Abstract
The questions related to the participation of corpora allata in qualitative and quantitative manifestation of photoperiodizm in monovoltine silkworm have been discussed. The characteristics of photoperiodical reaction have been studied: it is determined that qualitative reactions are of intermediate type; quantitative-distinct, but not coordinated with qualitative reactions. It is discovered that resection of corpora allata results in decrease of egg numbers, but does not change the character of the quantitative photoperiodical reaction. Whereas, allatectomy of pupae does not prevent the induction of embryonic diapause, but changes the curve of the qualitative photoperiodical reaction and distracts the dynamics of the quantitative photoperiodical reaction. This indicates the relation between both manifestations of photoperiodizm and it points to the fact that formation of diapause is based on the quantitative reactions.
