Address

CABI, c/o Plant Protection and Soil Conservation Directorate, Rarosi ut 110, H 6800 Hodmezovasarhely, Hungary

Qualifications

Visiting professorship at the Chinese Academy of Agricultural Sciences in Beijing, China, Adjunct professorship at the Szent István University in Godollo, Hungary, PhD ScNat in Entomology, MSc in Biology

I work as a research scientist and advise on Integrated Crop Management issues at CABI's Swiss centre as well as at CABI's laboratories in Hungary and China. My role as a research scientist involves work on biological control and integrated management of agricultural insect pests.


My background is in biology, ecology, behaviour and the study of host ranges and biosafety of insects and entomopathogenic nematodes. I develop, manage and implement collaborative international projects that use biological control as a component of integrated crop management. I also undertake individual or group training programmes in integrated crop management, integrated pest management, agricultural research methods or biological control for international partners including farmers, advisory services, students and post-graduates. I lecture at the Pyongyang Agricultural University, DPR Korea, at the Szent István University in Godollo, Hungary and at the University of Neuchatel, Switzerland. I have supervised many international BSc, MSc and PhD students.


My work also includes the development of technical dossiers, biosafety dossiers for biocontrol agents, training materials, and scientific publications (incl. nature, science). I hold an adjunct professorship at the Szent István University in Godollo, Hungary, and a visiting professorship at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences in Beijing, China.


My role as an integrated crop management advisor is to work with local partners in various developing, transitional and developed countries to facilitate improved agricultural practices. I provide technical support to reduce the use of pesticides and to help farmers implement more sustainable crop management practices. I have advisory and training experience in Central and Eastern Europe, in east Asia (eg. DPR Korea, China and Cambodia) as well as in Africa (eg. Zambia, Tanzania, Rwanda, Kenya). I work as a master trainer and technical support staff for the global Plantwise programme.

Simulation - taking plant health training to the next level

People in developing countries depend on what they can grow and sell so require a lot of plant health knowledge. The CABI-led Plantwise programme delivers plant health advice to farmers. Trained plant doctors diagnose the problems and advise on ways to manage them. Simulations are a new way to deliver...

Research, rearing and collection services on corn rootworms

The western corn rootworm is a destructive pest of maize. Most damage is caused by larvae feeding on the roots, which becomes apparent when plants lodge. Drawing on some 15 years’ experience as a research and development partner on corn rootworms, CABI has become a key service provider for field surveys,...

Using beneficial maize-rhizosphere microbials against western corn rootworm

The western corn rootworm is a major invasive maize pest in North America and Europe. The phase-out of certain pesticides means control options are increasingly limited. New technologies are being researched in collaboration with five French partners. Using field surveys and candidate gene searches through...

Beneficial nematodes to control rootworms in European maize production

The western corn rootworm is a major invasive maize pest in North America and Europe. Control options become more and more limited as problematic pesticides are being phased out. 10 years of joint efforts in research and development by academic, legislative and commercial partners have led to a...
