Table 1.

Observed mating behavior of females injected with test and control substances (Ringer's solution)

Test substances	Test		Control
	Mating	No mating	Mating	No mating
Sperm*	14	16	11	19
Cycloprolylproline†	15	15	17	13
Fatty acids‡§	1	45	20	26

Entries are number of queens with respective behavior. 

^*Pairwise posthoc test of sperm vs. control. Wald χ² = 0.61, df = 1, N = 30, P = 0.43. Univariate, χ² = 0.617, P = 0.4. 

^† Pairwise posthoc test of cycloprolylproline vs. control. Wald χ² = 0.27, df = 1, N = 30, P = 0.61. Univariate, χ² = 0.268, P = 0.6. 

^‡ A mixture of oleic, linoleic, palmitic, and stearic acids in the proportions as in natural plugs. 

^§ Pairwise posthoc test of fatty acids vs. control. Wald χ² = 11.313, df = 1, N = 46, P < 0.001. Univariate, χ² = 22.275, P < 0.0001.
