Concerns have been raised that transgenic Bt rice may have adverse effects on non-target natural enemies. The spider Hylyphantes graminicola is a generalist predator, and may be exposed to the insecticidal proteins expressed in Bt rice through ingestion of rice pests. Survival, developmental time, body weight and fecundity of the spider did not differ when(More)
T2A-1 is a newly developed transgenic rice that expresses a synthesized cry2Aa gene driven by the maize ubiquitin promoter. T2A-1 exhibits high resistance against lepidopteran pests of rice. The brown planthopper, Nilapavarta lugens (Stål), is a main nontarget sap-sucking insect pest of rice, and Cyrtorhinus lividipennis (Reuter) is the major predator of(More)
T1C-19 is newly developed transgenic rice active against lepidopteran pests, and expresses a synthesized cry1C gene driven by the maize ubiquitin promoter. The brown planthopper, Nilaparvata lugens, is a major non-target pest of rice, and the rove beetle (Paederus fuscipes) is a generalist predator of N. lugens nymphs. As P. fuscipes may be exposed to the(More)
Apterous A (apA), a member of the LIM-homeobox gene family, plays a critical role in the development of wing. The achaete-scute Complex (AS-C) encodes basic helix-loop-helix (bHLH) transcription factors and functions in bristle development. In the present study, we cloned apA (NlapA) and an achaete-scute homologue (NlASH) from N. lugens. Levels of NlapA and(More)
