EFFICACY OF WATER AND ALCOHOLIC LEAF EXTRACTS OF IBICELLA LUTEA ( STEPF.) AGAINST DIFFERENT STAGES OF CITRUS WHITEFLY ALEUROCLAVAJASMINITAKAHASHI IN IRAQ

Water (cold and hot) and alcoholic (hexan and methyl alcohol) extracts of Ibicella lutea (Satpf) leaves in different concentrations (20, 40, 60, 80 and 100%) were a evaluated against egg, nymph and adult stages of Aleuroclava jasmini Takahashi. A positive relationship existed between mortality and concentration for all insect stages. Boiled water extracts were more effective than the cold water extract. Larval mortality at 100% concentration was 35.4% for boiled water extract and 22.2 % for cold water extract. Methyl alcohol extract was more effective than hexane extract which exhibited 56.7 and 34.9% larval mortality, respectively, at 100%concentration.
