What conditions are most likely to support the growth of insect pests in interiorscape plants?

The presence of uniform temperature and humidity along with the absence of natural predators creates an ideal environment for the growth of insect pests in interiorscape plants. Insects thrive in stable conditions where temperature and humidity levels do not fluctuate significantly, as this helps maintain their life cycle and encourages reproduction. Without natural predators, which would typically help keep pest populations in check, these insects can proliferate unchecked, leading to infestations.

In contrast, high levels of natural light may benefit plants but do not necessarily foster pest growth. Extreme temperature fluctuations can stress plants and make them less resilient, possibly even discouraging pests. Frequent watering, while it may support plant health, can lead to other issues like mold but does not directly correlate with pest populations like the controlled and favorable conditions described. Therefore, the combination of stable environmental factors and the lack of natural enemies creates the most conducive environment for pests to thrive.
