Abstract AR
لدراسة تأثير مستويات ملح NaCl أو دالة الحموضة pH في بقاء يرقات بعوض Culex sp، تم جمع عينة من هذه اليرقات من بعض برك مدينة البصرة و عرضت إلى تركيز 15، 10، 5 أو ppt 20 من NaCl أو 3، 2 أو pH 4، وجد أن التركيز القاتل لنصف اليرقات (LC50) في معاملات NaCl و pH كان 6.2892 ppt و 2.98 pH على التوالي.
ماتت اليرقات في الساعات القليلة الأولى من التعرض ل 20 ppt من NaCl أو pH = 2.
تقترح نتائج هذه الدراسة أن مستويات NaCl الأعلى من 6.2892 ppt و مستويات pH الأعلى من 2.98 مؤثرة جدا في بقاء يرقات .Culex sp، و عليه فأنها يمكن أن تكون مفيدة في جهود مكافحة البعوض.
Abstract EN
-To investigate the effect of NaCl or pH levels on the survival of Culex sp.
larvae , a sample of these larvae was collected from some pools in Basrah city and exposed to 5,10,15 and 20 ppt of NaCl or 2,3 and 4 pH levels .
Lethal concentration for 50% of the exposed larvae (LC50) in NaCl and pH treatments were 6.2892 ppt and pH 2.98, respectively .All of the larvae died at the first few hours of exposure to either 20 ppt of NaCl or pH =2 .
The results of this study suggest that NaCl levels higher than 6.289 ppt and pH levels higher than 2.98 ( in Culex sp.
larvae environment ) are very effective on the larvae survival, thus these levels could be used in mosquitoes control efforts.
