title: Captures of Ostrinia furnacalis (Lepidoptera: Crambidae) With Sex Pheromone Traps in NE China Corn and Soybeans.
abstract: Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae), commonly referred to as the Asian corn borer, is the most important corn pest in Asia. Although capturing males with pheromone traps has recently been the main monitoring tool and suppression technique, the best trap designs remain unclear. Commercially available Delta and funnel traps, along with laboratory-made basin and water traps, and modified Delta traps, were evaluated in corn and soybean fields during 2013-2014 in NE China. The water trap was superior for capturing first-generation O. furnacalis (1.37 times the Delta trap). However, the basin (8.3 ± 3.2 moths/trap/3 d), Delta (7.9 ± 2.5), and funnel traps (7.0 ± 2.3) were more effective than water traps (1.4 ± 0.4) during the second generation. Delta traps gave optimal captures when deployed at ca. 1.57 × the highest corn plants, 1.36× that of average soybean plants, and at the field borders. In Delta traps modified by covering 1/3 of their ends, captures increased by ca. 15.7 and 8.1% in the first and second generations, respectively. After 35 d in the field, pheromone lures were still ca. 50% as attractive as fresh lures, and retained this level of attraction for ca. 25 more days. Increased captures (first and second generation: 90.9 ± 9.5%; 78.3 ± 9.3%) were obtained by adding a lure exposed for 5 d to funnel traps baited with a 35-d lure.
