This study investigates the role of P2 neurons in post-mating behavioral changes in Drosophila melanogaster and finds they are not responsible for altered sleep and food consumption after mating.

The paper applies the Bradley-Terry model to quantify sperm competition outcomes in Drosophila melanogaster by analyzing pairwise mating trials and estimating genotype-specific competitive success.

The paper identifies genetic variation in Drosophila melanogaster that influences mating plug ejection timing, linking it to reproductive physiology and paternity outcomes.

The paper examines gene copy number variation in the Drosophila Sex Peptide seminal fluid protein network, finding correlated duplication and loss events among network members.

The paper examines the molecular evolution of octopamine receptors in Drosophila, identifying positive selection in specific regions of two receptors linked to ligand binding and signal transduction.

The paper identifies a lineage-specific gene, kj, essential for efficient sperm entry into eggs in Drosophila melanogaster, with no detectable sequence similarity to other proteins.

This study shows that the sex peptide receptor (SPR) is not required for post-mating behavioral changes in Aedes aegypti, suggesting alternative pathways mediate these responses.
