Table 2 Comparison of reproductive and life table parameters (mean ± SE) of Hippodamia convergens fed on two aphid species

From: Life table and demographic parameters of the coccinellid predatory species, Hippodamia convergens Guérin-Méneville (Coleoptera: Coccinellidae) when fed on two aphid species

Parameters A. gossypii L. erysimi
APOP 4.286 ± 0.569a 02.60 ± 0.150b
TPOP 35.78 ± 1.094a 20.80 ± 0.415b
Oviposition period 15.90 ± 0.912b 20.10 ± 0.766a
Fecundity 251.0 ± 13.27b 319.7 ± 13.32a
Ro (offspring individual-1) 87.85 ± 19.45b 159.85 ± 25.86a
T (days) 45.10 ± 0.858a 30.49 ± 0.442b
r (days−1) 0.099 ± 0.005b 0.166 ± 0.006a
λ (days−1) 1.104 ± 0.002b 1.181 ± 0.007a
  1. SE was estimated by bootstrapping (100,000). Whereas APOP, TPOP, T, r, λ, and Ro represents adult pre-oviposition period, total pre-oviposition period, mean generation time, intrinsic rate of increase, and finite rate of increase, net reproductive rate respectively. Means sharing similar letters in each row are not significantly different at P > 0.05
