Light trapping is good for farming

There are many kinds of insects, many in quantity, and widely distributed. The prospects for development and utilization are very broad. At present, insect foods and insect feeds have been developed. As a good animal protein feed for raising chickens, fish and other famous aquatic products, it has won the favor of the majority of farmers, especially the breeding of forest frogs, bullfrogs and astragalus. Many insects have a phototaxis effect. Using this biological feature, insect traps are placed above breeding ponds and chicken houses during the night of summer and autumn to trap various insects for breeding purposes. Using insect traps to trap insects can not only reduce the harm of harmful insects to crops, but also can greatly increase the bait coefficient of aquaculture, promote growth, and increase yield and benefit. Tests have shown that attracting chickens by feeding chickens can increase the weight gain rate of broilers by more than 10% and egg production by laying hens by more than 15%. The technical points are as follows:
1. The choice of traps is best with black light, followed by ultraviolet light, ordinary fluorescent tube outsourcing blue-green or pink-violet silk has a better effect, and incandescent light is slightly less effective. This is because insects tend to have strong radiances toward blue, violet, and some ultraviolet light of short wavelengths, and are insensitive to red and orange light of longer wavelengths. The black light has soft lighting, suitable wavelength, strong penetrating ability, large trapping range, and best effect. The black light can trap more than 700 kinds of insects, especially the lepidopteran, moths, leaf moths and gold of the Coleoptera Tortoises, cockroaches, and leafhoppers of the same species are particularly attractive.
2. Insect traps are best installed with double traps. Single traps are hung low. The moths in the distance are not easily attracted. The trapping range is small; hanging high can attract insect moths in the distance. The trapping range is increased, but the moth is not easy to fall into the water, or it cannot be caught when the frogs, quails, etc. jump, and it consumes physical energy and reduces the trapping effect. If used for raising chickens, it will also cause inconvenience to chickens catching insects. Two-layer insect traps are used. One high and one low are for suspension. The low light is generally set at 20 to 40cm from the water surface, or about 0.5m above the chicken house, and the high light is about 2m from the low light. In this way, the two lights can do their best and the effect is very good. Note that there should be rain protection facilities on the insect traps, such as rain shades, to ensure safety.
3. Insect lamp turn-on time management practices have proven that turn-by-turn lights do not work well. Economic time is from 7pm to late at night 1 2
Time. Due to the most frequent insect activity during this time, the trapping effect was good. Various places can be adjusted flexibly according to the change of sunset dark time in different seasons.
According to the above method, with the light of 2 to 3 hours per night, the trapping insects of each group of insect traps are generally 2 to 5 kg, and the benefits are considerable.
