Abstract
Inhibition of emergence (IE) by Novaluron (Mosquiron 100EC) and Moringa oliefera Lam.(Moringaceae) seed oil (MOSO) was assayed with first and fourth instar larvae of Aedes aegypti (Diptera: Culicidae) at ambient laboratory conditions. graded concentration ranging from 3.125- 200ig/ml including a control were tested. Four replicates of each concentration in RCBD were variously challenged with cohorts of 20 active larvae of a given instar. Mortality resulting from eclosion inhibition was recorded at 3-hourly intervals for 12 hours, and data analysed using log/probit transformation. Results indicated dosage-related mortality differences. High concentration of Novaluron gave 95% mortality of both 1st and 4th instars, while sublethal dosages resulted in 45 and 35% mortality of 1st and 4th instars, respectively. Exposure to Moringa oil resulted in 90 and 100% mortality of 1st and 4th instars, respectively, and sublethal dosages gave 30 and 25% mortality, respectively. Both toxicants showed significant (P Key Words : Novaluron, Moringa oliefera, Aedes aegypti, Toxicity, Nigeria.
