international scientific advisory sialT to partic- 

 ipate in and oversee tiie selection, screening, 

 and introduction ol' an insect predator commu- 

 nity that will provide a long-lasting biological 

 control mechanism for loosestrife, and which 

 will also develop a corresponding program of 

 research and evaluation. 



Puiple loosestrife is now a naturalized weed 

 that always will he a part of most North 

 American wetlands. Researchers hope that 

 introducing select insects will result in replac- 

 ing monotypic stands of loosestrife by native 

 vegetation and an overall decrease in the occur- 

 rence of the plant. We predict a reduction of 

 puiple loosestrife abundance o\er the next \5- 

 20 years to about 10% of its current level over 

 about 90% of its North American range 

 (Maleckiet al. 1993).
