Background  Entomopathogenic fungi are highly promising agents for controlling  Aedes aegypti  mosquitoes. Deploying fungus-impregnated black cloths in PET traps efficiently reduced  Ae. aegypti  female survival rates under intra-domicile conditions. With the aim of further increasing the effectiveness of the traps, the addition of attractive lures to fungus-impregnated traps was evaluated.    Methods  Black cloths were suspended inside 2 l plastic bottles called “PET traps”. These traps were placed in rooms simulating human residences. The first experiments evaluated the attraction of mosquitoes to PET traps with black cloths covered in adhesive film with and without synthetic lures (Atr Aedes ™). Traps were left in the test rooms for either 24 or 48 h. The attractiveness of the lures over time was also evaluated. The efficiency of PET traps with fungus-impregnated black cloths associated with lures was compared to that of traps without lures.    Results  The highest percentage of captured mosquitoes (31 and 66%) were observed in PET traps with black cloths covered in adhesive film + attractive lure maintained in test rooms for 24 h and 48 h, respectively. Black cloths covered in adhesive film captured 17 or 36% of the mosquitoes at 24 h and 48 h, respectively. The attractiveness of the lures fell gradually over time, capturing 37% after 5 days on the bench and 22% of the mosquitoes after 30 days exposure to ambient conditions. Associating attractive synthetic lures with black cloths impregnated with  M. anisopliae  placed in test rooms for 120 h reduced mean survival to 32%, whilst black cloths impregnated with  M. anisopliae  without lures resulted in a 48% survival rate. Using  Beauveria bassiana  in the traps resulted in a 52% reduction in mosquito survival, whilst combining  Beauveria  and Atr Aedes  resulted in a 36% survival rate. PET traps impregnated with fungus + Atr Aedes  resulted in similar reductions in survival when left in the rooms for 24, 48, 72 or 120 h.    Conclusions  Atr Aedes  increased attractiveness of PET traps with black cloths under intra-domicile conditions and when associated with  M. anisopliae  or  B. bassiana , significantly reduced  Aedes  survival. This strategy will reduce the number of PET traps necessary per household.
