Abstract AR
مستخلص 4 نباتات تم دراستها في المختبر لمعرفة تأثيرها على يرقات أخطر بعوض Culex quinquefasciatus الناقل الملاريا و داء الخيطيات، و هذا لمعرفة فعالية المبيدات الحشرية النباتية للإدماجها في برنامج المكافحة ضد يرقات Culex.
تم في المختبر معاملة الطور اليرقي بالتركيز التالية 1، 2، 3، 3، 4، و 5 ppm بالنسبة لكل من Azadirachta indica, Gymnema sylvestre, Nerium indicum Datura metel على التوالي في مختبر جامعة كانبور-الهند، حيث تمت المعاملة حسب طريقة المنظمة العالمية للصحة (WHO) 1981 أظهرت النتائج إن نسب الموت تراوحت بين (99-70 %) عند نبات Azadirachta indica، تليها Gymnema sylvestre (89-44 %) Nerium indicum , بـ 41-71 % ، Datura metel (54-19 %)، كذلك بينت النتائج أن Azadirachta indica أكثر فعالية على يرقات البعوض تليها Gymnema sylvestre ثم Nerium indicum و في الأخير Datura metel و تشير النتائج أن استخدام المبيدات الطبيعية فعال، و لهذا يمكن اتخاذها في مكان المبيدات الاصطناعية و إنقاذ بيئتنا من المخاطر الكيميائية.
Abstract EN
Aqueous extracts of four plants were tested in a laboratory for larvicidal properties against the most serious vector of filariasis and avian malaria, Culex quinquefasciatus Say (Diptera : Culicidae).
The endeavour is to further explore the use of natural insecticides in integrated vector management programmes to control larvae of Culex.
Laboratory reared larvae were exposed to 1, 2, 3, 4 and 5 ppm concentrations of the extracts of Azadirachta indica Juss., Gymnema Silvestre R.
Br., Nerium indicum Mill and Datura metel L.
respectively in Zoology research laboratory of D.
A-V Degree College, Kanpur, India.
Larvicidal assays were conducted according to standard WHO procedure 1981.
Result showed that the plant A.
indica elicited 70-99% mortality, followed by G.
Sy 44-89%, N.
indicum 41-74% and D.
metel elicited 19-54% mortality to larvae.
The extracts of A.
indica and G.
Sylvestre were found to be significantly effective in controlling Culex larvae.
The results indicate that the natural insecticides could be taken in the place of synthetic insecticides and save our environment from chemical hazards.
