IN-VITRO EFFECT OF SOME SECONDARY METABOLISM PRODUCTS OF CORDIA MYXA ON SOME ASPECTS OF LIFE PERFORMANCE OF APHIS CRACCIVORA KOCH (HOMOPTERA: APHIDIDAE)

This study evaluated different concentrations of the crude phenolic and terpenoid extracts of the leaf Cordia myxa in some biological aspects of Aphis craccivora under laboratory conditions. The results showed that all plant extract concentrations were effective on adult of Aphis craccivora compared with control treatment. The mortality rates were of the adult when used 10 mg/ ml concentration of the crude phenolic and terpenoid extracts after 48 hrs of exposure 52.82 and 53.59% Compared with 6.02 and 7.61 % in control treatment respectively. Also, The crude phenolic and terpenoid extracts have affected reduced the number of birth reached 5.67 and 5.00 nymph/ Female at concentration 10 mg/ ml of the crude phenolic and terpenoid extracts Compared with 12.67 and 12.67 nymph/ Female in the control treatment respectively.
