PREMISE Insect Model: Integrated Population Dynamics Model for the Ex-ante Evaluation of IPM against Insect Pest

Codling moth Cydia pomonella L. is the most serious pest of apple and pear worldwide and causes damage and decreased<br/>yields. To minimize this risk, IPM tools can be applied to reduce the use of chemicals. A cost-effective application of IPM depends<br/>on the number of insects at the time of application. Several conditions and factors influence the lifecycle and numbers of generations<br/>within a year. In order to perform ex-ante evaluations of the cost-effectiveness of IPM measures against pest insects, the generic<br/>PREMISE insect model has been developed, which integrates insect’s population dynamics, the climate and other conditions, applied<br/>measures, economics, environment and human health (residues). This paper describes these components of the PREMISE insect<br/>model, and how these components interact to assess the cost-effectiveness of IPM measures and the effects on the environment and<br/>human health. Codling moth is used as a case study for this generic mode
