PUNCTUREVINE (Tribulus terrestris )
The most successful biological control agents are Microlarinus lareynii, a seed feeding weevil, and Microlarinus lypriformis, a stem boring weevil. M. lareynii and M. lypriformis have been collected from established colonies around the state. Redistribution of M. lareynii and M. lypriformis is available upon request. As part of two beneficial insect exchange programs, these weevils were sent to Oregon and Washington State.
