A lot of insect pests attack the garden every season.But some of them are so clearly parasitic on the beds that they can not be overlooked. These pests include Colorado beetles. Each summer resident of the Colorado potato beetle and the fight against it are associated with certain difficulties. The main reason for the hatred of the garden gardeners for this little bug is its voracity and quantity. The spread of the species occurs quickly, and it is very difficult to prevent its settlement in all the plants it prefers. This scum can be brought out of the garden only when using effective means at an early stage of infection.

Brief description of the form

The pest owes its name to the US state of Colorado, where its large-scale invasion of potato fields was recorded. The insect itself belongs to the family of leaf beetles and was first found in Mexico. There it specialized in the destruction of tobacco leaves and nightshade. Later the leaf beetle spread to the north of the mainland, where it adapted itself to eat potato tops.

The Colorado potato beetle is very noticeable on plants due to its bright colors - yellow and black stripes. It is the best known pest of potato tops.The size of the leaf beetle usually does not exceed 1 cm in length. But in width it is almost as much.

Photos of the Colorado potato beetle demonstrate its visibility against the background of dark green leaves. The rounded body covers the chitinous layer, under which the wings are hidden. The beetle flies perfectly, so its invasion of the gardens can take anyone by surprise to the owner of potato plantations.

On a note!

Beetle damage to about 80% of the green shoots of potatoes leads to the loss of at least half of the crop.

Leaf beetles have an enviable fecundity. One female is able to lay about 500 eggs at a time. Laying can be found on the back of the leaves of the potato. Red small eggs are impressive in their quantity. The larvae that hatch from them are bright red insects with a black head and limbs. They are very similar to formed beetles, but do not have a protective shell of chitin.

After 2-3 weeks the larvae descend into the ground for pupation.After another 2 weeks, an adult individual is formed from the pupa, which can remain in the ground until the next spring or crawl out and continue sabotage.

Striped insects in addition to potatoes are not averse to feast on the leaves of other garden crops:

In order to save potatoes or other garden crops from a ruthless and voracious pest, it is necessary in time to apply effective methods to combat the Colorado potato beetle.
