Abstract: | Quantitative changes in haemolymph proteins from each physiological phase of the last three larval instars of the tobacco hornworm, Manduca sexta, were studied by means of disk electrophoresis. Twelve anodical migrating protein bands were found, six of which occurred only sporadically. Total protein concentration increased from pharate third instar to late fifth instar larvae, then decreased slightly in the pharate pupal stages. Some individual bands showed cyclic patterns within each instar similar to the overall cyclic pattern of total protein, whereas other bands showed different patterns or no pattern. |
