“…By demonstrating that the performance and possibly also the preference of the florivorous weevil A. pomorum differ among apple cultivars, the present study may help to identify plant traits that should be studied more intensively to better understand tree resistance to florivores. Such information on tree characteristics that contribute to tree resistance to florivores may be used for breeding resistant fruit tree cultivars (Stoeckli et al ., ; Kumar et al ., ) and for interfering with herbivore population development (Greenberg et al ., ). Because the detected differences in performance of florivores developing on different cultivars may also affect natural enemies of the florivores such as parasitoids (Hardy & Ode, ; Mody et al ., ), our findings support other studies that highlight the need to consider combined bottom‐up and top‐down approaches for increasing sustainability in orchards (Zehnder et al ., ; Simon et al ., ).…”

1 Plant resistance strongly depends on plant characteristics that affect herbivore preference or performance. Different plant genotypes may express specific characteristics that lead to differential resistance to herbivores. Few studies have investigated these aspects for weevils, a particularly speciose taxon of insect herbivores, on fruit tree cultivars, which are vegetatively propagated. 2 We studied the influence of apple cultivar on preference and performance of a fruit tree herbivore, the flower-feeding apple blossom weevil Anthonomus pomorum (Coleoptera: Curculionidae). We quantified field infestation of five different apple genotypes by the weevil at different collection dates as measure of preference, as well as the mass and emergence time of weevils developing on these cultivars as measures of performance. 3 Infestation of apple flower buds by A. pomorum differed significantly between cultivars. The collection date affected the number of infested flowers in a cultivar-specific way. 4 Weevil mass differed significantly between apple cultivars. The average mass of weevils from Ariwa, the cultivar producing the heaviest weevils, was 40% higher than the mass of weevils from Rewena, the cultivar producing the lightest weevils. 5 Weevil emergence time from infested flowers differed significantly between cultivars.Weevils emerged earliest from cultivars Ariwa and Retina, at an intermediate time from Discovery and Florina, and latest from Rewena. 6 The present study demonstrates that preference and performance of florivores feeding on fruit trees can strongly differ between apple cultivars representing specific tree genotypes. These differences may directly and indirectly affect herbivore and antagonist populations and can be considered for pest management.

The superfamily of the Eriophyoidea is a large and diverse group of mites, including a number of species of economic importance, mainly on perennial plants in agriculture and forestry. This review focuses on the economic importance and pest status of this group of mites, with emphasis on some genera. The available acaricide portfolio is reviewed and the influence of EU legislation policy on the sustainable control of Eriophyoidea is investigated. Possible generic guidelines for sustainable control and resistance management with special reference to the European situation are discussed. Recent advances in biological and integrated control of eriophyid mite pests and the implementation of these techniques in crops are explored. Furthermore, the relevance of studies on behaviour, epidemiology and diagnostics in general terms and as a strategic necessity is pointed out.

The high economic losses caused by the occurrence of iron chlorosis in Prunus orchards in the Mediterranean area justifies the implementation of breeding programs to generate high-performance rootstocks for different edaphoclimatic area conditions. For that reason, the genetic control of iron chlorosis tolerance was studied in an F 1 population derived from a three-way interspecific cross between a Myrobalan plum ("P 2175") and an almond x peach hybrid ("Felinem"). Several phenotypic measures were assessed to guarantee an accurate data set for genetic analysis. SPAD values, chlorophyll concentration, and visual diagnostic symptoms were highly correlated with leaf chlorosis in trees. SPAD value was the most reliable measure, since it was an objective, unbiased, and non-destructive method. Two significant quantitative trait loci (QTLs) involved in SPAD and chlorophyll concentration were identified for "Felinem" in linkage groups 4 and 6. Both QTLs were detected in four of the six consecutive years of the experiment. For "P 2175", two of the three putative QTLs identified, pspad4.1 and chl4.1, were placed in linkage group 4. These QTLs were related to the SPAD values and chlorophyll concentration, respectively, and co-localized with QTLs detected in the "Felinem" map affecting the same traits. Candidate gene PFIT, related to iron metabolism, was localized within the confidence interval of the QTL in linkage group 4. This research suggests an association of this chromosome region with tolerance to iron chlorosis in Prunus, and it provides a first approach to localize candidate genes involved in tolerance to this abiotic stress.
