Description
Natural agglutinins against human, guinea pig, and rat erythrocytes (RBC) and bacteria Bacillus thuringiensis were readily detected in hemolymph of final instar larvae with resulting titers of 0-9 (log2). Titers were independent of sex and season but varied conspicuously and reproducibly with age. Moreover, response of hemagglutinins to heating varied with age being heat-labile in younger larvae, yet totally resistant to heating for 30 min at 70°C in older ones. Bacterial agglutinins were uniformly resistant at all larval ages. The study thus reveals that the amounts and physico-chemical properties of P. ricini agglutinins change with larval development. Therefore, larval age should be taken into close consideration before reporting on the occurrence and properties of agglutinins in insects. © 1988.
