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 decreasedyields. To minimize this risk, IPM tools can be applied to reduce the use of chemicals. A cost-effective application of IPM dependson the number of insects at the time of application. Several conditions and factors influence the lifecycle and numbers of generationswithin a year. In order to perform ex-ante evaluations of the cost-effectiveness of IPM measures against pest insects, the genericPREMISE insect model has been developed, which integrates insect’s population dynamics, the climate and other conditions, appliedmeasures, economics, environment and human health (residues). This paper describes these components of the PREMISE insectmodel, and how these components interact to assess the cost-effectiveness of IPM measures and the effects on the environment andhuman health. Codling moth is used as a case study for this generic mode
