Red fire ant control program: what are the hazards of red fire ants? How to eliminate red fire ants

Red fire ants, do you know this pest? What kind of understanding do you have? Red fire ant is a very harmful pest, if there is such a pest invasion is very terrible. In order to strengthen the prevention and control of invading red fire ants, continue to adhere to the north-south defense line and adopt containment strategies, promote regional joint prevention and control, and strengthen strengthening measures such as the consolidation of the southern defense line, the elimination of sporadic spots outside the defense line, and the expansion of surveillance points to grasp the epidemic situation. In order to make effective use of control resources, the Prevention and Inspection Bureau and the National Red Fire Ant Control Center will continue to provide local government administrative and technical support to control the spread of invasive red fire ants.

Strengthening the containment, prevention and control of sporadic epidemic spots on the Southern Defense Line

The International Union for the Conservation of Nature and Natural Resources (IUCN) is listed as one of the top 100 malignant invasive red fire ants. It has been invading Taiwan for 15 years, but it has not been cured yet, and there are even signs of gradual spread in Taiwan's epidemic areas. In addition to causing harm to melons and fruits, red fire ants will cause burning and pain if human beings are bitten, and in serious cases, they may cause allergies or shock.

At present, the invading red fire ants are mainly distributed in northern Taiwan (Shuangbei, Taoyuan and Hsinchu) and occur locally in Miaoli, while there are sporadic cases in Taichung, Chiayi (county), Tainan, Kaohsiung and Ilan. At the present stage, the Council of Agriculture adopts the prevention and control strategy of "containment" to enclose the invading red fire ants between the Tanshui River and Touqian Creek to prevent them from spreading outside the line of defense. The Bureau of Prevention and Inspection stated that outside the main areas in northern Taiwan, a small number of sporadic outbreaks of invading red fire ants occurred in Gongliao District of New Taipei City, Gongguan Township, Shitan Township, Touwu Township, and Causeway Township of Miaoli County. The Bureau has asked the Red Fire Ant Center to carry out the fight on a project basis to reduce the risk of spread. As for the cases in Taichung, Chiayi (County), Tainan, Kaohsiung and Ilan, the relevant authorities have been asked to strengthen supervision and control, and the Prevention and Inspection Bureau and the Fire Ant Center will continue to monitor and provide technical support with a view to completing the fight in 108 years. In addition, it will also expand the comprehensive reconnaissance work in Taoyuan City, Hsinchu County and Miaoli County, strengthen tracking control effects and grasp the leading edge of the spread of red fire ants, which can be used as a reference for future review and adjustment of control strategies.

In order to implement the containment and prevention of the Southern Defense Line, for the part of insufficient resources of the local government, in 108, the Prevention and Inspection Bureau appointed the Fire Ant Center to assist Hsinchu County and Miaoli County to carry out three comprehensive prevention and control work, and to give immediate emergency prevention and control to sporadic occurrence sites to ensure the containment effect. The Bureau of Prevention and Inspection stated that outside the main areas in northern Taiwan, a small number of sporadic outbreaks of invading red fire ants occurred in Gongliao District of New Taipei City, Gongguan Township, Shitan Township, Touwu Township, and Causeway Township of Miaoli County. The Bureau has asked the Red Fire Ant Center to carry out the fight on a project basis to reduce the risk of spread. As for the cases in Taichung, Chiayi (County), Tainan, Kaohsiung and Ilan, the relevant authorities have been asked to strengthen supervision and control, and the Prevention and Inspection Bureau and the Fire Ant Center will continue to monitor and provide technical support with a view to completing the fight in 108 years. In addition, it will also expand the comprehensive reconnaissance work in Taoyuan City, Hsinchu County and Miaoli County, strengthen tracking control effects and grasp the leading edge of the spread of red fire ants, which can be used as a reference for future review and adjustment of control strategies.

To prevent and control red fire ants, it is necessary to block the migration of contaminated soil.

The invading cases of red fire ants occurred in 107 and 108 years, and it was found that when conducting large outdoor exhibitions, the invading red fire ants moved into the earthwork and planting along with the layout of the site, so the Prevention and Inspection Bureau reminded all authorities to strengthen the control of earthwork and planting movement. In particular, when dealing with project bidding, the non-invasive red fire ant clause should be included in the contract and taken as the focus of completion and acceptance, so as to avoid the accompanying spread of invasive red fire ants.

In order to grasp the epidemic situation and the effectiveness of prevention and control, and to strengthen the vertical and horizontal liaison and cooperation between the central ministries and local governments, the Prevention and Inspection Bureau regularly invited the central ministries, local governments, experimental and research units, experts and scholars and the fire ant center to hold implementation meetings to review the control measures and effectiveness. And continue to promote joint prevention and control across counties and cities, nursery planting and construction base inspection, earthwork movement control, education and promotion, volunteer participation and development of prevention and control technology and materials.

Correct prevention and control, quick effect and national epidemic prevention get twice the result with half the effort.

According to Lin Zongqi, chief executive of the National Red Fire Ant Control Center, there are currently two kinds of red fire ant pesticides approved by the government. One is a poisonous bait, such as Zinuoshi and Indek, with a low dose. In the past, it has been sent to agricultural drug toxicology tests. It is about 1/1000 to 1/10000 of the general dose. After the ants have eaten it, they will die within 5 days in principle.

The other is the continuous application of insect growth regulator baits, such as Priprifen, which will not kill ants when eaten, but will be poisoned and then transmitted to other larvae, making use of the habit of insect peeling to let the whole nest of red fire ants die slowly. On average, only spraying 2 million kilograms of bait per hectare can destroy the entire nest in about a month. Although this method does not meet the needs of the outside world for immediate effect, it is the least land burden and the most effective way of prevention and control.

In addition, in order to carry out correct prevention and control, members of the public should not, for the sake of quick effect, pour boiling water immediately after spraying bait, which will lead to adverse results, causing red fire ants to spread and cause more serious outbreaks.

The Bureau of Prevention and Quarantine once again called on the epidemic prevention work of invading red fire ants, in addition to the full commitment of epidemic prevention personnel, if the public can have a correct understanding and the concept of self-prevention, pay more attention to the surrounding environment, or even assist in protecting the environment, epidemic prevention work can achieve twice the result with half the effort. In the past 105 years, when Ilan County was invaded by red fire ants, it took one year to extinguish 146 hectares of red fire ants in the whole county because of the early detection of the people and the active investment of the local government.
