achatina fulica

The giant African snail, Achatina fulica Bowdich, one of the most destructive molluscan pests of many tropical areas of the world, became established in Hawaii November 30, 1936. To control this pest predaceous snails, Gonaxis quadrilateralis (Preston), G. kibweziensis (E. A. Smith), and Euglandina rosea (Ferussac) were introduced. According the Davis, the population of A. Fulica has declined markedly in recent years and numerous empty shells have been observed in many areas of Oahu.
