摘要：Present study was conducted to evaluate different concentrations of crude phenolic and
terpenoid extracts of the leaf Carissa macrocarpa as alternatives to chemical insecticides
in some biological aspects of Aphis fabae under in vitro condition. The results showed that
all plant extract concentrations were effective against adult of A. fabae 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 46.4
and 52.3% Compared with 9.2 and 13.8% in control treatment respectively. Also, the
crude phenolic and terpenoid extracts have affected reduced the number of birth reached
5.33 and 4.67 nymph/ Female at concentration 10 mg/ mL of the crude phenolic and
terpenoid extracts Compared with12.00 and11.67 nymph/ Female in the control treatment
respectively.
