Outline Activities
Outline of research: Main research titles of our laboratory are microbial control of insect pests, characterization of entomopathogenic microorganisms, mechanism of microbial infection in insects, defense reaction of insects against pathogens, and studies of invertebrate cell culture.
I concentrated especially on protozoan infection in insects and studies of lepidopteran insect cell culture as follows:
1) Studies on infection and development of entomopathogenic microsporidians as microbial control agents using insect cell cultures.
2) Development of in vitro germination methods for poor germinators of the microsporidians.
3) Ultrastructursal study of host-microsporidian parasite interactions.
4) Clonig of the microsporidians and chromosomal study of those clones.
5) Study of a protozoan parasite isolated from the West Indian sweet potato weevil.
6) Establishemnt of insect cell lines having a highly phagocytic ability.

Outline of education:
1) Lectures and tutorials of Insct Pathology and Microbial Control for the graduate students.
2) English lectures of Microbiology, Insct Pathology and Microbial Control for the undergraduate and the graduate students in special course on international development research (partial responsibility).
3) Lecture of Insct Pathology and Microbial Control for the undergraduate students (partial responsibility).

    1994.01Title: Studies on biological characteristics of entomopathogenic microsporidians Outline: The microsporidia are obligate intracellular parasites and parasitize a wide range of vertebrate and invertebrate hosts. Focusing in particular on the host insects and parasite interactions, biological characteristics of entomopathogenic microsporidians as microbial control agents are investigated using insect cell cultures..
