Ex-ante Economic Analysis of Biological Control of Coconut Mite in Benin

ABSTRACT The coconut mite, Aceria guerreronis Keifer, has been identified

as one of the pests that pose a threat to the coconut industry in

Benin using a standard economic surplus model. The study

presents the simulation results of the economic benefits of the

biological control of coconut mites in Benin. In the least optimistic

scenario, the economy would derive an overall net-gain of

US$155,213.40. Considered at a discount rate of 12% for the

period 2008-2027, net present value was about US$207,721,

while the internal rates of return or break-even discount rates

are high at 13.21%. It is therefore recommended that contemporaneous

with the release of natural predators of the coconut

mite, plans should be underway for improving research and

extension services to coconut farmers in Benin.
