Abstract/Contents:"Scientists at the University of Kentucky continue to explore biological control options for insect pests of golf courses. They evaluated a naturally-occurring baculovirus, Agrotis ipsilon multiple nucleopolyhedrovirus (AgipMNPV), as a potential biological insecticide for black cutworms (Agrotis ipsilon). Because the virus isnt commercially available yet, thousands of already-infected cutworms containing millions of virus particles were ground up, strained, and diluted to make a liquid suspension that was sprayed on the turf. Their findings include: One week after a September application, 50-60% of mid-sized introduced cutworms became lethally infected. In another trial done in summer, 3-day-old virus residues gave 50-60% control on a sand-based putting green and its surrounds, but no residual control after 2 or 4 weeks. Using an optical brightener or lignin, a natural plant pollymer, to the spray mix did not synergize or prolong infectivity of suspension sprays. In trials conducted on whole tees and surrounds at two central Kentucky golf courses, 10-day-old virus residues gave 76% and 82% control of newly-hatched larvae on the two golf courses, but only 41% and 33% cutworm suppression after one month. This suggests that as a biological insecticide, AgipMNPV is better suited for targeted knockdown of small cutworms than for season-long residual control. UK scientists also discovered four species of parasitic wasps and a flies attacking black cutworms that could be useful for biological control."
