Use of Pheromone Timed Insecticide Applications Integrated With Mating Disruption or Mass Trapping Against <I>Ostrinia furnacalis</I> (Lepidoptera: Pyralidae) in Sweet Corn

Abstract

Mating disruption and mass trapping of Ostrinia furnacalis (Génuéé), 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 ≍50% 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.

“…Sex pheromones are an ideal component of integrated pest management programs (Liu and Zhang 2006, Chen and Li 2011, Chen and Klein 2012, Chen et al 2013a, and are a suggested tactic for moth mating disruption when the proper number of dispensers are placed in Þelds , Witzgall et al 2008. Information here correlates positively with previous research.…”

“…This was accomplished by putting 18 dispensers of each type of lure and then removing 3 of them for residue assessment every 5 d from the Þfth to thirtieth day after the exposure. The details on identiÞcation of components were similar to those by Chen et al (2013a). The exceptions were that dispensers were stored at Ϫ22ЊC, and ethyl phenethyl was used as the internal standard for phenethyl propionate, acetone for (R, Z)-5-(I-decenyl) dihydro-2( 3 H)-furanone, phenol for eugenol, and butyl acetate for geraniol.…”

“…Population Dynamics. An automatic water-supplemented pheromone trap (Chen and Klein 2012;Chen et al , 2013) was used to assess male moth activity as a trigger for mass trapping and mating disruption in the three years, to compare moth populations between 2011, 2012, and 2013, and to evaluate the possible carry-over effect of 2011 applications. Nine traps were divided into three groups and placed diagonally in the control plots from 1 May to 30 October during the three years.…”

“…Therefore, there is an urgent need to develop the environmentally friendly methods to control this pest. Among these known modes, such as chemical, biological, or physical pest control, it is an ideal way to control ACB pests by using the sex pheromone mass trapping or mating disruption, because it has the characteristics of being of low cost, environmentally friendly, of low dosage, of strong selectivity, and of high sensitivity [5][6][7][8][9].…”
