Table 2 Viability of sexually and asexually produced oothecae

From: Group-housed females promote production of asexual ootheca in American cockroaches

  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)

  1. 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
