  1. ISSUES HOW DO …REPEATED FIELD MEASUREMETS MOTH SPECIES …WHICH SPECIES (1, ALL?) RESPOND TO …’FIRST’ FLIGHT CLIMATE ? …TEMPERATURE VS PHOTOPERIOD

  2. TOOLS/SUBJECTS HOW DO …uv LIGHT TRAP(S) MOTH SPECIES …COMMON SPRING FLIERS RESPOND TO …CONVERT JULIAN DATE TO PHYSIOLOGICAL TIME CLIMATE ? …INTRA- & INTERANNUAL PATTERNS

  3. SLOW FAST

  4. FAST SLOW

  5. MEAN DAILY TEMPERATURE THIGH + TLOW = TAVEN 2 DAY-DEGREES (HEAT-UNITS) TAVEN - DTH = DDN ACCUMULATED DAY-DEGREES DDN + DDN+1…= EDDN EASY SET UP WITH AN EXCEL SPREADSHEET

  6. COL 1 COL2 COL3 COL4 COL5 COL6 2010 JULIAN HIGH LOW DAILY ACCUM DATE TEMP TEMP DTH DEGD DD . . 83.3 159 68 45 43 13.5 96.8 160 63 44 43 10.5 107.3 161 48 36 43 0 107.3 . . (68 + 45) / 2 = 56.5 . 56.5 – 43 = 13.5 . 83.3 + 13.5 = 96.8

  7. WHICH IS THE WARMER YEAR? 2010 2011 JULIAN ACCUM ACCUM DATE DD DD . . . 159 96.8 79.1 160 107.3 82.0 161 107.3 89.6 . . . . . . 220 250.4 291.2 221 275.6 311.9

  8. year 1 = 1994; year 13 = 2006accum heat units > Dth 9C, Jan 1-June 30.Note: lots ‘o variance basically no trend because 1999 and 2005 was cold everywhere

  9. THE MEAN (“TYPICAL”) NUMBER OF HEAT UNITS ACCUMULATED IN ONE SEASON, Dth > 9C, Jan 1 – June 30.Notes: RANGE AND VARIANCE ARE KNOWN BUT NOT SHOWN; ELEVATIONAL GRADIENT, REDRAW WITH ELEV ON X-AXIS

  10. ACCUMULATION OF HEAT-UNITS Dth > 9C, Jan 1 – June 30.grape = 2004; boysenberry = 2005; lemon = 2006. 2006 slow start fast finish to show the warmest spring accumulation. 2005 the coolest spring, slow start, stayed low. Moth flight reflects these data, examples TBA????
