A multi-seasonal model of the dynamics of the African maize stalk borer

Abstract

In this paper, we build a simple, multi-seasonal mathematical model describing the dynamics of the maize stalk borer Busseola fusca (Lepidoptera: Noctuidae). We consider in this model the main harmful stages of the pests and the control methods used by farmers to reduce pest populations from one maize cropping season to another. Firstly, immature stages are controlled during the maize cropping season by applying pesticides to destroy the eggs and immature larvae present on the plant leaves. secondly, crop residues harboring the larvae are burnt or buried in the soil after the harvest. The semi-discrete model obtained is studied and the basic reproduction number of the pests is computed. The numerical simulations carried out illustrate the theoretical results and also allow us to find the minimum quantity of larvae to be destroyed at the end of each maize cropping season to eradicate pest populations in the fields.
