Diseases that are vectored by mosquitoes, such as malaria and dengue, have important associated
economic impacts in countries with tropical and subtropical climates because they have
significant detrimental impacts on the workforce. Decreasing susceptibility and resistance have been
ever-present threats since the introduction of synthetic insecticides. Compounding this is our inability
to identify or create new major classes of pesticides since the discovery of pyrethroids. Plants rich in
bioactive biodegradable phytochemicals of less toxicity to the environment are thought to provide the
solution. This review specifically examines available research on the mosquitocidal activity of eighty-one species of plant
seeds. The essential oils from seeds were found to demonstrate a range of larvicidal, adulticidal, growth regulating,
ovicidal, oviposition deterrent, and repellent activities. The lethal concentrations and toxicity of more highly active botanicals
are comparable to those of organophosphates, which makes them potential candidates for future laboratory investigation
and field evaluation.
Keywords: Bioinsecticide, botanical derivatives, seeds, mosquitoes, mosquitocidal activity.
