Method for fabricating ant nest casting mould

Abstract

The invention discloses a method for fabricating ant nest casting mould, which comprises the following steps of: (1) configuring at least one opening at the top end of an ant nest, and configuring an injection tube having the same inner diameter as the opening at the opening; (2) injecting filling material to the ant hill by the injection tube; and (3) when the liquid surface height of the filling material in the injection tube remains unchanged, stopping injection of the filling material and obtaining the ant nest casting mould after the silica gel is cured. The invention solves the problems on high distortion and breakage rate, difficult excavation, storage and transportation, no removal of internal soil and the like in traditional method for fabricating ant nest casting mould by changing filling material constituents and filling methods. Compared with traditional method for fabricating ant nest casting mould, this method has small limitation in location and temperature and low cost, and the fabricated ant nest casting mould is fine and complete and can institutively and really simulate morphological structure and shape of ant nests in the natural world, thereby providing reliable theoretical basis for pest control and scientific research.

Description

technical field [0001] The invention relates to a method for making an ant nest mold, and belongs to the technical fields of pest control and entomology. Background technique [0002] Ants are not only a tool for humans to control pests, but also a pest that humans need to control. It is inseparable from us. Taking the red fire ant Solenopsis invicta Buren as an example, as one of the 100 most dangerous invasive pests in the world, it has serious harm to agricultural and forestry production, human health, public safety and ecological environment. Since its introduction to the United States in the 1930s and 1940s, RIFA has spread rapidly. Currently, the area occupied by the ants in the United States has reached more than 70.129 billion hectares, distributed in 19 states. It is estimated that the economic loss of American buildings and electrical appliances that were first damaged by red fire ants can reach 11.2 million U.S. dollars per year, and the financial loss of Texas a...

Problems solved by technology

Among the three casting techniques currently developed, the gypsum method has the highest mold breakage rate. After the mold is completed, it needs to go through several months of repair and pasting work, and because the gypsum is hard and brittle, most of the fragments cannot be repaired, resulting in Cast finished product distortion

Although the melting zinc and lead melting methods have a slight increase in the drop rate, but due to the limitation of the ambient temperature and location, in most cases the space of the ant nest cannot be filled, and the cost is too high

The common faults of these three methods are: 1. The mold product has a high breakage rate and needs to be repaired and pasted later, resulting in mold distortion. 2. The mold product is too fragile to remove internal soil impurities. 3. The mold material lacks toughness and elasticity. Not easy to dig, transport and store

These three shortcomings hinder the further study of ant nest structure, and also lead to the fact that few domestic researchers conduct in-depth research on ant nest casting.

[0004] Represented by the red imported fire ant, it includes Camponotus socius [Walter R. Tschinkel. The nest architecture of the ant, Camponotus socius. Journal of insect science, 2005, 5: 9.] and Acromyrmex rogosus rogosus [ S.S.Verza et al.Nest architecture of the leaf-cutting ant Acromyrmex rugosus rugosus.Insectes Sociaux, 2007, 54: 303-309.] There is no ideal method for making the ant nest casting molds of various ants
