Total comparison of parameters including: net reproductive rate
, intrinsic rate of increase, generation time and doubling time showed that the cowpea was more sensitive host in comparison with others.
Three different schedules of the distribution of mortality within a year have different consequences for the annual contribution to net reproductive rate
For a given kernel, the minimum speed c of a rightward moving wave of invasion will depend upon the net reproductive rate
3014 progeny per day) and the net reproductive rate
(140 to 187 female eggs per female) (Chien et al.
Soybean aphids in the K-deficient treatment exhibited significantly greater intrinsic rate of increase, finite rate of increase and net reproductive rate
relative to aphids feeding on non-deficient leaves.
