Chapter 1 INTRODUCTION
A. Background of the Study
Using plants to deter and keep mosquitoes away from both your home and your skin is an all-natural and safe alternative use man-made products that contain chemicals. There are a number of plants you can add to your garden and yard to naturally repel mosquitoes, One of this are the marigold plants. http://www.thriftyfun.com/tf/Pest_Control/Mosquitoes/Repelling-Mosquitoes.html
Mosquitoes. The name itself brings an itch to the skin and a frown to the face. Not only do they bite, and suck your blood, they leave an itchy welt and can even carry diseases like the Nile virus. Festive outdoor parties can be ruined by the presence of these pesky insects.Using plants like the marigold can not only help repel mosquitoes.
It’s unpleasant smell helps deter those tiny skin -nibblers and is an easy and inexpensive alternative to poisonous chemicals. Many insect repellents use a compound called Pyrethrum, which is found in marigold. This is what makes the 1
marigold plant so effective in naturally repelling these pests. Instead of using some harmful chemicals, we can use this alternative repellent to make a simple, safe and natural product to prevent those insects that can harm you.
Commonly grown as ornamental border plants, Marigolds are hardy annual plants which have a distinctive smell which mosquitoes, and some gardeners, find particularly offensive. Marigolds contain Pyrethrum, a compound used in many insect repellents. Marigolds prefer full sunlight and reasonably fertile soil. Although marigolds can be planted from seed, starter plants are inexpensive and readily available at most garden centers. Although an annual, marigold will often reseed itself in favourable conditions, or the gardener can easily collect seeds for future germination.

Besides repelling mosquitoes, marigolds repel insects which prey on crops, so you may want to plant a few marigolds in crops for added protection. Marigolds have a reputation for repelling insects, and many gardeners plant these flowers in their garden to keep insect pests off other crops.

Marigold 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.
Making your own organic and natural mosquito repellent is really quite simple, and much safer for your entire family than store bought repellents that are loaded with harmful and expensive chemicals. There are several all natural mosquito repellents on the market, but not all of them work as well as they claim or as you would like. When you are outside and enjoying everything but the mosquitoes, you don't have time to wait and see if the all natural mosquito repellent really does work.

Chapter 2 Review of Related Literature
Aromatic marigolds can serve to repel insects when planted with vegetables in need of protection from bugs and worms that dislike the flowers. Certain kinds of marigolds (Tagetes) discourage microscopically small, root-eating roundworms called nematodes and predatory insects that alight on vegetables. Marigolds also deter insects when used in homemade bug spray. But sometimes the flowers need help warding off their own attackers. French and African marigolds are often cited as the most powerful Tagetes species for repelling insects. Both contain chemical compounds called thiopenes in their seeds, roots and other plant parts that are offensive to nematodes, aphids, cabbage maggots, white flies and other pests. French marigolds (T. patula) and African marigolds (T. erecta) are also pretty additions to the garden. The flower heads of the French varieties come in single or multiple whorls and in solid or variegated shades of yellow, orange and burgundy. African (sometimes referred to as "American") species are taller than French marigolds and have larger pompom-shaped.

Marigolds can be companion planted amid vegetables to benefit them by discouraging nematodes and predatory insects. One technique involves interplanting rows of vegetables, such as tomatoes, with rows of marigolds. The Arizona Cooperative Extension and Cornell University say that preplanting an area heavily with marigolds is a powerful method for eliminating nematodes. Under the technique, a cover crop of marigolds is planted then most of the seed heads are collected at season's end to avoid an abundance of volunteer plants the following year. The plants are plowed into the soil then vegetables are planted in that location the next season. One suggestion is to split the garden in half the first year, planting marigolds on one side and nematode-resistant vegetables in the other half. Switch sides the following year, planting whatever vegetables are desired in the former marigold area. When added to an insecticidal soap spray, French marigolds discourage insects that feast on vegetable leaves. This includes the huge hornworms that bedevil tomato foliage. The Herb Gardener website offers a recipe combining marigold flowers, leaves and stems with cilantro, distilled water and dish soap. However, unlike pot marigold (Calendula officinalis) --- which, similar to Tagetes species, is a member of the aster family --- true marigolds aren't edible. They are
9
toxic to humans as well as bugs, so sprays containing their compounds should not be applied to parts of plants that people will eat.
Although marigolds are hardy flowers that are seldom bothered by pests, red spider mites can attack during hot, dry weather. Spider mites are about the size of a pinprick. They make marigold leaves turn a silvery green. The Florida Gardener website says mites are too small to see without a magnifying glass. To identify if mites are present, it suggests holding a piece of white paper under plant leaves and shaking the leaves. Any tiny red dots that move are mites. Mist plants daily in hot, dry weather to avoid the problem.
