The coffee production system consisting of models for coffee growth and development, coffee/coffee berry borer (CBB) dynamics, and the role of the CBB parasitoids and complementary strategies for control of CBB have been modeled and analyzed. The CBB model is based on a prior model by Gutierrez et al. (1998) with the following modifications: Refinements … Continue reading Coffee/Coffee Borer System
Models for cassava (Manihot esculenta Crantz) growth, development and yields as modified by weather, soil water and nitrogen, and natural enemies were developed. Rainfall-induced mortality and plant carbohydrate stress were the major determinants of P. manihoti population patterns prior to the introduction of exotic natural enemies. The cassava model was the basis for examining the … Continue reading Analysis of the Biological Control of Cassava Pests In SubSaharan Africa (with IITA Nigeria)
