hybrid NY10355.…”

“…To our knowledge, only one other study focused on mapping pest resistance loci in pear: Evans et al (2008) mapped a major gene for resistance to Dysaphis pyri to LG17 of the snow pear (Pyrus nivalis). In contrast, in the apple (Malus × domestica) genome, several loci linked to insect resistance, especially to aphids, have been mapped: a resistance gene and a QTL for the leaf-curling aphid (Dysaphis devecta (Walker)) on LG7 (Roche et al 1997;Cevik and King 2002;Stoeckli et al 2008b); a QTL for the rosy apple aphid (Dysaphis plantaginea (Passerini)) resistance on LG17 (Stoeckli et al 2008b); a QTL for antibiosis resistance to the green apple aphid (Aphis pomi De Geer) on LG11 (Stoeckli et al 2008a); four major genes conferring resistance to woolly apple aphid (Eriosoma lanigerum (Hausmann)) on LGs 7, 8, and 17 (Bus et al 2008(Bus et al , 2010; and a QTL associated with the carpophagous codling moth (Cydia pomonella L.) susceptibility on LG10 (Stoeckli et al 2009). …”

Cacopsylla pyri (pear psylla) is one of the most serious pests of pear (Pyrus spp.) in Europe. It can cause high yield losses, and its control has become difficult since it has developed resistance to a wide range of pesticides. Pear breeders are developing new cultivars resistant to pear psyllids, and Asian species, such as Pyrus ussuriensis and Pyrus × bretschneideri, are good sources of resistance. Antixenosis and antibiosis resistance to psylla were both identified in pear; they may differ in the biological mechanism and probably have different genetic backgrounds. We crossed interspecific P. × bretschneideri × Pyrus communis hybrid PEAR3, resistant to pear psylla, with the susceptible European pear cultivar 'Moonglow' to obtain an F1 population for the genetic mapping of the resistance. Quantitative trait locus (QTL) analysis was carried out for antibiosis by measuring the number of surviving nymphs and the nymphal development, using a novel phenotyping protocol and a saturated genetic map made of single-nucleotide polymorphism (SNP) and microsatellite (simple sequence repeats (SSR)) markers. A stable QTL was detected on linkage group (LG) 8 of PEAR3 (R 2 =17.2-39.1 %). In addition, QTLs were detected on LG5 (R 2 = 10.8 %) of PEAR3 and on LG15 of 'Moonglow' (R 2 = 13.7 %).

Crop plant domestication can change plant resistance to herbivores leading to differences in pest pressure experienced by crop plants and their wild relatives. To compare resistance to herbivores between domesticated and wild fruit trees, we quantified direct resistance and indirect resistance to a pest insect, the florivorous apple blossom weevil Anthonomus pomorum (Coleoptera: Curculionidae), for the cultivated apple Malus domestica and two wild apple species, the European crab apple M. sylvestris and the exotic M. kirghisorum. We measured weevil infestation and performance (weight, sex ratio), and weevil parasitism by parasitoid wasps for different cultivars of M. domestica and for the two wild apple species. To explain weevil and parasitoid responses to different apple species, we quantified tree characteristics including nitrogen content, size of flower buds, bark roughness, tree size, tree phenology and tree position. We found significant differences in susceptibility to weevil infestation between apple species, with lowest infestation (highest apple resistance) in M. domestica and highest infestation in M. kirghisorum. The suitability of apple species also varied significantly: weevils emerging from M. sylvestris were significantly lighter than those from M. kirghisorum. Parasitism of A. pomorum by different parasitoid species was significantly higher in M. sylvestris than in M. domestica. Infestation, weevil weight and parasitism were positively related to tree characteristics: infestation to bud nitrogen content and bark roughness, weevil size to nitrogen content and bud size, and parasitism to tree height and bud density. Our study revealed marked differences between apple species in susceptibility and suitability for the pest herbivore, but also for antagonistic parasitoids. Whereas direct resistance appeared to be higher in cultivated apple, indirect resistance via parasitoids was apparently higher in wild apple trees. Our findings suggest that wild and cultivated apple trees possess different resistance traits that may be combined to optimize resistance in commercial apple cultivars.
