Now there are many rural children, although they grew up in the countryside, but there are many common insects in the countryside, they do not necessarily know, let alone be able to call names. Just like the common thorn moths, tianniu, digging dogs, etc. in the countryside, these are the things often seen in the countryside.
Thorn Moth and Tianniu believe that many elderly friends are more aware of it, and they have also had close contact from time to time. For digging dogs, there may be many friends who do not know much, or even only know to use the local dialect to call, the scientific name is not clear.
Digging field dogs, scientific name is called caddisflies, there are many places commonly known as earth dogs, digging dogs, lara maggots. Its diet is more heterogeneous, mainly eating wheat, corn, sorghum, cotton, vegetables, and rice on the edge of the field, which is a common pest in farmland cultivation.
The species of the scorpion can be divided into two types: the African caddiss and the North China caddisflies. African caddisflies are distributed throughout the country, but the more serious harm is still in the south of the Yangtze River, while the North China caddisflies live north of the Yangtze River.
The body characteristics of the caddisflies: the body is pale yellow, the body is densely hairy, the head is conical, and the front foot is particularly developed and can climb and dig. The African caddisflies are smaller , with 3 to 4 spines on the dorsal side of the hindpod tibia. The North China caddisflies are larger, with only one or no spines on the dorsal side of the hind foot tibia (that is, evolved).
African slugs are highly fertile, occurring once a year. The reproduction of the North China caddisflies is affected by temperature, and it takes about three years for a generation. Both species of insects, nymphs or adults, overwinter deep in the soil.
Whether it is the African scorpion or the North China caddisflies, they are all of the same genus, have a characteristic, and have a strong phototropism. Adults or nymphs, usually hiding in dry soil during the day, come out at night and eat many kinds of crops. The rhizome of the crop is bitten off, so that the rhizome tissue of the plant is destroyed, so that the plant directly withers.
In the countryside, several practical control methods have also been summarized for the prevention and control of caddisflies.
Lighting to trap adult insects: The scorpion has a strong phototropism and can use the insect trap lamp commonly used in the countryside.
The method of deep ploughing the land and using dry wheels: the scorpion has a pair of powerful forefoots, which can not only dig the soil and dig the hole, but also dig very deep. Only by ploughing the land and destroying the hiding place of the scorpion can the hiding point of the cadaver be effectively reduced.
Another characteristic of the cadaver is that it does not like water. Generally in the irrigation paddy field, it is rarely seen. But on the fields not far from the water, you can find a lot. At present, this kind of insect is planted every year by rotating water and dry rotation to destroy the living area of the caddisflies.
Use poisonous bait to booby trap: use your own homemade poisonous bait to trap, 90% of the crystal enemy insects 200 grams, add 5 to 6 pounds of water to soak water. Stir-fry 30 to 35 kilograms of cottonseed cake (bean cake, wheat bran cake, rapeseed cake) in an iron pot (do not stir-fry paste).
Fill the cottonseed cake in a container, spray the soaked insect water on the cottonseed cake, and stir well with the things. In the evening, set the release point around the field and the ground, and put 7 to 8 catties per acre. It is best to put it in the evening, and the cockroaches that have been held in the ground for a day are going to come out to find something to eat.
In fact, this kind of insect is in the southern paddy field, just say that there is, but for paddy field planting, it will only endanger the plants that rely on the edge of the field, and there is water in the middle, and the slugs will not go. Friends, do you know anything about the scorpion? (Image from the Internet)
