نویسندگان
چکیده
The butanol fraction of the leaves of Castanospermum australe Cunn. & Fraser., was tested on adult Callosobruchus analis (pulse beetle) for its insecticidal activity by impregnation method at concentration of 3, 9, 48, 240 and 354 μg / cm. The result showed that the extract is toxic to Callosobruchus analis and the LD50 was found to be 38 g/cm . KeywordsCallosobruchus analis, Castanospermum australe, Grain pest, Insecticidal activity, Saponins.

Chemical Composition and Insecticidal Activity of Myrtle (Myrtus communis L.) Essential Oil against Two Stored-Product Pests
Essential oil extracted from the leaves of Myrtle, Myrtus communis L. (Myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (Tribolium confusum and Callosobruchus maculatus). The chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (GC-MS). The major oil components were α-pinene (10.4%), α- Terpineol (10.1%), linalool (9.0%...
