  1. Turf Insect Pest Survey 2004-2005 K. Umeda and G. Towers University of Arizona Cooperative Extension

  2. Introduction • Phoenix: unique climate, environment • Limited insect pest knowledge • Taxonomy • Generations/season • Timing of emergence/occurrence • Control strategies • Economic thresholds

  3. Regional Reports - PTRI • Pace Turf Research Inst, San Diego • Chafer Beetles (1995-96) • Peak Chafer activity same every year • Peak 1: Mid-June • Peak 2: Late Aug/Early Sep • Hypothesized 2 Peaks = 2 species

  4. Materials and Methods Network of blacklight traps around valley

  18. Collection Results 2004-05All Sites

  19. Field Research 2005Insecticide Timing - Grubs • 2 Field trials established • Insecticide applications made based on site-specific trap numbers • Timings – Single, Split, Multiple • Grubs did not infest test areas

  20. Field Research 2005Insecticide Timing - Grubs • Merit 0.2 + 0.2 • Merit 0.3 • Merit 0.4 • Allectus 0.2 • Allectus 0.25 • Allectus 0.25 + 0.25 • Mach2 2.0 • Dupont Exp 0.25

  21. Summary • Masked chafer appears primary grub • 2,3 individual populations of chafers • Each population active at diff. times, with minimum 2 flights on most courses • Conventional mgmt plans may not fit? • Monitoring = INFO to make decisions

  22. Field Research 2005Insecticides - Pearl Scale • Merit • Allectus • Dupont Exp • Meridian • Application made 5/20/2005 • 5’ x 50’ plots, 3 reps

  23. Field Research 2005Cultivar - Pearl Scale • Common • Princess • Tifway 419 • Celebration • Bullseye • Midiron • Turf transplanted 6/10/05

  24. Future Projects • Continue chafer trapping • Encourage adoption of monitoring • Insecticide timing • Observe pearl scale activity • Pearl scale chemical timing/continuation • Varietal resistance
