prepupation
Prepupation is a developmental stage in the life cycle of many holometabolous insects that occurs after the final larval instar and before pupation. During this stage the larva typically stops feeding, becomes quiescent, and may move to a site suitable for pupation. In some groups, the transition to a prepupal form involves a new molt; in others, the larva passes from the last instar directly toward the pupal phase.
Physiological and behavioral changes during prepupation reflect preparation for metamorphosis. Feeding ceases, metabolic processes reorganize, and
Timing and duration of prepupation vary widely among species and are influenced by temperature, humidity, photoperiod,
The concept is important for understanding insect development and ecology, and has practical applications in pest
