Our model predicts that the sanitation efforts need to roughly double from the current levels to eliminate CRB from Guam. We show that, in the absence of viable virus control, the sanitation, i.e., the removal of the green waste is the most efficient way to control the population. We also identify control levels required to eliminate CRBs.
We derive the basic reproduction number determining the CRB population growth without any control measures. We calibrate and validate the model based on data count of CRBs trapped in Guam between 20. We carefully consider CRB life stages and its interplay with coconut palms as well as "the green waste", the organic matters used by CRB for breeding sites. In this paper, we present a compartmental ODE model of CRB population and control. However, a new haplotype CRB-Guam has recently escaped this control and invaded Guam, other Pacific islands, and has even established itself in the Western Hemisphere. Its expansion from Asia to the Pacific in the early 20th century has been stopped by virus control.
