Abstract |
: |
The concentration of total protein in the haemolymph and fat
body of the fourth instar larva of Pectinophora gossypiella Saunders increased
in diapause and in early ages of terminationofdiapause relative to
that in the active phase. In late ages of termination of diapause, a drop took
place. Thehaemolymph and fat body of the active, diapause and7 agesduring
termination of diapause of the larva were electrophoretically separated
into 15 and 12 protein bands for both tissues, respectively. The different phases
of the larva showed 2-7 protein bands whose concentration varied
greatly during induction and termination ofdiapause. Some of these bands
in both tissues examined were simple proteins, others were glycoproteins,
lipoproteins or lipoglycoproteins. Some of these bands in both tissues were
identical, while others were non-identical or specificior each tissue. During
diapause, 3 characteristic protein bands appeared in each of the
haemolymph and fat body, of which only one band was identical in both tissues.
During termination of diapause some protein bands appeared in the
haemolymph before their appearance in the fat body., or were neyer detected
in the fatbody, which suggested that some tissues, other than the fat
body, might be involved in synthesizing haemolymph protein. The
haemolymph and fat body during late ages of diapause termination regained
many of the characteristic protein pattern of the active phase. |
