Sunnyvale - No treatment
- No JB life stages detected in 2016
- Delimitation trapping only beginning May 1, 2017

Reasoning:
- Eradication Project design provides for possiblity of carry over population (can only treat vegetative material per label instructions - this is why multiple year project)
- Negative delimitation trapping for remainder of 2016 season
- A late surviving instar emerged from an area which could not be treated in 2015 due to label restrictions
- 2015 treatments with Merit 2F were made in late June and are not effective against an existing late instar if present
- 2016 Acelepryn treatments made April-May 15 not effective against late instar/pupa but extremely effective for any new instar resulting from any 2016 egg laying
- One detection does not meet the existing SAP's recommendation for an eradication treatment trigger
