The frequency vibration type insecticidal lamp utilizes the characteristics of insect pests such as phototaxis, wave and color, and is accompanied by a vibrating high voltage power grid to contact pests. The Shanghai Vegetable District has introduced frequency-vibrancy insecticidal lamps since 2 XX years. Since 2002, it has been promoted on the basis of experimental demonstrations. The vegetable production bases in Shanghai Cai District, standardized vegetable gardens for vegetables, and export vegetable bases, etc. Each year, the application of insecticidal lamps is approximately 20 (2,X(T), 2(X) years to promote 2,110 units, and 2 (X extension to promote 2,108 units ( Among them, 341 solar-powered insecticidal lamps. In the Shanghai vegetable area, the insecticide lamp has an average single-lamp control area of ​​26 acres (2 acres per 667 acres) and a total of 22.8 million acres of controlled damage for five years. The time is 8 months. After using the insecticidal lamp, the use of pesticides can be reduced by 1 to 2 times per vegetable. According to the calculation of 4 months per vegetable, the use of insecticidal lamps will reduce the use of pesticides at least 2 to 4 times a year. Green leafy vegetables have shorter cycle duration and more pesticides are needed, cost savings of 19.97 yuan per mu for each crop, average planting of 2 crops of vegetables for 8 months, and 228,116 mu of insecticide lamps for 5 years. After using insecticidal lamps, the total cost savings were 9.111 million yuan.At present, the insecticidal lamp has become one of the main methods for pest control in Shanghai vegetable areas, and has many advantages, and it is welcomed by farmers.

1 Insecticide effect is obvious
1.1 Number of insect traps, large and multi-frequency vibrating insecticidal lamps have a good trapping effect on most of the common pests on vegetables, from 2 (X) 2 to 2 (11 cities in X years The survey and statistics on the culling and killing of experimental cemeteries used about 20 kinds of vegetable pests (Lepidoptera, Coleoptera, Orthoptera, and Homoptera) as main vegetable pests (clearly identifiable), and there were 9 kinds of vegetable insect pests that were mainly trapped and killed. In addition to the scarab, the major insect pests were P. xylostella and Spodoptera litura, which accounted for 33.8% and 28.7% of the total seizures in May-October, followed by the small tigers and silver. The Cryoptera zemailiae accounted for 10.7% and 14.6% of the total trapping t in May-October respectively, and the use of frequency-vibration type insecticidal lamps played an active role in the comprehensive prevention and control of leaf pests in the summer and autumn seasons. The average daily number of insects on a single lamp is less than a few dozens (a few grams) and more than a thousand (lkg). In the spring broccoli seedlings (covered with insect nets), a peak of one night can be induced to 5 The razor-backed Plutella xylostellae used insecticidal lamps to effectively reduce the density of insects in the field.
1.2 Hunting different pests at different times and at different times
1.2.1 There are obvious differences in the types of pest killing insect pests in different periods. Take the three-year observation in Jiading District as an example: During the period of 5 to 7 months, trap and kill the diamondback moth and adult tigers, side dishes, and side dishes. The moths accounted for 82.0%, 63.4%, and 49.2% of the total traps in the same period of the same year. The ground tigers accounted for 10.8%, 24.1%, and 17.3% of the total traps in the same period of the same year; after the October, the number of adults of Spodoptera littoralis was under the light. Straight up, accounting for 40.2%, 56.9%, 46.9% of the total trapping. By trapping insecticidal lamps, the number of pest populations is effectively controlled and the pests are eliminated before they are harmed.
1.2.2 There are obvious differences in the larvae of light-activated larvae at different time intervals. From Jiading to Western Organic Vegetable Orchard 2 (X) 2-1 (X-year observation from 3 years old, every night from 19:00 to 22:00, it is insecticide. The best time for the lamp to trap vegetable pests was 68.2% to 84.9% of the total trapping insects, and as time went on, the trapping amount decreased significantly after 22 o'clock, and the trapping amount only accounted for the total trapping amount.1 %-31.9% According to this feature, in practical use, the lamp can be turned off in the second half of the night depending on the situation, not only saving electricity costs, but also extending the life of the insecticidal lamp tube by a factor of two.
