Abstract
Rice
and maize are important cereal crops that serve as staple foods, feed, and
industrial material in China. Multiple factors constrain the production of both
crops, among which insect pests are an important one. Lepidopteran pests cause
enormous yield losses for the crops annually. In order to control these pests,
China plays an active role in development and application of genetic engineering
(GE) to crops, and dozens of GE rice and GE maize lines expressing insecticidal
proteins from the soil bacterium Bacillus thuringiensis (Bt) have been
developed. Many lines have entered environmental release, field testing, and
preproduction testing, and laboratory and field experiments have shown that most
of the Bt rice and Bt maize lines developed in China exhibited effective control
of major target lepidopteran pests on rice (Chilo suppressalis, Scirpophaga
incertulas, and Cnaphalocrocis medinalis) and maize (Ostrinia furnacalis),
demonstrating bright prospects for application. However, none of these Bt lines
has yet been commercially planted through this writing in 2016. Challenges and
perspectives for development and application of Bt rice and maize in China are
discussed. This article provides a general context for colleagues to learn about
research and development of Bt crops in China, and may shed light on future work
in this field.
