A teacher and student learning how to transplant knapweed into a knapweed insectary bed as food to mass rear knapweed root boring weevils. |
Vials of 100 Larinus minutus each collected by the teachers to take home to help control weeds and jump-start their own programs at their school/county. |
Teachers and students using GPS units to map an insect release site and recording site data. This allows you/others to locate/monitor the release site in the future for success and/or collections. |
Instructor Todd Breitenfeldt explaining how to mass rear knapweed root boring weevils in a knapweed insectary corral. We have to drive 24 miles to Butte to find enough knapweed to transplant into our insectaries because all the closer stands we used to use, are controlled. |
Teachers sweep netting for flea beetles. The Grassrange 2005 collection site (note all the dead leafy spurge) where we collected 1.5 million flea beetles in two partial days. This site is on the edge of a several square mile patch of dead spurge killed by these awesome bio-control insects. |
