Nitrogen represents a primary limiting nutrient for insect growth and development, particularly for species inhabiting environments with low nitrogen availability. To cope with low nitrogen stress, insects rely on symbiotic relationships through two main strategies: biological nitrogen fixation and the recycling of nitrogenous waste products such as uric acid and urea. Both approaches convert either atmospheric nitrogen or metabolic waste into ammonia. This ammonia is subsequently integrated into the host insect through the glutamine synthetase and glutamate synthase pathways. By reviewing these biochemical reaction mechanisms, conventional study methodologies, and practical applications, the work compares the specific operational characteristics and conditions of each strategy. Additionally, it presents a conceptual model detailing how nitrogen provisioning operates across these distinct symbiotic pathways.
Insects often survive in nutrient-poor diets by partnering with beneficial microorganisms. Understanding how these symbiotic relationships convert atmospheric nitrogen and waste products into vital nutrients provides foundational knowledge about insect physiology and ecosystem survival strategies, which can inform broader biological research.
The abstract outlines applications and mechanisms of insect nitrogen acquisition, but it focuses on synthesising existing literature and proposing a theoretical model. As a foundational review, the work remains at an early stage of research, and the abstract does not indicate a specific commercialisation pathway or direct industrial use.

Nitrogen is usually a restrictive nutrient that affects the growth and development of insects, especially of those living in low nitrogen nutrient niches. In response to the low nitrogen stress, insects have gradually developed symbiont-based stress response strategies-biological nitrogen fixation and nitrogenous waste recycling-to optimize dietary nitrogen intake. Based on the above two patterns, atmospheric nitrogen or nitrogenous waste (e.g., uric acid, urea) is converted into ammonia, which in turn is incorporated into the organism via the glutamine synthetase and glutamate synthase pathways. This review summarized the reaction mechanisms, conventional research methods and the various applications of biological nitrogen fixation and nitrogenous waste recycling strategies. Further, we compared the bio-reaction characteristics and conditions of two strategies, then proposed a model for nitrogen provisioning based on different strategies.
