近据夏威夷《Biologic Control of Insect＆ Snail Pests》一文中报道,非洲大蜗牛(Achatina fulica)原在日本孳生繁殖,1936年通过行李邮件等物传入夏威夷的瓦胡岛和毛朋岛,其后扩展蔓延,为害农作物,1938—1951年曾采用各种方法防治,均不奏效,及至1952年开始,从非洲、日本、菲律宾和美国东南部等地引进多种天敌进行防治,其中有12种肉食性蜗牛引进成功。在释放实践中,发现肉食性蜗牛Gonaxisquadrilateralis的效果最好,在许多释放地区已经建立了种群。G.quadrilateralis和G.Kibweziensis对非洲大蜗牛的卵破坏性特别大,且能大量取食1—1.5时的小蜗牛,尤其
According to a report in Hawaii’s “Biologic Control of Insect & Snail Pests,” the original African Achatina fulica breeds in Japan and was imported into Oahu and Maupen Island in Hawaii in 1936 by baggage mail, Spread and harmed crops. Various methods were used to prevent and cure the disease in 1938-1951. All of them failed to work well. By 1952, a variety of natural enemies were introduced and controlled from Africa, Japan, the Philippines and the southeastern United States. Among them, 12 species of carnivorous Snail introduced successfully. In release practice, the predatory effect of the carnivorous snail, Gonaxisquadrilateralis, was found to have been established in many released areas. G.quadrilateralis and G.Kibweziensis eggs are particularly damaging to large African snails and can feed small snails of 1-1.5 in large numbers, especially
