We are witnessing a veritable invasion of tiger mosquitoes in southern regions of France and of Europe. They are not only harmful, but also pose a health hazard. They are vectors of diseases such as dengue, chikungunya and Zika virus.

Cases of dengue (178 cases[1] in Occitanie[2] in 2024[3]) and chikungunya have been reported in southern France[4]. In 2023, 82 indigenous dengue cases were reported in Italy[5], and the species has spread to all regions of Romania[6] and Spain[7], even to the most inland areas such as Aragon or Madrid[8].

Municipalities must carry out investment plans: install mosquito traps[9], eliminate stagnant water or introduce natural predators of the tiger mosquito[10].

In view of the above:

  • 1.Does the Commission intend to unlock funds to enable affected European municipalities to invest in measures to combat the tiger mosquito?
  • 2.Will it support the measures to combat the health risk posed by tiger mosquitoes, in particular by releasing sterilised males to prevent their reproduction[11]?
  • 3.Does it intend to launch a European plan to combat tiger mosquitoes – which have been ravaging the southern regions of Europe for many years – in particular through mosquito eradication measures?
