TLDR
Quantitative evaluation of other chromatographic peaks on the analyser demonstrated that 8-day-old female flies contain twice as much free methionine as males of the same age, and the content of β-alanine amounts to about 50% higher in male than in female adults.About:

Journal ArticleDOI
A male accessory gland peptide that regulates reproductive behavior of female D. melanogaster
TL;DR: Amino acid sequencing of the purified peptide and oligonucleotide-directed cDNA cloning established that the peptide consists of 36 amino acids, and appears to be synthesized as a precursor with a hydrophobic signal sequence of 19 residues at its N-terminal end.

The sex peptide of Drosophila melanogaster: female post-mating responses analyzed by using RNA interference.
Tracey Chapman,Jenny Bangham,Giovanna Vinti,Beth Seifried,Oliver Lung,Mariana F. Wolfner,Hazel K. Smith,Linda Partridge +7 more
TL;DR: RNA interference was used to suppress SP expression, to determine whether SP is required to elicit full post-mating responses, the magnitude of responses due to other seminal fluid components, and whether SP accounts for the “sperm effect.”
Journal ArticleDOI
Fertilization and sperm competition in the nematode Caenorhabditis elegans.
TL;DR: The male sperm competition ensures male sperm utilization and thus some outcrossing in a population of predominantly self-fertilizating hermaphrodites.
Journal ArticleDOI
A few chemical words exchanged by Drosophila during courtship and mating.
TL;DR: Experimental evidence and speculation relative to chemical messages exchanged by Drosophila during courtship and mating are reviewed, and emphasis is put on female aphrodisiacs, as they clearly participate in sex and species recognition.

Mosquitoes: Female Monogamy Induced by Male Accessory Gland Substance
TL;DR: In this paper, male accessory glands were implanted in virgin females of Aedes aegypti to prevent insemination in 12 species, including Aedes, Anopheles, and Culex; interspecific transplant gave partial protection.

Amino Acid and Protein Metabolism in Insect Development
TL;DR: Physiological and biochemical studies on insect development have now provided a reasonable picture of the causal relationships of hormone action, protein synthesis, growth, and differentiation.
Journal ArticleDOI
The protein nature of the substance inducing female monogamy in Aedes aegypti
TL;DR: Gel filtration chromatography indicates matrone activity can be separated into at least two components, both macro-molecules, and at least one of the molecular components which make up active matrone is a protein.

Tyrosine-O-phosphate in Drosophila☆
TL;DR: It is shown that tyrosine- O -phosphate is a normal and prominent constituent of third instar larvae of Drosophila and accumulates during the rapid growth period following the second molt and disappears abruptly at puparium formation.
