Abstract Protected crops like greenhouses and indoor farms using light-emitting diodes (LEDs) allow precise control of light spectrum, intensity, photoperiod for agronomic purposes. These artificial conditions also influence insects arachnids, including predators used in biological control. Despite growing interest, the effects LEDs on predator behavior efficacy remain poorly understood. In microcosm experiments, we studied locomotion predation behaviors generalist Orius insidiosus against thrips (Frankliniella occidentalis) under different spectra intensities. We tested narrowband blue, green, red spectra, 3 blue-red ratios, a spectrum combining all colors across light-intensity gradient. Predators attacked prey lighting conditions, with 70% individuals showing predatory during observations. Spectral composition significantly influenced while intensity had negligible effects. Narrowband elicited highest attack probabilities, but mixed higher proportion yielded capture rates. The showed intermediate success. complex environments cucumber plants 24-h sequences, probabilities followed similar trends to experiments. However, survival rates remained treatments. Our findings suggest that influences O. behavior, this remains effective various providing foundation strategies balance plant productivity
