تقويم فاعلية بعض المستخلصات المائية و الكحولية لنبات قرن الغزال (Ibicella lutea Stapf.)‎ ضد الأطوار المختلفة لحشرة حفار ساق الذرة (Sesamia cretica Led.)‎

الملخص EN

Water (cold and hot) and alcoholic (hexane and methyl) extracts of Ibicella lutea (Stapf.) leaves in different concentration (20, 40, 60, 80 and 100%) were tested against the different stages of Sesamia cretica Led.

A positive relationship existed between mortality and concentration for all insect stages.

Boiled water extracts were more effective than cold water extract.

Larval mortality at 100% concentration reached 35.4% for boiled water extract versus 22.2% for cold water extract.

Methyl alcohol extract was more effective than hexane extract which led to a larval mortality of 56.7% and 34.9%, respectively, when using undiluted extract.
