Developmental correspondence of juvenile stages across the locust, harlequin ladybird, and diamondback moth.

ABSTRACT: Insect metamorphosis is a captivating aspect of animal research. To address the controversy regarding the developmental correspondence between hemimetabolous and holometabolous insects, we utilized non-destructive micro-computed tomography (CT) imaging and RNA-seq to examine wing growth and transcriptome profiles across juvenile stages in the Locusta migratoria, Harmonia axyridis, and Plutella xylostella, with distinct metamorphic strategies. Micro-CT revealed that over 88% of wing volume increase in ladybirds and moths occurs during the prepupal-pupal transition, similar to locust nymphs. Developmental transcriptome clustering demonstrated that gene expression patterns more closely resembled those between ladybird/moth prepupae/pupae and locust nymphs, whereas holomet
