This dataset appears in the article Fraser, J.L., Abram, P.K. & Dorais, M. Supplemental LED lighting improves plant growth without impeding biological control of aphids with parasitoids in a tri-trophic greenhouse system. J Pest Sci (2023). https://doi.org/10.1007/s10340-023-01703-8Young pepper plants were grown under one of three light treatments. Each treatment had 12 hours of broad-spectrum white LED light plus sunlight as a baseline day, with the LED light serving to compensate for low levels of natural light. After this 12 hours, the plants received either an additional six hours of broad-spectrum white LED light or six hours of red and blue LED light, for a total photoperiod of 18 hours, or no additional light as a control, for a total photoperiod of 12 hours. The plants were then exposed to the green peach aphid Myzus persicae with or without its parasitoid Aphidius matricariae for another two weeks under the same light treatments, or to no insects as a control. The plants were then destructively sampled, with their dry mass and other parameters measured, and the insect densities estimated from randomly selected leaves at different heights within the plants.
