A coffee agroecosystem model: II. Dynamics of coffee berry borer

This paper is the second of three on the coffee production system consisting of (1) the coffee growth and development, (2) coffee/coffee berry borer (CBB) dynamics, and (3) the role of the CBB parasitoids and complementary strategies for control of CBB. The CBB model is based on a prior model by Gutierrez et al. (1998) with the following modifications: ments of the CBB model were made and the model linked to a revised plant model for coffee (Rodrيguez et al., 2011). Several mortality factors for CBB and the effect of intraspecific competition were estimated and their importance evaluated. rameters were updated based on recent literature and field observations. fects of temperature and rainfall on the emergence of CBB adults were added. inear rate of development function was used to calculate daily degree-days to estimate accurately the effects of temperature extremes on CBB development. eld data from Colombia were used to test coffee fruiting phenology and the effect on CBB attack rates and age-structure population dynamics. eferences for the coffee berry stages were estimated for cv. Colombia.
