Marigold (Tagetes erecta) plants bear yellow or orange flowers. They have a pungent odor. This is due to terthienyl production. This compound repels mosquitoes and other insects. Farmers usually grow marigold as interval plants in their vegetable garden. Marigold plant is an excellent natural mosquito repellent. Hindus use marigold extensively to worship their deities at home and in the temples. Hindu women wear marigold flowers in their heads.
The rise of the use of essential oils has expanded herbal insect repellent possibilities. At our house, where summer gardening is a daily effort, we have at various times used the essential oils of Cajeput (Melaleuca leucadendron L.), Marigold (Tagetes erecta) Citronella, Eucalyptus (Eucalyptus globulus), Geranium (Pelargonium roseum), Lavender (Lavandula angustifolia), Peppermint (Mentha x piperita), Red Cedarwood (Juniperus virginiana) and Rosemary (Rosmarinus officinalis) with great success. We use these oils either singly or in combinations diluted into hydrosol or water and sprayed liberally on our skin (taking care to avoid the eyes, of course) and clothes.
An insecticide is a pesticide used against insects. Insecticides are acetylcholinesterase (AChE) inhibitors, meaning they breakdown chemicals important in the nerves. Since insects do not have closed circulatory systems poison will travel faster to terminate the synaptic transmission.
As we know, common insecticides are harmful to the respiratory system. We aim to create an insecticide out of organic materials which will be eco-friendly and human friendly. Thus, the creation of this product will surely lead to a healthier environment. This will decrease the possible complications for respiratory diseases because according to the World Health Organization (WHO) approximately 220,000 people die each year because of pesticides.
