Trapping and killing effect of Jiaduo Frequency vibrating Insecticidal Lamp on Chilo suppressalis

Rice stem borer (Chilo suppressalis) is one of the important pests in rice production in Wuchang City. In recent years, with the change of rice varieties and the warming of climatic conditions in our city, the occurrence and harm of rice stem borer (Chilo suppressalis) is becoming more and more serious. According to the investigation this autumn, the average number of insects per mu of individual varieties of Wuchang reached more than 20, 000, and the highest number in key areas was as high as 60, 000, even more than 100000, which is rare in history, whether at home or abroad. In order to further control the damage of Chilo suppressalis, explore new ways to control Chilo suppressalis and reduce the pollution of insecticides to rice. This year, our city set up Jiaduo vibrating frequency lamp to control rice stem borer in Lianhua Village, Wuchang Town, and achieved good results. The test results are summarized as follows:

I. Materials and methods

Jiaduo vibrating insecticidal lamp: provided by Henan Tangyang Jiaduoke Industry and Trade Co., Ltd. The model is PS~15 with a power of 30W. Since June 20, the trapping area of the lamp is 60 mu, and the lights are closed during the day and turned on at night, both of which are controlled by photosensitive current switches. The number of adults trapped and killed by long people was recorded every day to regularly investigate the changes of moths after trapping and killing, and the control effect of Chilo suppressalis larvae in the field was investigated in autumn.

2. Test results

1. Trapping and killing effect on adults of Chilo suppressalis the multi-frequency insecticidal lamp has a good trapping and killing effect on adults of Chilo suppressalis. This year, Sun Guanghao's family in our city trapped and killed a total of 852 adults of Chilo suppressalis from the setting of lights to the end of oviposition, of which the proportion of female moths was 3.7 ∶ 1. The female-to-male ratio of Jiaduo frequency vibration insecticidal light was higher than that of female and male moths in the field. The ratio of male and female moths in the field is 1.8 ∶ 1. By trapping and killing adults, the number of adults of Chilo suppressalis in the field can be significantly reduced. According to the discovery of poplar spreading rice tillering fertilizer at the end of June, in the effective control area of Jiaduo frequency vibrating insecticidal lamp, the adults of Chilo suppressalis startled by fertilizer are at most several per mu, but not in the effective area. Each handful of fertilizer can startle 3 and 5 adults of Chilo suppressalis, most of which are 7 and 8, or even more than 10, and an average of 40 adults per mu can be startled. (surprise observation).

2. Jiaduo frequency vibrating insecticidal lamp can reduce the number of eggs in the field of Chilo suppressalis. In the effective control area of Sun Guanghao's family in Lianhua Village of our city this year, the number of eggs falling in the field is only 1 stroke, 10 pounds, 1 stroke, 20 pounds. On July 5, the nearer to the lamp in the survey control area, there are more egg masses, but in the park with the lamp as the center and 100m long as the radius, there are an average of 0.137 eggs per square meter and 1.49eggs outside the control area.

3. Jiaduo frequency vibrating insecticidal lamp effectively controls the occurrence of Chilo suppressalis larvae in the field. According to the investigation on September 30, there are 0.125 Chilo suppressalis per square meter in the Jiaduo frequency insecticidal lamp control area, but in the non-control area, it is 120m away from the insecticidal lamp. The varieties are all Wuyou Dao No.1. They are all the land of Sun Guanghao's family (Sun Guanghao's family grows rice for 16 years). The level of fertilization and the growth of rice are basically the same. The control effect reached 69.3%.

The lamp test shows that Jiaduo frequency vibration has a good insecticidal effect on rice stem borer. The effect can reach 69.3%. The use of insecticidal lamps can reduce the pressure of chemical control, can not pollute the environment, can produce rice for the production of green food, and the lamp is simple, the cost is not high, the electricity charge is less than 30 cents a day, and it is easy to operate, so it is well received by the majority of agricultural products.
