The Fuchsia snail is an invasive species because it carries a large number of parasites, becomes a carrier of diseases and parasites, is resistant to drugs, and reproduces quickly.

After large-scale reproduction, it competes with the surrounding organisms for sunlight, water, growing space, etc., destroying the growing environment of local species and threatening biodiversity. In addition, the massive reproduction of the Fukushu snail will lead to eutrophication and water quality deterioration, coupled with its own devouring and infringement of aquatic plants that can purify water, to improve the water ecological environment is very unfavorable.

In the reproductive period of rice, Fukushu snail will eat rice seedlings, seedlings, etc., resulting in small seedlings, less effective spikes, thus affecting the grain yield. Forsythia snail has a mixed diet, preferring to nibble on plant leaves, etc., some areas of aquatic crops, such as lotus root, etc. by Forsythia snail nibbling, stem and leaves withered and shriveled, the victim is particularly serious yield reduction rate of more than 50%.

Morphological Characteristics of the Fukushou snail

The Fukushou snail has a spiral shell, the color varies according to the environment and the age of the snail, with a glossy and a number of fine longitudinal stripes, the head and the gastropods stick out when crawling. The head has two pairs of antennae, the anterior antennae are short, the posterior antennae are long, and the bases of the posterior antennae each have an eye on the outside. The left side of the body of the snail has a thick lung suction tube, the adult shell is thick, the shell height is 7cm, the shell of the juvenile shell is thin, the suture line of the shell is sunken in a shallow groove, the umbilicus of the shell is deep and wide.

Shell monoecious, heterozygous mating. Eggs round, 2mm in diameter, the first spawning eggs pink to bright red, the surface of the egg has a layer of inconspicuous white powdery material, in the temperature conditions in May to June, 5 days after the change to grayish white to brown, when the egg has been dissolved into a juvenile snail. Eggs are laid at night on the surface of dry objects or plants above the water surface, such as stalks, ditch walls, walls, ridges, weeds, etc., and the first hatching young snails fall into the water and devour plankton and so on.
