Today we are not talking about Warcraft, but their heads are all "Warcraft"! Food storage pests have been spurned by people since ancient times, which can be seen from their distinct and unique naming. People mostly express their behavior with words such as "silverfish" and "theft", and mostly express their colors with words such as "black" and "miscellaneous", which shows people's hatred for these "magic beasts". Today, I would like to take you to know these "Warcraft" from another perspective!
According to the taxonomic orders of boundaries, phylums, orders, families, genera, and species, most of the food storage pests belong to the animal kingdom, arthropod phylum, and insect class. Due to the limited space, today I will only briefly talk about the Coleoptera pests, and other pests will be ridiculed in the later stage.
Coleoptera pests are the main force of pests in the grain storage industry, and their families have many members, and everyone is familiar with rice elephants, corn elephants, grain beetles, bamboo beetles, chizhi grain thieves, miscellaneous grain thieves, long-horned flat valley thieves, rusty red flat valley thieves, etc. (are they "twin" brothers?!). ）。 Let's take stock of the special "skills" and "crimes" of these "Warcraft"!
Common name: corn elephant
Skill: Violent
The first thing to take stock of is the number one monster: the corn elephant Sitophilus zeamais Mostchulsky (weevil family, the first family of Coleoptera, according to statistics, more than 60,000 species have been recorded worldwide!) In the same family, there are also brothers such as rice elephants and valley elephants. The "Warcraft" of this family are distributed worldwide, endangering various grain grains and other kinds of storage materials. The main feature of the corn elephant is the elephant-like beak (like a long electric drill) that extends from the forehead and base area of the lip of the head, and the violent intrusion into the grain is almost handy. In addition, corn elephants have a more clever trick: spawning inside the grain, which will lay the eggs inside the grain, that is to say, their children are full of food and drink inside the grain, and only drill out after they have developed (a terrible skill)! Corn elephants are the main primary pests, and after the stored grain is eroded by its moth, many fragments and dust will be produced, which will cause the occurrence of late sexual pests.

Common name: Akatsuki Valley Bandit
Skills: Poisoning, suspended animation
Next, let's take stock of monster Number Two: tribolium castaneum (Herbst), the Thief of the Akatsuki Valley, and the same family of brothers such as the Miscellaneous Valley Bandit, the Longhead Valley Bandit, and the Ji Fan Thief. Most of the "magic beasts" of this family are plant-eating, often feeding on spoiled substances, seeds, grains, and medicinal herbs. The "Warcraft" species of this family vary in size and are generally elongated and slightly flattened. The Akatsuki Valley Thief is all red and copper-colored, shiny as satin, and his limbs are slender and slender, very handsome! However, the worm has odor glands (a smell that cannot be washed off on the body), which is disgusting, and everywhere it goes, it can bring a lingering musty smell to grain, especially flour and other substances, which seriously affects the appearance and taste! It is said that its secretions contain the carcinogen benzoquinone!!! In addition, the Akatsugu bandits like to haunt at night and have the ability to fake death! Due to the special body structure of the Chizhi Grain Bandit, its "lethality" to the complete grain grain is very low, so it will only appear in the middle and late stages of the development of grain storage insect pests.

Common name: valley beetle
Skills: Crush, burn
Finally, let's take stock of monster Number Three: the silkworm Rhyzopertha dominica (Fabricius) (Lycaenidae), and the same family as brothers such as Otani and Bamboo Beetle. The "warcraft" of this family not only erode grain, but also endanger wood and bamboo. They are all "high-level wanted criminals" in the storage industry, among which the Otani beetle is still a dangerous pest in China's foreign quarantine! The grain beetle has a strange shape, a body is oblong-shaped, and the mouthparts that are good at decaying are vertically downward, and they are very developed, which is simply invincible to the grain grain (sometimes a complete grain moth can be turned into a craft - the carved grain shell!). Are you an artist? ）！ The nymph also has a super reproductive ability, above 30 ° C, its reproductive ability is 4-5 times that of the corn elephant! When the damage is severe, the density of the insect population can reach 9000 heads/kg!!! The harm of grain beetles for grain storage can not be underestimated, the grain temperature rises rapidly everywhere it goes (up to 42 ° C), in addition, the powder produced by its decay grain grains will also reduce the porosity of the grain pile, resulting in ineffective ventilation, so that the custodians are bitter.

Damage Index: ★★★★★
The road is one foot high, and the devil is one foot high! The "Warcraft" have their own skills, and humans also have corresponding prevention and control techniques. Who is the "Warcraft" who created the grain storage technology? Or did the grain storage technology contribute to the evolution of the "Warcraft"? What do you think?
