2. Biology of ABW Feeds mostly on annual bluegrass (Poa annua
Prefers Poa cut at <0.5 in (greens, tees, fairways
Larvae initially feed in leaf blade but eventually move to crown
Pupations occurs below crown in soil
2 generations/yr, sometimes 3

3. ABW Control- 2005
Due to very long oviposition period, many sites required 2 or more preventative pyrethroid applications for good control
Mixed life stages – confused superintendents
Yellow Poa – assumed to be cold related
Common error-premature applications
Curative controls consisted of Merit, Dylox and Dursban, 1-4 applications
Pyrethroid resistance observed (CT) – more treatments will be made

4. White Grubs
Wet, cold spring- JB emergence delayed 12 days – fooled superintendents, fall damage severe
Wettest October on record – pyrethroids gave unusually good curative control of JB
