Aculops lycopersici Tryon (Acari: eriophyoidea) monitoring, control options and economic relevance in German tomato cultivation
(2024-02-02)The tomato russet mite Aculops lycopersici Tryon (Eriophyoidea) is a damaging pest in commercial tomato production in many countries, including Germany. This mite feeds on the surface cells of leaves, stem and fruit. This ... -
Interactions between endophytic Metarhizium brunneum and oilseed rape plants: effects on plant health and possible mechanisms
(2023-10-18)Fungi of the genus Metarhizium, belonging to the order Hypocreales, are well-known entomopathogens that primarily infect insects. However, recent research has revealed their multifunctional lifestyles, including their ... -
Combined application of a biopesticide and a botanical compound to control fungus gnats Bradysia impatiens
(2021-12-14)Fungus gnats, including the common species Bradysia impatiens Johannsen (Diptera: Sciaridae) are one of the most common pests in greenhouse production systems, mainly due to the direct feeding damage by larvae on the roots ... -
Use of an entomopathogenic, endophytic Metarhizium brunneum isolate (Cb15III) to manage wireworm and Colorado potato beetle
(2019-10-02)Potatoes (Solanum tuberosum, L.) are one of the most important crops worldwide and beside of rice, wheat and maize of an essential importance for the nourishment of the world population. However, potato plants are sensitive ... -
Effects of cropping systems on plant-associated microbial communities of faba bean and wheat
(2019-07-24)Beneficial plant-associated microorganisms are widely acknowledged as key promoter in plant growth and health. Although playing crucial roles in ecosystem functioning and in a sustainable agriculture, our knowledge on the ... -
Interactions between invertebrate and mycotoxin-producing fungi
(2018-12-12)Interactions between fungi and invertebrates nearly occur in every ecosystem. Grazing affects fungal biomass density and is species-dependent. However, how invertebrates affect mycotoxin-producing fungi has not been studied ... -
Occurrence and Importance of Foliar Diseases on Maize (Zea mays L.) in Central Europe
(2018-07-09)In the last decade, the acreage of maize has increased continuously in Central Europe due to its high yield and diverse uses as food, feed and bio-energy. This has led to more intense maize cultivation in many regions with ... -
Productivity, water use and climate resilience of alternative cocoa cultivation systems
(2018-05-23)Global demand for cocoa beans is projected to keep rising while future production is likely to be limited by climate variability and change. Over 70% of the global cocoa supply comes from West Africa, a region expected to ... -
Landscape heterogeneity affects arthropod functional diversity and biological pest control
(2017-12-07)Land-use change is a major cause of biodiversity loss. In agricultural landscapes, which cover 40% of European land, changes in land-use are spatially and temporally very dynamic, thereby changing the organisms’ habitat ... -
A Spatially Explicit Individual-Based Model of the Population Dynamics of the greenhouse whitefly (Trialeurodes vaporariorum), Encarsia formosa and tomato powdery mildew (Oidium neolycopersici) in Tomato Crops.
(2017-07-18)The greenhouse whitefly Trialeurodes vaporariorum – Westwood is one of the most important insect pests in crops. The spatial dynamics and population grow of the insects are affected by different biotic and abiotic factors ... -
How entomopathogenic endophytic fungi modulate plant-insect interactions
(2017-06-07)Tomato plants host multiple microbes able to colonize plant tissues endophytically without causing symptoms of infections. Whether these microorganisms living inside the plants co-exist completely undetected by the plant ... -
Effect of temperature on the interactions between beet cyst nematodes (Heterodera schachtii and Heterodera betae) and sugar beet
(2016-10-28)Climate change is expected to cause a mean annual temperature increase in Germany of 2 °C by 2050 and up to 4 °C by 2100. This is likely to have effects on crop development and pathogen development as well. For this Ph.D. ... -
Exploitation of synergistic effects between semiochemicals and Metarhizium brunneum against soil pests
(2016-08-23)Root-feeding insects, such as the larvae of the western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) and wireworms Agriotes spp. Eschscholtz (Coleoptera: Elateridae), the larvae ... -
Intensification of paddy cultivation in relation to changing agrobiodiversity patterns and social-ecological processes in South India
(2016-07-01)Around the globe, natural and agrarian landscapes are subject to agricultural intensification to meet the increasing and changing demands for resources of the growing population. This intensification takes place at two ... -
Effect of plant traits on host selection and performance of rape stem weevil (Ceutorhynchus napi Gyll.) (Col.: Curculionidae) on resynthesized lines and cultivars of oilseed rape (Brassica napus L.)
(2015-06-25)During its long growing season oilseed rape is attacked by a wide range of insect pests. Infestation by rape stem weevil (Ceutorhynchus napi Gyll.) and cabbage stem weevil (Ceutorhynchus pallidactylus (Marsh.)) can cause ... -
Influence of Grassland Management and Herbivory on Diversity and Ecology of plant-associated Bacterial Communities
(2015-05-29)In the last years, plant-associated bacterial communities caught the attention of investigators due to their importance for both plant health and the environmental balance. Despite the increasing number of studies, there ... -
Effect of climate change on population dynamics and damage potential of insect pests on oilseed rape
(2015-05-21)Biotic stress such as pests can cause high yield losses in agricultural crop systems. It has been estimated that global warming will increase these rates. Thus, the impact of global warming on the distribution and abundance ... -
Landscape context of habitat fragmentation and the diversity of plants, arthropods and snails on calcareous grasslands
(2015-04-10)Land-use change, habitat loss and fragmentation are among the main drivers of the decline of biodiversity worldwide. In Central Europe, calcareous grasslands belong to the most species-rich habitats. They harbour a great ... -
