Table 2. Mean percentages of mated females, spermatophores per female, and oviposition from crosses of WCRL and Bt4R moth pairs

Moth pair		% mated females	No. Sperm.¹/female	Eggs
♀	♂	% mated females	No. Sperm.¹/female	Mean total No. eggs laid	Mean total No. viable eggs	Mean No. viable/ mated females
Bt4R	WCRL	81.0 a²	2.3 a	247.8 b	142.4 b	47.3 b³
WCRL	Bt4R	84.0 a	2.3 a	473.4 ab	370.4 ab	88.5 ab
Bt4R	Bt4R	96.0 a	2.2 a	425.6 ab	295.6 b	64.5 ab
WCRL	WCRL	96.0 a	3.3 a	678.2 a	568.0 a	126.7 a
F, (P)		0.60 (>0.05)	2.23 (>0.05)	4.00 (<0.05)	5.06 (<0.05)	3.26 (>0.05)

¹Sperm. = spermatophore

²Mean numbers for 5 replicates of 5 moth pairs per replicate. Means in the same column not followed by the same same letter are significantly different as determined by ANOVA and by pair wise comparisons using the Mann-Whitney Rank Sum Test, P ≤0.05, df = 3,12.

³Mean numbers of viable eggs per mated female were not shown to be signficantly different by ANOVA (F=3.26, P=0.0594), but pair-wise t-test comparisons revealed a signficant difference between ♀ Bt4R X ♂ WCRL and ♀ WCRL X ♂ WCRL (t=−3.249, P=0.012) as indicated by different letters.
