摘要： Peanut is one of the widely cultivated oil-bearing and nut crops worldwide, so its stable production is crucial for oil supply and nuts, as well as socioeconomic development. Noctuid pests, such as Helicoverpa armigera (H & uuml;bner) and Agrotis ipsilon (Hufnagel), are the major pests in peanut. With growing resistance to chemical pesticides, there is an urgent need for advanced biocontrol solutions for peanut productions. We evaluated the control effect of Bioattract (R), combined with the insecticide Coragen, a 'mixed food attractant', on noctuid pests through large-scale applications in four main peanut-producing provinces, Henan, Hebei, Shandong and Liaoning, of China from 2019 to 2023 in succession. The main types of insects attracted and killed by the mixed food attractant were noctuid pests, of which H. armigera, A. ipsilon and other pests were 84.2%, 10.4% and 5.4%, respectively. The female/male ratio of H. armigera was 1.04. In the mixed food attractant treatment fields, the average adjusted decrease rates of H. armigera were 68.74% +/- 1.43% for the eggs and 66.84% +/- 1.59% for the larvae; meanwhile, those of A. ipsilon were 59.24% +/- 1.56% for the eggs and 51.06% +/- 1.89% for the larvae. In addition, the damage rate of the new leaves of the peanut plants in the mixed food attractant treatment fields was significantly lower than that in the control fields, with an adjusted declined rate of 78.26% +/- 0.80%. Compared with using conventional chemicals, applying biological food attractants could reduce costs by USD 43.85 +/- 1.14 per hectare. These findings provide a basis for the large-scale promotion and application of Bioattract (R) for peanut pest management.
