Predation on within Hedges in the Agricultural Landscape.

The invasive feeds and reproduces on various cultivated and wild fruits and moves between agricultural and semi-natural habitats. Hedges in agricultural landscapes play a vital role in the population development of , but also harbor a diverse community of natural enemies. We investigated predation by repeatedly exposing cohorts of pupae between June and October in dry and humid hedges at five different locations in Switzerland.

Epileptic Activity Increases Cerebral Amino Acid Transport Assessed by 18F-Fluoroethyl-l-Tyrosine Amino Acid PET: A Potential Brain Tumor Mimic.

Unlabelled: O-(2-F-fluoroethyl)-l-tyrosine (F-FET) PET is a well-established method increasingly used for diagnosis, treatment planning, and monitoring in gliomas. Epileptic activity, frequently occurring in glioma patients, can influence MRI findings. Whether seizures also affect F-FET PET imaging is currently unknown.

Lung clearance index and moment ratios at different cut-off values in infant multiple-breath washout measurements.

Background: Multiple-breath washout (MBW) is increasingly used for infant lung function testing. Current guidelines recommend calculating lung clearance index (LCI) and functional residual capacity (FRC) at 2.5% of normalized tracer gas concentration, without clear recommendation for moment ratios (MR).

Multiple breath washout analysis in infants: quality assessment and recommendations for improvement.

Infant multiple breath washout (MBW) testing serves as a primary outcome in clinical studies. However, it is still unknown whether current software algorithms allow between-centre comparisons. In this study of healthy infants, we quantified MBW measurement errors and tried to improve data quality by simply changing software settings.

Continuous exposure to the deterrents -jasmone and methyl jasmonate does not alter the behavioural responses of .

Behavioural responses of (Pergande) (Thysanoptera: Thripidae), a generalist, cell sap-feeding insect species with piercing-sucking mouthparts, after continuous exposure to two deterrent secondary plant compounds are investigated. We compared in choice assays on bean leaf discs, the settling, feeding, and oviposition preferences of females that had no experience with the two fatty acid derivatives methyl jasmonate and -jasmone before testing (naïve thrips) vs. females that had been exposed to the deterrent compounds before testing (experienced thrips).

Systemic above- and belowground cross talk: hormone-based responses triggered by Heterodera schachtii and shoot herbivores in Arabidopsis thaliana.

Above- and belowground plant parts are simultaneously attacked by different pests and pathogens. The host mediates these interactions and physiologically reacts, e.g.

Habituation in to deterrent plant compounds and their blends.

Feeding and oviposition deterrence of three secondary plant compounds and their 1:1 blends to adult female Pergande (Thysanoptera: Thripidae) and the potential for habituation of the thrips to the pure compounds and the 1:1 blends at various concentrations were investigated. In choice assays, we tested dose-dependent feeding and oviposition deterrence of the two fatty acid derivatives methyl jasmonate and -jasmone, the phenylpropanoid allylanisole, and their blends when directly applied to bean leaf discs. The concentration required to reduce the feeding damage by 50% relative to the control treatment (FDC) was lowest for -jasmone and highest for allylanisole.

Behavioural responses of Pergande larvae to methyl jasmonate and -jasmone.

The larval stages of Pergande (Thysanoptera: Thripidae) cause more direct feeding damage to plants than the adults. We, therefore, investigated the behaviour-modifying effects on second instar larvae of two jasmonic acid derivatives. The artificial application of methyl jasmonate and -jasmone, both at 1 % concentration, deterred the larvae from settling in a dual choice bean leaf disc assay.
