Abstract

"SPECTROPHOTOMETRIC ANALYSIS OF THE EFFECTS OF OIL EXTRACTS OF NEFY (Azadirachta indica A. Jumm), SWEETFLAG (Acorus calamus L.) AND A NEFY-BASED INSECTICIDE, MARGOSAN-0 ON AMYLASE, NONSPECIFIC ESTERASE, AND ACETYLCHOLINESTERASE ACTIVITY IN RTCE WEEVIL, Sitophilus oryzae L." Senior Adviser: Dr. Adelina A. Barrion Junior Adviser: Cesar G. Demayo The effect of neem oil, sweetflag oil and Margosan-O on mortality effects and the amylase, o( and 6-esterase and acetylcholinesterase activity in 5. oryzae was studied. The test on toxicity revealed that Margosan-O was most effective compared to sweetflag oil and neem oil. Amylase, of and g-esterase activities, as revealed by spectrophotometry, exhibited a general trend of decreasing enzyme activity in response to increased oil concentration. On the other hand, acetylcholinesterase activity increased with plant derivative concentration.
