An electrophoratic study of protein patterns in the fat bodyand haemolymphof the solitary form of the desert locust Schistocercagregaria(Foraskal).

Abstract

The polyacrylamide gel electrophorasis (PAGE) was performed on the fat bodyand haemolymphof the 5 th nymph instar as well as three different phases of adult males and females namely ; newly emerged, yellow and non yellow males (mature and non-matur), before and after oviposition females of the desert locust Schistocercagregaria. The total number of protein bands detected in the fat body and haemolymphwere 44,37respectively. The concentrationpercentage of these protein bands, the timing of band appearance and disappearance, the sex-specific proteins and the major protein bands forthe fat body and haemolymphwere detected. The protein metabolism was studied and discussed by observing and comparing the different protein patterns of the fat body tissues and the haemolymph fluid of the desert locust.
