What are the stages of a complete life cycle?

The stages of a complete life cycle, particularly in the context of insects, consist of four distinct phases: egg, larva, pupa, and adult. This process is often referred to as complete metamorphosis.

In the first stage, the egg is laid, which eventually hatches into the larval stage. During this phase, the immature form is generally voracious and focused on feeding and growing. Following this, the larva undergoes a transformation into the pupa stage, during which it may not appear active as it undergoes significant internal changes to develop into its adult form. Finally, the adult stage emerges from the pupa, fully formed and ready to reproduce, completing the life cycle.

This sequence is fundamental in understanding the development and lifecycle management of various pest species, which can be crucial for effective pest control strategies. Other choices reflect different life cycle mechanisms but do not encompass all stages involved in complete metamorphosis, which is why they are not correct in this context.
