Tamil Nadu, India*Corresponding Author:(E.mail:raambo_2006@yahoo.com)Neem Seed Kernel Extract (NSKE) and Nimbecidine has been testedagainst larval and pupal of Aedes aegypti . NSKE and Nimbicidine hasgreatly affected during life stages of Mosquito. Higher mortality of A.aegypti was evident at higher concentrations NSKE and Nimbicidine.Lethal concentration has been worked for each stages of A.aegypti.Increased mortality was noted by the treatment of Nimbicidine than theNSKE and this may be due to the specific formulation and concentration ofactive compounds in Nimbecidine. After the treatment of NSKE andNimbicidine on the larval and pupal showed significant mortality, and itmay be due to the ovicidal action of neem on Mosquito eggs. Reduction inthe developmental duration and treated Mosquito also showed deformitiessuggested that the Neem action on hormonal interference in moltingprocess of Mosquito. This paper discusses on the use of Neem basedBiopesticide for the control of Public he! alth insect pest.∗∗∗∗∗∗∗∗∗∗128
