Abstract:		"Mating disruption and mass trapping of Ostrinia furnacalis (Genuee), often called the Asian corn borer, were incorporated with insecticides to reduce pesticide use. Pesticides alone are often ineffective owing to problems in timing applications before the larvae enter the protection of corn stalks. In addition, overuse of insecticides has caused environmental contamination and concerns about consumer health. In 2010, 15 insecticides were compared with mating disruption or mass trapping at various dispenser (disp.) densities for reducing egg masses, trap captures, and ear damage. Mass trapping with 30 and 40 disp./ha, mating disruption with 300 disp./ha, or endosulfan, chlorpyrifos, and monosultap (0.55, 0.35, and 0.55 kg/ha, respectively) gave asymptotically equal to50% ear protection. In 2011, an insecticide alone, no treatments, pheromone alone, and pheromone + insecticide were examined. The same insecticides in combination with mating disruption or mass trapping at >==200 or>==20 disp./ha gave >90% ear protection even when chemical applications were reduced to 1 from 3, and the rates were reduced 50-75%. Pheromone dispensers contained >50% of their initial load 30 d after exposure"
