BIOINSECTICIDE TEST OF CRUDE STEM BARK EXTRACTS OF SOME MELIACEOUS PLANTS AGAINST SPODOPTERA LITURA
Tukiran
In the study of screening for bioinsecticides from plants, the activity of the stem bark extracts of some Meliaceous plants growth in Indonesia, namely Aglaia odorata Lour, Aglaia odoratissima Blume, Aglaia elaeagnoidea A.Juss, Sandoricum koetjape Merr. and Xylocarpus moluccensis (Lamk.) M.Roem was investigated. Solvent residues of these stem bark of plants were obtained from different solvent extracts (hexane, chloroform and methanolic extracts). All extracts dissolved in distilled water and added tween 80 (a few drops) as emulsifying agent were separately tested at various concentration (mg/L) continuously for 1, 2 and 3 days on the third instar larvae of the armyworm, Spodoptera litura. The results indicated the presence of bioinsecticide effect which was maximum of Sandoricum koetjape. This plant extracts (hexane and methanolic extracts) gave enough sensitive effects to the third instar larvae with LC50s of 104.24 and 170.23 mg/L, respectively after 3 days of application. Meanwhile, other plant extracts showed much less sensitive and relatively insensitive after 3 days of application because their LC50 values were more than 200 and 1500 mg/L, respectively.
