Which type of disease cannot be transferred from pest to pest?

Noninfectious diseases are characterized by their inability to be spread from one pest to another, as they are typically caused by environmental factors or nutritional deficiencies rather than pathogens. These diseases can arise from factors such as poor soil conditions, drought, excess moisture, or chemical imbalances.

In contrast, infectious diseases, including viral infections and bacterial blights, are caused by pathogens like viruses and bacteria that can be transmitted between organisms. These infectious agents can spread through various means, such as physical contact, water, or vectors, allowing them to impact multiple individuals within a population.

Understanding the distinction between these types of diseases is crucial for effective pest management, as noninfectious diseases often require different strategies for prevention and control compared to infectious diseases.
