How does the insecticidal lamp work? What are the types of insects? What is the effect of the insects? It is a problem we are concerned about. Let's take a brief look at some basic common sense of insecticidal lamps.
Insect lamp is the purpose of using the phototaxis of pests to attract insects. The trapped pests can be killed by the power grid on the insecticidal lamp. The killed insects emit sex hormones, which can attract more pests to achieve no use or less. The purpose of using pesticides to control pests. In order to verify the insecticidal effect of the insecticidal lamp in the fruit and vegetable garden, this test was specially set up. The insecticidal lamp made by Henan Yunfei Technology Development Co., Ltd. This product is a key promotion product of the National Agricultural Technology Extension Service Center. The frequency of the frequency vibration tube is 320-680 nm. The test site is located in the vegetable and citrus intercropping garden of Huolong Village, Panlong Town, Yunyang County, Chongqing. The citrus orchard is a five-year-old primordial garden, which has not been closed, and vegetable crops are planted between rows. The garden is 180 to 300 meters above sea level. The monthly average temperature during the test period was 25.02 °C. The test area is 200 mu, arranged according to 40 mu/ç›, and a total of 5 insecticidal lamps are suspended. Orchards and vegetable gardens are managed in the usual way. The lights were turned on on May 1, 2011 and turned off on September 30. The investigation was carried out 15 to 20 days after the light was turned on, and the trapped insects were classified by the Yunyang County Plant Protection and Quarantine Station.
Insect species: According to the results of the records, the pests that are trapped mainly include 7 species, 21 families and 34 species of insects. Analysis of the number of insects: From May 1 to September 30, a total of 153 days, 5 lamps led to the trapping of 34,250 heads, with an average of 6850 single-light traps, and a single lamp with an average of 44.8 insects per day. The number of single-light traps was 2,420 heads of Spodoptera litura and 2,535 heads of Spodoptera frugiperda, accounting for 35.3% and 37.0% of the total. The natural enemies affected a total of 85 beneficial insects, mainly Jigshen and scorpion flies, accounting for 1.24% of the total, and the beneficial ratio was 80.6:1.
The number of attracting insects is large and the variety is large. The number of attracting insects is large and the number is large. Especially for Lepidoptera and Coleoptera pests, the best results are obtained. For the citrus orchards, the main larvae, the leaf miner and the garden larvae are mainly The pest trapping effect is remarkable. The impact on the natural enemies is only 80.6:1. It can be seen that the use of the lamp to trap the pests has little effect on the population of natural enemies in the field, and can maintain the ecological balance of the farmland. The use of lower insecticidal lamps can control 30 to 40 mu, the pest control effect can reach more than 75%, the annual electricity consumption is 36 to 40 degrees, and the average annual prevention cost per mu is no more than 5 yuan, which can reduce the chemical every year. The application of the pesticide is more than 2 times, and the cost of saving pesticides per mu is 20 to 30 yuan. Therefore, the comprehensive evaluation believes that the use of insecticidal lamps in fruit and vegetable gardens is low in cost, good in effect, and environmentally friendly, and can be widely applied.
Organic Potato starch is produced by fresh potatoes. The potatoes are crushed, and the starch grains are released from the destroyed cells. The starch is then extracted and dried to powder. Organic potato starch can replace cornstarch in most cases as it is also a thickener for foods, such as soups, sauces, batters, baked goods, etc.
It contains typical large oval spherical granules, their size ranges between 5 and 100 μm. Potato starch contains minimal protein or fat. This gives the powder a clear white color, and the cooked starch typical characteristics of neutral taste, good clarity, high binding strength, long texture, and a minimal tendency to foaming or yellowing of the solution.
Potato starch contains approximately 800 ppm phosphate bound to the starch, this increases the viscosity and gives the solution a slightly anionic character, a low gelatinization temperature (approximately 140 °F or 60 °C), and high swelling power.
As a professional producer and supplier of organic potato starch, our starch is produced, processed, and stored in strict accordance with EU and USDA organic standards. It is 100% traceable.
