The parasitised E. cautella larvae missed one instar. No significant difference in the body weight, food consumption and fat body protein was noticed in the host during its early development stages. However, significant difference in these parameters could be noticed in the infested host during the late second and early third instars. The fat body protein content of the parasitised host was high during the second and early third instars and declined later on. The parasitoid accumulated the protein of the host gradually.
