Taxonomy – Importance, History and Development

Taxonomy – Importance, History and Development Taxonomy is the process of identifying and classifying living organisms. Taxonomists study organisms and identify them based on their characteristics. These characteristics might be visible morphological characteristics or genetic differences. The binomial naming system is the system used to name species. Each species is given a name that consists […]

Structure and Functions of Respiratory System

Structure and Functions of Respiratory System Similar to aerobic animals, insects must obtain oxygen from their environment and eliminate carbon dioxide respired by their cells. This is gas exchange through series of gas filled tubes providing surface area for gaseous exchange (Respiration strictly refers to oxygen consuming, cellular metabolic processes). Air is supplied directly to […]

Structure and Functions of Excretory System

Structure and Functions of Excretory System Different types and their functional mechanisms The removal of waste products of metabolism, especially nitrogenous compounds from the body of insects is known as excretion. The excretion process helps the insect to maintain salt water balance and thereby physiological homeostasis. Following are the excretory organs. 1. Malpighian tubules Thin, […]

Structure and Functions of Digestive System

Structure and Functions of Digestive System The alimentary canal of insects is a long, muscular, and tubular structure extending from mouth to anus. It is differentiated into three regions viz., Foregut, Midgut and Hindgut. I. FOREGUT Foregut is ectodermal in origin. Anterior invagination of ectoderm forms foregut (Stomodeum). Internal cuticular lining is present. Terminal mouth […]

Order – Orthoptera Family – Acrididae

Order – Orthoptera Family – Acrididae Orthoptera Synonyms: Saltatoria, Saltatoptera Etymology: Ortno – straight; ptera-wings. Common names: Grasshoppers, Locust, Katydid, Cricket, Mole cricket Characters Classification This order is sub divided into two suborders, viz., Caelifera and Ensifera. Sound production is alary type. A thick region on the hind margin of the forewing (scraper) is rubbed […]
