Problems solved by technology

Chemical control is currently the main method of RIFA control. Its killing speed is fast, and it has achieved remarkable results in the control of RIFA. However, long-term use of chemical pesticides in large quantities will cause damage to non-target organisms. Water sources are polluted to varying degrees
However, there is no relevant research report on the killing of red imported imported fire ants by bitterwood picrin compounds

Embodiment 1

[0042] Extraction, Isolation and Structure Identification of Bitterinoids from Tongkat Ali

[0043] Tongkat Ali root 10kg, pulverized into coarse powder, extracted by cold soaking with 95% ethanol, combined extracts, concentrated under reduced pressure to obtain 270g of total extract. Suspend the total extract with water, extract sequentially with petroleum ether, ethyl acetate, and n-butanol, and recover the solvent under reduced pressure respectively to obtain petroleum ether fraction (40g), ethyl acetate fraction (99g), and n-butanol fraction (85g) and water fractions (26g).

[0044] The fractions of petroleum ether were subjected to silica gel column chromatography, chloroform-methanol system gradient elution (100:0-0:100, v / v), combined by TLC analysis, and 7 main fractions (Fr.a-Fr.g) were obtained .

[0045] Fr.c was subjected to ODS column chromatography, methanol-water gradient elution (20:80-100:0, v / v), combined by TLC analysis to obtain Fr.c1-Fr.c4. Among them, ...

Abstract

The invention discloses an application of picrasma quassioides bitter principle compounds in ant killing, and belongs to the field of ant killing medicaments. The picrasma quassioides bitter principlecompound disclosed by the invention can be applied to killing solenopsis invicta, and after being prepared into the ant killing bait, the picrasma quassioides bitter principle compound has better stomach toxicity activity on invasive pest solenopsis invicta, can effectively kill the solenopsis invicta, is more convenient to use and is not easily interfered and influenced by the external environment. The picrasma quassioides bitter principle compound is obtained by separating and purifying natural plants, and has low toxicity, no residue and no pollution to various commercial crops such as grains, melons and fruits, vegetables and the like. Therefore, the compound has a good application prospect in killing solenopsis invicta pests.

Description

technical field [0001] The invention belongs to the field of ant-killing medicaments, and in particular relates to the application of a bitterwood compound in ant killing, and specifically provides a plant-sourced bitterwood compound ant-killing bait and a preparation method thereof. Background technique [0002] The red fire ant (Solenopsis invicta) is an invasive pest that causes serious harm to human and animal health, agricultural and forestry production, public facilities and the ecological environment. It is listed as one of the 100 most destructive pests in the world, so eradicating it Ants are a daunting technical problem that must be solved for human beings. Chemical control is currently the main method of RIFA control. Its killing speed is fast, and it has achieved remarkable results in the control of RIFA. Water sources are polluted to varying degrees. With the gradual improvement of human awareness of environmental safety, there is an urgent need for low-toxici...
