The clod stink, which is often an occasional guest in city apartments, is scientifically called a wood billboard. This is a known pest of forest and garden plants, which feeds on their juice and often leads to the death of the whole plant. The proverb "Little Bug and Smelly" originates from these insects, which became famous for their unpleasant smell.
Why bugs smell and how do they use it?
Probably, many wonder why bugs stink and why they need this very specific smell. In fact, these insects have a fairly well developed sense of smell, which allows them to perceive and classify the smells emanating from their other brethren.
Not only do bedbugs have stink, but all bugs, even waterbirds, have special glands located on the back of the cephalothorax. In these glands there is an odorous liquid, which the bug can use in case of danger. It is poisonous to other insects, can cause spasm, paralysis and even death, but it does not affect the bug itself.
Also, bedbugs use their scent to search for and attract a suitable marriage partner and scare off competitors for food or a female.
To understand how the bed bugs smell, you need to imagine the smell of a bit of rotten cognac. This smell has become a real visiting card of bed bugs (with a large cluster they smell very intensely, but the smell of several bugs is very difficult to feel).
But the most stinking bug is the woodchuck . His glands secrete a liquid that smells several times stronger than other bugs.
It is interesting…
The bed bug reveals a person by the smell of blood, which he very subtly catches. But the nest of the bugs themselves helps to find specially trained dogs, which are specially accustomed to the bug's smell. In the US, one such trained dog costs more than $ 10,000 and is a good assistant to a professional disinfector.
Who are called bedbugs?
The stink of a stink (woodchuck) has a body length of about 10-12 mm, an oval, flat shape. As can be seen in the photo, the color of the protector can vary from bright green to yellowish and brownish:
It should be noted that many relatives of this species are bright and noticeable. Like all members of the genus, the bug of the stink has a piercing-sucking oral apparatus that allows it to pierce the surface layers of plant stems and leaves and feed on their juices.
In the cold season, the woodchuck falls into a kind of anabiosis, coming out of it with the advent of spring. When a more or less warm temperature is set and sprouts start to appear from under the ground, the bug is sent to find a permanent place of residence. Most bugs like to be on the bushes of raspberries and gooseberries, often occupy larch and alder.
Immediately after the migration to plant crops, the shields mate and lay eggs. After 2 weeks, larvae appear from the eggs, which also begin to actively eat and damage the plants. The larvae are similar to miniature adults, but before their complete transformation, they expect a few lines with a complete change in the chitin cover.
The bedbug in the apartment does not bring any harm to the person and is not at all a domestic parasite. He may accidentally fly into the open window in the summer, but it will never be able to reproduce in such conditions.
In order to get rid of an insect accidentally caught in the house, it's easiest to throw it out into the street. It is worth noting that a dead or crushed bug will stink even more than a living one.
In order to prevent the penetration of the wood shield into the apartment, it is sufficient to use window mosquito nets.
The variety of bedbugs
The family of defenders consists of many representatives, each of which has its own characteristics. These stinky bedbugs are awarded by nature with an original bright color and stocky corpse, covered with a dense shell.
A characteristic feature that helps distinguish the shields from other bugs is the protrusions on the cephalothorax, which have a somewhat rectangular shape. Due to these protrusions, the bug seems even more massive and dangerous, although in fact it is harmless:
The bug usually stinks "out of fear", this is its natural protective reaction. Although bedbugs are considered bitter and not tasty, birds eat them with pleasure.
The photographs show several types of shields, which have a pronounced and strong "aroma":
- Palomene is green. This beautiful bug is notable for its green color, which turns reddish brown by autumn.
- Red-footed squadron. One of the largest representatives of the family (15 mm), its body has the color of old bronze.
- The bifurcate bidentate. One of the few carnivorous bugs, with great pleasure eats caterpillars and therefore is a useful insect.
- The berry buster. Prefers to eat those berries that are poisonous to humans (whitened, wolfberry), without refusing, however, and from the currant with raspberries.
- Northern cruciferous bug. On his back, you can see a very beautiful pattern, reminiscent of an awesome African mask.
Reproduction of the shields and their harm to agriculture
The main food of the bug of the stink is the juices of various plants, among which there are many cultivated and specially cultivated people. After the scabbard settles on the plant, it begins to rapidly die and ceases to bear fruit. Naturally, contamination of fields and vegetable gardens with such bugs brings significant losses, since affected plants either yield less crops or do not bear fruit at all.
Each bug has a small proboscis with which it extracts its food. This device helps them easily pierce the stalks, leaves or fruits of plants and drink the juice inside.
In the saliva of the bug of the stink, there is poison, which they release into the plants at the end of the meal. It is he who causes wilting. Predatory defenders in the same way pierce the skin of caterpillars and literally suck out their liquid contents.
Bugs stink of laying eggs right on those plants where they parasitize. Usually the number of eggs in the clutch does not exceed 30-40, but this number may vary slightly depending on the species. All the eggs of the shields are of an original shape, similar to vessels or chests.
Shchitniki very quickly develop resistance to various poisons, with the help of which they are trying to poison in agriculture. For this reason, the insecticide manufacturers themselves have to constantly improve the means used, trying to outrun the bedbugs for at least a year or two and not let them completely ruin the harvest.
It is interesting…
The development of genetically modified products is partly due to problems in controlling bugs: it is easier and quicker to obtain a variety of plants that are not suitable for bug food, than to breed the same variety by selection or to constantly develop new poisons.
The main sabotage of bedbug bugs occurs in gardens and orchards, they do not parasitize at home and multiply. At the end of summer, when bedbugs are looking for good conditions for wintering, they can accidentally fly into the apartment. The best (and humane) option is simply to release a bedbug - it does not bite people and can not do anything dangerous.
To fight these insects with insecticides is necessary only in the conditions of agriculture, where the wood guard is threatening the harvest of cultivated plants and its abundance is quite high.
