Table 2 Viability of sexually and asexually produced oothecae

	Total oothecae	Hatched oothecae	Hatchability (%)^a	lengths of hatched ootheca (mm)^b	Lengths of unhatched ootheca (mm)^c	Mean no. of nymphs per ootheca (±SD)^d
Mated	30	14	46.7	8.2 ± 0.8	8.4 ± 0.6	14.3(±1.5)
Unmated	33	10	30.3	8.7 ± 0.7	8.7 ± 0.5	9.1 (±3.3)*

Oothecae produced by unmated females were collected from a colony of twenty virgin females. Oothecae were incubated at 28 °C in a 12:12 h light-dark cycle. Welch’s t-test P = 0.18 (>0.05)^a, 0.098 (>0.05)^b, 0.156 (>0.05)^c, 0.00004 (<0.0001)^d. Asterisk indicates the presence of statistical significance
