Abstract
Natural enemies are affected by changes in the environment, with temperature being the most influential factor. The reproductive capacity of Orius laevigatus decreases at low temperatures, while its main prey, the Western flower thrips Frankliniella occidentalis, can develop, causing a lack of control during the winter. Developing cold- resistant strains would allow early releases, thereby improving biological control in this season. Therefore, variability in the reproductive capacity of four Mediterranean wild populations and one commercial population was analyzed at 17 °C, comparing them with populations at 26 °C (control). Significant differences were observed in reproductive capacity among populations at low temperatures. Agrobío exhibited higher reproductive capacity at 26°C, while Cazorla stood out at 17°C, showing the highest reproductive capacity in both treatments compared to other wild populations. This marks the beginning of a selection process to obtain populations adapted to cold, thereby enhancing thrips biological control during the winter.
