Research on the reproduction of the species Orius laevigatus in correlation with the temperature

Entomophagous predator species such as Orius laevigatus, Orius niger, Macrolophus pygmaeus, and Amblyseius swirskii have proven highly effective in combating major pests in greenhouses and solariums, such as thrips, aphids, and phytophagous mites. In addition, these predators are highly adaptable to the microclimate conditions specific to protected areas and can use alternative food sources, which allows them to maintain their populations even during periods of low prey density. Statistical analysis confirms that temperature critically influences all biological stages of the species Orius laevigatus, with maximum performance recorded in the range of 25–28°C. Deviations from this range lead to a significant decrease in fertility, prolongation of the life cycle, and reduction in survival rate, limiting the population's potential for multiplication. At these values, the population multiplies rapidly and uniformly, which is ideal for producing colonies used in the biological control of thrips and other pests.
