Dengue, Chikungunya, and Zika are important vector-borne diseases, andAedes aegyptiL. is their main transmitter. As the disease management is mainly based on mosquito control strategies, the search for alternative and cost-effective approaches is ongoing. The Gram-negative bacteriaXenorhabdus nematophilaandPhotorhabdus luminescensare symbiotically associated with entomopathogenic nematodes and are highly pathogenic for insect larvae. After we have recently confirmed the toxicity of these bacteria inAe. aegyptilarvae, we here evaluated the toxic activity of culture fluids on the development of this mosquito species. Larval susceptibility was assessed by exposing larvae to different concentrations ofP. luminescensorX. nematophilaculture fluids to confirm whether secondary metabolites might cause the mosquitos’ death.Xenorhabdus nematophilaculture fluid was more effective and stable during the mosquito pathogenicity bioassays compared to that ofP. luminescens. Larval mortality started a few hours after exposure of the insects to the fluids. Furthermore, the residual effect of larvicidal activity ofX. nematophilafluid persisted at full efficiency for 4 d. Particularly, larval mortality was still higher than 50% for up to 8 d. Exposure of larvae to a sublethal dose ofX. nematophilafluid delayed pupation as well as emergence of adult mosquitoes and caused cumulative larval mortality higher than 90% by day 14. Here, we describe for the first time the use of stable culture fluids and therefore secondary metabolites ofP. luminescensandX. nematophilaas a promising basis for the use as biopesticide for control ofAe. aegyptiin the future.
