Table 3 Summary of key-findings during a boosted SIT trial against Aedes albopictus in Vravrona, Attica Region, Greece, from May to November 2023 (5 exposure periods): Relative densities of eggs and adults (densities in the treated site divided by the average densities in the control site), egg hatching rates, competitiveness of boosted-SIT males, and boosted sterile-to-wild male ratio.

From: Suppression of the Asian tiger mosquito (Aedes albopictus) populations using the boosted sterile insect technique in Greece
