Emphasis is on pathogens and symbionts of invertebrates, predominantly focusing on interactions between microbes and insect hosts, many of which are invasive species. Subjects covered are broad, ranging from population biology, immune responses, basic biologies of pathogens, interactions between hosts and pathogens and epizootiology to use of microbes for control of insect pests.

research overview
- Emphasis in the Hajek program is on pathogens and symbionts of invertebrates, predominantly focusing on interactions between these microbes and their arthropod hosts. Subjects covered are broad, ranging from studies at molecular, cellular, organismal and population levels. Dr. Hajek has worked extensively with a fungal pathogen first seen in North America in 1989 which has been providing natural control of gypsy moth, a major invasive pest of northeastern North American forests, for over 100 years. While this Japanese pathogen does not always provide complete control everywhere, it has been maintaining gypsy moth populations in central New York long-term plots at low densities since it was first reported in North America. Present studies are focusing on spatial and temporal variability in activity of this pathogen and the reasons behind lower infection levels in some locations. Among our other studies of this system, host specificity studies in the laboratory and field have shown that this pathogen provides an excellent example of successful biological control without non-target effects. We have also studied the basic biology and population biology of this fungus as well as spore dormancy, the latter toward potential development of this fungus as a biological control product. Our studies with invasive Asian longhorned beetles have been directed toward use of an entomopathogenic fungus for control of this species introduced from China. We have been developing a novel application method that provides a means for applying insect pathogenic fungi that remain viable for several months, something previously unheard of. Recent studies have demonstrated that beetles exposed to the entomopathogenic fungus can vector fungal spores to infect other beetles. A newer project in the laboratory involves studies of fungal symbionts and a parasitic nematode associated with the invasive woodwasp Sirex noctilio, first collected from North America in New York State in 2004. We have determined that there is less fidelity regarding fungal symbionts among Sirex species, both native and invasive, than previously assumed. The parasitic nematodes used extensively for biological control in the Southern Hemisphere should survive well in the northeastern US but studies of potential non-target impacts are continuing. Additional studies in the lab are diverse and are reflected by publications. Throughout research in the Hajek lab, we strive to learn new information about insect pathogens and symbionts and their relations to insect hosts while answering basic and conceptual questions about the ecology and evolution of infectious disease.

Teaching
teaching overview
- I teach an interactive graduate course in invertebrate pathology, including laboratories in which we use a diversity of techniques, conduct experiments and look at invertebrates infected with a diversity of pathogens and nematodes. I also co-teach a course on biological control and invasives species directed toward non-majors. In this interactive course we address basic principles as well as issues of popular interest. Entomology 277 Invasive Species & Natural Enemies – co-taught every year. Lead responsibility during odd springs (taught every other year 1997-2005 and then yearly from 2005) [previously named Natural Enemies]. Entomology 463 Invertebrate Pathology – taught even springs since 1996 but in 2008, taught during fall. Entomology 477 Biological Control – co-taught with Jan Nyrop in fall 2003. Entomology 670 Seminar in Biological Control -- taught even falls, 2002-2007. Entomology 767 Current Topics in Entomology S05, F07 (half). Guest lecturer in Entomology 201, Alien Empire S07. Guest lecturer in Entomology 241, Applied Entomology Every spring 2000-2007. Guest lecturer in Entomology 444, Integrated Pest Mgmt Nov. 2007. Guest lecturer in SNES 200, Colloquium Series on Invasive Species Nov. 2006. Guest lecturer on Biological Control, University of Helsinki. Finland. 2003. Latin American course on Microbial Control of Insects. Castelar, Argentina (I presented two full days on fungal pathogens) 1997.
