Comparison of Effects of Different Types of Solar Insect Killing Pests

In recent years, frequency vibration trapping technology has been widely used in agricultural production as one of the green plant protection technologies. In order to test the effect of frequency-vibration solar insect killer on crop pests, in 2010, the author conducted a trial of trapping and killing insect pests in the orchard by Jiaduo frequency-vibrating solar insecticidal lamp and Miaohaha solar-powered insecticidal lamp. The results are reported below.
1 experimental design and methods
1.1 The site is located in Dengji Village, Caiwan Township, Quanzhou County. The experimental area is the Southern Shali Pear Orchard, which is 12 years old and has an area of ​​12 hm2. It is surrounded by mixed wood mountains, dry land and a small amount of paddy fields.
1.2 Materials and Contents From June 19 to August 23, 2010, 5 sets of Miaohaha Solar Insect Killer Lamps (supplied by Shanxi S&T Agricultural Tourism Co., Ltd.) were installed. Jiaduo Frequency-Responsive Solar Insect Killer Lamps (Yue Jia Polytechnics and Trade Co., Ltd. provided 1). Each Miaohaha insecticide lamp control area of ​​1 hm2, Jiaduo frequency vibration solar insect killer lamp control area of ​​2.17 hm2 per lamp. 2 The spacing of the Miao Miao Haha brand insecticidal lamp is 112 m. The Miaohaha brand insecticide lamp and the Jiaduo brand frequency vibration solar insect lamp have a lamp distance of 140 m.
1.3 Methods
1.3.1 Survey of Inducing Species and Inducing Species. After every day, the insects trapped and killed by the lamp were collected once every 2 days.
1.3.2 Control effect and scope investigation. Taking the Miaohaha Insect Killer Light as the center, there are altogether 4 treatments from 0 to 20, 20 to 40, 40 to 60, and 60 to 80 meters away from the lights. The center is centered on Jiaduo frequency-vibration solar insecticidal lamps. Set a total of 4 lamps from 0 to 30, 30 to 60, 60 to 90, and 90 to 120 m. At 20 and 40 days after the headlights of An Deng, 3 points were randomly sampled for each treatment, and 1 m2 was investigated for each sample. The number of major pests and the amount of insects that fell on the soil surface per square meter were recorded. The rate of pest reduction and the rate of egg loss were calculated.
1.3.3 Investigation of natural enemies. After the hanging lights, the trapped insects were collected every 2 days, and the natural enemies therein were identified and counted, and the proportion was calculated.
1.3.4 observation of the stability of the insecticidal lamp. The effects of wind and thunderstorm weather on the amount of attracting insects and product performance were mainly observed. We chose to conduct surveys on high winds and thunderstorms and count the amount of traps.
2 results
2.1 Insect Infestation Species and Insect Intakes From 32 observations (Table 1), the pests induced by the two lamps had 6 orders: Lepidoptera, Coleoptera, Homoptera, Hemiptera, Orthoptera, Diptera. Lepidoptera is mainly composed of codling moths, noctuidae, saturniidae, and moths; Coleoptera is mainly of the family Acrididae, Scarabaeoidea, and Celastridae; Homoptera is mainly composed of leafhoppers, Pteridaceae, and waxhoppers. The orthoptera mainly includes mites, centipedes and cockroaches; the dipteran pests are mainly fruit flies. The trapping patterns of the two lamps are basically the same.

Two Kinds of Solar Insect Killer Lamps in Pear Orchard

As can be seen from Table 1, in the 64-day test period, the Miaohaha insecticide lamp 5 leds averaged 26 809 insects, mainly Coleoptera, Lepidoptera, and Homoptera, and the average number was 20 932. 5 191 heads and 433 heads respectively accounted for 78.1%, 19.4%, and 1.6% of the total pests. Calculated with a control area of ​​1 hm2, an average of 1,787 insects per 667 m2 were seized; The total number of pests detected by the worm light was 284,939, which was 10.6 times that of the Miaohaha insecticide lamp. There were 245 136 heads, 15 584 heads, and 22 678 heads of Coleoptera, Lepidoptera, and Homoptera, accounting for 86.0%, 5.5%, and 8.0% of the total insect pests, respectively, calculated at 2.17 hm2 per lamp control area. With an average of 8 767 insects per 667 m2, the trapping effect on pests, especially Coleoptera and Homoptera, was significantly better than that of the Miaohaha insecticide lamp.
2.2 Control effect and scope After 20 days (July 9th) and 44d (August 2nd) of An Deng, investigations were conducted at 0-20, 20-40, 40-60, and 60-80 m from the Miaohaha insecticide lamp. And the main pests at 0-30, 30-60, 60-90, and 90-120 m from the Jiaduo frequency-vibrating solar insecticidal lamp, and the egg-laying rate of pests per m2. Due to the light occurrence of major pests of pear trees, two pests and eggs were not found in the two surveys except that 3 pear palates were found at 3 sites.
2.3 The impact on natural enemies can be seen in Table 1. The beneficial insects captured by the two types of lamp mainly include beetle, ladybug, hidden wing, and bee. For 64 d Mulahaha insecticidal lamp, the average benefit per insect is 452 per insect, and the hazard ratio is 1:59.3. The Jiadu brand frequency vibration solar insect killer has a total of 749 beetle insects, and the hazard ratio is 1 : 380.4. It shows that the trapping power of Jiaduo frequency-vibration solar insecticidal lamp on beneficial insects is obviously less than that of Miaohaha insecticide lamp.
2.4 Stability of the insecticidal lamp From Table 2, it can be seen that rainfall has little effect on the trapping amount of the two trapping lamps, and their performance is still stable. However, rainy days and no light during the day will affect the lighting time of the Miaohaha insecticide lamp.
3 Effect evaluation The above results show that there are 6 orders for pests baited by Jiaduo frequency-vibrating solar insecticidal lamp and Miaohaha solar-powered insecticidal lamp, and the insect trapping spectrums of the two solar insect killer lamps are basically the same. The trapping amount of the Jiaduo frequency-vibration solar insecticidal lamp is obviously greater than that of the Miaohaha solar insecticidal lamp, and the trapping power of beneficial insects is less than that of the Miaohaha solar insecticidal lamp. Jiaduo Solar Insect Killer Lamps have a larger control range and can be widely used for promotion. Miaohaha Insect Killer Lamps have a small control range, which facilitates the promotion and application of 0.67 to 1 hm2 small crop lands and orchards.
