Application of Insect Killer Lamps in Xinyang Vegetable Garden in Henan Province
The emergence of insecticidal lamps has changed the history that agriculture could only use chemical pesticides to kill insects and pests. The insecticidal lamp can effectively prevent and control pests, has a good trapping effect, has a large number of insecticides, is easy to use, simple to install, and environmentally friendly. Now insecticidal lamps have been used on a large scale in our country's agriculture, forestry, and orchards.
I. Insecticidal mechanism of insecticidal lamps
The insecticidal lamp uses light, wave, color, and taste to kill pests, uses light at a short distance, uses waves at a long distance, and is accompanied by high-voltage power grids outside the lamp, so that the insects fall into special insect-receiving bags under the lamp. To achieve the purpose of killing pests.
Second, the installation of insecticidal lamp
Methods In 2006, 70 lamps were installed in Dongyang Village and Pengcun Town, Dongyang Town, Xinyang, Henan Province. Each lamp had an area of ​​600 to 750hm2. The insecticidal lamp was installed around the vegetable field, and it was hung in accordance with conventional lighting methods. The height can be appropriately adjusted according to the height of the crop, generally controlled at a distance of 0.8 to 1.2 m from the crop, and fixed with a wire to prevent wind swaying. Select 220V AC power supply, follow the overhead line, prohibit the line from hanging anywhere, to prevent accidents, the copper core wire is not less than 2.5m. Single lamp trap radius 00m, according to the control area of ​​675hm2 cloth lamp, turn on the lights at 8 o'clock every night to 6 o'clock as early as the next day to turn off the lights, and collect the bag body, the insect traps must be completely killed and then buried. After turning off the lights, use a brush to clean the insects on the lamp. Clear the light box once a week and wipe the tube once. Hanging lights start from mid-May until the end of September.
Third, the effect of insecticidal lamp
1. Trapping and killing of pest species mostly involved Lepidoptera, Coleoptera, Orthoptera, Hemiptera, Homoptera, Diptera, Hymenoptera, 7 orders, 17 families, 36 pests, of which Lepidoptera pests accounted for 1. More than 70% of the total, followed by Coleoptera (see Table 1).
2. Number of traps and insect pests in large demonstration areas Fixed 2 insecticidal lamps, 1 lamp 0.8m high, 1 lamp 1.2m high, from 139d on May 14th to September 30th calendar, of which 14d on rainy days, outage failure 3d, actually recorded days 122d. Table 2 shows that the maximum number of insects per day is 507, and the average number is 273.
3. Natural Enemies Injury The main enemies of insecticide traps are grasshoppers and a small amount of bees and ladybugs, with a hazard ratio of 1:89.
Fourth, the effectiveness of insecticidal lamp
Demonstration area installed a total of 70 killing insecticidal lamps, lamps, poles, wires, installation and maintenance, manual operations and other fixed investment 78,000 yuan, according to each lamp can control the area of ​​600hm2, 70 lamps can control the area of ​​42000hm2, according to 5 The annual service life is calculated at a cost of 5.6 yuan per 667m2 per year.
According to our random survey of 10 model key households and 20 vegetable growers, the demonstration area has reduced drug use by 2 to 4 times compared with non-demonstration areas, reduced pesticide investment by 20 to 40 yuan per 667m2, and net savings of 15 to 35 yuan. Practice has proved that the use of insecticidal lamps is safe, reliable, easy, economical and effective. It is welcomed by a large number of vegetable farmers and can be widely promoted.
V. Summary of insecticidal lamps
1. The insecticidal lamp has a wide insecticidal spectrum and a large insecticidal capacity, and has a trap-killing effect on the main pests in vegetable fields.
2. Less damage to natural enemies can effectively protect natural enemies and promote and maintain ecological balance in the field.
3. The bollworm has the trapping effect on vegetables, and the control effect is obvious.
4. Insecticidal lamps use physical methods to kill insects, have no pollution, and are non-toxic to humans and animals.
