Cacao (Theobroma cacao L.) is a tropical crop in high global demand. Ecuador is a significant producer and exporter of cacao where, there are several fine aroma cacao cultivars (type Nacional) and CCN51 (Trinitarian origin) in which the damages caused by pests in those genetic materials have so far been little evaluated. The objective of this research was to estimate the populations of sap pests and the damage caused to the pods in some genetic materials of cacao. This research was conducted during April 2022 -March 2023 in a 2160 m 2 lot, planted in random blocks with four replicates and six families resulting from crosses: F1
