Lectins of different activities were found in the crop, midgut, and hemolymph of the insect Rhodnius prolixus. These were not specific for N-acetyl-D-mannosamine, alpha-N-acetyl-D-galactosamine, and alpha- and beta-galactose, respectively. Lectin receptors were detectable in epimastigote but not in trypomastigote forms of Trypanosoma cruzi, a protozoan parasite of the insect and of humans.
