Effects of cultivation of genetically modified Bt maize on epigeic arthropods (Araneae; Carabidae)

摘要: Abstract A field study was conducted in Germany to determine the possible effects of transgenic maize cultivation on nontarget epigeic predator organisms. During growing period 2001–2003, activity abundances spiders and carabid beetles were recorded compared three treatments: (1) Bt-maize (Mon 810) expressing Cry1ab protein from Bacillus thuringiensis (Berliner), (2) an isogenic variety, (3) variety treated with insecticide. All treatments replicated eight plots. The results evaluated using different methods. single species statistically analyzed by confidence interval In addition, phenological behaviors spider beetle determined, multivariate statistical evaluation community principal component analysis conducted. Significantly Bt plots control observed both for carabi...
