Résumé
To prepare for a boosted sterile insect technique (SIT) field trial in Saint-Joseph, Reunion island, we compared the attractiveness of two adult mosquito traps for
and
. In addition, we explored the co-occurrence of these species in their usual larval habitats. Two traps were compared with two conditions each using a Latin square design: BG Sentinel trap baited with carbon dioxide (CO
) with/without addition of BG Lure and ovi-sticky trap with/without hay. The ovi-sticky traps proved ineffective. For both
species, CO
-baited traps were equally effective at catching females when baited with the lure or not. In contrast, they were more attractive to males than for females with the lure.
larvae were found in four of six vacoas (
), and one of four anthropogenic breeding sites. In vacoas, the densities of
and
larvae were negatively correlated, whereas the correlation was positive between chironomids and
. The abundance of adults and larvae varied according to weather conditions. Finally, CO
-baited traps were used without lure for the entomological monitoring to assess the effectiveness of the area-wide boosted SIT intervention to reduce costs and logistics.
