Subject: Channeled apple snail found in Texas rice fields
Publicada: July 13, 2001

The channeled applesnail, Pomacea canaliculata, was recently detected in rice fields in the vicinity of Houston, TX. It appears that the snails were washed into these fields from nearby waterways as a result of Tropical Storm Allison in June 2001.
P. canaliculata, a major pest of rice throughout Asia and an invasive species in the US, has been known to be well established in Texas, Florida, California and Hawaii for some time, but until recently they had never been found in the rice fields of these states.
As the tropical storm ocurred after the rice had completed its most susceptible growing stages, the crops suffered no damages this year. However, scientists believe that crop damage may become apparent during the next growing period in spring 2002.
The snail also seems to be spreading in Merced Co., CA.
