An Evaluation of Ants as Possible Candidates for Biological Control in Tropical Annual Agroecosystem in a situation where pest diversity is high and individual population size variable, the introduction of a specialized predator may strongly influence the population size of one pest species. Several outcomes are possible. If competitive interactions exist among the pest species, then the eliminati

Consequently, the voluminous empirical literature is eclectic, scattered, and sometimes confusing. This vast empirical base has led to only modest gains in our ability to understand extant systems.
