Long-term and large-scale releases of Trichogramma promote pesticide decrease in maize in northeastern China
Entomologia Generalis 40 (4), 331-335
Abstract: The Asian corn borer, Ostrinia furnacalis, is one of the most important pests of corn crops in Northern China. From 2004 to 2015, a public financial support to biological control of the corn borer resulted in a significant increase in the cultivated area treated with Trichogramma dendrolimi parasitoid applications in corn field in the Jilin Province, in northeastern China. In the present study, we analyzed the impact of these parasitoid releases, from 2000 to 2015 in the Jilin province, on the control of the corn borer as well as on pesticide use. We demonstrated that the widespread large-scale use of T. dendrolimi applications against the Asian corn borer, while being effective for controlling the pest and ensuring competitive corn yields, led to a decrease in insecticide use across the province. The use of Trichogramma is an economically and competitive alternative to insecticide applications in northeastern China.
