Distribution and dispersal of the invasive Asian chestnut gall wasp, Dryocosmus kuriphilus (Hymenoptera: Cynipidae), across the heterogeneous landscape of the Iberian Peninsula

Abstract

http://www.eje.cz 2010), modifying plant architecture (Gehring et al., 2017) and even rarely negatively affecting the survival of trees (Payne et al., 1975). This cynipid is distributed in different regions around the world where chestnut forests are present, such as Japan (Oho & Umeya, 1975), North America (Payne et al., 1975) and Europe (Brussino et al., 2002). Gall wasp proliferation and invasiveness in newly colonized areas is facilitated by the absence of natural enemies (Stone et al., 2002). Despite the recruitment of numerous indigenous parasitoids by D. kuriphilus after its arrival in Europe, which shifted onto this new resource from the Cynipini parasitoid communities on oaks, none were able to control this invasive species (

Can Niche Dynamics and Distribution Modeling Predict the Success of Invasive Species Management Using Biocontrol? Insights From Acacia longifolia in Portugal

“…The evidence for niche expansion may also reflect the low number of occurrence records for T. acaciaelongifoliae in Australia, which thus fail to fully represent the realized niche. Gall-forming insects, particularly in native regions where they coexist with their hosts often in equilibrium, are frequently overlooked and understudied organisms, despite the importance of several species as biocontrol agents (Dennill, 1988;Harris and Shorthouse, 1996) or pests (Gil-Tapetado et al, 2018;Ferracini et al, 2019). This resulted in a relatively reduced dataset in Australia, vulnerable to spatial biases, which are known to affect niche estimates (Graham et al, 2008;Sánchez-Fernández et al, 2011).…”

“…Gall development occurs concomitantly with budbreak and leaf expansion, and the dissemination of the infestation is assisted through the flight of the adults, estimated to have a range of about 6.6 km/year . In Spain, ACGW was first reported in 2012 in the Catalonia region and it has rapidly spread to other geographically distant Spanish chestnut‐growing areas …”

“…9 In Spain, ACGW was first reported in 2012 in the Catalonia region 10,11 and it has rapidly spread to other geographically distant Spanish chestnut-growing areas. 12 In terms of phytosanitary measures to control ACGW, insecticides have been proven ineffective because of the difficulty of reaching the larvae inside the bud. In addition, their serious environmental effects and the high risk of their use killing pollinators as well as the potential for chemical residues in honey have to be considered, as well as their considerable economic costs.…”
