The efficiency of natural enemies, especially the exotic parasitoid Epidinocarsis lopezi (De Santis) and the indigenous predator Exochomus troberti Mulsant, in reducing populations of the cassava mealybug (CM), Phenacoccus manihoti Mat.‐Ferr., was studied through exclusion experiments. In the phy...
