The primary factor that affects an insect's ability to thrive in a specific environment encompasses a combination of temperature, moisture, and food supply, which all play critical roles in the life cycle and behavior of insects.

Temperature influences insect metabolism, development rates, and reproductive cycles. Each species has its own temperature range within which it can survive and reproduce. Extremes in temperature can hinder growth or even lead to mortality.

Moisture is essential for most insects, especially those that require specific humidity levels for survival and reproduction. A suitable level of moisture can affect their habitat choice, breeding, and feeding behaviors. Many wood-destroying organisms, for example, prefer damp environments, which can enhance their survival and proliferation.

Food supply is perhaps the most obvious factor, affecting the survival rate and reproductive success of insects. The availability and quality of food directly correlate to an insect's growth, health, and ability to reproduce.

Thus, the thriving of an insect species is determined by the interplay of these factors. The collective influence of temperature, moisture, and food supply illustrates why all of them are critical to the ecology of insects. Indirectly, any changes in one factor can influence the others, impacting the overall environment that an insect inhabits.
