dc.description.abstractThe common approach to ward-off epidemics of this dengue viruses is depends on chemical insecticides. However, due to the public concerned and environmental protection strategies, more researches on biological control of the vector are actively proposed. The use of bio-potency natural products from plant derivatives, which are Ipomoea cairica (coastal morning glory) and entomopathogenic fungi (Metarhizium anisopliae) were evaluated in this study towards the larvae stage of Aedes aegypti and Aedes albopictus mosquitoes. Ipomoea cairica leaves plant extracts were segregated for the extraction preparation using a Soxhlet apparatus with acetone as the solvent. The results from bioassay demonstrate that I. cairica leaves extract treatment were highly effective to induce larvicidal mortality of Ae. albopictus and Ae. aegypti within 24 and 48 hours post-treatment. Results from factorial analysis of variance (ANOVA) also indicated there were significant differences in larvicidal activity between species and strains used (P<0.05). Based on probit analysis, it is interesting to notify that the sequence of effectiveness larvicidal activity of I. cairica acethonilic leaves extract are in the manner; Ae. albopictus field strain > Ae. aegypti laboratory strain > Ae. aegypti field strain > Ae. albopictus laboratory strain. Eventhough, I. cairica extracts showed high efficiency against Ae. albopictus compared to Ae. aegypti, however, it is contended for us to identify I. cairica leaves extract still effective towards Aedes larvae.en_US
