Abstract
The phenomenon of global climate change had caused an explosion of insect pests and disease vectors . Chemical pesticides are normally used to control these pests. However, the adverse effects of these chemical pesticides, namely, high toxicity, residues in food, contamination of water and the environment resulting in human health hazard are becoming topics of growing public concern. In view of the above, there was a growing need to develop some alternative pest management strategies that are more environment-friendly. Crop vineyard industries are confronted with pest populations that cause great damage and losses. Viticulture is the art and science of growing grapes. Every detail matters and a great deal of attention has been paid to growing conditions, the differences between grape varieties, and protecting the plants from pests and diseases. The European grapevine moth (Lobesia botrana) predisposing grape berries to infection by the grey mould fungus Botrytis cinerea, or also as the Scaphoideus Titanus which is the invasive vector of the phytoplasma causing the Flavescence dorée in European vineyards. These epidemics are a serious threat to viticulture that has been increasing for more than 60 years in Europe. Thus, it is necessary to improve current control techniques and to develop new control strategies. We construct a multistage model of a physiologically structured insect population whose life history consists of fourth stages of development termed eggs, larval, pupal and moth adult (male and female). The vital rates depend on the temperature and the resources.
Numerical simulations are performed for monitoring different level of insect population present in the vineyard. We formulate optimal control problems with cost functional related to real-life costs in the wine industry.
