Problems solved by technology

At present, in the comprehensive prevention and control of RIFA, there is no commercial repellent that can quickly and efficiently repel RIFA, mainly because some compounds or materials are too expensive. Compounds that are repellent to RIFA may not be effective long-term as these compounds may be too volatile to be toxic or repellent under field conditions
[0004] In summary, due to the lack of effective RIFA green poisons and repellents, it is not conducive to blocking the spread of RIFA and repelling the occurrence of RIFA in some sensitive areas, such as schools, hospitals and shopping malls, resulting in unnecessary economic loss

Embodiment 1

[0033] Embodiment 1, the application of isoeugenol methyl ether as a poisonous agent for red imported fire ants

[0034] The application of isoeugenol methyl ether poisoning red fire ants provided by the present embodiment specifically includes the following steps:

[0035] The tested insects were wild populations of red fire ants, which were collected near Tianlu Lake Park in Guangzhou (23°14′N, 113°25′E). The nests of RIFAs were collected into plastic boxes coated with talcum powder, and frozen crickets and 20% honey water were used to raise RIFAs.

[0036] In order to determine the application of isoeugenol methyl ether as an RIFA poison, a glass beaker with a diameter of 9 cm was used as a test container, and the inner wall of each beaker was evenly coated with Teflon to prevent the RIFA from escaping. RIFA test concentrations were 0 (control group), 0.005, 0.015, 0.05, 0.15 and 0.5 mg / cm 2 . Spread different concentrations of isoeugenol methyl ether evenly on the botto...

Embodiment 2

[0038] Embodiment 2, the application of isoeugenol methyl ether as a repellant for RIFA foraging

[0039] This embodiment provides the application of isoeugenol methyl ether for repelling red fire ants, which specifically includes the following steps:

[0040] Prepare a square plastic coordinate paper (50×50mm) before the experiment. The concentration of isoeugenol methyl ether is 0.5mg / cm 2Smear it on the square plastic coordinate paper, without adding any chemical reagents. Place a small piece of ham sausage (10×10×1mm) in the center of the graph paper. The coordinate paper coated with isoeugenol methyl ether and the control were randomly placed in the rearing box of the red imported fire ants, and 10 ant nests were used, and each nest was repeated once. 15, 30, 45, 60 minutes Take a high-resolution photo of each coordinate paper with a mobile phone, record the time when the ham sausage was moved out of the coordinate paper, and the last recorded time between the ham saus...

Embodiment 3

[0042] Example 3, the application of isoeugenol methyl ether as a digging repellant for red imported fire ants

[0043] The isoeugenol methyl ether that the present embodiment provides is used for repelling red fire ants, and it comprises the following steps:

[0044] Glue four 2ml sampling vials to the bottom of a petri dish (15 x 1.5 cm), and drill a hole with a diameter of 4 mm in each vial. The sand required for the test was passed through a sieve with a pore size of 0.8 mm, then washed with distilled water, dried in an oven at 80°C for 3 days, and then dried at 50°C for 6 days. Three different concentrations (5, 50 and 500ppm) of isoeugenol methyl ether and a control group were correspondingly set up in each device, and the concentration was calculated based on the weight of the compound and the weight of dry sand.

[0045] Mix 3ml of isoeugenol methyl ether with 30g of dry sand. After the acetone evaporates for 40 minutes, add 1.92ml of distilled water and mix with the ...

Abstract

The invention discloses an agent for killing or repelling solenopsis invicta buren. The agent takes isoeugenol methyl ether as an active ingredient. The solenopsis invicta buren is hymenoptera formicidae myrmicinae solenopsis invicta buren. Tests in the embodiment of the invention prove that isoeugenol methyl ether has a strong repelling effect on solenopsis invicta buren, is often eaten as a spice, is non-toxic to people and livestock, and can be used as an environment-friendly repellent. The agent is green, environment-friendly, simple in component, weak in volatility, long in lasting time, low in cost, capable of being produced in batches and beneficial to repelling solenopsis invicta buren in a large area.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a medicament for killing or repelling red fire ants. Background technique [0002] The red fire ant (Solenopsis invicta Buren) is an agricultural and public health pest native to South America. It has invaded many parts of the world and has caused serious damage to human health, animals, agriculture and forestry on a global scale. The RIFA exhibits aggressive behavior towards humans, and its venom can cause severe infection, fever, anaphylactic shock and, in rare cases, even death. Therefore, finding a highly efficient RIFA poison and repellent is beneficial to reduce the major harm caused by RIFA to agricultural and forestry production and people's physical and mental health. [0003] At present, the control of RIFA is mainly focused on chemical control. Long-term use of highly toxic chemical pesticides will not only increase the resistance of RIFA, but also cause great ha...
