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 ... -
Multitrophic interaction of co-inoculated endophyte entomopathogenic fungi
(2022-07-11)The application of entomopathogenic fungi (EPF) as biocontrol agents of insect herbivores is constrained by their limited efficacy due to high sensitivity to UV-light radiation, water leaching, and fungicide application. ... -
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 ... -
Effects of host plants, temperature regimes, and mating scenarios on the population dynamics of the cabbage whitefly Aleyrodes proletella L. (Hemiptera: Aleyrodidae)
(2020-06-03)Within the last decade, the cabbage whitefly has become a major agricultural pest for Brassica crops, which has influenced the agricultural productivity of cabbage (Brassica oleracea convar. capitata L.) Brussels sprouts ... -
Plant virus identification and virus-vector-host interactions
(2019-12-03)The overall aim of this dissertation was the implementation of high-throughput sequencing (HTS) technologies for plant viruses’ identification and characterisation. Different viral enrichment approaches were tested to ... -
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 ... -
Insecticidal properties of the physic nut tree Jatropha curcas L. (Euphorbiaceae) and potential use in pest management
(2019-01-18)The physic nut tree Jatropha curcas L. (Euphorbiaceae) is an oilseed plant widely distributed in tropical and subtropical regions. It is reported as a rich source of phytochemicals and known for its multipurpose use such ... -
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 ... -
Influence of agronomic practices on the development of soil suppression against cyst-forming plant-parasitic nematodes
(2017-05-05)Cyst-forming nematodes are a major group of plant pests of economic importance worldwide. There are well-documented cases of suppressive soils where plant-parasitic nematodes are maintained at very low population densities ... -
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. ... -
