dc.description.abstract | Investigations on luminal proteinases of grubs of red palm weevil, Rhynchophorus ferrugineus (Olivier) [Curculionidae: Coleoptera] infesting coconut revealed the presence of two endodpeptidases viz., trypsin (BApNA-ase activity) and elastase-like chymotrypsin (SAAPLpNA-ase activity) in all stages of larval development. Highest activity of these proteinases coincided with the active feeding stage (mid-larval stage) of the insect. Results indicated that 50 g of aprotinin, 50 g of Soybean Trypsin Inhibitor (SBTI) and 1700 g of Phenyl Methyl Sulphonyl Fluoride (PMSF) inhibited trypsin activity of R. ferrugineus by 77.4%, 63.1% and 55.9%, respectively. Serine proteinase inhibitors viz., aprotinin (50 g), SBTI (50 g) and PMSF (1700 g) had a marginal reduction of elastase-like chymotrypsin activity of R. ferrugineus by 32%, 14% and 11%, respectively suggesting the serine nature of the proteinase. Aprotinin caused higher inhibition than SBTI and PMSF for both the proteinases studied. In vivo bioassay of 250 M aprotinin on coconut petiole method using early stage grubs of R. ferrugineus indicated a significant weight loss of 18.9% due to incorporation of serine proteinase inhibitor, aprotinin in a period of 120 h. Possibility of using serine proteinase inhibitor, aprotinin in the management of R. ferrugineus was suggested. Not Available | en_US |
