“…albopictus ( Wu et al, 2013 ; Noh et al, 2020 ), NIFoxL2 and NIFcp3C from N. lugens ( Ye et al, 2017 ) and mucin1 protein from Spodoptera exigua ( Ahmed et al, 2021 ), also resulted in chorion malformations. In R. prolixus , ultrastructural changes in the chorion have already been reported by the depletion of genes related to different pathways, such as ATG1 and ATG3 ( Bomfim and Ramos, 2020 ; Santos and Ramos, 2021 ), the E1-activating and E2-conjugating ubiquitin enzymes as well as the alpha6 subunit of the 20S proteasome ( Pereira et al, 2022 ; Faria-Reis et al, 2023 ), the UPR sensors IRE1α and PERK ( Rios et al, 2022 ), Bicaudal C, a conserved embryo development regulator ( Pascual et al, 2021 ), the acetyl-CoA carboxylase enzyme and Brummer lipase, related to lipid metabolism ( Moraes et al, 2022 ; Arêdes et al, 2024 ) and Duox, a NADPH oxidase ( Dias et al, 2013 ). These findings, when combined, indicate that chorion synthesis in insects is a susceptible process, as the silencing of genes linked to various pathways produced similar phenotypes.…”
