Line 171:

<h3> Scale insects like to be parasitic on many kinds of fruit trees, flowers, and crops. For example, succulent plants, apricot, and apple trees attract them a lot. Besides, the honeydew they secrete can cause sooty mildew. Therefore, it is extremely important for the farmers to prevent the rampancy of scale insects. Scale insects vary in appearance, but the common thing is that they all secrete a waxy coating as their “armor”. </h3>

−

<h3> To control the effect of the scale insects on farming, nowadays farmers kill scale insect by injecting pesticides into the trunk. So ~~that~~ when the scale insect bites the trees, they would be killed. However, chemical method would result in the resistance of the insects to drugs. And there is a possibility that the whole food chain would be changed and the ecological balance would be destroyed. In order to bring convenience and safe to farmers, we decide to create a special bio-safe pesticide, making the deinsectization process faster, stronger and better.</h3>

~~Our design comes from the special characteristic of the scale insect.~~ Since its honeydew contains sucrose, we plan to use sucrose promoter, which is pretty sensitive to sucrose. After sensing the existence of sucrose, it recognizes the scale insect and starts working. Besides, since this kind of insects always damage fruit trees and succulent plants, it is important that we should keep them safe while killing those insects. Otherwise, those fruits may be stained. Thus, we design a suicide process to let bacteria suicide after wipe out those pests. After killing the insect, bacteria would kill themselves because of the suicide gene. In this way, we can ensure that our method won’t affect any plants or fruits.</h3>
