| Abstract/Contents: | "Golf courses are a potential market for microbial insecticides, but how intensive management of such sites interacts with efficacy of entomopathogens is poorly known. University of Kentucky scientists evaluated Agrotis ipsilon nucleopolyhedrovirus (AgipMNPV) for suppressing black cutworms (Agrotis ipsilon Hufnagel) in turf representative of golf course habitats and on whole tees under actual play. Results include: In independent trials on sand- or soil-based putting greens and surrounds or fairway-height creeping bentgrass, less than 1 week-old AgipMNPV residues [10 X 108 occlusion bodies (OBs) per m2] typically resulted in 50-60% lethal infection of introduced third-instars. In most cases, however, there was no residual control beyond 24 weeks. Spraying fairway-height bentgrass with AgipMNPV alone (10 X 109 OBs per m2) gave 90, 85, and 7% infection of second-instars introduced 4 days, 3 weeks, or 5 weeks later, respectively, but adjuvants (optical brightener, lignin, or both) intended to synergize and protect the virus from UV degradation did not extend infectivity. Fresh (less than 1 week) AgipMNPV residues killed 76-86% of neonates hatching from eggs on tees under play, but levels of control plummeted within a few weeks. Three species of braconids, an encyrtid Copidosoma bakeri (Howard), and a tachinid, Bonnetia comta (Fallen) collectively killed 24-31% of larvae recovered from those tees. AgipMNPV seems better suited for targeted control of early instars than for season-long control of black cutworms. Golf turf is a severe environment for baculoviruses, so several applications per growing season would likely be needed to effectively control caterpillar pests." |
