Abstract

 

Ethanol and water extracts of five medicinal and ornamental plant species namely, Aerva lanata, Ruta chalepensis, Fagonia arabica, Malva parviflora, and Calotropis procera; were evaluated against pomegranate aphid, Aphis punicae Passerini under laboratory condition.Results indicated that the ethanol extract of R. chalepensis (whole plant) showed the highest repellency (75) and mortality (79.5) at 0.015% concentration. Followed by ethanol extract of A. lanata which elicited high repellent effect (60.68%) and moderate mortality percentage (55.54%) at 0.015% concentration. On the other side, water extracts of A. lanatacaused the highest repellency (44.88%) and mortality (61.2%) at 5% concentration. Followed by M. parviflora which induced slight repellency (36.22%) and mortality (51.5%) at 5% concentration.

 

Key words: Pomegranate aphid, Punica granatum, plant extracts, repellent, mortality.
