单、双价转基因抗虫棉对棉铃虫适合度及其抗药性的影响
Effects of Univalent Transgenic Cotton CCRI 41 and Bivalent Transgenic Cotton CCRI 44 on Fitness and Resistance to Cry1Ac of Helicoverpa armigera
摘要
Abstract
The Helicoverpa armigera populations AYBC, AYBT and AYCK were fed 16 generations by transgenic cotton CCRI 41, CCRI44 and non-transgenic cotton CCRI 49, respectively. After 26 generations of selection, compared with the control population AYCK, the larval development periods of the AYBC and AYBT populations delayed; pupal weight, fecundity and egg hatching rate reduced. Compared with the AYBT population, the larval development period of AYBC population delayed, fecundity reduced. During 17th-26th generations, the resistance ratios to Cry1Ac for each generation had no difference between AYBC and AYBT populations. And with generation increasing, the resistance ratios to Cry1Ac in AYBC and AYBT populations also increased.关键词
