Description
Technical Field
The invention relates to a capturing device and a capturing method for blocking alternation of ampullaria gigas generations.
Background
Pomacea canaliculata of the order gastropoda in the phylum mollusca of the genus Pomacea was introduced in the continental of China in 1981. The snails are wide in feeding property, large in food consumption, strong in adaptability and fast in growth and reproduction, are abused and disaster-causing in most Asian countries, seriously harm aquatic crops such as rice and dry crops near water areas, cause serious yield reduction and even no harvest of the crops, become extremely serious agricultural pests, and are listed as one of foreign invasive species in China at present. In addition, ampullaria gigas is also a host for zoonosis, angiostrongylus cantonensis. When the ampullaria gigas which is not heated fully is eaten, parasites such as angiostrongylus cantonensis and the like can be infected in a human body, meningitis and other diseases can be caused, and serious patients can die.
The ampullaria gigas can cause disasters and is characterized by extremely strong reproductive capacity. The breeding season of the ampullaria gigas is 3-11 months per year, wherein 5-8 months are the breeding season. Each snail lays eggs one by one, and the egg laying amount is 200-1000. Can lay eggs 20-40 times in one year, and the egg laying amount is 3-5 ten thousand grains. 1 female snail co-propagates more than 32.5 million young snails in two generations in 1 year, and the fertility is extremely strong. The reproductive characteristics of Pomacea canaliculata are used to lay eggs at night on the surface of dry objects or plants above the water surface, such as stems, trench walls, ridges and the like.
Currently, the prevention and treatment of ampullaria gigas are mainly as follows: 1. applying molluscicide to kill mollusks. The method has the following defects: the chemical agent has high toxicity, is easy to remain crops and water, and pollutes the environment. 2. A biological control method for duck breeding, fish breeding and the like. The method has the following defects: the mode needs to have certain culture conditions and facilities, and the ducks can cause damage to crop seedlings such as partial treading, pecking and the like. 3. Manually picking snails or removing egg masses. The method has the following defects: the labor cost is high, and the efficiency is low. Chinese patent No. CN200810121170.X discloses a Pomacea canaliculata egg mass trapping device which can trap Pomacea canaliculata to lay eggs in a centralized manner, and trap and treat the egg masses in a centralized manner to kill the Pomacea canaliculata, but cannot trap and kill the Pomacea canaliculata. One oviposition snail can oviposit 20-40 times per year. Moreover, if the egg mass in the device is not removed in time, newly hatched young snails fall into the field and regenerate a generation.
