Diapause induction model

WebIndividual insects often exhibit two alternative pathways of non-diapausing and diapausing developments. Yet, most studies have focused on the latitudinal variation in life-history traits for non-diapausing individuals. No study has examined the differences in life history traits between non-diapausing and diapausing individuals along a latitudinal gradient. We used … WebDiapause hormone (DH) is well known for its role in diapause induction in B. mori (see Section 3.12.3.1.1 ), but attempts to induce diapause in other species with DH have failed. Thus, DH appeared to be a neuropeptide with some other primary function that was simply captured by B. mori to serve as a diapause regulator ( Denlinger, 1985 ).
