Which of the following is not a favorable condition for pest occurrence?

Low temperatures are typically not conducive to pest occurrence because many pests, including various insects and pathogens, thrive in warmer environments. Cold temperatures can slow down their metabolism, hinder reproduction rates, and may even lead to mortality in more sensitive species. Consequently, pest populations tend to decline when temperatures drop significantly.

In contrast, high moisture, abundant food sources, and optimal breeding conditions all create environments that support and promote pest populations. High moisture levels can facilitate the growth of fungi and create habitats favorable for insects. Abundant food sources provide the necessary nutrition for pests to survive and reproduce, while optimal breeding conditions, including suitable temperatures and humidity, allow pest populations to increase rapidly. Thus, low temperatures stand out as the least favorable condition for pest occurrence.
