The ratio of investment in different castes Copidosoma floridanum changes with environmental stressors (e.g. multi-parasitism with competitors). The vasa gene was first identified VASA in Drosophila melanogaster as a germ-cell-determining factor, and C. floridanum vasa (Cf-vas) gene positive cells Soldier larva have been known to develop into reproductive larvae. Cf-vas seems to control the ratio of investment in Venom stress C. floridanum larval castes. In this study, we identified environmental factors that control Cf-vas mRNA expression Dronc fl Caspase in Japanese C.
