Timing is used to classify and count the types and numbers of trapped insects. The insect report lamp is collected once a week, and the insect report lamp is collected immediately after the lamp is closed. After collection, the number and type of trapped insects are counted according to the lamp. In particular, detailed statistics are recorded for the main forest pests in the area. Effectively grasp the dynamics of its occurrence and development. To facilitate the comparison of the effects of the two lamps, the amount of trapped insects was added every 10 days.
The forecast and analysis were carried out for the dead leaf moth and the blue-fall moth, and a total of 814 dead leaf moths and 386 blue-head moths were trapped during the period. Changes in the number of insect traps can be seen in the initial period of adult emergence of the leafworm moth in May, the peak period in August, the end of the period in September; the initial period of adult emergence of the bluefly moth is in late April, respectively, in May There were two peaks in July and the end of the period was in mid-August, which was in good agreement with the actual development and changes in the region over the years. It can be seen that the occurrence and development status of some adults can be grasped using the insect report light, and the occurrence period of the larvae can be predicted based on the change in the number of light-induced adults, providing a basis for timely guidance and prevention.
The pest report lamp can also timely monitor the occurrence of the type of pest, and through a comprehensive analysis to grasp its occurrence and development trends and potential hazards, and take timely response measures; therefore, it is worth to promote the forecast and prevention of forest pests Use, can also be used as a major tool for forest pest surveys.
Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.
