Some parasitized larvae attack. the parasitoid cocoons or the pupal stage, other
attack. the larvae. In all cases the parasitized host attacks only the parasitoid produced
from its body. This phenomenon occurred in consistency with a 6% and independent
from the controlling factors (season, temperature, light or feeding). The total body
proteins were compared In parasitized and control larvae and It was found that
parasitism affected the protein pattem and this effect was characterist'c in those
larvae which attack diet's produced parasite. This phenomenon is interpret d as being
a "retaliation" of hosllarvae against the endcparasnold.
