Evaluation and optimization of the effectiveness of Attracap® and its environmental influences: A biological soil insecticide to control wireworms (Agriotes spp.)
(2024-12-19)The use of entomopathogenic fungi as biocontrol agents in agricultural pest management offers a promising alternative to chemical pesticides, aligning with the increasing global emphasis on sustainable farming practices. ... -
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 ... -
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 ... -
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 ... -
Exploring the interactions of bacterial secondary symbionts (BSS) in wheat aphids, Sitobion avenae F. with parasitoids
(2015-11-20)Bacterial secondary symbionts (BSS) are renowned for their capacity to protect their hosts against natural enemies. Sitobion avenae (F.) is recently reported for Hamiltonella defensa and Regiella insecticola infections. ... -
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 ... -
Colonization pattern of crop plants by endophytic fungi
(2015-06-16)Endophytes are fungi or bacteria occurring inside plant tissues without causing any apparent symptoms in the host plants. Fungal endophytes are quite common in nature; some of them are able to work as bio-control agents ... -
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 ... -
Host-parasite interaction between the potato tuber rot nematode (Ditylenchus destructor), stem nematode (Ditylenchus dipsaci) and potato
(2015-03-18)Nematodes are among important pest constraints influencing potato production worldwide. The tuber rot nematode, Ditylenchus destructor Thorne 1945, and the stem nematode, Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936, ... -
