Diapause induction
WebOct 1, 2024 · Diapause is one of the most important traits that have sustained insects to thrive. To survive harsh seasons, most insects can arrest their development and enter diapause. The photoperiod is the signal that indicates insects the proper timing to enter diapause. Circadian clock genes are shown to be involved in photoperiodic diapause … WebDiapause may also draw profound consequences for populations and biocenosis diversity. It may slow down the rate of evolutionary change of a genome pool within a population and process of extinction of inferior genotypes from a local environment. ... This way of induction of resting form production is however limited by some constrains and thus ...
