Abstract
Maize (Zea mays L.), which is considered an important cereal everywhere, is widely cultivated in different agroecological conditions. Throughout their phenological stages, maize crops are attacked by pests and diseases, and in Ecuador these phytosanitary problems are usually counteracted with applications of pesticides. However, knowledge of beneficial entomofauna is fundamental to guide pest management programs. As part of this objective, the Coccinellidae species present in maize fields in localities (Santa Ana, Colon, and Danzarin) in Manabí province were identified. In each zone, maize plants were sampled from 2018–2019. A total of 2,654 specimens belonging to 14 taxa were collected in this study, of which Cheilomenes sexmaculata, Cycloneda sanguinea, Hippodamia convergens, Hyperaspis arida, and Psyllobora confluens were found in all the studied areas. Hyperaspis arida and Diomus apollonia are reported for the first time in Ecuador.
