Subject: Update on Australia salvinia weevil release in Texas

The US Department of Agriculture, in collaboration with the Texas Park & Wildlife Department, introduced the Australian salvinia weevil (Cyrtobagous salviniae) into four areas of giant salvinia infestation in Texas on October 10-11, 2001 (see news story 11/07/01). In routine sampling done in early December 2001, weevils were recovered at 3 of the 4 release sites, while two of these showed significant weevil damage. According to USDA researchers, there may be anywhere from 25 to 90 adults still present in the sample squares after two months. However, any progress made since October is still provisional until further observations are made.
