Short answer
Several possible studiesNo clear answer.
More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 6Not checkedRising temperatures and longer warm seasons are helping mosquitoes spread West Nile virus across a wider area in Italy and during more months of the year.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 6Not checkedMore than 650 infections have been reported in Italy so far this year, accounting for roughly half of all cases recorded in Europe, according to local health authorities.View evidenceHide evidence
As statedmore than 650 infections; roughly half of all cases in Europe
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 6Not checkedAntonino Bella said higher temperatures linked to climate change help mosquitoes reproduce and extend the transmission season, increasing the chances that infected mosquitoes will spread the virus to people.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 6Not checkedBella said the transmission season can sometimes last as late as November, and areas once largely unaffected are increasingly reporting infections, suggesting a gradual expansion of the virus across Italy.View evidenceHide evidence
