With the gradual deepening of WTO accession and IPM (integrated pest management), as well as the development of agricultural production and the gradual improvement of living standards, people are increasingly demanding food quality and safety, and their awareness of protecting the ecological environment is increasing, and for safe food. The demand is also growing, and this demand trend has raised new issues for agricultural production, and it has also brought new opportunities and challenges to plant protection. The application and promotion of insecticidal lamps is a new prevention system and measures that have emerged as a result of reducing pesticide pollution, avoiding pesticide residues and reducing pesticide resistance.
1 The principle of prevention and control utilizes the characteristics of light, wave and other characteristics of pests, setting the frequency band of light and the frequency of the wave within a specific range, using light at close distances, trapping pests with waves at a long distance, and vibrating high voltage of lamps. The grid hits and kills the pests and falls into the insect bag to kill the pests. By killing adults and reducing the amount of eggs in the field, the amount of pests in the field can be further controlled to achieve safe control.
KEY TECHNOLOGY
1) Hang the insecticidal lamp on a fixed object, and the hanging height is higher than the crop crop. You can use the poles, cement columns, etc. at the edge of the field to fix it on the top, and the height of the insects from the ground is 1.5m.
2) Turn on the power according to the specified voltage of the insecticidal lamp (AC 220V or 380V, DC 12V or 24V), turn on the switch, and the indicator light will turn into normal operation.
3) From the end of April to the end of August, the lights can be trapped to kill the wintering or the first generation of adults; the lights are turned on every day from 19:00 to 5:00.
4) Pest collection: The insect bag is hung in the lower part of the lamp. The pests are touched by the high-voltage power grid and then fall into the bag, and cleaned up in time to ensure continued use.
5) Cleaning of worm scales: When the high-voltage power grid is covered with adult worms, it is necessary to clean the worm scales with a brush to reduce the trapping effect.
3 Insecticidal lamp Trapping pest species, the effect
1 The active time of pests is investigated from April to September every year. In June and July, the amount of insecticides was high, and the most was in July. During the period from 20:00 to -22:30 every day, the amount of insects is large, and during the investigation, the activity of pest activity is directly related to the weather changes such as wind direction, temperature, weather and sunny weather. The temperature is high and the amount of insects is too high when the weather is fine.
2 The results of the decoy species survey showed that more than 60 species of pests were trapped, among which lepidopteran pests accounted for more than 70% of the total. The main species are: armyworm, cotton bollworm, small tiger, earth tiger, cabbage night moth, beet armyworm, silver beetle, lettuce winter moth, scorpion yellow moth, scorpion moth, yellow caterpillar caterpillar, yang moth , human smudged moth, scorpion moth, grape hawk moth, stem borer, rice blast, rice leaf roller, corn borer, soybean borer, cotton leafhopper, grasshopper, pod wild, large bridgeworm , Star White Snow Moth, Bean Moth, Bean Leaf Leaf Wild Donkey, Plutella xylostella, Rice Water Weevil, Northeast Black Scorpion Golden Tortoise, Dark Black Stork Golden Turtle, Cloud Stork Golden Turtle, Copper Green Lijin Turtle, Oriental Stork, Whitebacked Flycatcher , Daqing Ye Yu.
Number 3 is provided decoy three survey points, each point of the lamp 5, the findings show that the first point average attractant 219.66 / D, a second point average attractant 347.81 / D, a third point average attractant 478.92 / d. Taken together, the average single-lamp trap is 69.8 heads/d.
The above data show that the frequency-vibration insecticidal lamp has a good trapping effect on a variety of pests. The use of the frequency-vibration insecticidal lamp not only has significant economic benefits, but also greatly reduces the density of pests and insects, while reducing or even avoiding the application of chemical methods. Improve the quality and safety of agricultural products, enhance the competitiveness of agricultural products market, and promote a virtuous cycle of ecosystems.
Question 4 Application Frequency insect lamp should be noted
1) The application of insecticidal lamps to control pests must be done by farmers and negotiated together for large-area applications.
2) Special person management must be set up to clean the lamps in time to ensure the control effect.
