Eggplant tea (Polyphagosaponus latus Banks) (also known as Hemitarsonemus latus Banks), also known as side-to-multi-food oysters, tea semi-cholines, tea leaves, etc., are classified as Arachnida, Acarina, Ape. Line branch. Harmful eggplants, tomatoes, spicy (sweet) peppers, potatoes, red beans, beans, cucumbers, and other vegetables.
Hazardous features After the eggplant fruit is damaged by the tea plant, the original color of the eggplant disappears and gradually turns dark brown. Especially at the end of the fruit is more pronounced. If it is seriously damaged, the surface of the fruit becomes hard, and as the eggplant grows, the fruit cracks and cannot be eaten. After the eggplant was damaged, the upper leaves were stiff and the leaf margins curled downward. The back of the leaves is brown and glossy with oily luster. If the new shoots are all affected, fertility will also decline significantly. Tea is also an omnivorous pest, and eggplant is the most vulnerable crop.
The female form is about 0.21 mm long, elliptical, yellowish, translucent, 4 pairs, and the 4th pair is slender. Male adult carcasses are narrow, long, nearly diamond-shaped, about 0.19 mm long, milky to pale yellow. 4 pairs, 4th pair is thicker. Cub body is more fine, with 3 pairs.
Habits: 25 years to 30 generations in 1 year, generally wintering in females, warming in winter, and under greenhouse cultivation conditions, can grow and reproduce all year round, and the overwintering period is not obvious. The cockroach is very warm and wet, showing obvious tenderness. Under conditions of moderate temperature, continuous rain, and weak sunshine, their populations grow rapidly and cause serious damage. Long-distance can be spread by wind; close-range propagation is carried by humans and crawling by carcasses. Natural predators have predatory mites (Nyquist obliquus, Dew's obtuse cockroaches, tumors long beard cockroaches), thrips, florets and so on.
Prevention and control methods: Tea yellow has been eating and miscellaneous, endangering various vegetable crops. In recent years, it has caused serious damage to vegetables and comprehensive control measures should be adopted.
1. Agricultural control measures Strengthen field management, nurture strong seedlings, increase ventilation and light transmission, prevent leggy and madness, effectively reduce the relative air humidity in the field, and ecologically break the climatic pattern of the occurrence of the tea plant, and reduce the damage. 1 Select a site with good lighting conditions, high dry terrain, and well-drained land. 2 rational dense planting, high and narrow width of row cultivation. 3 The application of organic fertilizer, topdressing nitrogen, phosphorus, potassium fertilizer, control the amount of water, after the rain to strengthen the drainage, shallow flooding. Timely pruning and reasonable density. 4 Clear the weeds in the field and the ground and the debris and reduce the number of insects. Diligently inspect and find the affected plants and control them as soon as possible; spray control should be applied when field roll leafing rate reaches 0.5%.
2. Chemical control measures Solanaceous vegetables enter the continuous harvest period in the middle and later stages of growth. It is also the peak period of the tea plant. The biological agent is the first choice for the application of pesticides, followed by the high-efficiency, low-toxicity, low-residue chemical pesticides. Good safety interval. The spray application is mainly on the young leaves, tender stems, flower organs and young fruit of the upper part of the plant. 1.8% Qi Qi Su (avermectin, efford, etc.) EC 3000 times spray, safety interval of 7 to 10 days. 20% compound Liuyangmycin EC 1000 times spray, interval 7 days. 73% Chrysanthemum EC 2500x spray, interval 7 days. 15% of the fast-acting ketones (Erbene, Pyrene, etc.) are sprayed 3000 times with 40 days intervals. 5% Nisolut EC or WP 1500 times spray, 60-day interval.
Same as round type LED Surgical Lamp, the flower type operating lamp also can add camera system, the camera system can choose SD or HD, depends on hospital requirment, even though single dome or double dome, both can add camera system, can choose camera built in or built out. The camera system is Sony brand, we have use it for many years, the system is stable. as recording and teaching is part of Cuntinous Medical Education (C.M.E) within and outside the O.R/ Hospital, our solution is to achieve both. The image resolution of full HD medical grade digital camera can be as high as 1920*1080 pixels.
