Where invasive, they can utilize crops such as rice and taro as a substrate for reproduction. Plan MR, Saska I, Cagauan AG, Craik DJ"Backbone cyclised peptides from plants show molluscicidal activity against the rice pest Pomacea canaliculata (golden apple snail)." In the Philippines, the word “maya” refers to more than one kind of bird. They damage direct wet-seeded rice and transplanted rice up to 30 days old. You can also use attractants or plants that attract snails, such as papaya and cassava leaves, to make hand picking easier. Using a field survey dataset for the invasive golden apple snail P. canaliculata in China, we examined the ASR, quantified its variation across multiple spatial and temporal scales, and analyzed the potential associations between ASR and abiotic/biotic factors. It is also considered as about the 40th the worst alien species in Europe and the worst alien species of gastropod in Europe. The shell opening (aperture) is large and oval to round. The 5 to 6 whorls are separated by a deep, indented suture (hence the name 'canaliculata' or 'channeled').

Some time later the snails spread to Hawaii, South-West Asia and even Florida. A species of aquatic snail that encompasses the mystery snail, the Golden Inca snail, and many others, the apple snail is an easy addition to any tank. Apple snails have difficulty moving in less than 2 cm of water. Keep fields drained as much as possible during the vulnerable stages of the rice plant (below 30 days) or transplant 25−30 day old seedlings from low density nursery beds. Golden apple snails have muddy brown shell and golden pinkish or orange-yellow flesh. There’s the chestnut munia (Lonchura atricapilla), which is the “true” maya, the real former national bird.

Common Name: Apple Snail (Golden Apple Snail, Channeled Apple Snail) Scientific Name: Pomacea canaliculata Classification: Phylum or Division: Mollusca Class: Gastropoda Order: Mesogastropoda Family: Ampullariidae Identification: Pomacea canaliculata looks very much like congeneric species. [26], Pomacea canaliculata has displaced some of the indigenous rice field apple snail species in the genus Pila traditionally eaten in Southeast Asia (including Thailand and the Philippines) such as Pila ampullacea and Pila pesmei; as well as the viviparid trapdoor snail (Cipangopaludina chinensis). apple snail,” “apple snail,” “jumbo snail,” “golden miracle snail,” or “giant apple snail” (Mochida 1991).