1.3 significantly lower the next generation of insect population density
1.3.1 Eggs fall from the field! Analyze the results of the investigation of the amount of oviposition and field larvae density in the fields of Xinghui and Long March bases of the Guangming Group's export vegetable base for two consecutive years; example. The average number of ovipositions per 100 plants in the hanging lamp area is 50%, of which the average number of eggs in the hanging lamp area is 2.1, and the number of eggs in the non-hanging lamp area is 4.3. According to the spawning characteristics of Spodoptera exigua, according to the export of onion acres planted 20 galaxy) plant, each egg block by the average 80 eggs calculated, non-hanging lamp area compared to the hanging lamp area average increase 35200 eggs per acre (80 / Block x2.2 blocks / hundred plants x 200 hundred plants / acre), calculated according to 80% of the egg hatch survival rate. Hanging lamp areas will increase by 28,160 larvae in the field. It can be seen that the use of insecticidal lamps can significantly reduce the densities of the contemporary and the next generation in the field, which not only achieves the insecticidal effect but also can reduce the amount of pesticides used, and also has a preventive effect on overwintering and the first generation of adults.
1.3.2 Analysis of field larvae The use of frequency-vibrancy insecticidal lamps can significantly reduce field densities in certain areas. According to the survey, the implementation base of the insecticidal lamp was an agricultural vegetable horticulture field. The number of insects per plant in the hanging lamp area (green vegetables) was 0.5, while that of the single plant in the non-lighting area was 6.5. In addition, according to the investigation of Maqiao vegetable gardening field (Hongdou), there were 3.5 heads of the beet armyworm larvae hanging lamp area and 47 heads of the unmounted lamp area, both of which had a difference of more than 10 times. In the hanging lamp area, the density of insect population in the field was significantly lower than that in the unlit area, and the field larvae suffered a significant reduction in the strain rate of the field larvae, thus reducing the number of medications and reducing the pesticide pollution to the environment. This played a multiplier role.
1.4 Basic safety of natural enemies in vegetable fields According to daily observation and analysis of the insecticidal lamp demonstration bases, the frequency and type of trapping insecticidal lamp traps have a wide variety of insect pests, but they have less entirability for natural enemies. For example, in 2003, a total of 18 days of light trapping in the bases of Minhang District was carried out from July fl to 29th. A total of 1287 insects were trapped and killed, and a total of 12 natural enemies were hunted, among which 5 were crickets, 4 were leeches and scoops. 3 insects. The ratio of benefits to harm is: 107. Fengxian District, the implementation of the base in the 24th of August 30th in 7d, 4 insecticidal lamp trapped a total of 6 natural enemies, 565 other insect pests, insecticidal lamp to attract natural enemies and pests than]: 94. The implementation base of Chongming County, August 3-22, passed the observation record of ZOd. The results showed that 22559 of insects were killed and killed, and 136 were beneficial insects, and the hazard ratio was 1,166. It can be seen that the frequency vibration type insecticidal lamp has little harm to natural enemies, and its use can play a role in killing insect pests, maintaining ecological balance, and reducing the use of pesticides. It is one of the more effective physical control measures.
2 Shanghai vegetable pest control lamp using technology
2.1 The application time and turn-on time of the insecticidal lamp and the main insecticidal species The application time of the insecticidal lamp in the Shanghai vegetable area is appropriate from April to November of each year'. The time of day light is from 7pm to 6am the next morning. As well. From May to July, the main insects were killed and killed by diamondback moths and small ground tigers. On the 8th to the last month, they mainly killed and killed Spodoptera litura and Spodoptera exigua. In special circumstances, the turn-on time can also be adjusted. The Hanging Lamp Density in 2 Different Areas and Hanging Lamp Height in Different Cultivation Modes
(1) In the case of a light source close to the urban area, the density of the hanging lamp is a single lamp control area of ​​about 6 acres, and the area of ​​a single lamp that is far from the urban light source is 35 to 40 acres. The use of insecticidal lamps should be concentrated.
(2) Hanging crops such as crucifers and scallions are usually at a height of 0.65 to 0.75 m, not exceeding 0.sm.
(3) Facilities for cultivation Shelving crops such as cucumbers, staring beans, lentils, tomatoes, etc., are usually about 1.om in height, and should not exceed 1.Zm.
(4) When the insecticidal lamp is used on aquatic vegetables such as Lingbai, the height of the hanging lamp should be continuously adjusted along with the growth of Lingbai. Because the main insect pest of Rhizocopteri is Eremospermum falciparum, it is relatively small and its flying ability is relatively weak. Hanging lights should not exceed 1.sm.
2.3 The high-pressure contact network of the insecticidal lamp must be brushed once a day. When brushing, brush gently along the high-voltage network cable with the brush, remove the bug's debris and other debris on the net, and it is beneficial to kill the insecticidal lamp. Today, Li Shengguo must clear the high pressure touch screen to turn off the power.
2.4 insecticide lamp bag must be cleaned once 3d If it is in the summer and hot season, it is best to wash once a day, is conducive to killing pests. The insect bag can be open at the bottom, which is conducive to daily pest removal.
