Rovar growth refers to the developmental process that insects undergo from the embryonic stage to adulthood. Insects exhibit a variety of growth patterns, the most common of which are complete metamorphosis and incomplete metamorphosis. In complete metamorphosis (holometaboly), an insect progresses through four distinct stages: egg, larva, pupa and adult. The larval stage is usually a feeding and growth phase, after which the insect enters a non‑feeding pupal stage where it undergoes extensive reorganization of tissues and organ systems. The adult emerges fully formed, having developed all of the adult structures necessary for reproduction and dispersal.

In incomplete metamorphosis (hemimetaboly), the insect develops through egg, nymph, and adult stages. Nymphs resemble miniature adults, lacking fully formed wings and reproductive organs. Each moulting cycle in insects adds new instars, until the adult stage is reached. The specific number of instars varies among species and is governed by genetic and environmental factors such as temperature, nutrition, and photoperiod.

Hormonal regulation, primarily by juvenile hormone and ecdysone, plays a pivotal role in determining the timing and nature of transitions between developmental stages. Disruptions in hormone balances can lead to altered growth patterns, which are often exploited in pest control strategies. Consequently, understanding rovar growth mechanisms provides insights into insect biology and informs ecological management and agricultural practices.
