  1. Part 5 Climate Matching

  2. P. japonica general information • Univoltine- one generation per year • Overwinters typically as a third instar larvae

  3. Frequency of Occurrence (30year)

  4. Frequency of Occurrence (30year) Adult beetles begin to emerge in central NC 3rd week in May (Fleming 1972)

  5. Frequency of Occurrence (30year) Beetles appear in central Virginia in last week of May- first week of June.(Fleming 1972)

  6. Mountainous Eastern TN beetles appear first week of June (Fleming 1972) Frequency of Occurrence (30year) Beetles appear in central Virginia in last week of May- first week of June.(Fleming 1972)

  7. Frequency of Occurrence (30year) Adult beetles begin to emerge in Maryland & Delaware mid June (Fleming 1972)

  8. Frequency of Occurrence (30year) Adult beetles begin to emerge in Southern NJ and Southeastern PA in 3rd week of June (Fleming 1972)

  9. Frequency of Occurrence (30year) Emergence in mountainous regions of NJ and PA 1-2 weeks later (Fleming 1972) Emergence in Southeastern NY, CT, RI and Southern MA in last week of June (Fleming 1972)

  10. Frequency of Occurrence (30year) Emergence begins in Southern NH and VT in first week of July (Fleming 1972)

  11. Frequency of Occurrence (30year)

  12. Frequency of Occurrence (30year)

  13. Chrysanthemum White Rust • Chrysanthemum white rust (Puccinia horiana) • Overwinters when min T > -6oC • Infection requirements Tmin = 4, Topt = 17, Tmax = 23oC, Wmin = 6 h, precipitation > 2 mm per day (Water 1981).

  14. Chrysanthemum White Rust Frequency of years without overwintering

  15. Chrysanthemum white rust Average number of days suitable for infection

  16. Pine Shoot Beetle (PSB), Tomicus piniperda • Overwinters as adult, can emerge as soon as temperatures reach 50-54 F • Emerges over a relatively short period of time • Important to have traps out in time but not too early http://www.ncrs.fs.fed.us/4401/focus/climatology/tomicus/

  17. PSB > 40 F January 1-15 Frequency of Occurrence (30 year) > 45 F > 50 F
