Table 2 Life table parameters of N. lugens feeding on MH63, MH63-RDV, T1C-19, T1C-19-RDV under laboratory conditionsa.

From: Cry1C rice doesn’t affect the ecological fitness of rice brown planthopper, Nilaparvata lugens either under RDV stress or not

  1. aAll life-table parameters were calculated using an SAS program written by Maia et al.41 using the jackknife method. Means ± standard error (SE) in the same rows followed by the same letters are not significantly different at P < 0.05 level.
  2. brm: the intrinsic rate of natural increase, R0: the net reproductive rate; T: the mean generation time; DT: the doubling time; λ: the finite capacity of increase.
