Embodiment 1

[0024] Embodiment 1: The lethal effect of ethanol aqueous solution immersion on red fire ants

[0025] Get 30 RIFAs of different grades or worm states respectively, put them into plastic bowls coated with Furlong on the edge, mix different concentrations (volume fraction 20%, 30%, 40%, 50%, 60%, 70%) %, 80%) of the ethanol water solution were poured into bowls, submerged the ants and covered with a petri dish of appropriate size to prevent the ethanol water solution from volatilizing. After soaking for 1 hour, take out the red imported fire ants and put them on the filter paper to blot dry the aqueous ethanol solution, then put the red imported imported imported fire ants into a new plastic bowl, put a petri dish in the plastic bowl, and put a 10% mass fraction in the petri dish A 1.5ml centrifuge tube of sucrose aqueous solution was used to observe the death of RIFA after 24h, 48h, and 72h respectively. Among them, the larvae and pupae of worker ants, after soaking the larva...

Embodiment 2

[0028] Embodiment 2: The lethal effect of continuous fumigation on red fire ants after soaking in aqueous ethanol solution

[0029] The RIFA soaking method is as in Example 1. After soaking for an hour, take out the RIFA and put it in a plastic bowl, and put a small ball of cotton in the plastic bowl, add 1 ml of ethanol water solution with the same concentration as soaking on the cotton, and then seal it with plastic wrap. The death of RIFA was observed after 24h, 48h and 72h respectively. Among them, the larvae and pupae of worker ants, after fumigation, the larvae and pupae of winged ants are taken out and placed on a small piece of paper, and put together in a plastic box. Plug it, and then add worker ants in the same colony as the larvae and pupae to identify whether the RIFA larvae and pupae are dead. If they are dead worker ants, they will be removed and discarded. If they are surviving worker ants, they will be moved to a place near a water source. feed. Repeat 5 an...

Embodiment 3

[0032] Embodiment 3: the control effect of ethanol aqueous solution irrigation nest to red fire ants

[0033] Prepare 30% ethanol water solution to perfuse the red imported fire ant nest. Pour the prepared ethanol water solution with a volume fraction of 30% into the nest irrigation barrel, and use a high-pressure injection gun head to penetrate into the ant nest soil for irrigation (the ant nest diameter is less than 0.5m and the irrigation volume is within 10L; the diameter of the ant nest is 0.5~1m) The irrigation volume is 10L ~ 15L; the irrigation volume above 1m is above 15L). A total of 48 nests were filled, of which 24 nests were covered with plastic film of about 2-3 square meters on the ant nest after filling. The center of the film was roughly aligned with the center of the ant nest, and the edge of the film was pressed with bricks. The distance from the edge of the plastic film is about 0.3-0.8 meters; the other 24 nests (the number of ant nests of various sizes i...

Abstract

The invention discloses a method for controlling red fire ants. The method of the invention uses a low-concentration ethanol aqueous solution to perfuse the nest of the red imported fire ants and fumigates the nests of the red imported fire ants by covering them with a plastic film, so that the nest has a good poisonous effect on the red imported imported imported imported fire ants. The ethanol aqueous solution used in the invention is cheap and easy to obtain in actual production, has no pollution to the environment, is drunk by human beings, can be applied to the control of ant pests, and has very broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a method for preventing and controlling red fire ants. Background technique [0002] The red fire ant (Solenopsis invicta Buren) is an important pest that has invaded my country and has been distributed in more than ten provinces in my country, causing serious harm to public health, agricultural production and ecological environment. The use of chemical pesticides to control RIFA is currently the main control method for this pest, but the residual problems of chemical pesticides and the impact on local biodiversity limit the scope of its use, such as organic farming areas, water source protection areas and aquaculture areas Habitats such as these are not suitable for conventional chemical control. Therefore, the development of new environmental protection methods is an important way to solve the above problems. [0003] Alcohol is a processed food product that ...
