As we all know, pests have a great impact on agriculture and can cause serious damage when they are serious. After pesticides were invented, although the pests were largely suppressed, at the same time, the impact of pesticides on the agricultural ecological environment was also very large. For example, pesticide residues such as foods and vegetables would be exceeded, posing a threat to human health, and in view of the insecticidal effect, The use of pesticides will cause pests to have a certain degree of drug resistance, so the effect will be greatly reduced. Today, with emphasis on environmental protection and concern for the development of ecological agriculture, it is necessary here to introduce several new types of insecticides that do not use pesticides and kill pests.
1. Electric shock killing lamp Electric shock killing lamp is based on the characteristics of insect phototaxis, trapping insects, and then using high voltage power grid to kill insects. A common 220V AC electric shock lamp costs several hundred dollars or so and can manage about 30 acres.
2. Wind suction type insecticidal lamp The insecticidal type insect lamp attracts insects according to the characteristics of the insect phototaxis, and then uses the wind energy system to inhale insect pests into the insect bag, and allows natural enemies such as parasitic bees to fly out of the escape hole. Top cloud Yunnong wind suction insecticidal lamp can also realize the network management of insecticidal lamp, use the mobile phone for corresponding remote control operation, very convenient.
3, sex attractant + trap Use of synthetic insect (female) sex pheromone, the male insect trap, so that female insects can not mating, spawning, thus controlling the number of pests. A sex attractant + a trap cost more than 20 yuan and can manage 0.5-1 mu of land.
4. Swatches Insects attract insects by their tropism at different wavelengths, and stick insects to viscose boards. A swatch cost 1-2 yuan, can manage 30 square meters of land.
5. Parasitoids Bees are parasitized in the larvae, cockroaches, and eggs of insects such as Lepidoptera, Coleoptera, Hymenoptera, and Diptera, feeding on their nutrients and destroying parasitic insects. One acre of land requires a parasitic bee cost of 30 yuan.
