| detection of insect immunity substances (lectins) in the midgut extracts from larvae and adult red palm weevil rhynchophorus ferrugineus (olivier) in al-ahsa, saudi arabia. | the hemagglutination activities of midgut (mg) fractions of red palm weevil, rhynchophorus ferrugineus against mammalian erythrocytes (rbc) from man (abo), rabbit, horse and sheep were studied. the highest titers were seen with rabbit rbc (p < 0.05) followed by human group b, human group o, horse, human group a, human group ab and sheep, respectively. insect age and nutritional status significantly influenced the agglutinating activities. some of the unfed insects were having low activities (p > ... | 2010 | 20464944 |
