A model for hyperparasitism in malaria with environmental fluctuations

摘要

The present paper deals with the problem of enhancement of host fitness in malaria, due to the effect of hyperparasitism. The experimental evidence for such situations is reviewed. A mathematical model for host–parasite–parasitoid (tritrophic) is considered to analyze the experimental observations. The effect of environmental fluctuation in the tritrophic system is also observed and optimum values of the inaccessible parameters involved in the system are estimated for purposes of biological control.
