A mathematical model for the estimation of the economic tolerance limits of fruit moth infestations


, : A mathematical model for the estimation of the economic tolerance limits of fruit moth infestations. Workshop sessions: ; 401

The authors described 2 variants of a mathematical model for estimating the economic limits of Lepidoptera on fruit, with special reference to Cydia pomonella (L.) (Laspeyresia pomonella), C. Funebrana (Treitschke) (L. funebrana) and C. molesta (Busck) (Grapholita molesta). The model is based on the values of the attack frequencies assessed empirically at production and research level, and on the value of the risk assumed by evaluating these limits.
