الملخص EN

The results of the current study showed a significant effect of the compound saponine isolated and other compounds isolated.

From crude terpeniod of compounds extract of leaves and roots of the licorice plant Glycyhrriza glabra performance aspects of life for the mosquito Culex pipiens .The egg mortality rate Reached (90 %) at the treatment of a compound saponin isolated from the extract of terpeniod compound of leaves and roots of the licorice plant Glycyhrriza glabra.

While (88, 88 %) and (86, 80 %), respectively, in the two compounds No.

1 and 2 respectively for leaves and roots of plant, Compared with 4.44 % in the control treatment.

The mortality rate increased of different larval instars and pupal stage as a result of treatment of a compound saponin where 90 % and all the different larval instar and pupal stage while While ranged in leaves and roots extract between (77-90 and 80-90 %) respectively when treatment of a compound terpeniod compounds (1, 2and 3), respectively, compared with 4.44 % in the control treatment.
