Forestry pest control is an important part of forestry work. Forecasting and forecasting is an important part of forest pest control work. At present, forecasting and forecasting mainly adopts the traditional method of artificial surveying on the ground. It is difficult to obtain a wide range of advanced forecasting technologies and equipment at home and abroad, making the prediction and forecasting work far from meeting the needs of prevention and control work. Automatic pest reporting lamp is a new pest reporting tool based on black light trapping theory, light collection, electricity and numerical control technology. The current automatic insect forecast lamp is only used for the prediction of agricultural pests in individual places in China, and it is rarely used in the prediction and forecast of the national forest pests. In order to systematically master the patterns of the occurrence, occurrence and population dynamics of key forestry pests in Zhengzhou, improve forecasting accuracy and forecasting levels, and guide scientific prevention and control, the author worked in Zhongmu County and Xinmi City, Zhengzhou City in 2008-2009. Huiji District set up three automatic insect report lamp to carry out light induced survey. Through continuous 2a automatic insect report lamp monitoring, a total of 168 species of 145,004 head insects (a further 45 unidentifiable) belonging to 42 families and 11 families were collected, of which forestry pests were 7 orders, 36 families, 161 species and 144,008, accounting for 99.31%. The species accounted for 95.86%; beneficial insects had 6 orders, 6 families, 7 species, 996 heads, accounting for 0.69%, and the species accounted for 4.14%; the ratio of insects to insects trapped was 1:14.419, and the number of beneficial and harmful species was 1:23.14. The lamp-induced results show that insect pests have a large number of insect pests, and they have a large number of insect pests. The number of insect traps is very small. It can be used as an effective monitoring tool for forestry pests to monitor and control forest pests. There were 7 orders, 36 families, 161 species and 144,008 heads of forest pests in the three places, of which lepidoptera had 12 families, 120 species and 122 964 heads, and the number of species accounted for 74.53% of the total species, accounting for 85.39% of the total insect population; There are 25 species and 17 734 heads in 12 families. The number of species accounts for 16.05%, and the number accounts for 12.31%. There are 2 families, 5 species and 1012 heads in Hemiptera, the number of species accounts for 3.08%, and the number accounts for 0.7%. There are 2 species and 3 species in the family of Homoptera. The number of species accounted for 1.21%, the number accounted for 0.002%; Orthoptera 5 families 7 species 566, the number of species accounted for 4.3%, the number accounted for 0.39%; The order of 1 family 1 species 1331, the number of species accounted for 0.6%, the number accounted for 0.92 %; Diptera 1 class 1 species 398, the number of species accounted for 0.6%, accounting for 0.28%. The major forestry pests in Dengzhou City are Lepidoptera pests, followed by Coleoptera pests, which are leaf-feeding pests, pupae, and branch shoot pests. This is consistent with the actual occurrence of pests in forestry production. Light induced pests are used. It is of great practical significance to guide prevention and control work.

1 Materials and Methods
1,1 Automatic pest report lamp
1.2 Methods There are three representative standard sites distributed in the main tree species in Zhengzhou's main forest areas, each of which is equipped with an automatic insect report lamp. The three standard plots are located within the natural forest mixed forests of Donglin District, Donglin District, Zhongli District, and Niuzhuang Village, Dahe Office, Huiji District, and Shenxiandong Village, Jianshan Management Committee, Xinmi City. The investigation time was from March to September in 2008 and 2009. The collected insect specimens were collected once every 7 days, brought back to the room for identification, and then the types and numbers of pests and natural enemies that were trapped, as well as the male-male ratio were counted.
