There are many different parasites and insect pests that attack vegetables and fruit plants in the area. These pests include the weevil. It is dangerous, attacks many plants, leading to a decrease in yield. In today's article, we will find out what a weevil looks like and how you can get rid of it.

Description

The weevil is one of the most dangerous insect pests. He actively eats almost all known species and varieties of plants on the plots. The weevil can easily devour roots, leaf blades, stems and fruits of plantings. Even not the most numerous colony of these parasites is quite capable of leaving the summer resident without a crop of raspberries or strawberries. There is also a type of insect that feeds on cereals.

The weevil is a small beetle that belongs to the Coleoptera family. The appearance of this well-known parasite depends on the stage of its development and growth. The bug larvae are very similar to miniature worms with a thick body. Most often they are colored white, cream or yellow. The shape of the larvae usually repeats the letter "C". Very small bristles can be seen along the entire length of their body. And on the head of the weevil larva there is a special dark-colored chitinous shell. As a rule, the young live and develop under the earthen layer. It is here that insects feed on plant roots. Larvae of certain subspecies of weevil can be found at the top of the earthen layer. Here they eat above-ground plant elements: stems, leaves, buds, and so on.

This is followed by another stage in the development of the weevil - the pupa. It is possible to notice the outlines of future wings, as well as the head and legs with a proboscis. Against this background, the body of the insect still has a soft structure, has a light color.

The appearance of mature beetles is very different. It all depends on the specific type of pest. Weevils can be divided into several main categories.

  • By the parameter of the length of the body. The smallest parasites rarely grow to over 1 mm. And the largest ones are 0.5 cm.
  • By the structure of the body. In nature, there are parasites that have a spherical, pear-shaped or rod-like body structure.
  • By coloring. Different weevils have different colors by nature. Thus, a chitin-type coating can show almost any color, for example, brown, black, red or yellow. You can also meet insects that have special patterns or a metallic sheen on the surface of their shell. The coloration of certain varieties looks very nice.
  • Along the length of the trunk. There are weevils that have both short and long proboscis.

In general, an adult is a coleopteran beetle with an elongated cylindrical tube-head. Thanks to the latter, pests can not only receive food, but also lay eggs in plant tissues to an impressive depth.

The beetles in question have wings. These components are very well developed, used by insects for their intended purpose - for flight. The size of the females is often more impressive than the size of the males.

In all other characters, there are no special differences between insects of different sexes.

Insect species

There are several species of weevil.Each subspecies is very dangerous for planting in the garden. We will find out what features and appearance different subspecies of elephants have.

Usually, the beet weevil exhibits an expressive black body color. However, its abdomen is gray in color, and the back is brown. Throughout the entire length of the insect's body, characteristic stripes of minimal thickness are visible. This parasite becomes especially active as soon as the first shoots of beets planted on the site hatch. Hence the name.

The beet weevil can also cause serious damage to other plants, such as cucumbers, carrots, and cabbage. The larvae of this parasite are white. Most often, they feed on plant rhizomes.

The insect subspecies under consideration is not afraid of serious frosts, since it has the ability to quickly and easily burrow into the ground layers.

Wintering of this parasite takes place in the soil layer at a depth of up to half a meter. With the onset of the spring season, the weevil comes to the surface again, and after 10 days begins laying eggs. Females lay them to a depth of 20 cm and 10 pieces in number. Already from the first days of August, mature beetles begin to fly out.

Rice

The specified subspecies of weevil is most often found in the southern regions. This parasite is considered the most dangerous for grain crops. The rice beetle is not afraid of dry conditions, it can intensively eat dried fruits and plants.

Under suitable and comfortable conditions, the female of this pest is capable of laying eggs up to 8 times a year.
