Recently, Spodoptera exigua has been damaged in some summer corn fields in Beijing. Spodoptera exigua, also known as Spodoptera exigua, is a worldwide distributed and intermittent omnivorous pest that contains more than 170 plants such as corn, cotton, sugar beet, soybean, cabbage, and tomato. The Spodoptera exigua larvae often cluster on the back of the corn leaves, and the remaining part of the leaves after the leaves have formed a "rotten window-like" broken leaves. All districts and counties should closely monitor their populations in the field and take preventive measures in time to prevent the insects from damaging the summer corn. Specific prevention measures include:
Timely eradication of ground, weeds, field ridges, and field weeds to reduce the pests' breeding sites; black light, frequency-vibration lamp or sex attractant, sweet and sour liquid are used for trapping and killing; 20% diflubenzuron is selected 1,000 times liquid spray control or 16000 units of Bt emulsion sprayed 100 times per acre; or use 10% demulsification 1000 times liquid, 5% stuck oil 1500 times, 50% high efficiency cypermethrin 1000 times plus 50% Xin Sulphur-containing EC 1000 times, or plus 80% dichlorvos EC 1000 times spray.

Description:
A double-lumen Endotracheal tube is a type of endotracheal tube which is used in tracheal intubation during thoracic surgery and other medical conditions to achieve selective, one-sided ventilation of either the right or the left lung.
There are several conditions that may make one-sided lung ventilation necessary. Absolute indications include separation of the right from the left lung to avoid spillage of blood or pus from an infected or bleeding side to the unaffected side. Relative indications include the collapse of one lung and the selective ventilation of the remaining lung in order to facilitate exposure of the anatomical structures to be operated on in thoracic surgeries.
Construction:
Consist of PVC tube, cuff, inflation lumen.
