| Abstract |
Laboratory study was conducted on Trichogrammatoidea bactrae Nagaraja, the specific parasitoid of Pectínophora gossypiella (Saunders) eggs. This study aimed to identify whether the wasp quality deteriorated after rearing for several generations on the factitious host Sitotroga cerealella Olive eggs and whether the rearing of parasitoids on this factitious host for several generations would influence the acceptance of the target host (P. gossypiella eggs). For this purpose, four different rearing lines were established. These lines were started with parasitoids from two laboratory stock cultures reared separately for several generations on P. gossypiella and Sitotroga cerealella eggs, respectively. Comparing with laboratory stock culture, there is no deterioration in females' fecundity by continuous rearing on the two hosts. On the other hand, the continuous rearing of the parasitoid on the factitious host S. cerealella eggs did not loss the parasitoid acceptance to the target host, P. gossypiella eggs. Meanwhile, enhancement in females' quality occurred by adding pink bollworm eggs to S. cerealella culture every six generations.
