Willow tree

Willow tree, Nephila, Coleoptera, Cerambycidae. The hosts mainly include mulberry, black peony, paulownia, maple, platanus, weeping willow, fig, sorghum and so on. Hazardous features: Adults feed on leaves and branches; larvae feed the cortex and xylem of the branches, weakening the tree vigor, and severely causing trees to die. Morphological characteristics: adults dark brown, body surface grayish blue or yellow fuzz. The center of the thoracodorsal plate has a pair of kidney-shaped white furrows, rows, small scutellum tongues, covered with white hairs. The scaly fin base is covered with black particles at 1/4 and irregular white cloud-like spots on the wing surface, showing 2 to 3 longitudinal rows. On both sides of the body's abdomen, there is a white vertical band from the back of the eye to the end of the abdomen. The eggs are 7 to 9 mm long and are milky white at the time of their initial production. They gradually turn yellow-white, long oval, and slightly curved. The larva is slightly flat, milky to yellowish-white, slightly flattened, dark brown, rectangular, 1/2 indented into the chest, exposed black, and yellow-brown. The front thoracodorsal plate is nearly square and orange-yellow, with concave troughs on both sides of the mid-rear part, fine engraved dots on the front, dark brown granular granules on the posterior part of the back, white backs on both sides, orange and yellow on the back. One spot. The back chest and 1-7 abdominal section dorsal, abdominal mask bubble step. The beak is 40 to 90 mm long, colostrum is white, and the latter half is tan. Habits: 2 to 3 years and 1 generation, adult or larvae wintering in the tunnel. The overwintering adults bore their trunks in May-June by biting the feathered holes. After more than 10 days of feeding, they began mating and spawning. The eggs were prolific in the underside of the trunk or slanting branches, especially in branches within 2 meters from the ground. The average length of 15 to 20 centimeters in length can be spawned. When spawning, oviposition of the oval-shaped faba bean size is first made on the branches, and after 1 egg is produced, the bark around the trough is placed. Biting into small pieces of wood to block the spawning mouth, the newly hatched larvae feed on the phloem of the trunk, and the bark of the damaged area turns black and soon splits. After about 25 days, the larvae invade the xylem. Adults live for about 1 month. Each female lays between 20 and 40 eggs, and eggs last for 10 to 15 days. In mid-June, it enters the hatching period. The newly hatched larvae cut the cortex into triangle tunnels. Wood chips and feces from the borehole Excretion, making the bark outered and dilated, is an important feature to identify the hazards of Cloudbill. After entering the xylem, the direction of the drill hole is indefinite, and it leans upwards in the thick branches, sloping to the inside of the twigs and then pecking down to the pith, passing through the defecation hole at a certain distance outward, biting off the wood chips. The excreted and excreted feces are placed first behind the body, accumulated to a certain amount and then pushed out of the hole. The larvae's range of tunnels are basically free of wood chips and insect excrement, and the rest are filled with sawdust and feces. In late autumn, the larvae survive winters in addition to a dormant room, and continue their activities in April of the following year. From August to September, the mature larvae in the kidney-like diverticulum have metastasized. 20 to 30 days in the flood season, wintering in the cricket room after eclosion, and the tree emerged from May to June in the third year; the adults in the third year and the fifth year to June in the fourth year emerged from the tree. Control methods: First, from April to May, the entomopathogenic nematodes were used to inject water into the holes, and nematodes were used to kill the larvae of the longhorn beetles. Second, from June to August can be artificially caught adult (in this case Tianying ovulation spawning peak period). 3. After 6 to 8 months, it will be effective to dry with 10% of a 20% methicone phosphate 25 to 30 times liquid. 4. From July to August, apply a mixture of 20% chrysanthemum emulsifiable concentrate 10 times or 1:20 kerosene and deltamethrin on the newly spawned trough to kill the newly hatched larvae. V. The larva hatching period from September to October was perfused with white wine and dichlorvos in a 1:1 ratio. (Source: China Flower News, Shi Dingkang)

Active Pharmaceutical Ingredients

Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
