Background: Hemiptera is one of the most speciose orders of insects, and the most speciose considering Hemimetabola. Through their evolutive history, hemipterans with different feeding habits have adapted to deal with different chemical challenges. Three major gene families are involved in xenobiotic detoxification in insects: the cytochromes P450 (CYPs), carboxyl/cholinesterases (CCEs), and glutathione transferases (GSTs).

- In ecdysozoan animals, the process of moulting, which involves shedding and forming a new exoskeleton, is triggered by the hormone ecdysone and a complex signaling cascade involving neuropeptides.
- This study focuses on the insect Rhodnius prolixus to explore if the neuropeptide mechanisms for ecdysis found in Holometabola (complete metamorphosis) are also present in Hemimetabola (incomplete metamorphosis), while also examining their role in female reproduction.
- Results show that reducing specific hormones like ecdysis triggering hormone (ETH) affects nymph survival and egg hatching but doesn't change oviposition,
Orcokinin neuropeptides regulate reproduction in the fruit fly, Drosophila melanogaster.

In animals, neuropeptidergic signaling is essential for the regulation of survival and reproduction. In insects, Orcokinins are poorly studied, despite their high level of conservation among different orders. In particular, there are currently no reports on the role of Orcokinins in the experimental insect model, the fruit fly, Drosophila melanogaster.
