The department is the unique scientific unit in the country where methods for fast diagnosis and identification of quarantine pests are developed; the etiology and the epidemiology of the causal agents of plant diseases and the biology and the ecology of the quarantine pests and weeds are studied; methods and means of control are elaborated; analysis and valuation of the risk of appearance of new quarantine pests in the Bulgarian region are routine procedures.
Great scientific works were done since the department was established:
A lot of dangerous quarantine diseases and pests were investigated as well as measure systems for struggle that are put into practice.
The optimal levels of fumigation of the under-quarantine seedling and sowing material of fruit and flower plants were established.
Shield-bearer aphids from (Coccoideae) in Bulgaria are studied and new 70 species for the country and 1 new for the world were found. 57 new aphid entomophagues for the country and 2 – in the world were established.
Over 100 plant parasite nematodes were investigated as 3 of them are new for the science.
Ecological systems for pest control of basic agricultural crops were developed.
In recent days in the “Plant Quarantine Department” work 4 scientific researchers including 1 Prof.D.Sc. – phytobacteriologist, 2 Ass.Prof., PhD – entomologist, nematologist, 1 Research Ass. - nematologist, 1 PhD Student - phytobacteriologist and 3 specialists.
Research Interests and Main Activities:
• Phytopathogenic bacteria-taxonomy, identification, phases of the
life cycle, ecology and epidemiology, pathogenesis, seed pathology,
the resistant reaction of plant, control;
• Bacterial diseases of tomato, pepper, soybean, onion, ornamental
plants;
• Quarantine bacteria-detection, identification, pest risk analysis.
Research Interests and Main Activities:
• Distribution, biology, ecology of quarantine species – (Fam. Bruchidae,
Trogoderma sp., Cydia molesta, scale insects - Quadraspidiotus perniciosus,
Pseudaulacaspis pentagona etc.);
• Methods for control;
• IPM in peach orchards;
• Synthetic pheromone traps for monitoring and control with quarantine
species;
• Pest risk analysis.
Scientific interests and research:
• Taxonomy of soil nematodes (order Tylenchida, Dorylaimida);
• Bionomy of plant parasitic nematodes (fam. Heteroderidae);
• Methods of control on nematodes of the genera Heterodera
and Meloidogynae.
