摘要：

The long-term effect of Bt-maize on soil animals is an important, repeatedly discussed, but a poorly investigated topic. The collembolan Folsomia candida is a recognised representative of the mesofauna in the laboratory ecotoxicological experiments. The following questions were addressed in the present experiment: (i) is there any consequence on some life-history traits of F. candida, if Bt-maize is provided as food after about 4 years of feeding instead of the near-isogenic counterpart, and (ii) is there any effect on life-history traits, if the near-isogenic and Bt-toxin containing food is changed? Long-term (40-48 generations) feeding on Bt-maize leaf caused alterations in some life-history traits (larger eggs, higher growth rate both in length and width). On the other hand, reproduction (egg size, the total number of eggs, the number of eggs in the first clutch) was influenced, if Bt-toxin containing maize was replaced by its near-isogenic counterpart. Based on currently available methodologies, it is not possible to judge, whether observed differences are due to the Bt-toxin or another component of the maize leaf.
