Abstract One of the major applications transgenic crops in agriculture are so‐called Bacillus thuringiensis Berliner (Bt) plants, particular Bt maizes, which produce insecticidal Cry proteins that target specific orders, such as Lepidoptera or Coleoptera. We reviewed publications reported on direct toxic effects Bt‐maize and/or current events larvae non‐target butterflies and moths (Lepidoptera). In total, 20 peer‐reviewed were identified, 16 papers contributed laboratory‐based data seven...
The cultivation of genetically modified maize expressing Bt proteins against Lepidopteran pests poses a risk for non-target (NT) Lepidoptera, particularly species inhabiting agroecosystems and whose larvae are susceptible to toxins expressed in pollen. Here, laboratory studies were conducted determine the adverse effects larval exposure Cry1F pollen (event TC1507) on host plants two butterfly (Pieris napi, Aglais io) moth (Plutella xylostella, Ematurga atomaria). All NT Lepidoptera tested...
Abstract Adult males of the hunting spider Pisaura mirabilis wrap up prey with silk and pass these nuptial gifts to females prior copulation. The digest gifts, including silk, during mating. Laboratory experiments were carried out determine amount P. invest in its possible role sexual reproduction. was always small, indicating that gift has little nutritional value for females. Males had more time produced a larger silk. Starved required than satiated produce given A male body size positive...
Abstract Concerns have been raised that Bt maize pollen may adverse effects on non‐target organisms; consequently, there is a general call for risk assessment evaluating lethal and sublethal side effects. Spiders play an important economic ecological role as pest predators in various crops, including maize. Web‐building spiders, especially, be exposed to the Cry1Ab toxin of by ingestion via ‘recycling’ pollen‐dusted webs intentional feeding. In this study, potential exposure orb‐web spiders...
Petri dish experiments were conducted to study various aspects of prey selection in the predatory carabid Poecilus cupreus . The potential influence active and passive selection, relative frequencies hunger state beetle investigated with respect predation aphids. For focus was on aphid Rhopalosiphum padi , fruit fly Drosophila melanogaster house cricket Acheta domestica used as for comparison.

A novel combination of enzymatic and nonenzymatic steps in a domino process has been successfully demonstrated. biocatalyzed hyroxylation oxidation phenols (tyrosinase, CHCl3, O2) was linked to Diels–Alder reaction subsequent allylation the intermediary formed bicyclic diketones.
The monitoring of genetically modified organisms (GMOs) after deliberate release is important in order to assess and evaluate possible environmental effects. Concerns have been raised that the transgenic crop, Bt maize, may affect butterflies occurring field margins. Therefore, a was suggested accompanying commercial cultivation maize. In this study, baseline data on butterfly species their abundance maize margins presented together with implications for monitoring. study conducted Bavaria,...
Agricultural intensification is known to lead biotic homogenization by selecting against habitat and resource specialist species, but most studies on this phenomenon have been limited certain parts of the landscape diversity gradient. We aimed reveal relationships between functional traits diurnal Lepidoptera structure along a wide environmental gradient from nature reserves intensive farmland in Baden-Württemberg, SW Germany. Butterflies burnet moths were sampled 1500 m long transects using...
