Qingcheng County is located in the eastern part of Gansu Province. It has deep soil, long frost-free period, and large temperature difference between day and night. The fruit produced is large, colorful, brittle, and has a high sugar content. It is exported to Guangzhou, Shenzhen, and Hong Kong. It is the first batch of 100 pollution-free production bases in the country. At present, the 6 700 hm2 high-quality apple production base has begun to take shape, but for a long time, relying solely on chemical agents in the prevention and control of pests has led to increased resistance to insect pests, poor control efficiency, excessive pesticide residues, serious environmental pollution, and not only damage. Ecological balance, but also reduces the quality of the fruit. In order to coordinate with the construction of pollution-free fruit production bases, comprehensively improve the technological content of pollution-free apples, reduce the cost of pest control, and achieve the purpose of increasing production and income. From 2005 to 2006, we introduced frequency-vibration type insecticidal lamps to conduct trials to explore the absence of fruit tree pests. The effective way of preventing and controlling public hazards has received good results. Now the application is reported as follows.

It was worn together with the katana as a pair, known as daisho, which symbolized the social status and honor of the samurai. The wakizashi was often used for indoor fighting, where the longer katana would be impractical.

1 Materials and Methods
1.1 Test materials Frequency vibration insecticidal lamp, black light.
1.2 Methods
1.2.1 Tested in 6 villages in Gaolou Township (Hauji Temple, Liangjiazui), Baima Township (Guqi, Wangpan), Chicheng Township (Zhouzhuang, Chicheng) in the main apple producing areas in Qingcheng County. 30 orchards, 30 lamps, monitoring area 60~120 hm2.
1.2.2 Setting of insecticidal lamp The orchard is erected with a 3 m high pole, a tripod is fixed on the pole, and the lamp is fixed on the frame. The height of the hanging lights is 2 m and the distance between the lights is about 150 m. In the plots selected in each township, one set of frequency-controlled pesticidal lamps and black light lamps were compared and the lights were placed at different heights (1.5 m, 2.0 m, 2.5 m). The same set of test plots were as consistent as possible. .
1.2.3 The test period starts at the end of April and ends at mid-September. The light is turned on from 19:00 to 6:00 the next day. The date of the trapping will be recorded statistically every other day.
2 Results and Analysis
2.1 Frequency of insecticidal lamp traps 3 observation sites in 3 townships from April 23 to September 15; 2 a (years) total 541 800 insect traps, totaling 65 species, of which 5 601 were beneficial insects The hazard ratio was 1B107.1, the pests accounted for 99.1% of the total insect population, and the natural enemies accounted for only 0.9%. Natural enemies mainly include ladybugs, jealous bees, food flies and grasshoppers. The daily average number of trapped insects per lamp was 118.8, the lowest number, and the highest number was 204. All three sites have significant effects.
2.2 Insects attracted by frequency-vibration insecticidal lamp traps involved 5 orders, 15 families and 65 species (partial insects to be further identified), of which Lepidoptera was dominant, accounting for 70.9 % of the total insect population; Coleoptera followed, accounting for 28.6% of the total insect population; other 0.52%. The pests of lepidoptera mainly include Peach Moth, Peach, Plutella xylostella, Plutella xylostella, Pyrola xylostella, P. sinica, P. sinica, T. gracilis, T. gracilis, Spodoptera exigua, Dalbergia Moths, persimmons and tinea beetles, etc.; Coleoptera pests include black velvet beetle, terrapin beetle, quasi-parasites, longhorned beetles, leaf beetles, tadpoles, etc.; ; Diptera purposes are flies, mosquitoes and so on.
2.3 The relationship between trapping amount and month Figure 1 shows that the trapping amount is the most in July, followed by August. In other words, in contrast, July and August are the adult peaks of most insects. At the same time, the lamp can measure the peak period of specific insects, and in turn formulate control measures.
2.4 The relationship between the amount of insect attracting and the weather In the season of insect emergence, the statistical results from the 1st to the 10th of July (Table 1) showed that the number of insects in the windless and sunny days was significantly higher than that in the rainy and windy days, especially in the rainy days. The amount is small, so it is not advisable to turn on the lights in rainy days.
2.5 The height of the insecticidal lamp According to the statistics of 3 points and 3 groups (Table 2), the average daily trapping amount of a single lamp with a frequency of 1.5 m at the frequency of a vibration-type insecticidal lamp is 88.8, and the average daily weight of a single lamp at a height of 2 meters is 116.6. The average daily trapping amount of a single lamp at a height of 2.5 m is 77.7 heads, and the height of a hanging lamp is best at 2 m.
2.6 Comparison test between frequency-vibration insecticidal lamp and black light trapping effect showed that the trapping frequency of the frequency-vibration type insecticidal lamp was 1.94 times larger than that of the black light lamp, 1.63 times of the trapping species, 0.76 times of the beneficial insects, and frequency vibration type killing. The hazard ratio of insect lamps is 1B107; the benefit ratio of blacklight lamps is 1B43. The indicators show that the frequency-vibrancy insecticidal lamp has better prevention and control effects than black light and has a protective effect on natural enemies.
3 Control effect and cost analysis Frequency vibration type insecticidal lamp priced at 298 yuan each, wire, pole and other total 50 yuan, single lamp control area by 2.67 hm2, lamp life by 4 a (year); Turn on the lights for 10 hours (hours) in the evening, 146 days (days) per year, 30W for a single lamp, 0.5 yuan for each degree of electricity, and 21.9 yuan for electricity per year. The average annual control cost is 40.95 yuan/hm2. Chemical prevention and control only prevents Lepidoptera and Coleoptera pests from April to September each year. The average annual dose is 3 times, each drug cost is 45 yuan/hm2, the labor cost is 30 yuan/hm2, and the average annual prevention and treatment fee is 225 yuan/year. Hm2. Pesticide control costs accounted for only 18% of the prevention and control costs of pesticides, and control efficiency is much higher than that of chemical control; at the same time, insect pest resistance can be avoided, the amount of eggs laid by pests is greatly reduced, natural enemies are protected, and ecology is preserved.
4 Conclusion The frequency-vibration insecticidal lamp utilizes the characteristics of insect pests such as phototaxis, wave and color to set light waves within a specific range, use light at close distances, lure the adult insects with color and taste at a long distance, and avoid the insects. Natural enemy wavelengths and bands effectively protect natural enemies. The light is simple, convenient, safe, low cost, non-polluting, has significant economic, ecological and social benefits. It is an environment-friendly tool for preventing and controlling plant pests and has broad application prospects.
The construction of a wakizashi is similar to that of a katana, with a curved, single-edged blade and a circular or squared guard. The blade is typically forged from high-quality carbon steel and features a visible hamon, a distinct pattern created during the tempering process. The handle, or tsuka, is usually wrapped with silk or rayon cord, providing a secure grip.
In addition to its use as a weapon, the wakizashi holds cultural significance in Japan. It is considered a symbol of honor, loyalty, and tradition. Today, wakizashi swords are primarily collected as historical artifacts or used in martial arts training.
Overall, the wakizashi is a fascinating and important part of Japanese history and martial arts. Its compact size, elegant design, and rich symbolism make it a unique and revered weapon.
