Abstract BACKGROUND The potato tuber moth (PTM), Phthorimaea operculella (Zeller) is a significant pest affecting crops globally, Trichogramma chilonis (Ishii) an efficient egg parasitoid with potential for biological control against various lepidopteran pests. We found and identified the from parasitized eggs of PTM in field, but parasitism on unclear. to was evaluated based linking age‐stage two‐sex life table, functional response intraspecific mutual interference effects. RESULTS performed well eggs, females laying 53.98 lifetime, total pre‐oviposition period 9.24 days, oviposition days 3.22 high offspring survival rate (0.92), more (2.93 females/male). intrinsic increase, finite net reproductive rate, mean generation time, population doubling time were 0.328 d −1 , 1.388 36.883 offspring/individual, 10.998 2.113 respectively. Moreover, showed type II increase number eggs. inversely proportional density, upper limit daily attack estimated be 38.8, foraging interfering each other at higher densities. CONCLUSION inclusion programme feasible has promising application. © 2025 Society Chemical Industry.
