The red fire ants in Hainan are flooded: the whole people fight the battle of human ants
Scientific research shows that the reproductive ability of red fire ants is amazing, and each queen can lay an average of 1500-5000 eggs per day, so once the red fire ants enter a certain place, if they are not effectively controlled, they will develop at an alarming rate. Because this red fire ant has no natural enemies in Hainan Province, coupled with the warm winter in Hainan last year, it caused a large outbreak of the epidemic this year.
Lin Daoxi, deputy director of Luodou Farm in Wenchang City, Hainan Province: You want to eliminate it all, there is no such experience in China at present and there is no such method, where you can see, you kill it, it is in the dense mountain forest, then you can't kill it, you can't see it, after heavy rain, typhoons blow from the mountains, it will grow again.
Chen Liding, director of the monitoring and reporting station of the Agricultural Technology Extension Service Center of Wenchang City, Hainan Province: At present, our census area has 11 towns in the city, and there is a farm, and the epidemic of red fire ants has been found, involving an area of 68,000 mu.
Faced with the rampant red fire ants, the villagers came up with various ways to kill the ants.
Reporter: Now cut the nest open, how deep is it now?
Villagers in Shihou Village, Puqian Town, Wenchang City, Hainan Province: More than thirty centimeters have it, all come out, useless, boiling water is useless, or not.
Pan Jiachun, deputy secretary of the general branch of the party in Shihou Village, Puqian Town, Wenchang City, Hainan Province: The weather is dry, and now it is drilled very deeply, and this nest is estimated to be dug 0.8 meters -2 meters to the queen of the ant.
It is understood that if the queen can be caught, then the colony has no reproductive ability, generally 3 to 6 months can naturally die, but the speed of the queen transfer is very fast; then what about the effect of the fire, the villagers have tried.
According to experts, the most feasible method at present is to regularly release special baits for the prevention and control of red fire ants, which are mixed with food, which can be actively fed and transported back to the nest by the red fire ant foraging worker ants, and transmitted to various other ants through the active ingredients of the insecticide, thereby killing the whole nest of red fire ants. A few days ago, a truckload of insecticides uniformly distributed by the government was transported to Shihou Village in Puqian Town, and experts from the plant protection station instructed villagers on how to effectively deliver pesticides.
Xu Zhenmin, director of the plant protection station of the Agricultural Technology Extension Service Center of Wenchang City, Hainan Province: When you put it, you should pay attention to the fact that each anthill is about 15 to 20 grams, here is 500 grams, and 25 anthills should be placed.
Chen Liding, director of the crop disease and pest detection and reporting station of the Wenchang Agricultural Technology Extension Service Center in Hainan: For a week or half a month, we have to plan the control site, about 70 centimeters under the soil, if there is no ant appearing, you can determine that the nest is dead.
