- adj. of an inactive stage in the development of some insects, between the larval and the pupal stages
Ten crude larvae, prepupae and pupae in the late part of the fourth instar stage, the prepupal stage and day seven of the pupal stage were used for the soluble and membrane-bound trehalase activity analysis of individuals for three independent experiments.
Because SeTre-1 was expressed at a higher level in the prepupal stage, whereas
SeTre-1, the expression level of SeTre-2 increased initially followed by a persistent reduction until the prepupal stage, leading to a severe shortage of glucose in the pupal progress, which may cause pupation malformation (
SeTre-1 gene in the prepupal stage was found to be much higher than in other stages (
SeTre-2 dropped significantly in the prepupal stage, leading to a severe shortage of glucose that caused a pupation malformation (
For example, SeTre-2 activity was about two-fold higher than that of SeTre-1 at the late fourth instar stage, while SeTre-1 activity was about three-fold and about 1. 5-fold higher than SeTre-2 in the prepupal stage and late pupal stage, respectively (
