Observed density (graphs a, c, e), and observed relative density (graphs b, d, f) of Aedes mosquitoes (\(\log _{10}\) scale) sampled during three boosted SIT trials in La Reunion (site 1) (treated site \(n=7\) traps/collection day, vs. control site \(n=5\)), from March to July 2021 (La Reunion (site 1): graphs a, b), La Vilavella (site 2) (\(n=35\) vs. \(n=20\)) (Spain: graphs c, d), and Polinyà de Xúquer (site 3) (\(n=23\) vs. \(n=55\)) (Spain: graphs e, f), from June to October 2021. Eggs were a mixture of Aedes albopictus and Aedes aegypti in La Reunion, and Aedes albopictus alone in Spain. The observed relative density was the observed density in traps located in the treated site, divided by the expected density, i.e., the average density in the control site. For adults, the violin plots represented the probability density of Aedes aegypti in La Reunion, and Aedes albopictus in Spain. Eggs were sampled with oviposition traps. In La Reunion (site 1), adults were sampled with BG-Sentinel traps; in Spain, they emerged from the eggs collected with oviposition traps. In each site, the same number of traps were used for eggs and adults.
