These are easily available, non-toxic, biodegradable and exhibit broad-spectrum target specific activities against larval stages of mosquitoes. Method: Different potential parts of locally grown plants, seeds of nutmeg (Myristica fragrans), peel of musambi (Citrus sinensis), leaves of babuna (Matricaria chamomilla), mint (Mentha spicata) and ginger rhizome (Zingiber officinale) selected and evaluated for their larvicidal properties against Aedes (Stegomyis) albopictus. Oils were ex­tracted through steam distillation process and extracts were evaluated as per WHO 2005 guidelines for testing of insecticides against larvae of mosquitoes. Result: Among the five plant extracts, C. sinensis had the lowest LC50 (400.81ppm) while M. fragrans had the high­est LC50 value (710.30ppm) respectively after 24h of exposure. In terms of % age mortality, a series of con­centra­tions (300–800ppm) gave high % mortality in case of C. sinensis while M. fragrans gave low % age mortality. Conclusion: All the five plant species have larvicidal effects to certain extant and C. sinensis had great potential. Further small-scale field trials with the extracts of the most promising one (C. sinensis) shall be conducted to deter­mine operational feasibility.     https://jad.tums.ac.ir/index.php/jad/article/view/583 https://jad.tums.ac.ir/index.php/jad/article/download/583/336
