Explanation:

Abiotic factor is a non-living environmental factor like soil, water, temperature, humidity, sunlight, and others. Biotic factor is a living factor including living beings like microbes, humans, insects, and others. A limiting factor is the one which can reduce the abundance and growth of living organisms. A limiting factor can be abiotic or biotic.

Temperature is one of the abiotic factors which can reduce the abundance of pests. Increase in temperature can kill pests, which cannot tolerate the rise in temperature. Animal that feed on pests can also reduce the abundance or population of the pests. Like lizards, frogs, and others.
