Replacement of CTV-susceptible sour orange rootstock by CTV-tolerant ones may have triggered outbreaks of Tetranychus urticae in Spanish citrus by Bruessow, F., Asins, María J., Jaques, Josep A., Urbaneja, Alberto

“…These results can explain, at least partially, the increasing prevalence of T. urticae as a pest in Spanish citrus orchards. Furthermore, problems could become much more severe on salt-tolerant rootstocks because of global warming, which is expected to exacerbate the threat of salinity, especially in areas with a semi-arid climate. © 2010 Elsevier B.V. …”

Patterns of ambulatory dispersal in Tetranychus urticae can be associated with host plant specialization by Aguilar-Fenollosa, Ernestina, Rey-Caballero, J., Blasco, José M., Segarra-Moragues, J. G., Hurtado-Ruiz, Mónica A., Jaques, Josep A.

“…Tetranychus urticae Koch (Acari: Tetranychidae) is a cosmopolitan and polyphagous species that may reach the pest status in many cropping systems including clementine orchards, where it may be found both in the trees and the associated flora. …”

Evaluation of plant-based water status indicators in mature apple trees under field conditions by Doltra, Jordi, Oncins, Jose Antonio, Bonany, Joan, Cohen, Moshe

“…However, MDS correlated well with ET0 and with midday Psi(stem) (R 2= 0.79) thus, making this parameter an interesting and promising tool for irrigation management in apple orchards. More research needs to be done in order to define reference values for MDS and plant water potential indicators, in relation to evaporative conditions and in different phenological periods, and to quantify the relationship between water status indicators values and apple tree yield and fruit quality.…”

Changes in predation and parasitism of the citrus leafminer Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) populations in Spain following establishment of Citrostich... by Karamaouna, F., Pascual-Ruiz, Sara, Aguilar-Fenollosa, Ernestina, Verdú, María J., Urbaneja, Alberto, Jaques, Josep A.

“…Because C. phyllocnistoides is an idiobiont parasitoid and preferentially parasitizes P. citrella second instars, this stage has become dominant in the orchards. The shift in the relative abundance of P. citrella larvae has prompted generalist predators to prey mostly on second instars and has contributed to the displacement of the native non-specific parasitoids, which principally utilize third instars, from the system. …”

“…For Italy, across the considered rates of radial range expansion the potential economic impact over 50 y ranges from 1.9 billion to 5.2 billion Euros for the economic worst-case scenario, in which production ceases after orchards die off. If replanting with resistant varieties is feasible, the impact ranges from 0.6 billion to 1.6 billion Euros. …”
