Background of the Study Mahogany is a big tropical tree with a symmetrical visual aspect.
Termites are a group of insects Isoptera consisting of 2, species of which are considered pests. Termites are one of the most damaging pests in the tropics and can cause considerable problems in agriculture, forestry and housing.
There are several families and sub-families. Some have nests underground, others in wood, for example hollow trees, and some build mounds. Before control methods can be adopted a basic identification of the pest species or family is needed. This can be done by observing pest behaviour and the damage pattern on the tree or crop.
The most troublesome type of termites in agriculture are the fungus-growing termites. They feed on dead organic material such as crop residues, mulches and soil organic matter humus. However when this type of food is not available they will eat live plant material including crops such as groundnuts, millets and Mahogany seeds against termites.
Harvester termites are found in dry and semi-desert areas. They build underground nests which can be difficult to locate. They collect live green plant material and cause damage to living grasses, crops and seedlings. They will attack weak plants that are wilting or damaged.
Benefits provided by termites? Although usually considered pests, termites can also provide many benefits. Therefore before control measures are used an assessment should be made of the following benefits against the loss of termites from the ecosystem.
Aeration of the soil due to termite burrowing activities. The breakdown and release of organic matter as termites eat and digest soil. Improved soil fertility when termite mounds, which are rich in minerals, are crushed down and incorporated into the soil.
A source of minerals for cattle who lick the mounds.
A source of protein rich food for many organisms including ants, guinea fowl and other mammals including humans. In some countries, the clay of the mounds is being used to make more resistant sun dried bricks. Chemical control The generally accepted method of termite control over the years has been chemical pesticides.
However chemicals are expensive and have many harmful effects. Safety for people Artificial pesticides can quickly find their way into food chains and water courses.
This creates health hazards for humans. There is also much concern for people using chemical pesticides. The products may be misused because the instructions are not written in the language understood by the person using them. This has led to many accidents and deaths.
Safety for the environment There are a number of harmful effects that chemical pesticides can have on the environment.
Artificial pesticide can kill useful insects which eat pests. Just one spray can upset the balance between pests and the useful predators which eat them. Artificial chemicals can stay in the environment and in the bodies of animals causing problems for many years.
Pests become resistant to pesticides so more powerful chemicals are needed. Cost Using natural pest and disease control is often cheaper than applying chemical pesticides because products and materials which are already in the home and around the farm are most often used.Chapter 1Mahogany Seed as a Termiticide to Kill Termites INTRODUCTION Mahogany used in multistorey systems in the Philippines, boat and ship building and patternmaking.
Logs are used for the manufacture of veneers and for paneling.5/5(1). Mahogany is a kind of wood—the straight-grained, reddish-brown timber of three tropical hardwood species of the genus Swietenia, indigenous to the Americas and part of the pantropical chinaberry family, Meliaceae Mahogany fruit and seeds.
1. Mahogany seeds infusion is an effectual white ant slayer. 2. There is no important difference between utilizing mahogany seeds as termite slayer and commercial white ant slayers.
D. Significance of the Study The survey may give of import information about the white ant killing potency of mahogany seeds.
The degree of resistance depends on the tree species, the origin of the tree seed, the age and condition of the tree, the termite species and where the tree is growing (region/country). However as with crops, indigenous species are more resistant than exotics.
“So we tested Formosan termites on a diet of commercial lumber from 10 different species of wood—redwood, birch, spruce, southern yellow pine, red oak, Brazilian jatoba, Peruvian walnut, Honduran mahogany, teak, and Alaskan yellow cedar—to see how well the termites would do,” says Cornelius.
Mahogany is considered to be one of the most stable commercially important timbers, It is rated as moderately resistant to attack by dry-wood termites, and is susceptible to marine borer attack. Logs are vulnerable to attack by pinhole borers. Heartwood is Mahogany Genuine.
