Abstract:
شملت الدراسة جمع عينات من يرقات الطور الثالث والرابع لبعض انواع البعوض من الجداول المائية لمزارع القمح والشعيرفي مدينة الكوت - واسط / العراق خلال الموسم الزراعي الممتد من تشرين الثاني 2013 ولغاية نيسان 2014 ومن ثم تقييم فاعلية المستخلص المائي والكحولي لاو | The present study was established to evaluate the effectiveness of the water and alcohol extracts of Eucalyptus camaldulensis Dehnhardt Leaves on the killing of the 3rd - 4th instar larvae of some mosquito species collected from Wheat and Barley fields in AL - Kut city, Wasit province / Iraq, during the period of six months (November 2013 - May 2014). This study has been demonstrated the following results : The study showed the presence of three types in the study aquatic environment distributed on gender, type I return to the genus Aedes, a type Aedes caspius pallas and appeared during months November 2013 to February 2014. The types other two Faaudan to genus Culex two type Culex tritaeniorhynchus Giles and Culex pipines L has appeared during March and April 2014, respectively, of a monthly period extending from from November 2013 to the end of the study in April 2014. The results of the study showed the water and alcohol extract leaves the plant E. camaldulensis kill larvae in the third and fourth instar of the three types of mosquitoes effect. The following : - The alcohol extract of Eucalyptus camaldulensis leaves was more effective on the mortality of mosquito larvae than water extract after 24h following treatment. In which the (10000 ppm) at the highest concentration of both extracts (alcohol and water) showed the highest response. The mortality rate of larvae Ae.caspius of alcohol and water extracts were (100, 90) % respectively. As well as the alcoholic LC50 and LC90 that were given to same species, were calculated and the results were (8, 2700 ppm) respectively. Whilst the water extract at the same lethal concentrations findings were (2500, 9900 ppm) respectively. - The mortality rate of larvae Cx. tritaeniorhynchus of alcohol and water extracts were (73, 66) % respectively. As well as the alcoholic LC50 and LC90 that were given to same species, were calculated and the results were (6400, 12500 ppm) respectively. Whilst the water extract at the same lethal concentrations findings were (5600, 11400 ppm) respectively. - The mortality rate of larvae Cx. pipines of alcohol and water extracts were (43, 3.3) % respectively. As well as the alcoholic LC50 and LC90 that were given to same species, were calculated and the results were (16100, 22300ppm) respectively. Whilst the water extract at the same lethal concentrations findings were (zero, zero) respectively.
