Physiological profiles associated with ceasing growth of unfertilized eggs produced by unmated queens in the subterranean termite Reticulitermes chinensis.

Li G, Liu L, Sun P, Wu Y, Lei C, Chen X, Huang Q - Biol Open (2016)

Bottom Line: In Reticulitermes chinensis, a close relative of R. speratus with asexual queen succession, unfertilized eggs can be produced but do not hatch as larvae.Fertilized eggs had significantly lower quantities of five amino acids (Cys, Met, Ile, Leu and Tyr), Ca, protein and cholesterol during development.Overall, changes in these physiological indices may substantially affect ovarian and embryonic growth and inhibit development of unfertilized eggs in R. chinensis.

Differences in the content of four nutrients between unfertilized eggs/unmated queens and fertilized eggs/mated queens. Data represented as mean±s.e.m. Asterisks denote significant differences by paired t-test; n=4; n.s. not significant; *P<0.05; **P<0.01.

BIO017319F5: Differences in the content of four nutrients between unfertilized eggs/unmated queens and fertilized eggs/mated queens. Data represented as mean±s.e.m. Asterisks denote significant differences by paired t-test; n=4; n.s. not significant; *P<0.05; **P<0.01.

Mentions: The levels of proteins and cholesterol in unfertilized eggs from FF colonies were significantly higher than in fertilized eggs from FM colonies (Fig. 5A, protein: t=4.038, d.f.=4, P=0.016; Fig. 5B, cholesterol: t=3.500, d.f.=4, P=0.025), but the glucose level of unfertilized eggs was significantly lower than in fertilized eggs (Fig. 5C; t=−6.124, d.f.=4, P=0.004). There were no significant differences in the triglyceride level between unfertilized and fertilized eggs, but the triglyceride level of unmated queens was significantly lower than in mated queens (Fig. 5D; t=−2.906, d.f.=4, P=0.044).Fig. 5.
