Insects are the dominant animals in the world with more than one million described species. The vast majority of insects are innocuous or beneficial to humans, but a small percentage are pests that require a significant amount of our time, effort and funds to reduce their negative effects on food production and our health and welfare. One environmentally acceptable method to control these insect pests is to use pathogens. The study of pathogens infecting insects is referred to as “insect pathology.” Insect pathology is the study of anything that goes wrong with an insect, and therefore, includes non-pathogenic and pathogenic causes. Our focus is on pathogens that can be used as microbial control agents of insects. Here, the basic principles in insect pathology including the microorganisms that cause diseases, their portal of entry, infectivity, pathogenicity and virulence, course of disease, Koch’s postulates, and diagnosis are covered.
