Relative proportions of QMP components (mean ± SD)

QMP	Virgin	Saline	Semen	Mated	Virgin versus mated
					U	P
HOB	1.98 ± 0.15	2.15 ± 0.13	2.01 ± 0.08	2.12 ± 0.10	143	0.55
9-ODA	44.54 ± 2.07	45.42 ± 0.84	45 ± 0.86	47.34 ± 1.38	159	0.92
9-HDA (+/−)	9.22 ± 1.03	7.93 ± 0.49	8.15 ± 0.29	8.03 ± 0.31	152	0.75

The relative proportions (mean ± SD) of the identified QMP compounds in the mandibular gland extracts of virgin, saline-inseminated, semen-inseminated, and naturally mated queens are shown. Statistical comparisons of the proportions of each compound between virgins and naturally mated queens were performed using a Mann–Whitney test.
