Abstract:
The research was conducted atLaboratory of Entomology-Plant
Protection Department- Collage of Agricultural Studies to determine the
effect of the plants cafour, damas and moringa against sorghum aphid
(Rhopalosiphummaidis) in February 2016.
The plants were used as aqueous extracts with concentrations (10%,
20% and 30%) to test its effect on insect mortality after 24hours and
48hours of treatment.
The study results showed that, the treated with aquoes extract of damas
at 30% concentration, obtained high mortality after 24hours of
treatment. However, after 48 hours of treatment cafure and concentration
30 % gave high mortality,while the moringa attained the lowestmortality
at concentrations 10 and 20%.
Damas could be used as aquoes extract at 30% concentration after 24
hours of treatment while cafure and moringa could be used as aqueos
extract at 30% after 48hours of concentration
