Parametrization of PHENOBMSBv.02 - A Model for Simulation of Developmental Instars of Halyomorpha halys

This paper proposes an extended parametrization for a simple model for the development of the invasive brown marmorated stink bug (Halyomorpha halys St & aring;l, 1855) proposed by the same authors in a previous conference. The quadratic equations for the duration of each instar under variable temperatures were obtained by regressions of datasets from a controlled temperature experiment published by other authors. Compared with the previous version of the model, in this paper was analysed the impact on the calibration of additional three different phenological data sets available in literature. The thermal efficiency for the development of each temperature record from a data logger is given by the ratio of the minimal duration of the considered instar (duration under optimal temperature to fulfil a specific stage) and the duration of the same stage at a recorded temperature. The simulated stage is considered fulfilled when the sum of the products between record duration and its thermal efficiency is equal to the minimal duration of the consideration stage. The model was tested with experimental data obtained from a life table study performed in cages under outdoor weather conditions in the Emilia Romagna region in 2015.
