The struggle against mosquitoes in the sheepfold

The struggle against mosquitoes in the sheepfold

Fifth grade Tang of complete primary school in Qiaotoupu Town, Jianghua Yao Autonomous County, Hunan Province

My family lives at the foot of the mountain in the west of Jianghua Yao Autonomous County, and there are more than 200 sheep in my family. It blows from Xia Feng. When the weather is hot, ewes begin to give birth to lambs. The fight against mosquitoes in my sheepfold has begun.

There are many mosquitoes in the mountains, such as long-legged mosquitoes, big black mosquitoes and flower mosquitoes. They buzzed in, gathered in the sheepfold and began to feast.

Sheep are getting thinner and thinner. Grandpa sees it in his eyes and is anxious in his heart. He began to kill mosquitoes in different ways.

Grandpa collected wormwood from the mountain to burn. Smoke billowed from the sheepfold, which made my eyes water. The sheep were frightened and broke through. The big sheep looks for the little sheep, and the little sheep calls for her mother. The sound of "baa baa" continued, and the scene was in chaos. The mosquitoes subsided and temporarily retreated to the mountains. The smoke receded, the sheepfold returned, and mosquitoes made a comeback.

Grandpa had to buy some mosquito-repellent incense from the market. But the sheepfold is too big, and lighting a circle or two of mosquito-repellent incense is of no help at all. Grandpa put a little everywhere. One day, the mosquito-repellent incense was kicked down by a sheep, which almost caused a fire.

I suggest grandpa try the mosquito killer. We took a fancy to a mosquito killer in the supermarket. There are several pillars outside this lamp. There is a layer of red barbed wire on the pillar, and there is a cathode fluorescent lamp inside, which can shine to attract mosquitoes.

Grandpa said doubtfully, "Isn't there a fluorescent lamp at home? Haven't you killed mosquitoes? "

I told him that the lights in the mosquito killer were scientifically processed. That layer of barbed wire is the power grid, which can electrocute flying mosquitoes.

The shop assistant told us that there are many kinds of mosquito killers. Some lights can emit mosquitoes' favorite 365nm light waves, some lights can simulate people's breathing sounds, and some lights can emit mosquitoes' favorite smells ... We chose two lights, one with mosquito-attracting light waves and fan-assisted lights, and the other with mosquito-attracting light waves and smells to lure the enemy.

At night, we hang these two lamps in the sheepfold and plug them in. The lamp emits soft purple light, which is said to be the favorite color of mosquitoes. Sure enough, in a short time, many mosquitoes gathered by the lamp.

The next morning, grandpa took down two lamps and emptied the mosquito bodies from the lamp tray. Wow, there are two piles. How big they are!

Mosquito control lasted for more than a month and achieved brilliant results every day. But my hands and feet are still bitten by mosquitoes everywhere. There are so many mosquitoes here.

I think the reason why there are so many mosquitoes is that our environment is getting worse and worse and there are fewer and fewer beneficial insects. Look at my hometown. There are fewer frogs, fewer dragonflies, fewer birds and fewer geckos ... Mosquitoes have no natural enemies and are becoming more and more rampant. If we want to completely eliminate mosquitoes, we must protect the ecological environment and protect beneficial insects and birds.
