Insecticides Pests Science Project Idea

Science Project Idea-How injurious insects may be destroyed?

What do you think would be the best method of destroying insects that eat the leaves of plants?The usual way is to spray the tree with a poisonous mixture.Paris green mixed with lime and water is frequently used.Senate of lead is less apt to injure the leaves and is replacing Paris green to a great extent.To prevent apples from becoming wormy, it is necessary to spray the tree just as the petals fall from the blossom and while the calyx is still open.This is because the moth lays eggs in the blossom and the poison must get into the cup formed by the calyx before the little larva, or "worm," has a chance to eat its way into the fruit.Of course insects that live by sucking juices from plants are not affected by poisonous sprays.They are usually killed by being suffocated in some way.Dry insect powder may be sprayed over the plant by bellows.This clogs up the breathing holes along the body of the insect.A spray made of kerosene, soap, and water, another made of whale oil soap, and still another made by pouring hot water over tobacco stems, have been found to be effective in killing these sucking insects.In greenhouses and cold frames which can be tightly closed, tobacco smoke is valuable for killing plant lice.

Science Fair Project Idea

Think of the best method of being able to destroy insects that eat leaves and present it in a manner where first you introduce the insect (features, environment it lives in, DIAGRAMS!) and then propose a method on how it can be destroyed and the effects that its destruction will have on its environment.
