最大福寿螺图片(福寿螺图片与田螺区别)

猜猜这是什么动物?粉色诱人的螺卵,没错,它就是福寿螺—农作物杀手。前段时间,我回乡下时发现我们那农田、农田水沟里、河流、小溪等到处爬满了这玩意儿,我当时很纳闷福寿螺怎么入侵到我们这里来了?因为这玩意儿导致我们田间、河沟、溪流里的本地螺丝都不见踪影了。我拿着老式的渔网去河沟里看看能否捞到一些小龙虾,发现连小龙虾都少有,全是一些福寿螺。路过的村民看到我桶里的福寿螺都劝我不要吃这玩意儿,说这个东西吃了得病,秧苗都被它给祸害!后来我用手机一查,一查不得了,原来这玩意儿叫福寿螺。

福寿螺,在1981年的时候,福寿螺由巴西籍华人作为高蛋白食物,引入我国广东中山市养殖,到1984年的时候,福寿螺又作为特种养殖对象在广东省推广养殖,由于个头较传统的田螺大很多,螺肉也多很多,不少人觉得它很有养殖前途,因而很快就被人工引种到了广西、福建、四川、云南、浙江、湖北、湖南、江西等地进行养殖。

然而06年北京的一场大规模的寄生虫传染事件,导致160多人在这次事件中感染了“广州管圆线虫”,从此福寿螺在餐桌上”谈之色变“。因此,记得千万别贪口腹之欲去吃这玩意儿,它危险性大着呢!因为福寿螺是一种人畜共患寄生虫病的中间宿主,其体内有很多的寄生虫,每只福寿螺内可含广州管圆线幼虫3000条~6000条,如果生吃螺肉或者食用未煮熟的螺肉,极易引起广州管圆线虫病,而且即使煮熟以后也不可以保证寄生虫完全被杀掉。

福寿螺的危害及防治方法

每年的4月到6月,以及8月到10月是福寿螺产卵和孵化的高峰期,而这2个时期,分别是水稻及其他水生农作物的生长期和收获期,所以希望大家在这期间一定要注意,若是见到农田里或者农渠里有粉色的卵(如图所示),请及时除掉,不然后果还是很严重的。因为福寿螺繁殖和生长极快,一个粉色的卵就能孵出600个福寿螺,1个月左右的时间就能长大,从而会泛滥成灾祸害农作物。

为福寿螺入侵农田残害水稻一事,我向当地的农村农业局工作人员咨询过“怎么灭掉这玩意儿”,他们回答说多养一些鸭鹅,让他们去吃福寿螺,这样就减少了福寿螺数量,我对此深表疑惑,鸭鹅在农村里也很少有人养了,即使有养的,放养鸭鹅的同时,鸭鹅也会吃秧苗啊,这完全不现实,能不能有可靠的办法?他们又给出了一个方案,“买灭螺药剂,如灭螺胺可以消灭福寿螺”。你们觉得怎样灭螺最好?请在下方留言探讨。
