Abstract

Plodia interpunctella (Hübner,1825) (Lepidoptera:Pyralidae) is a pest insect known to cause damage to stored products, including seeds, grains and dried fruit, compromising their quality and commercial value. This study investigated the vertical distribution of P. interpunctella in stored pink pepper (Schinus terebinthifolia) seeds collected at the Aroeira Association in Piaçabuçu, Alagoas. The bag was subdivided into 5 cm layers (0-5 cm, 5-10 cm, 10-15 cm and 15-20 cm), totaling four layers. A total of 103 larvae were counted, as well as pupae, adults and a cluster of eggs, with a higher concentration of larvae in the lower layer (15-20 cm). These results highlight the need for effective integrated management practices to prevent infestations and preserve seed quality. The study contributes to knowledge of the interaction between P. interpunctella and pink pepper seeds, promoting more effective control strategies to avoid financial losses and exclusion of the product by consumers.
