This paper provides recommendations on experimental design for early-tier laboratory studies used in risk assessments to evaluate potential adverse impacts of arthropod-resistant genetically engineered (GE) plants non-target arthropods (NTAs). While we rely heavily the currently proteins from Bacillus thuringiensis (Bt) this discussion, concepts apply other arthropod-active proteins. A may exist if newly acquired trait GE plant has effects NTAs when they are exposed protein. Typically,...
Abstract A faunistic study investigating the potential side-effects of corn (Zea mays) genetically modified to express a truncated Cry1Ab protein derived from Bacillus thuringiensis subsp. kurstaki, on non-target arthropods was carried out under field conditions. The communities in soil, leaves and flying crop area were monitored throughout growing season. Water-treated, untransformed served as control, spray application bacterial Bt insecticide (Delfin WG) synthetic (Karate Xpress) used...
SummaryThe potential impact of plant protection products on honey bee brood development is increasing concern. Regulatory authorities therefore now request studies monitoring adverse effects development. Current methods have a number inherent technical limitations which we circumvented by computerization analysis. In this article, describe the computer-assisted digital image analysis and evaluation method in combs. With tool it possible to systematically evaluate basis high definition...
Abstract The impact of the grape leafhopper, Empoasca vitis , on leaf gas exchange, plant growth, yield, fruit quality and carbohydrate reserves grapevines, Vitis vinifera L., was studied. Gas exchange measured discolored (red) green parts infested main leaves from uninfested vines. Photosynthesis mesophyll conductance were severely reduced showing leafhopper feeding symptoms. stomatal red section lower than undamaged control leaves. Additionally, showed transpiration rates when compared to...
The effect of feeding damage by the twospotted spider mite ( Tetranychus urticae KOCH; Acari: Tetranychidae) on gas exchange grapevine leaves Vitis vinifera L.; cv. Pinot noir) was investigated. In addition, influence some pesticides studied. A significant reduction net CO 2 assimilation, transpiration as well stomatal and mesophyll conductance with increasing were observed. At 6000 mite-days per leaf 3rd 9th main (from base) showed an average in assimilation 52.2 % 48.4 %, respectively,...
Abstract A dynamic model for the development of European red mite Panonychus ulmi (Koch) populations is presented and validated with four independent field data sets. It has following characteristics: 1. Mite development, survival reproduction are mainly driven by daily temperature extremes precipitation, modified food supply nitrogen status host. 2. The population cohorts pass through egg, juvenile adult life stages. Their aging occur above stagespecific thresholds modelled distributed...
Agriculture is the dominating land-use in EU member states covering nearly half of surface area. Using herbicides to reduce weed competition agricultural areas can adversely affect Non-Target Terrestrial Plants (NTTP) growing field margins. According EFSA Scientific Opinion on NTTPs an important protection goal maintain biodiversity plant species areas. recommends include also non-crop mentioned OECD guidelines (OECD 208 and 227) testing assess not only vegetative but generative endpoints...
Abstract The influence of temperature and light regime on the feeding intensity Tetranychus urticae (Koch) (Acari: Tetranychidae) was studied bean plants. A nonlinear relationship found between activity T. urticae. increased from 10 °C to 35 °C. At there practically no feeding, whereas at maximum occurred. Above mites decreased. No difference could be in kept permanent darkness or light. Based observed damage symptoms, respectively, we propose use a mite‐load function define mite stress...
