The phenomenon was investigated here using the emerald ash borer (EAB) and its larval endoparasitoid Tetrastichus planipennisi - a compelling system where the southern range in host insect exceeds distribution of its parasitoid, coinciding with a striking endosymbiont contrast, i.e., while EAB naturally lacks Wolbachia and Rickettsia, its parasitoid maintains both endosymbionts. The study of four T. planipennisi populations (Jilin, Liaoning, Xinjiang, Beijing) revealed the Jilin population exhibited exceptional heat tolerance with 100% endosymbiont infestation. At 40°C, endosymbiont-negative (E-) wasps showed 3-hour shorter survival than endosymbiont-positive (E+) counterparts, with weaker antioxidant capacity. Crucially, rising temperatures impaired endosymbiont transmission to offspring. While beneficial, endosymbionts’ thermal sensitivity creates a trade-off that may disadvantage parasitoids versus E- host insects under climate warming. These findings advance understanding of endosymbiont-mediated climate adaptation and have important implications for biological control strategies in warming environments.
