Life table and consumption capacity of corn earworm, Helicoverpa armigera, fed asparagus, Asparagus officinalis.

Jha RK, Tuan SJ, Chi H, Tang LC - J. Insect Sci. (2014)

Bottom Line: The uncertainty associated with life table parameters was estimated by using jackknife and bootstrap techniques, and the results were compared for statistical inference.The frequency distribution of sample means obtained by the jackknife technique failed the normality test, while the bootstrap results fit the normal distribution well.By contrast, the relationship between the mean fecundity and the net reproductive rate, as estimated by the bootstrap technique, was slightly inconsistent with the relationship found by mathematical proof.

f01_01: Total number of eggs and hatched eggs laid by female Helicoverpa armigera at different ages. High quality figures are available online.

Mentions: The gap between the curves showing the age-specific total eggs laid and the age-specific eggs hatched in Figure 1 represents the difference between the number of eggs laid and the number that actually hatched. The figure also shows the changes in the age-specific hatch rate with age. This variation has been taken into consideration in the calculation of population parameters.
