| Outline of Final Research Achievements |
To understand the brain function in lepidopteran insects, the silkworm mutants for the brain responses to environment or situation are invaluable genetic resources. In this project, strain "u80", which shows abnormal oviposition behavior without copulation, the mutant "Fl", which makes malformed cocoons because of abnormal spinning behavior, and the variant "Lm(e)", which shows photoperiodism in larval stages for diapause properties in the next generation, were utilized for genetic analyses, i.e. trials for positional clonings. As the results, the responsible regions for u80, Fl, and Lm(e) were localized on limited regions on chromosomes 10, 7, and 1, respectively.
