How to control Tianniu larvae, a special medicine for green accounts - how to control celestial cattle larvae 0202 How to control Tianniu larvae How to prevent and treat celestial cattle larvae? How can I control celestial cattle? The celestial cow is a herbivorous insect and the main pest in forestry production, crop cultivation and construction timber. There are many species of celestial cattle. There are 2,200 known species in the world, and there are about 2,200 species in China. Distributed in guangtian cattle, it is a herbivorous insect and a major pest in forestry production, crop cultivation, and construction timber. There are many varieties of celestial cattle. There are 2,200 known species in the world, and there are about 2,200 species in China. They are widely distributed and harmful. So how can celestial cattle larvae be prevented and treated? How can I control celestial cattle? What do celestial cows eat? Celestial cows are herbivorous insects. They are known to have different habits of eating pollen, tender bark, twigs, leaves, roots, tree juice, fruits, fungi, etc., and flower cows often eat pollen, and gouge celestial cows often eat tender bark, twigs and leaves. Tianniu is the main pest in forestry production, crop cultivation and construction timber. It harms most pine, cypress, willow, elm, walnuts, citrus, apples, peaches and tea, etc., some cotton, wheat, corn, sorghum, sugar cane and hemp, etc., and a small number of timber, buildings, houses and furniture. Using natural enemy control and physical control of celestial cattle insecticides to control and control celestial cattle that have downward cavities on larvae and have excretion holes, can be sprayed into the wormhole with a special agent for green tent celestial cattle to control older larvae. Control adults. According to the habit of adults to supplement nutrition, spray 5001,000 times the liquid of commonly used pesticides during adulthood. Mulberry cows feed on mulberry plants to supplement nutrition. They can plant a small number of mulberry trees or make trees as bait trees in the forest, and spray medicine on the bait trees during the adult development period; many celestial cattle adults like to eat dense source plants for nutritional supplementation, and can spray honey plants during the adult stage. Timber harvested in summer and autumn should be stacked and sprayed in a timely manner to prevent and treat it. Forestry prevention and control 1. Select tree species suitable for local climate, soil and other conditions for afforestation. 2. Avoid the formation of large-scale plantations by simple tree species. The mixing method can be block or strip. 3. Select resistant tree species and resistant strains, such as poplar, camellia, paulownia, locust, etc., to prevent the spread of bare-shouldered celestial cows and macular celestial cows. 4. Regularly remove the sprouting foliage on the trunk to keep the trunk smooth. Improve ventilation and light transmission in woodlands to prevent adults from laying eggs. Change the incubation conditions of eggs and increase the natural mortality rate of larvae that first hatch. 5. Adjust the harvesting period, and cultivate small-diameter materials in the short term in areas where the main Tianniu is seriously harmful. Prior to the rampant outbreak of celestial cattle, not only was wood processed and utilized in a timely manner, but also reduced the growth rate of insect mouths. 6. Do two and three clean cuts, and promptly remove pest and pest wood, dead wood, pressed wood, weakened wood, wind folding wood and wind fallen wood, etc., in order to adjust the density of forest division and enhance the tree trend. 7. For young poplar wedge celestial cows, black-eyed celestial cows, etc., seedlings and branches with bugs should be combined with winter pruning to remove the larvae and eliminate the larvae in them to reduce the wintering bug mouth. 8. Plant stinky camellia and neem as avoidance isolation zones in forest areas where mulberry tianniu occurs, and pond cedar and metasequoia are planted as blocking isolation zones in forest areas where clouds and white striped celestial cattle occur. 9. Improve the monitoring organization for dangerous Tianniu, and implement the responsibility system and scientific monitoring methods. Regularly inspect, issue forecasts, and guide prevention and control work. What are the hazards of celestial cattle? The larvae of celestial cows eat trunks and branches, affect the growth and development of trees, weaken the tree, cause germs to invade, and are easily broken by wind. When the damage is severe, the whole plant dies, the wood is spoiled, and the craft value is lost. During the larval stage, celestial cows corrode trunks, branches and roots. Some of them harm herbs. Larvae live in stems or roots, such as chrysanthemum cows, melon vine celestial cows, etc. Individual species, such as cotton capsule celestial cattle, are harmful to cotton gibbons. There are also a few species where larvae do not live in plant tissue, but eat roots in the soil, such as large teeth and curved teeth saw celestial cows, grass celestial cows, etc. What kinds of celestial cows are there? 1. Tiger Tianniu: Tiger Tianniu is a pest. It is an insect of the genus Coleoptera Gentian spine tiger. It mainly includes Dawn Tiger Tianniu, Mulberry Tiger Tianniu, Grape Tiger, Poplar spine Tiger Tianniu, etc. Adults appear in summer and live in mountainous areas at mid-altitude. 2. Xingtian cow: Xingtian cow is a type of celestial cow unique to Japan, China and South Korea. It can harm various trees such as poplar, willow, elm, French sycamore, jujube, panli, etc., and is also the main pest of violet, hanging suzuki, and citrus. 3. Saw celestial cattle: Saw celestial cattle is an insect of the genus Gentian family. The main host plants are conifers, pine, cedar, cypress, quercus, beech, etc., distributed in Northeast China, Inner Mongolia, Hebei, Zhejiang, Sichuan, Taiwan and other places. 4. Skinny celestial cow: Skinny celestial cow is an insect of the genus Tenniu family. The main host plants are fir, spruce, linden pine, ichthyosis and other pine plants. They are distributed in Northeast China, Zhejiang and other places, and abroad in the Soviet Union, North Korea, Kuyei Island, Japan and other places. 5. Huatianniu: Huatianniu is a subfamily insect of the Gentian family. It has a near-square body shape, short head and chest, flat and wide coleoptera, females are significantly wider than males, head width is less than the front chest, antennae do not reach the end of the coleoptera, and the fourth section is shorter than the third or fifth section.
