Science Project Idea - How are insect pests injurious to plants?
Most of you know some of the ways in which insects are injurious to plants.You have seen rose bushes, currant bushes, or even whole trees stripped of their leaves by little worm-like animals.If you have had a garden or have been in the country in summer you have seen potato bugs, or more accurately, potato beetles.
You may have seen a little heap of sawdust at the foot of a plum, Peach or cherry tree which led you to find a grub, a worm-like animal, eating a tunnel in the wood under the bark, which if not detected would have killed the tree.You may have seen lumber which has been made useless by wormholes made by grubs, a young stage of beetles; or you have had the leaves of plants in your flower or vegetable garden eaten by grasshoppers.If you have been in an orchard which has not been well cared for, you have found that practically every apple was "wormy ".The "worm" is the young stage of a small moth which flies at night.
These are only a few of the enormous number of ways in which insects harm crops, fruit, and forests by eating them.Give other examples seen by you.
Another group of injurious insects is represented by the plant lice which you sometimes see on house plants.They do much damage to plants in general.And there are the scale insects which at various times have ruined all of the fruit trees in certain parts of the country.
The squash bug is another example of this group of insects which does harm by sucking out the juices of plants.The bedbug, of unsavory reputation, is a close relative.
It has been estimated by the Chief of the Bureau of Entomology of the United States Department of Agriculture that the damage done in one year in this country by insects is as follows: Farm crops cereals, $430,000,000; hay, $116,000,000; cotton, $141,000,000; tobacco, $17,000,000; Vegetables, $200,000,000; sugar, $8,000,000; fruits, $141,000,000 ; other crops about $55,000,000 ; making a total of over $1,100,000,000 damage done to farm crops.
In addition, forests and forest products are estimated to have suffered a damage of $100,000,000; products in storage, $100,000,000; insect borne diseases of man have caused a loss of $150,000,000; domestic animals have been damaged to the extent of $100,000,000; making a grand total of more than $1,500,000,000.
The question is, how can this great loss be lessened? Science Fair Experiment- Insect Pests As a science project, you can collect common insect pests from your garden. Find out what the bug was from the internet or insect books on plant pests. Record what pest it was and what plant it was found on. If you are lucky, you can even find the damage it caused to the plant. Take a digital camera and take pictures of the damage. Read a bit more about the pest and what damage it causes to the flower or plant you found.
