This is a basic information page about Pest alert.
A more in depth version is available at: http://pestalert.applesnail.net/

The advancing invasion of several Pomacea species and the damage that these snails can cause to the food production (mainly rice), makes it more and more important to focus on good pest management. Delivering adequate information about apple snails, and improving knowledge about pest management is essential to control this growing threat.

Request for pest management information

If anyone has good suggestions about golden apple snails pest management, please Especially suggestions/non published material in the field of natural (botanical) derived pesticides and vector (parasite) based methods are very welcome.

Detailed alert information about the golden snail pest

• Interactive view of the spreading of Pomacea canaliculata in Asia.
  Get a better understanding of the rapidly spreading apple snail pest in Asia with this interactive map.

• Pomacea canaliculata is spreading rapidly accross Asia during the last decades and is now on the verge of entering India.
  The results of such an invasion into rice fields can be devastating for the food production. Therefore it's very important to be alert in this matter and report any new spreadings. In order to achieve this, an 'alert poster' has been produced to alert farmers and other people involved in the rice production and trade.
  You can find this poster below. You are encouraged to spread this poster in any form.

• The fire ant as biological control agent?
  Can the fire ant be use as a biological method to control Pomacea canaliculata populations in the Asian rice fields? The observation that the fire ant Solenopsis geminata predates on the eggs of the apple snail Pomacea canaliculata suggest a possible use of this ant as a biological agent. However, cautions should be taken in this approach as the fire ant can become a pest itself.

• Long-horned grasshoppers (Conocephalous longipennis) eat golden kuhol eggs
  The long-horned grasshopper (Conocephalous longipennis de Haan), locally known as tipaklong na mahaba ang sungot, is reported to predate on the eggs of the golden kuhol snail. The news article recommends that rice farmers should be informed on the importance of conserving egg predators such as the long-horned grasshoppers.
