Study the effect of some plant extracts on biological control of bed bugs Cimex lectularius (Hemiptera: Cimacidae)

This research aims to study the effect of some plant extracts on biological control of bed bugs Cimex lectularius (Hemiptera: Cimacidae) using the cold aqueous extracts of plant leaves of Eucalyptus camaldelulensis Dehnh, Eruca sativa L. and extracts plant seeds of Melia azaderach L. and Ricinus communis L., the study was conducted in Ishaqi city Salahdin governorate , the results diagnosing bed bugs male Cimex lectularius, . Adult male C. lectularius were maintained in the laboratory at 25 ± 2 ° C and 75 ± 5% relative humidity, cold aqueous extracts of plant seeds, R. communis, caused the highest percentage mortality 92.31% while cold aqueous extracts of plant seeds M. azaderach caused percentage mortality 83.14% as well as the cold aqueous extract leaves E. camaldelulensis caused percentage mortality 78.32% while the cold aqueous extract plant leaves E. sativa showed the lowest percentage mortality of 71.23%a all previous results at the highest concentration of 0.8 mg / ml after 72 hours of treatment. It is clear that the percentage mortality increase with the increase in treatment and the increase in the exposure period of the treatment.
