Therefore, the results of the study show that tomato was the best attractive plant of aphidiphagous in relation with the banana in the Bengamisa region by its Bottom Up effect enhanced by the Top Down effect and the confusing effect during the push-pull relationships. Finally, the biological control by conservation might be used as the best strategy control against P. nigronervosa in Bengamisa region in the Democratic Republic of the Congo.
