After a release of genetically modified organisms, monitoring of potential adverse effects on the environment is mandatory. The protocol used for monitoring should be previously tested in practical studies and must be standardised. Moreover, sampling methods and the evaluation of results must meet current scientific and technical standards. Due to...
Butterflies and moths (Lepidoptera) are related to many biotic and abiotic characteristics of the environment, and are widely accepted as relevant protection goals. Adverse effects on butterflies and moths through genetically modified (GM) crops have been demonstrated, by both insect-resistant and herbicidetolerant events. Thus, Lepidoptera are con...
The EU plant protection regulation 1107/2009/EC defines the requirements for active ingredients to be approved, specifically including the assessment of effects on biodiversity and ecosystems. According to that, semi-field methods are expected to be more important in the near future. Therefore, a higher-tier experiment suitable to assess the risk f...
Butterflies and moths (Lepidoptera) have been suggested for the environmental
monitoring of genetically modified (GM) crops due to their suitability as ecological
indicators, and because of the possible adverse impact of the cultivation of current
transgenic crops. The German Association of Engineers (VDI) has developed guidelines for
the standardi...
Terrestrial Model Ecosystems (TME) were developed as one higher-tier option to detect and assess effects of pesticides on soil communities in a 1 year study using lindane (gamma-HCH) as a persistent and toxic reference pesticide. TME contained intact soil cores (diameter 300 mm, height 400 mm) including indigenous soil communities of undisturbed gr...
Perry et al . [[1][1]] developed a model to simulate the field exposure and adverse effects for three European non-target Lepidoptera species ( Inachis io L., Vanessa atalanta L., and Plutella xylostella L.) to pollen of the Bacillus thuringiensis ( Bt ) maize MON810 containing lepidopteran-
Due to their high densities and species diversity as well as their functional role in litter decomposition and as soil-microbial grazers, collembolans are a very important component of the soil biocoenosis. As the compartment "soil" becomes increasingly recognized in environmental protection, they have become a major focus in questions concerning p...
The current scope and contents of the development of VDI Guidelines for the monitoring of the ecological effects of genetically modified organisms are described. The general relevance of standardised VDI Guidelines for a GMO monitoring is explained. In particular, the state of the work of monitoring guidelines for butterflies (Lepidoptera) is descr...
