Fire ant, what does its Latin name mean? Invincible? According to public records, ants are difficult to control. The characteristics of being bitten by red imported fire ants are obvious. The wound itches, causing allergic symptoms such as burning, pain, swelling and pus discharge. Some allergic people will have severe anaphylactic shock, even dizziness, foaming at the mouth, difficulty breathing, convulsions, coma and so on. Red imported fire ants are widely distributed and are one of the most destructive invasive organisms. In recent years, the spread of Solenopsis invicta in China has accelerated, and the epidemic situation has further deteriorated. Solenopsis invicta has spread to urban green belts, vegetable fields and orchards.
According to experts, Solenopsis invicta has three major impacts on agricultural and forestry production. First, they feed directly on the roots, stems, leaves, fruits and underground parts of crops. For example, the output of sweet potatoes has dropped by 30%. Secondly, after the invasion of various agricultural areas, it is inconvenient for farmers to work in the fields, and the probability of injury is quite high, resulting in the loss of some land; Finally, after the occurrence of red imported fire ants, some pests and diseases are much more serious than before, which may be 50% to 80% more serious than those in areas where red imported fire ants do not occur.
According to the Ministry of Agriculture and Rural Affairs, Solenopsis invicta has spread to 435 counties in 12 provinces, autonomous regions and municipalities directly under the Central Government. The new report found that there were 19 1 counties in the past five years, twice as many as in 20 16 years. Lu Yongyao is the director of the Red Ant Research Center of South China Agricultural University, which is the only institution specializing in red ants in China. Since the first discovery of red imported fire ants, they have been breeding and living in China for at least 16 years, and new invasive pests are found in dozens of counties every year. However,? Due to the increase in the number of transported goods and suitable climatic conditions, the spread of red imported fire ants in some provinces has accelerated and increased in recent years. ? On March 15, many national departments issued a notice on the prevention and control of red imported fire ants, hoping that everyone would take precautions.
