Expression and Role of Vitellogenin Genes in Ovarian Development of Zeugodacus cucurbitae

open access: yesInsects, 2022
Vitellogenin (Vg) genes encode the major egg yolk protein precursor in arthropods. In this study, four Vgs were identified in Zeugodacus cucurbitae (Coquillett). Sequence analysis showed that four ZcVgs had the conserved Vg domain.

Phenotypic plasticity, trade-offs and gene expression changes accompanying dietary restriction and switches in Bactrocera dorsalis (Hendel) (Diptera: Tephritidae)

open access: yesScientific Reports, 2017
In this study, we investigated the effects of dietary restriction (DR) and variable diets on phenotypes and gene expression in oriental fruit fly, Bactrocera dorsalis (Hendel), one of the most economically important pests in the family Tephritidae around

miR-318 regulates juvenile hormone biosynthesis to control ovarian development in Bactrocera dorsalis

open access: yesCommunications Biology
Reproduction is a fundamental process in the insect life cycle, with the ovary serving as the central organ governing oogenesis and fertility. Hormonal homeostasis, particularly juvenile hormone (JH) regulation, is critical for proper ovarian development.
