Previously, quick assessments of the potential for establishment in Sweden were done for 82 quarantine pests for which there had been uncertainty about whether the ecoclimatic conditions and host availability allowed the establishment (Björklund and Boberg 2021; 2023). 

SLU Risk Assessment of Plant Pests was requested by the Swedish Board of Agriculture to apply the same methodology for conducting quick assessments for the following provisional quarantine pests: Chloridea virescens, Homona magnanima, Resseliella citrifrugis and Spodoptera ornithogalli. The results are presented in this risk assessment.
