Lantana camara Essential Oils from Vietnam: Chemical Composition, Molluscicidal, and Mosquito Larvicidal Activity.

Lantana camara is a troublesome invasive plant introduced to many tropical regions, including Southeast Asia. However, the plant does hold promise as a source of essential oils that may be explored for potential use. Fresh water snails such as Pomacea canaliculata, Gyraulus convexiusculus, and Tarebia granifera can be problematic agricultural pests as well as hosts for parasitic worms.

Essential Oil Compositions of Three Invasive Species Collected in Vietnam and Their Larvicidal Activities against , , and .

Mosquito-borne infectious diseases are a persistent problem in tropical regions of the world, including Southeast Asia. Vector control has relied principally on synthetic insecticides, but these have detrimental environmental effects and there is an increasing demand for plant-based agents to control insect pests. Invasive weedy plant species may be able to serve as readily available sources of essential oils, some of which may be useful as larvicidal agents for control of mosquito populations.

Species in Vietnam: Essential Oil Compositions and Mosquito Larvicidal Activities.

Essential oils have emerged as viable alternatives to synthetic insecticides for control of mosquito-borne pathogens. The leaf essential oils of eight species of (Lamiaceae) growing in central Vietnam have been obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. Sesquiterpene hydrocarbons dominated most of the essential oils, with the notable exception of from Ngoc Linh Nature Reserve, which had α-pinene as the major component.

Mosquito Larvicidal Activity, Antimicrobial Activity, and Chemical Compositions of Essential Oils from Four Species of Myrtaceae from Central Vietnam.

Mosquitoes are important vectors of several diseases, and control of these insects is imperative for human health. Insecticides have proven useful in controlling mosquito populations, but insecticide resistance and environmental concerns are increasing. Additionally, emerging and re-emerging microbial infections are problematic.

Species from Central Vietnam: Essential Oil Compositions and Mosquito Larvicidal Activities.

There are around 140 species in the genus , with 23 species occurring in Vietnam. The Vietnamese species have been poorly studied. In this work, the leaf essential oils of , , , , , , , and , have been obtained from plants growing in central Vietnam.

Chemical Compositions and Mosquito Larvicidal Activities of Essential Oils from Species Growing Wild in Central Vietnam.

Mosquitoes are the deadliest animals on earth and are the vectors of several neglected tropical diseases. Recently, essential oils have emerged as potential renewable, cost-effective, and environmentally benign alternatives to synthetic pesticides for control of mosquitoes. In this work, thirteen species of were collected from different areas of central Vietnam.

Mosquito Larvicidal Activity of the Essential Oils of Species Growing Wild in Vietnam.

Mosquito-borne infections are a constant problem in Vietnam, and mosquito vector control is a primary approach to control these infections. Essential oils represent environmentally friendly alternatives to synthetic pesticides for mosquito control. The essential oils of two weedy species in Vietnam, and , have been obtained by hydrodistillation and analyzed by gas chromatography⁻mass spectrometry.

Chemical composition, Aedes mosquito larvicidal activity, and repellent activity against Triatoma rubrofasciata of Severinia monophylla leaf essential oil.

Aedes aegypti and Ae. albopictus are key vectors in the spread of arboviruses such as dengue, chikungunya, yellow fever, and Zika. Triatoma rubrofasciata is an "assassin bug" whose populations and association with humans have dramatically increased and may represent a serious health concern.
