In this study, proventriculus, crop, ventriculus and ileum samples taken from 15 bees belonging to the species Bombusterrestris were used as material. UEA-I, Con-A, PNA, SBA and WGA lectins were applied to sections.
As a result of evaluation of sections to which lectin histochemistry was applied, strong UEA-I reaction was ob-served on the epithelial surface of ventriculus and ileum. Any reaction to UEA-I was not shown in the crop re-gion. Very strong reaction to SBA was detected at the epithelial surface and cytoplasm of the ventriculus and ileum. Epithelial surface of proventriculus stained with WGA very strongly. Strong or very strong reaction to PNA was observed in the epithelial surface of proventriculus and crop. Cell surface of crop did not react with ConA.
