US, WASHINGTON (ORDO NEWS) — No matter what continent grows agricultural crops, farmers all over the world are faced with the problem of harmful insects that destroy crops.
The presence of such insects forces farmers and scientists to develop new and new ways to fight them and preserve the crop. What complicates the situation even more is the fact that those insects or diseases that affect crops in one region can be completely harmless in another, and therefore those protective measures that are taken in one region are useless in another.
That is why farmers spend a lot of time and effort to determine which protective measures are suitable for the crop in certain conditions and a specific climate.
Despite all efforts, insects inflict irreparable damage in one or another region from year to year, which leads to the death of the crop.
Below we will talk about harmful insects that are dangerous to the crop.
Western corn beetle
One of the main pests of corn in the United States, where annual losses and expenditures to combat it amount to about $ 1 billion. Beetles eat pollen, corn columns, grains of milk-wax ripeness, and the larvae feed on the roots of the plant. Adult beetles feed on pollen from many plant species. The U.S. Department of Agriculture estimates that a Western corn beetle causes a loss of $ 1 billion annually, including $ 800 million in crop loss and $ 200 million in corn processing costs.
Farmers use various methods to control the beetle population.
Whitefly is a real horror for farmers, as it harms plants throughout all stages of life. It is difficult to deal with a whitefly, since the destruction of an insect requires complex control and prevention measures in all available ways: biological, chemical, mechanical, and folk.
It is estimated that whitefly damage alone in the United States reaches about $ 2 billion annually.
It is noted that whiteflies quickly develop immunity to various pesticides, which significantly complicates the fight against these insects.
Ashennous Emerald Narrow-bodied Goldilocks
These insects develop on ash trees, as well as on some types of elms and nuts. Ashenic emerald narrow-bodied goldfish belongs to the group of aggressive stem pests that are able to settle on living, usually weakened trees, which inevitably leads to their death.
In the trees inhabited by gilding, drying begins from the upper part of the crown and gradually spreads lower.
This beetle lays eggs on old, sick or felled pines and very rarely on spruce trees. Its larvae make long passages in the thickness of the bark. The June generation of beetles attacks young vertex shoots of pine trees and eats their core, as a result of which these shoots, after the beetles left them, often break off by the wind.
To destroy the beetles found in many places in Russia and Germany, spread hunting trees or arrange decoy trees, chopping off the tops of some pines, and the beetle attacks particularly flexible trees, which are then destroyed.
Corn leaf scoop
Caterpillars of this insect are a pest of common agricultural plants, in particular corn.
Modern pesticides and genetically modified plant species are used to control pests in the Americas.
As is the case with other pests, considerable funds are spent on the fight against this insect, while the corn leaf scoop continues to cause great harm to the corn crop.
This insect, falling into favorable conditions for life, begins to multiply in mass. And since it does not have natural enemies in the new habitat, its spread becomes a real disaster, causing significant damage to farms that produce tomatoes.
In 2006, the insect was brought to Spain, where rapidly breeding colonies of South American moths literally began to destroy entire tomato plantations, as a result of which the insect began to pose an economic threat to the country as a whole. Then the insect spread throughout Europe, and is currently a threat to the agricultural industry.
Locusts are found almost everywhere, with the exception of the coldest areas. History knows many examples of how locusts destroyed crops, which even led to starvation. Currently, vast areas of crops across the Earth suffer from locust invasions, especially in Africa. Ethiopian authorities have reported that locusts destroyed 500 acres of farmland.
In addition to Ethiopia, countries such as Somalia, Kenya, Djibouti, Eritrea, Tanzania, Sudan, South Sudan and Uganda suffered. In these countries, a full-scale food crisis may unfold, as confirmed by the Food and Agriculture Organization of the United Nations.
