Current research on soybean pest management in China

摘要

Pest is one of the important factors affecting soybean yield and quality. Until now, 404 species on soybean have been known based on literature review and a large scale survey. More than 20 key pests occur every year and are causing serious damage. In 3 different ecoregions (Northern ecoregion, Huang-Huai-Hai ecoregion and Central south ecoregion), pests occurrence and damage styles show a variety of regional characteris-tics. Soybean pests occurrence from north to south were shown as follow: from large pests to small pests, from chewing pests to sucking pests, from low reproductive rate and less generation pests to high reproductive rate and more generation pests. Soybean pest man-agement is mainly based on resistant breeding, combining with monitoring, plant quar-antine, cultural, biological, physical, mechanical and chemical controls in China. Although pesticides play an important role in practice, the absence of reasonable use has threatened sustainability of China's soybean production. Soybean integrated pest management is not the only strategy, and it still needs improvement and development, but it's the best alterna-tive for pest control. It can be expected that integrated pest management will remain as the main strategy for soybean pest control in future. Further innovation of green prevention and control technology will also become a focus of future research in view of new pest problems brought about by crop restructuring, agricultural system change and global climate change. Integration of above technologies will reduce the harm of pests and production costs as well as improving soybean production capacity. In this review, research progress of Chinese soybean pest and its management was summarized and some suggestions were provided to adapt for soybean pest management under current situation.
