Abstract:
The
rice striped stem borer, Chilo suppressalis, is one of the most
destructive insect pests affecting rice production in China. Achieving
efficient and environmentally sustainable control of C. suppressalis is,
therefore, critical for ensuring national food security. This pest exhibits
highly asynchronous development, leading to the simultaneous presence of
multiple larval instars and overlapping generations in the field. The
consequent lack of distinct temporal windows for targeted intervention
complicates effective management. Moreover, efforts to develop rice varieties
with high levels of resistance to C. suppressalis have so far been
unsuccessful. Consequently, periodic outbreaks of this pest continue to occur.
This review comprehensively summarizes advances in research, key findings and
research perspectives on C. suppressalis in China since the year 2000.
Emphasis is placed on the impact of rice cultivars, cropping systems, the
evolution of insecticide resistance, the development and implementation of control
technologies, and the population dynamics and damage caused by C.
suppressalis. This review provides valuable insights for developing
sustainable management strategies for C. suppressalis in China.
