Pine caterpillar is one of the major forest pests and diseases in China. The pests are becoming more and more serious to the forest, and the task of prevention and control is more and more arduous. Forecasting and forecasting work is of great significance in the macro-control of pine caterpillar disasters. Timely and accurate provision of basic information on pine caterpillar pests and disasters can provide the first material for the prevention and control plan formulation, and provide a basis for effective implementation of prevention and control decisions. Automatic pest test lights can be applied as much as possible in the prediction of pine caterpillar disasters.
Within the monitoring coverage of the central survey point, the selected route is required to have a certain representativeness, and it must cover 90% of the disaster area. Under normal circumstances, a more fixed tour route can be designed as a route. "At the same time, according to actual needs, temporary routes should be set up at any time in the area of ​​occurrence. Select the sampling point and place the automatic insect detection light. "In the Changfa District, set the trapping point every 102,000 hm/1! In the sporadic area every 40,000 hm/1. The automatic insect detection lamp or trap must be It is hung on the crown of a higher position or well ventilated place. At the end of the weekend, it is necessary to set up an automatic insect detection lamp or sex trap to be recovered after the end of each generation of adult worms, which can be taken daily or every other day. Observe the amount of adult trapped and record the results in the form.
Through the correlation data measured by the automatic insect detection lamp, the monitoring data of each generation of adult or next-generation larvae are analyzed, and the number of distribution points, distribution density, and location are gradually adjusted, and the occurrence range of the next generation larvae according to the number of contemporary adults is finally realized. And early prediction of the extent of occurrence.
Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
