Problems solved by technology

However, it has the disadvantages of poor poisoning effect and slow action, so it is not suitable for RIFA epidemics that occur in parks, schools, hospitals, stations, tourist attractions, residential quarters, road green belts and other densely populated places with frequent activities

Embodiment 1

[0027] A method for preventing and controlling an epidemic of red imported fire ants, comprising the following steps:

[0028] (1) First find the red imported fire ant nest, and quickly insert it from the top of the nest with a stirring rod, the insertion depth is 8-15cm;

[0029] (2) Immediately after insertion, use the stirring rod to rotate quickly to form a collapsed circle on the top of the ant nest. The size of the collapsed circle depends on the ant nest;

[0030] (3) Immediately pull out the stirring rod, and knock on the surrounding hard objects to knock off the live ants stuck to the stirring rod;

[0031] (4) Put the bait directly into the ant nest, and the amount of bait depends on the size of the ant nest.

[0032] Preferably, the stirring rod is a screwdriver, and the length of the screwdriver is 50cm;

[0033] Preferably, the stirring rod includes a steel bar and a wooden handle, and the steel bar is connected to the wooden handle;

[0034] Preferably, the in...

Embodiment 2

[0040] A method for preventing and controlling an epidemic of red imported fire ants, comprising the following steps:

[0041] 1. First find the RIFA nest, and use a stirring stick to quickly insert it from the top of the nest;

[0042] 2. Immediately after insertion, use the stirring rod to rotate quickly to form a collapsed circle on the top of the ant nest;

[0043] 3. Immediately pour the medicinal solution directly into the ant nest, and at the same time use a stirring rod to insert and pour the medicinal solution until the medicinal solution no longer seeps down, then stop pouring the medicinal solution.

[0044] Preferably, the medicinal liquid in step three is a carbamate insecticide, an organophosphorus insecticide or a pyrethroid pesticide.

[0045] Preferably, the carbamate insecticides are methomyl and carbofuran, the organophosphorus insecticides are phoxim, diazinon, and acephate, and the pyrethroid pesticides are highly effective Cypermethrin, lambda-cyhalothr...

experiment example

[0053] The contact activity of 15 kinds of chemical pesticides on red fire ants was tested indoors.

[0054] The result is:

[0055] Carbamate insecticides: the 24h LC50 of methomyl and carbofuran against red fire ants are 0.03μg / ml and 0.03μg / ml respectively;

[0056] Organophosphorus insecticides: the 24h LC50 of phoxim, diazinon, and acephate against fire ants are 0.05μg / ml, 0.06μg / ml, and 0.09μg / ml, respectively;

[0057] Pyrethroid pesticides: LC50 of beta-cypermethrin, beta-cyhalothrin and bifenthrin against red fire ants were 0.05μg / ml, 0.06μg / ml and 0.06μg / ml respectively.

[0058] Combined with the existing research results, it is considered that RIFA is sensitive to most insecticides. Under the premise of sufficient amount of irrigation liquid, irrigation with contact pesticides can achieve a good control effect on RIFA.

[0059] The prevention and control method of the RIFA epidemic is reasonably designed, has the advantages of good poisoning effect and quick act...

Abstract

The invention discloses a preventing and controlling method for the red-imported-fire-ant epidemic situation. The preventing and controlling method includes the following steps that (1) a red-imported-fire-ant nest is found out, and a stirring bar is rapidly inserted from the top of the ant nest; (2) the stirring bar is rapidly rotated immediately after being inserted, and a collapsed ring is formed at the top of the ant nest; (3) the stirring bar is pulled out immediately and beaten on peripheral hard substances, and live ants stuck on the stirring bar are vibrated off; (4) baits are directly put into the ant nest. The preventing and controlling method for the red-imported-fire-ant epidemic situation has the advantages of being good in poisoning effect and quick in effect and is suitable for the red-imported-fire-ant epidemic situation occurring at the densely-populated-and-frequent-event places, the red-imported-fire-ant epidemic situation can be effectively and rapidly controlled in time, diffusion and extension of red imported fire ants are delayed, the population quantity of red imported fire ants in occurrence areas is decreased, and damage of the red imported fire ants to human health and safety is remarkably reduced; the preventing and controlling method has remarkable economic benefits, ecological benefits and social benefits.

Description

technical field [0001] The invention relates to a method for preventing and controlling an epidemic, in particular to a method for preventing and controlling an epidemic of red imported fire ants. Background technique [0002] Red fire ants have obvious aggressiveness and the ability to sting repeatedly to humans and animals. It affects the health and quality of life of the invaders, has serious impacts on agriculture, livestock, wildlife, and natural ecosystems, and damages electronic equipment in public facilities, resulting in financial losses in communications, medical care, and pest control. Once the ant nest is disturbed, the red fire ants will quickly leave the nest and launch a strong attack behavior. The red fire ant clamps the human skin with its upper jaw, and stings the human body several times continuously with the chela at the end of the abdomen, and releases venom from the poison sac every time it stings. After the human body is stung by the red fire ant, th...
