Ladybugs: Natural Pest Control
These beloved beetles protect crops by consuming aphids and other pests, eliminating the need for chemicals in Mars greenhouses. A single ladybug devours 50-100 aphids daily, reducing crop losses by 30%. Space greenhouse trials aboard the MIR station demonstrated normal predation behavior in microgravity. Growing multiple plant species, including nectar producers, would maintain ladybug populations without additional resources, creating self-sustaining pest management systems.
