Simulation of Stage-structured population growth of Myzus persicae (Suzler) (Hemiptera: Aphididade) based on age-stage, two sex life table

Abstract

The age-stage specific growth rate and fecundity of Myzus persicae obtained from an age-stage, two-sex life table analysis were used to simulate the growth of stage-structured population under two scenario of initial population structure for five temperature regimes. The first scenario was started with a newly born nymph and the second scenario was started with the youngest female. In both scenario, the population growth increased with shorter life cycle in the respective order: 17°C < 20°C < 23°C < 26°C < 29°C. In this study, computer simulation based on the agestage, two sex life table demonstrate it’s advantages for revealing stage-structured population growth. Information on the growth of a stage-structured population is critical for deciding the timing of intervention in integrated pest management approach.
