Detoxification-saving efficiency-increasing trap-kill pest method
With the growing demand for pollution-free, green, and organic foods, minimizing pesticide residues and improving cost efficiency have become key concerns in modern agriculture. One of the most effective strategies to produce high-quality, safe agricultural products is through the use of non-chemical pest control methods. These techniques not only reduce environmental pollution but also help maintain a balanced ecosystem by protecting natural predators. Here are several efficient ways to trap and kill pests:
1. **Light Trapping**
Many pests are attracted to ultraviolet light with wavelengths between 330–400 nm. Commonly used tools include blacklight traps, frequency vibration lamps, and high-pressure mercury lamps. The Shundi insect lamp, which combines light, wave, color, and scent, is widely used. It is recommended to install one lamp per acre, operating from May to September, turning on at night and off in the morning. This method can eliminate over 1,000 species of pests, with a ratio of 1:100 for target pests versus beneficial insects. Each lamp can kill up to 2.8 kg of pests per night, which can be repurposed as animal feed. With a lifespan of 4–5 years and a cost of just 0.2 yuan per night, it is considered the most effective trapping method.
2. **Sex Pheromone Trapping**
This method involves using synthetic sex attractants to lure male pests into traps, preventing them from mating. A small amount of detergent is added to water basins placed 1 cm above the surface, with 5–8 traps per mu (approximately 667 square meters). This technique is especially useful for monitoring pest populations and controlling species such as the peach borer, leaf roller moth, cotton aphid, and diamondback moth.
3. **Sweet and Sour Traps**
A mixture of 6 parts sugar, 1 part wine, 3 parts vinegar, and 10 parts water, combined with a small amount of trichlorfon, is placed in pots around the field. These traps are set at a height of 1–1.5 meters and are effective against pests like the tiger moth, treple moth, pear mite, apple leaf roller, grasshoppers, and armyworms.
4. **Bait Trapping**
Roasted wheat bran or bean cake mixed with trichlorfon is used as bait. Placed in piles around trees or field ridges, this method effectively targets beetles, weevils, and ground tigers. It is particularly useful in newly planted orchards to prevent infestations.
5. **Yellow Sticky Traps**
Cardboard or fiberboard strips painted yellow and coated with motor oil or sticky adhesive are hung at 1–1.5 meters high. These traps are effective against whiteflies, leaf miners, and locusts. They should be re-coated every 7–10 days, and special armyworm boards are recommended for better results.
6. **Grass Trap**
Thick grass stems are tied to tree trunks in autumn to attract overwintering pests such as the American white moth, leaf miner, and aphids. Grass heaps in fields can also encourage armyworms to lay eggs, which are then destroyed by burning the grass.
7. **Plant Trapping**
Poplar and banyan twigs soaked in trichlorfon are placed in fields to attract larvae and other pests. Planting ramie around fruit trees helps trap chafers, while fresh paulownia leaves can be used to catch tiger larvae. All trapped pests should be removed and disposed of promptly.
By implementing these non-chemical pest control methods, farmers can significantly reduce the number of pesticide applications, typically by 1–2 times per year, leading to safer, more sustainable farming practices.
