Insects are important organisms in multiple human activities, representing about 80% of the animal kingdom. The agricultural sector, one of the highest priorities in terms of sustainable development, contributes to the production of food, raw materials, among others. In the western region of Panama, strategic crops are developed for food and nutrition security (FNS), agroindustry and agroexports; which on the one hand can be affected by pests, but on the other can benefit from the presence and activity of natural enemies (predators and parasitoids), pollinators, to mention a few. This document is a systematic review of the entomological contributions developed in recent years in the western region of the country, especially in strategic crops. To do this, three main topics were defined: fruit trees, living fences and ornamental plants; ii) Vegetables; iii) Agro-industrial crops like sugar cane. Among the most notable contributions are the updating and expansion of the known distribution of different insect species, the description of a weevil species new to science, the application of entomopathogenic microorganisms for pest control, the identification of plants associated with beneficial organisms, among others. In summary, entomology continues to provide contributions for the strategic development in the country; given that this type of research provides a basis for implementing alternatives that are practical and sustainable. It is necessary to continue raising awareness about the importance of insects and the roles they play in productive agroecosystems.
