Problems solved by technology

[0007] Chemical pesticide baits have only one or two insecticidal ingredients, and the ingredients are single. Long-term use of RIFAs is prone to resistance, and large-scale use of chemical pesticides is likely to produce pesticide residues and pollute the environment.
Rotenone, matrine, keratine, toxaline, veratrine and other plant-derived ant-killing active ingredients have acute poisoning effect on red fire ants or have no obvious control effect

Abstract

The invention relates to the technical field of solenopsis invicta drugs, and particularly relates to a bait-type solenopsis invicta drug. The effective ingredient of the bait is an extract of the complete plant fresh sample of an leguminous tephrosia plant called Tephrosia vogelii, wherein the extract can be one or more of the root extract, stem extract, leave extract, bean pod extract, flower extract or seed extract; the extract can be ethanol extract, acetone extract, chloroform extract or ethyl acetate extract; the mass percentage of the extract is 0.69%-4.25%. The active ingredients of the bait are extracted from natural plants and can be fully degraded in environment after being applied, and residual contamination is avoided; the bait has a slow toxic activity, and solenopsis invicta worker ants can be induced to carry the bait to the anthill, and through mutual trophallaxis between individual solenopsis invicta ants, the toxicant in the bait is delivered to the queen ant and other reproduction ants, therefore, the control effect of killing a whole anthill of solenopsis invicta is achieved.

Description

technical field [0001] The invention relates to a poisonous bait insecticide, in particular to a poisonous bait insecticide for red fire ants. Background technique [0002] The red fire ant (Solenopsis invicta) belongs to the Hymenoptera (Hymenoptera) Formicidae (Formicidae) Leafcutter Ant Subfamily (Myrmicinae) fire ant genus (Solenopsis), native to the Paraná River Basin in South America. In 2003, the first report of RIFA invasion was found in Taiwan, my country. In September 2004, the RIFA epidemic was first discovered in Wuchuan City, Guangdong Province. Guangxi, Hunan, Fujian, Hong Kong, Macao and other places also found RIFA in succession. [0003] RIFA is a social insect, and different types of ants perform different social divisions in one family group. The larvae play an essential role in the food digestion of the ant colony, while the queen and worker ants are the most critical members of the ant colony. The queen ant is the only individual that has the reproduct...
