The main purpose of this research work was to investigate the effect of the direct seeding and conventional tillage of soybean on the incidence of plagues and natural enemies. The study was carried out on the farm “Día y Noche” of the Basic Unit of Cooperative Production “28 de Octubre” (UBPC, for its Spanish acronym), and in the Laboratories of the Agricultural Research Center of Central University of Las Villas. Field experiments were conducted on an Inceptisol, since November 2013 to May 2014. The soybean cultivar Incasoy – 27 was used. The insects in relation to the development stages of the plant were identified and quantified. In both systems 10 species of phytophagous insects and one of entomophagous insects were quantified; Hedylepta indicata L. stands out with more presence in the direct seeding, while Diabrotica balteata LeConte and the species belong to the family Pentatomidae caused most damage to the plants in conventional tillage.
