Natural insecticide has gone in and out of favor in the past. At first, of course, that was all there was. Then, when chemical pesticides came around, folks saw them as the wave of the future. They were all too anxious to try them. However, it may be that natural insecticide still has a place in agriculture and homes now and in the future.
Germ thurengiensis, Bt, has been developed as to be used as a natural insecticide. It is made from a bacterium that works with the bacteria in an insects gut to poison the insect. It will have to be utilized in new ways.
Farmers will have to change natural pesticide use from one to another to another. This'll help to keep the insects from becoming immune to any one natural pesticide. They'll also have to introduce natural predator insects to help with the job. It'll also help if they plant more than one crop. Meanwhile, Bt has been such a success that biogeneticists have been working to put its genetic material inside the veg rather than on them. This allows the vegetables to grow strong and insect-free. Corn has been bioengineered this way. It is called “supercorn” and it is already in supermarkets.
Is this natural insecticide? It depends upon how you look at it. Many people think that, while it uses a natural insecticide as its basis, it is highly unnatural. They would not think about eating supercorn.
One natural pesticide can have a use outside the insect-destroying business. Diguelin is a natural insecticide that has been used in South America and Africa. It has been discovered that it is effective in slowing or stopping the growth of lung cancer in humans. It is said that it'll have critical implications in the handling of particular sorts of lung cancer. Many countries in Asia, Latin America, and Africa are banding together to implement a new type of insect control. This is called Integrated Pest Management. Rather than use a natural insecticide made from a plant, a bacteria, or a mineral, IPM is based on using other insects.
These insects are natural predators of the harmful ones attacking crops. With the usage of such strategies, normal natural insecticide methods will likely be ignored in these areas, at least for awhile.
Plant terpenoids are being investigated for different uses in natural insecticide. Some of these substances can be used to repel unwanted insects and attract beneficial ones all at the same time. Molting can be stopped by use of certain plant-derived steroids.
Other plant terpenoids can be used to over-excite the nervous systems of insects. They can interrupt their mating habits and even make them sterile. The sole difficulty with the development of these plant terpenoids is that firms are aiming to make synthetic versions of them. They won't be natural insecticides.
Many folk are troubled about the environment. They want to use natural insecticide to offer protection to the safety of their food and the world around them. However the power of modern agribusiness is overtaking these people. If natural pesticide is to be a realistic solution, changes need to be made.
