Agricultural spider decline: long-term trends under constant management conditions.

There is widespread evidence for a worldwide trend of insect decline, but we have much fewer data about recent temporal trends in other arthropod groups, including spiders. Spiders can be hypothesised to similarly decline because of trophic dependence on insects and being equally sensitive to local and global environmental changes. Background trends in arthropod populations can be verified if we decouple large-scale environmental transitions, such as climate change, from local factors.

Studies on the genus Ripersiella Tinsley (Hemiptera: Coccomorpha: Rhizoecidae) in the Neotropical region, with description of a new species.

The Neotropical scale insect genus Ripersiella Tinsley (Hemiptera: Coccomorpha: Rhizoecidae) was investigated, based on soil samples deposited at the Hungarian Natural History Museum. Description and illustration of a new species, Ripersiella incarum Kaydan Szita sp. n.

Consuming alternative prey does not influence the DNA detectability half-life of pest prey in spider gut contents.

Background: Key natural enemy-pest interactions can be mapped in agricultural food webs by analysing predator gut content for the presence of a focal pest species. For this, PCR-based approaches are the most widely used methods providing the incidence of consumption of a focal pest in field sampled predators. To interpret such data the rate of prey DNA decay in the predators' gut, described by DNA detectability half-life ( ), is needed.

Investigations on the Genus Rhizoecus (Hemiptera: Rhizoecidae) with Description of Two New Species from South America.

Neotropical species of the scale insect genus Rhizoecus Künckel d'Herculais (Hemiptera: Coccomorpha: Rhizoecidae) found in soil sample material of the Hungarian Natural History Museum were studied. Two new Rhizoecus species, Rhizoecus kontschani Kaydan and Konczné Benedicty sp. n.

[Setup margin for head-and-neck cancer patients receiving 2D-2D and 3D image-guided intensity-modulated radiation therapy].

Introduction: Image-guided intensity-modulated radiation therapy is essential for oncology treatment of head-and-neck cancer patients.

Aim: MV-kV and CBCT modalities were compared in case of IGRT treatment for head-and-neck cancer patients. Setup error, setup margin (SM), imaging and evaluation times and imaging doses were analyzed.
