新疆抗虫棉区域棉铃虫庇护所的评估
Evaluation of the Refuge for Cotton Bollworm (Helicoverpa armigera) in Xinjiang
摘要
Abstract
Objective] Transgenic cotton expressing Bacillus thuringiensis ( Bt) toxins has been widely cultivated for a long period of time,therefore,there is the potential problem for cotton bollworm Helicoverpa ar_migera,to develop resistance to transgenic Bt cotton.Refuge was considered as an effective management for re_sistance control in China,maize as an important agent acting that role.So,the project aims to explore the func_tion of maize through comparison of the difference about crops structure and agriculture system between recla_mation and corresponding areas in Xinjiang.[Method]The changes of planting area of maize which had been considered as the main host used as refuge were evaluated in different areas (Northern Xinjiang,Southern Xin_jiang,reclamation and corresponding areas) by two —way ANOVA based on date 2002 —2012.[Result] Re_sults showed that there had no significant differences existing in Northern and Southern Xinjiang (P ﹥0.05 ), but a crucial difference with the onset of planting maize appeared in reclamation and corresponding areas (P ﹤0.01 ).[Conclusion]It is remarkably important to consider planting scale,distributed space of maize,biologi_cal characteristics of cotton bollworm and sensitive cotton bollworm before chosing feasible germplasm and rea_ sonable planting model of maize which might contribute to diluting and delaying the resistance by cotton boll_ worm,above all,this basic research would be likely to provide a solid evidence for the sustainable development of resistance on transgenic Bt cotton in Xinjiang Region.关键词