2.5 Insect killing lamp is used together with insect nets and sexual attractants. Insecticide nets are linked to insecticidal nets, which can reduce insect infestation caused by access to pest control nets. Conditional townhouses, one per shelf, insecticide The effect is obvious. Insect killers and insecticides work better together. The insecticidal lamp and the beet armyworm sex attractant were combined, and the number of trapped and killing beet armyworms could be increased by 8 times compared with the insect lamp alone. The insecticidal lamp cooperates with Spodoptera litura sex attractant, and the number of trapping and killing of Spodoptera litura can be increased by 8-9 times compared with the insect killing lamp alone.
2.6 When the typhoon or strong wind is approaching, the insecticidal lamp shall be fastened so that it will not be shaken too much. After the end of each year of use, the insecticidal lamp shall be promptly collected, wiped clean, and then put in the paper tray to let people be ventilated and dry. warehouse. Before the second year of hanging the lamp, an inspection was carried out and it was found that the lamps and high-pressure contact nets were damaged and replaced in a timely manner to ensure that the hanging lamp can work effectively.
3 Several problems that should be paid attention to in the application of insecticidal lamps The effect of insecticidal lamps in vegetable production in Shanghai is obvious and is welcomed by vegetable farmers. Because of its application, it can reduce the amount of pesticides used, and it is beneficial to the protection of the environment. It is also supported by the government. Therefore, the application of insecticidal lamps in Shanghai vegetable production will gradually expand. However, several issues should be paid attention to in the future promotion.
3.1 Increase the intensity of testing and screening of insecticidal lamp products Due to the obvious application effect of insecticidal lamps, the market has great potential, and manufacturers and products of insecticidal lamp production are increasing. As a vegetable technology promotion department, the introduction and screening of new insecticide lamp products should be strengthened, and good products should be recommended to farmers. In the introduction of the same type of insecticidal lamp, several manufacturers can be selected to compare their product quality, product prices and after-sales service, allowing users to select the most suitable insecticidal lamp for production. At the same time, it can also encourage pest control lamp manufacturers to compete in quality, price and after-sales service, allowing users to get more benefits.
3.2 The use of insecticidal lamps should focus on the conspicuous insecticidal effect of insecticidal lamps is obvious, but should not be promoted in scattered farmers. Because the single lamp control area of ​​the insecticidal lamp is an average of 26 acres in the Shanghai vegetable area, the planting area of ​​the general vegetable planters is mostly below the ro-mu. Most of them are reluctant to use insecticidal lamps, and they are used according to the Shanghai vegetable area in recent years. Analysis of the situation of the insecticidal lamp, the use of insecticidal lamps to concentrate, contiguous best. Therefore, it is more appropriate to popularize the production of vegetables in Shanghai in vegetable horticultural gardens, vegetable bases for plants, export vegetable production bases, and large vegetable producers. Because these units and individuals, the larger area of ​​vegetables, is conducive to cloth lights; Second, they have a larger scale, there are professional and technical personnel, is conducive to the use and maintenance of the lamp; the third is the economic efficiency of the use of insecticidal lamps and Eco-efficiency is more obvious in these bases, and the operators of these units are more easily accepted.
3.3 Enlarging the application of solar insecticidal lamps The frequency-vibrant insecticidal lamp requires electricity. In some places, it is necessary to use wires and tree poles, which brings difficulties to use. Solar insecticidal lamps do not need electricity. It is more convenient to use wires at any site without wires. From the perspective of environmental protection and energy conservation, solar insecticidal lamps are the direction of future development and should be expanded. In particular, there are some lands where the wires are difficult to use. Solar-powered insecticidal lamps are the most suitable. However, the solar-powered insecticidal lamp has a limited amount of electricity and it is difficult to work normally in rainy weather. Therefore, at present, some qualified vegetable bases are advocating the use of solar insecticidal lamps and frequency-vibration insecticidal lamps in order to make the frequency-vibration insecticidal lamp work stably and Taipaeng insecticide lamp energy-saving and easy-to-use complementary advantages. Greater insecticidal effect.
3.4 Technical training to strengthen the use of insecticidal lamps The use of insecticidal lamps seems simple, but there are also many technologies, such as the density of cloth lamps, the height of hanging lamps and so on, which have a great impact on the insecticidal effect. If it is a solar insecticidal lamp, its installation location, the cleaning of the solar panel and the setting of the light-on time, the charging of the storage battery and the like are all required. Therefore, we must strengthen training on the use of insecticidal lamp technology, let the user know how to install, use and maintain the insecticidal lamp; how to make the insect lamp to extend the service life and maximize the effectiveness of the insecticide. At the same time, users should be trained in the knowledge of vegetable plant protection and safe electricity use so that insecticidal lamps can play a greater role in vegetable production.
