This study was carried out in Sulaymaniyah governorate at two locations Qlyasan (Lat 35°33´ ; N,Long 45° 21´ ; E,750 MASAL) and Kanipanka (Lat 35° 22´; N Long 45° 43´ ; E, 550 MASAL),during the growing season of 2017- 2018 to evaluate the response of four Narbon vetch (ICARDA833, ICARDA225, ICARDA776, ICAR-DA545) varieties, and four plant Density (80Kg,100Kg,120Kg, and 140Kg) and planting date (December 5th )in Kanipanka (December 6th ) Qlyasan.The design of factorial within CRBD experiment with three replications. Means comparison was carried out by the mean of least probability difference (L.S.D) at a significant level of 5%. The results confirmed that variety No. 1(ICARDA833) and variety No.4 pro-duced the highest seed yield and some of its yield components of seeds. Using 140Kg seeds hectar-1 produced the highest seed yield and some of exhibited the highest val-ue for seed yield and some it is components and growth characters. The highest value for seed yield and most it is components produced at Kanipanka location compare to Qlyasan location.

This study aimed to evaluate the effectiveness of three concentrations (1.25, 2.5 and 5%) of the alcoholic extract of leaves and bark of eucalyptus plant (Eucalyptus camldulenis L.) against cowpea beetle Callosobruchus maculatus (Fab.) for 24 and 48 hours after treatment compared with control treatment. The result showed the ef-fectiveness of leaves and barks extracts on the mortality of insects' adults. The high-est mortality reached 60.00 % and 80.00% with the concentration 5% of bark extract after 24 and 48 hours respectively while the lowest mortality was 36.67% and 66.67% after 24 and 48 hours respectively at 1.25 % of leaves extract. The attraction rate of insect was 9.5% for 5% treatment and 3.66% at 1.25% treatment compared to the expulsion rate which was 23.5% at the concentration 5% and 21.83% at 2.5% for leaves and barks respectively.
