EFFECT OF CALLISTEMON LANCEOLATUS (MYRTACEAE) LEAF OIL VOLATILES ON EGG HATCHABILITY OF CORCYRA CEPHALONICA AND ITS GAS CHROMATOGRAPHY-MASS SPECTROMETRY ANALYSIS

Callistemon lanceolatus (Myrtaceae) plant claimed for the management and control of rice - moth Corcyra cephalonica an insect pest of stored commodities. When freshly laid eggs were exposed to Callistemon lan ceolatus oil volatiles for 12, 24, 48, and 72 h with 20, 40, 80 or 160 µ l of oils, a marked decline in egg hatchability in this pest was seen after exposure period. The oil having insecticidal properties w h ich was extracted by Clevenger apparatus in the laboratory by hydro - distillation process, subjected to Gas chromatography - mass spectrometry technique. The presence of active ingredients of Callistemon lanceolatus oils obtained at 0.001 % yield by hydro - distillation mainly consisted of 1, 8 Cineole*62.25 %; Alpha - terpineol*8.73; D - limonene*8.40 %; Alpha Pinene*7.03 %; Alpha Phellendrene*2.85 %; Linalool*0.67 % etc. The result offers a platform for using Callistemon lanceolatus leaf oils for control and management of rice moth Corcyra cephalonica in godo wns, warehouses around the world.
