Infiltration of a Hawaiian 		 Community by Introduced Biological Control Agents,
Science
 









Excerpts: Insects have frequently been
drafted to fight invasive weeds and pests, but these so-called
biological control agents can also attack innocent native species.
Now comes the most detailed example yet of how deeply a control
agent can infiltrate an ecosystem. On page 1314, ecologists report
that parasitic wasps from Texas and China that were introduced
into Hawaii more than 50 years ago to prey on sugarcane pests are
now dominant players in the food web of a remote native
forest.
