“…Therefore, DMT treatment triggered an increase in the Pseudomonadaceae density in the parent-generation aphids (G0) that were directly exposed to the sublethal DMT, whereas this stimulating effect disappeared in the next generation. Pseudomonadaceae helps the host in detoxifying toxic plant allelochemicals and pesticides, which can promote the adaptive ability of Dendroctonus ponderosae to terpene-rich trees via degrading terpenes and result in a strong degradation and detoxification effect on profenofos . Overall, the above results related to the changes in the bacterial community abundance of A.…”

In aphids, hormesis and symbiotic bacteria are the drivers for the development of pesticide resistance. However, the related mechanism remains unclear. Here, we evaluated the sublethal and transgenerational effects of the extensively used pyrethroid pesticide deltamethrin (DMT) on the population dynamics in Aphis gossypii and tested its influence on symbiotic bacterial communities. The leaf-dip bioassay revealed that DMT was highly toxic to A. gossypii, and at a low lethal concentration of DMT, the intrinsic (r) and finite rates of increase (λ) of the initially exposed aphids (G0) significantly decreased. Intriguingly, the r, λ, and net reproductive rate (R 0) of G1 and G2 significantly increased, but the r and λ decreased in G3. The adult and total preoviposition period increased in G3 but decreased in G4. Additionally, the diversity of the bacterial community decreased, while the abundance values of Buchnera, Pseudomonadaceae, and Burkholderiaceae increased after 24 h of exposure to LC30 DMT in G0 aphids, and the latter two decreased in G1 but increased in G2. In summary, sublethal DMT has intergenerational hormesis effect on cotton aphids in G1–G2 and remarkably altered their symbiotic bacterial community and abundance. These results broaden our understanding of the relationship of hormesis and symbiotic bacteria in aphids under insecticide exposure.

“…Pyrethroid degradation mechanisms have been described for Asaia , which can degrade them with pyrethroid hydrolase genes that are present in mosquito-symbiotic strains but not in non-symbiotic strains (Comandatore et al 2021). Some members of Pseudomonas are rich in hydrolases (Winsor et al 2016), such as esterases, and several can degrade different insecticides in various hosts (Cycoń, Wójcik, and Piotrowska-Seget 2009; Phillips et al 1990; Rana et al 2015; Subsanguan, Vangnai, and Siripattanakul-Ratpukdi 2020; Xia et al 2013). For example, a strain of P. aeruginosa isolated from the cockroach Blatta orientalis degrades in vitro 88.5% of endosulfan-based insecticides in under 10 days (Ozdal, Ozdal, and Algur 2016).…”

“…The high frequency of these bacteria may reflect that Pseudomonas gives mosquitoes a particular benefit. Indeed, at least some species can degrade certain insecticides [21][22][23][24][25] . However, the impact of these bacteria on insecticide resistance (or other life history traits) of mosquitoes has been largely overlooked.…”

The microbiota of mosquitoes influences many aspects of their biology, including developmental processes, mating and sexual reproduction, immune functions, and refractoriness to pathogens. Here, we considered their role in resistance against insecticides. In particular, we assessed how larval infection of a permethrin-resistant and a sensitive colony ofAnopheles gambiaeby four strains belonging to three differentPseudomonasspecies affects several life history traits and the impact of the insecticide on the mortality of adults. Our data showed that all fourPseudomonasstrains persisted in adults until death. The bacteria increased the likelihood that mosquitoes survived 24 hours after exposure to permethrin by up to two-fold. The impact of the bacteria depended on the bacterial strains and the mosquito colony: in the resistant colony, all bacteria increased survival by about 2-fold, while in the sensitive colony, only two of the four strains increased survival. The benefit with regard to insecticide resistance came with little to no impact on the other traits (i.e., larval mortality, developmental time and adult longevity). Altogether, our results highlight the importance of considering environmental microbial exposure and mosquito microbial communities in epidemiological and vector-control studies, while also suggesting a possible role forPseudomonas spp. as a symbiont inA. gambiae.
