We are a joint-agency and NGO stakeholder group working in collaboration to coordinate the research, monitoring, management, regulation, and outreach and education related to the Polyphagous and Kuroshio Shothole Borers/Fusarium Dieback complex and other emerging pests of wildland and urban forests.

Word is spreading fast about ISHB, hopefully faster than the beetles themselves. Visit our US News Archive, International News Archive, or ISHB YouTube Channel to see what's being said.

If you would like to speak with someone about Polyphagous shothole borer/Fusarium dieback (PSHB/FD) or Kuroshio shothole borer/Fusarium dieback (KSHB/FD), contact your county Agricultural Commissioner or University of California Cooperative Extension.
