Adult ampullaria gigas trapping device suitable for paddy fields

Abstract

The invention belongs to the technical field of ampullaria gigas, and particularly relates to an adult ampullaria gigas trapping device suitable for paddy fields. The adult ampullaria gigas trapping device comprises a bottom plate, wherein an arc-shaped connecting plate is arranged around the surface of the bottom plate, one end of the arc-shaped connecting plate is connected with a trapping shell, the surface of the bottom of the trapping shell is connected with a trapping and killing barrel, a trapping shell inlet is formed in the inner wall of the trapping shell, and the position of the trapping shell inlet is located over the arc-shaped connecting plate. By means of a rotating rod, an L-shaped rotating rod, a temporary standing disc and a salt storage shell, the ampullaria gigas falls into salt water in the trapping and killing barrel, water in the ampullaria gigas can permeate from the body with low salt content to the position with high salt content outside the body, the salt water enables the ampullaria gigas to lose water to die through dehydration, due to the fact that the density of the water is smaller than that of the salt water, the water in the ampullaria gigas is not prone to being fused with the salt water, water can be located on the salt water, when the ampullaria gigas is trapped into the trapping and killing barrel, the water can overflow from an overflow cavity when the water level line exceeds the water outlet, and nutrient substances in the water can feed the rice back.

Description

technical field [0001] The invention belongs to the technical field of apple snails, in particular to an adult apple snail trapping device suitable for paddy fields. Background technique [0002] The apple snail is a mollusc of the family Pitaceae and the genus Pyrex. The appearance of the shell is similar to that of an escargot. It has a spiral shell. The color varies with the environment and the age of the snail. It is shiny and has several thin longitudinal lines. When crawling, the head and The abdomen protrudes, the head has 2 pairs of antennae, the front antennae are short, the rear antennae are long, and there is an eye outside the base of the rear antennae. There is a thick lung straw on the left side of the spiral body. The shell is thick and the shell height is 7 cm. The juvenile shells are thin, the sutures of the shells sink into shallow grooves, and the navel of the shell is deep and wide. Apple snails like to live in fresh water with fresh water and sufficient ...

AI Technical Summary

Problems solved by technology

The invention provides a trapping device for adult apple snails suitable for rice fields, which solves the problem that apple snails bite rice and other agricultural plants, resulting in reduced production and easily destroying local wetland ecosystems and agricultural ecosystems. It eats very rough plants, and can also scrape algae, and its excrement can pollute the water body
