“…For example, an early study reported strong antennal responses of H. melpomene to several tropical plant-derived volatiles, such as linalool, linalool oxide I and II, oxoisophoroneoxide and phenylacetaldehyde (Andersson and Dobson, 2003). Recently, 55 compounds exclusive of androconia (specialized units where secretory glands are found) in sympatric Pieridae butterflies that would play a role in mating orientation, were reported (Nobre et al, 2021). On the other hand, some moths and butterflies can share pheromone biosynthetic pathways.…”

Genome-Wide Identification of Aldehyde Oxidase Genes in Moths and Butterflies Suggests New Insights Into Their Function as Odorant-Degrading Enzymes

Aldehyde oxidases (AOXs) are common detoxifying enzymes in several organisms. In insects, AOXs act in xenobiotic metabolism and as odorant-degrading enzymes (ODEs). These last appear as crucial enzymes in the life cycle of insects, helping to reset their olfactory system, particularly in lepidopterans, which fulfill important ecological roles (e.g., pollination or destructive life cycles). A comprehensive understanding of their olfactory system has provided opportunities to study key chemosensory proteins. However, no significant advance has been made around lepidopteran AOXs research, and even less around butterflies, a recently evolved lineage. In this study we have identified novel AOX gene families in moths and butterflies in order to understand their role as ODEs. Eighteen genomes from both moths and butterflies were used for phylogenetics, molecular evolution and sequence analyses. We identified 164 AOXs, from which 91 are new. Their phylogeny showed two main clades that are potentially related to odorant-degrading function, where both moths and butterflies have AOXs. A first ODE-related clade seems to have a non-ditrysian origin, likely related to plant volatiles. A second ODE-related clade could be more pheromone-biased. Molecular evolution analysis suggests a slight purifying selection process, though a number of sites appeared under positive selection. ODE-related AOXs have changed a phenylalanine residue by proline in the active site. Finally, this study could serve as a reference for further evolutionary and functional studies around Lepidopteran AOXs.

“…In general, higher similarities were found among males of Anteos compared to Phoebis , where only linoleic acid is shared between congenerics. 150 The most characteristic compounds in the androconial blends were benzyl salicylate ( 86 ) and hexadecanoic and hexadecenoic acids in P. marcellina , 6,10,14-trimethylpentadecan-2-ol ( 68 ) in P. argante , limonene ( 150 ) in P. marcellina , as well as ( E , E )-α-farnesene ( 147 ) in P. marcellina and A. menippe . 150…”

“…In other closely related non-mimetic Coliadini species-specific compositions of wing components were detected, suggesting use of intraspecific chemical communication. 150 The androconial blends of the co-occurring species Anteos clorinde , A. menippe , Phoebis argante , P. philea , P. marcellina , and P. statira revealed only a few dominant, autapomorphic compounds. Prevalent compounds across species are benzyl salicylate ( 86 ) in A. menippe and P. marcellina as well as a hexadecenoic acid with unknown double bond location in P. statira and P. marcellina .…”

“…These scent gland patches are oval and flaky and arranged in dense clusters of scales concentrated in the area where the fore- and the hindwings overlap, without protection to prevent evaporation except overlapping of wings when at rest. 149–151 While Dismorphiinae and Coliadinae predominantly feed on Fabaceae, Pierinae were able to specialize on Brassicaceae due to the evolution of a nitrile-specifier protein (NSP) that detoxifies prevalent glucosinolate defences and allowing the evolution of a much more diverse subfamily than its sister clades. 152…”

“…150,157 The first pheromones were described for the genus Colias . 150,158,159 In the secondary sympatric sister species Colias philodice and Colias eurytheme , male-specific secretory cells can be found on the hind wing 158,160 that have showed qualitative compositional differences. 159…”
