This study aimed to evaluate the suitability of using the factitious host Corcyra cephalonica eggs for domesticating the natural enemy Telenomus remus and its effect on domestication. The para-sitic effects of T. remus on different generations of domesticated C. cephalonica eggs were analyzed. Biological parameters including developmental period,female longevity,and parasitism efficacy were compared between the domesticated F30 generation of C. cephalonica eggs and Spodoptera litura eggs. The results showed that the parasitism rates for domesticated F1,F10,and F30 generations were 1.94％,16.14％,and 85.00％,respectively,with emergence rates of 4.76％,30.28％ and 85.72％ . Parasitism and emergence rates of T. remus reared on C. cephalonica eggs were significantly increased. The develop-mental duration and female longevity of the domesticated F30 generation of C. cephalonica eggs were 12.67 d and 6.92 d,respectively. Although the developmental duration was significantly extended com-pared to the domesticated S. litura strain,female longevity did not significantly differ. The parasitism and emergence rates of the domesticated F30 generation of C. cephalonica eggs were 98.63％ and 84.33％,respectively,and for S. litura eggs were 99.04％ and 80.81％,respectively,with no significant difference observed. These results indicate that C. cephalonica eggs are excellent factitious hosts for propagating T. remus,demonstrating significant potential for commercial application and biological con-trol of Noctuidae pests.
