Course description

The analyses of the W chromosome of the silkworm, Bombyx mori and reconsideration of insect behaviors.

Expected Learning

Learning of the structure of retrotransposons. Learning of the behaviors of insects.

Course schedule

The sex chromosomes of the silkworm, Bombyx mori, are designated ZW(XY) for females and ZZ(XX) for males. The W chromosome of B. mori does not recombine with the Z chromosome and autosomes and no genes for morphological characters have been mapped. Femaleness is determined by presence of a single W chromosome, regardless of the number of autosomes or Z chromosomes. It was found that many long terminal repeat(LTR) and non-LTR retrotransposons, retroposons, DNA transposons and their derivatives, have accumulated on the W chromosome as strata. A mutant strain of the silkworm, B. mori was proposed as a model for Parkinson’s disease. Homozygous op mutants exhibiting translucent larval integument are reported to exhibit occasional unique actions such as vibration. However, this occasional unique actions of op/op larvae were simply reactions to touch of other larvae. Adult horned beetles exhibit bark-carving behaviors to feed on tree sap, in part byusing small projections of the clypeus. However, it was shown that adult horned beetles used their mandibles and no the projections of the clypeus to carve bark.
