What are the key stages in the scale insect life cycle and how do they contribute to the overall population dynamics of these pests?

Scale insects go through several key stages in their life cycle: egg, nymph, and adult. The eggs hatch into nymphs, which then mature into adults. The adults reproduce and lay eggs, continuing the cycle. This contributes to the overall population dynamics of scale insects by allowing for rapid reproduction and population growth, leading to infestations that can harm plants and crops.
