Entomology is the scientific study of insects, and the science itself is a specialized area of zoology. Entomology as a science is extremely broad in its interpretation. Technically, any form of scientific study in which there is a focus on insect-related inquiries can be defined as entomology. Despite human interaction with insects throughout human societies from prehistory to today, the scientific study of insects experienced a slow and irregular start. In the 1st century BC, Aristotle published a text, Historia Animaālium, in which Book 4 detailed animals without blood, the non-vertebrates. In that book, he includes insects as class Entoma. The current class, Insecta, is the Latin translation of Aristotle's Entomon. The 11th century demonstrated a written record of the understanding that some predatory insects can protect crops (Needham et al., 2000). Entomology as a studied discipline did not start until the 16th century (Saltini, 1989). In the 17th and 18th centuries, entomology matured as a science, with many works being published that encompassed systematics, developmental biology, anatomy, and physiology.
