The floury bedbugs are an important group of insects, in which there are many plagues worldwide recognized, for the serious affectations that they cause on cultivations of agricultural interest. Their presence and impact on Cuban agriculture is very-little known.

This work studies the presence of these species, their taxonomical identification, the relative frequency of genuses, their food preference and the distribution in the country in 30 cultivations (fruit trees, vegetables, grains, viands, sugar cane, coffee trees and cacao).

The work makes important scientific contributions from the biological and ecological point of view and constitutes a valuable support for the control and quarantine surveillance of these plagues. The results for its novelty and practical and scientific interest are a very important knowledge contribution of this group’s diversity in our agro ecosystems when updating the pseudococcide fauna present in Cuba. From these, the following genuses are reported for the first time in the country Antoninoides, Distichlicoccus, Planococcoides, Plotococcus, Paracoccus and Kiritshekella, this latest, a new report for the American continent, and the species Planococcus albi and Planococcus angelicus, new reports for sciences. This work contributes to the phytosanitary system when it reveals the geographic location and the cultivations in which the main floury bedbugs focus are present, as well as the state of these populations, which are in relative equilibrium in those undisturbed environments. The results reported have contributed to the quarantine surveillance, when permiting the detection of Paracoccus marginatus, plague recently introduced, as well as confirming that, so far, there is no presence of any exotic species, extremely dangerous mainly to our agriculture. Maconellicoccus hirsutus, whose proximity to our island has been the reason why the plague alert has been decreed, with a direct repercusion on the productive systems. It has received references from institutions and from two internationally prestigious specialists, as well as from other prestigious Cuban specialists from different institutions (Central Laboratory of Quarantine, Research Institute of Tropical Fruit Growing, National Center of Biological Security, Department of Interior Quarantine, and Ecology and Systematics Institute ), among others. The results of the work have been rewarded, presented in scientific events and published in 8 articles of scientific magazines; from these, 3 of high impact factor, 1 in a reference magazine with wide circulation and 5 in national magazines in reference database.
