Swarming and pairing behaviors are significant to population dispersal of ter-mites.Tandem running is a key process in pairing behavior of dealates to find a mate.Suc-cinylation can lead to significant changes in protein structure and function,which is widely involved in metabolism and behavior regulation in many organisms.However,whether succinylation modification regulates termites'tandem running is currently unknown.In this research,we performed quantitative modified proteomics of the subterranean termite Reticulitermes chinensis Snyder before and after alate swarming.The succinylation lev-els of accessory gland protein(ACP)were significantly altered after alate swarming.We found that ACP is enriched in male accessory gland and female oocytes of termites.The acetylation and succinylation sites of ACP affected tandem running of dealates.The tran-scriptome and metabolome analyses of alates injected with ACP and its mutant proteins showed that β-alanine metabolism pathway was the major downstream pathway of ACP.Silencing the significantly differentially expressed genes in the β-alanine metabolic path-way(acyl-CoA dehydrogenase,enoyl-CoA hydratase,3-hydroxyisobutyrate dehydroge-nase,methylmalonate-semialdehyde dehydrogenase)suppressed tandem running and al-tered oviposition of paired dealates.These findings demonstrate that protein translation modification is an important regulator of tandem running behavior of termites,which im-plies that the succinylation and acetylation modification sites of ACP could be potential targets for insecticide action.Our research offers a potential approach for developing novel dispersal inhibitors against social insect pests.
