Abstract

        The importance of the damage caused by aphids on Solanaceae crop in greenhouse has stimulated the present research, regarding the monitoring of the aphid dynamics on the pepper in greenhouse according to its agent of spontaneous regulation within a framework of biological control.
        This study permit to follow the fluctuations in the aphid populations, as well as those of their predator ladybug Coccinella algerica knowing that period of aphid activity (extends from March until the beginning of May) correlated with the period of activity of Coccinella algerica (which extends between the months of March until mid-June).
