تقييم الفاعلية الإحيائية لمستخلص البتروليم إيثر والإيثانول لأوراق نبات عنب الذيب على بعوضة(Maquart)(Diptra:Culicidae) Culiseta longiareolata

The present study was carried out at the laboratory of the zoology Department, Faculty of Science, Sebha University, Libya, to evaluate the bio efficacies of petroleum ether and ethanol extracts from Artostaphylos uvaursi (Leaves) against Culiseta longiareolata mosquito by using six concentrations 12 , 6.0 , 3.0 and 1.5 ppm. The results revealed that extracts elicited significant effect on growth and development of larvae (2nd instar) represented by decrease the rate of pupation and adult emergence compared with the control. On the other hand, the results showed that the deference of temperatures between 27 and 32 Cº elicited on larvaesensitivity. Moreover, petroleum ether extracts elicited the highest effect on larvae than ethanol extracts.
