The current study describes the chemical identification, antimicrobial, and mosquito larvicidal activities of essential oils from  Meistera caudata  and  Conamomum vietnamense , growing in Vietnam. Essential oils were extracted from the leaves and rhizomes, and characterized by the GC-FID/MS (gas chromatography-flame ionization detection/mass spectrometry) analysis. Monoterpenes (33.1–89.2 %) were the main chemical class found in these oils.  β -Pinene (30.8 %) and  α -pinene (23.8 %) were two major compounds in  M. caudata  leaf oil.  C. vietnamense  leaf and rhizome essential oils were dominated by 1,8-cineole (47.9–62.0 %) and limonene (10.3–16.2 %). With the same MIC (minimum inhibitory concentration) value of 25 μg/mL,  C. vietnamense  leaf and rhizome essential oils strongly inhibited the growth of Gram-positive bacteria  Staphylococcus aureus  ATCC 29213 and  Bacillus subtilis  ATCC 6501, respectively. For 24 and 48-h treatments,  C. vietnamense  leaf essential oil strongly controlled the growth of mosquito  Aedes aegypti  with the respective LC 50  values of 7.67 and 6.73 μg/mL, and the respective LC 90  values of 13.37 and 10.83 μg/mL. In the same manner,  C. vietnamense  rhizome essential oil also showed strong mosquito larvicidal activity against  Aedes albopictus  with the LC 50  values of 12.37 and 12.00 μg/mL, and the LC 90  values of 20.56 and 18.58 μg/mL, respectively.  C. vietnamense  essential essential oils containing a high amount of 1,8-cineole are generally better than  M. caudata  essential essential oils in both two biological assays.
