OCCURRENCE OF PSEUDOMONAS AERUGINOSA (SCHROETER) MIGULA IN HAEMOLYMPH OF GRASSHOPPERS AFTER INFECTION BY FEEDING

Abstract

When adults of the grasshopper Melanophis bivillalus (Say) were fed large doses of Pseudomonas aeruginosa (Schroeter) Migula, the haemolymph remained sterile for various lengths of time. Most of the infected grasshoppers first carried small numbers of P. aeruginosa in the haemolymph and all but one died in 1 to 3 days after its first appearance in the haemolymph.
