| Abstract | ||||
| I :1: ',"crop/itis rufiventris-Spodoptera /ittora/is system provides an obvious parasitoid host regulative system. The parasitized larvae were histologically studies to examine the integument and tracheal system. which were capitalized for the own benefit of the parasitoid. The thickness of the integument was reduced 8% and 32% in the thoracic and abdominal regions of the parasitized larvae. Also. the integument had curled twisted cuticle. diminished hypodermal cells with small nuclei. In the unparasitized larval integument the ecdysial space was formed while in the parasitized larvae the apolysis was blocked and host larvae died few days after parasitoid egression. The haemocoele of parasitoid larvae was decreased in diameter and was full with trachea higher in number and larger in size compared with the un parasitized larvae. | ||||
