The yellow stick insects of stick insects trap pests.

Insecticidal technology of yellow label insect is a physical control technology that uses insects to turn yellow to trap and kill agricultural pests. Environmental protection, low cost, and annual application can greatly reduce the number of drug use. Using yellow paper (board) coated with adhesive to trap and kill insects can effectively reduce the density of insect population, without causing pesticide residues and insect resistance, and can treat a variety of pests at the same time. It can prevent and control small insects such as liriomyza sativae adults, whiteflies, aphids, leafhoppers and thrips. Blue board has a good trapping effect on leafhoppers, and can kill adults of various pests with sexual attractants.

Manufacturing method of yellow board: buy insect repellent paper, paint lemon yellow paint on lemon yellow wantong board (or plastic board or wood board) with an area of about 20cm× 30cm, and evenly coat a layer of insect repellent glue on both sides of the board (if there is no insect repellent glue, you can use rat repellent glue instead). It's simple to make. Paint wood, plastic or cardboard with yellow, and then coat it with butter or engine oil.

Requirements: double-sided trapping, paper should be flat and not curly, waterproof and high viscosity.

Suspension time: when used for control, at the early stage of pest occurrence; When it is used for monitoring, it should be hung from spring, with 0/~ 2 tablets per mu/kloc.

Field use: it is supported and fixed with bamboo (wood) thin sticks, which are distributed in a checkerboard shape in the field, and 20 yellow boards are evenly inserted and hung per mu. The height is slightly higher than the plant, and the effect is poor if it is too high or too low. Replace the paper or board when the sticky insect area accounts for more than 60% of the board area, and replace the board when the glue is not sticky. In order to ensure the adhesion of self-made yellow board, it is necessary to repaint 1 week or so. The hanging direction should be the east-west direction of the board.

Note: Used paper or cardboard should be recycled for centralized treatment, and yellow board should be used in conjunction with other comprehensive prevention and control measures to control the harm of pests more effectively.
